Essential Ingredients for Perfect Lucky Charms Vanilla Buttercream Macarons
When you’re dealing with French pastry, ingredients are everything. You can’t just throw things together and hope for the best here. Measuring everything precisely is how we ensure our Lucky Charms Vanilla Buttercream Macarons get those beautiful, flat bottoms and perfect little ruffled edges—the ‘feet’ everyone fights over! Getting the dry ingredients super fine is my non-negotiable rule, just like when I make my favorite scones a lot of the time. I’ve found that a little bit of prep work here, much like the careful mixing you need for secrets to perfect scones, really pays off in the end.
For the Macaron Shells
You absolutely need to sift these dry ingredients. Don’t skip that step; that’s where the refined texture comes from. And if you can, use egg whites that have been sitting out overnight—they whip up so much better and give you more stable meringue peaks.
- 150 g Almond flour, make sure it’s finely sifted!
- 150 g Icing sugar
- 110 g Egg whites (aged if possible, seriously!)
- 40 g Sugar
- 1 g Salt
For the Vanilla Buttercream Filling
This is where the fun hits the grown-up pastry. We want the buttercream smooth and creamy so it holds those crunchy cereal bits without feeling gritty. Remember, the butter needs to be perfectly softened, not melted, for that smooth creamed texture.
- 115 g Unsalted butter, softened to room temperature
- 150 g Icing sugar
- 10 ml Vanilla extract
- 10 g Crushed Lucky Charms marshmallows (These are our secret weapon for texture and flavor!)
Step-by-Step Guide to Making Lucky Charms Vanilla Buttercream Macarons
This is the part where we turn our careful prep work into beautiful, delicate cookies! Look, making macarons requires focus, but if you follow these steps exactly, you’ll get those glorious little feet every single time. We’re going to cover the dreaded macaronage—the folding part—which is truly the secret sauce. Once they’re baked, we’ll get to the fun part of mixing in those colorful little cereal marshmallows into the filling. If you want a deep dive into getting those feet right, check out my guide on how to make mini macarons!
Preparing the Macaron Shells
First things first, prep your tools! Get your baking sheets lined with parchment paper or silicone mats. Grab a pencil and draw out those little circles—about 3.5 cm across—as guides. You need to make sure your dry ingredients are totally smooth, so sift your almond flour and icing sugar together twice. No lumps allowed; they ruin the whole look!
Now for the meringue part. Get your egg whites foaming on medium speed in a clean bowl, and sprinkle in that salt. Once they look bubbly, start adding the sugar little by little. You need to beat this until you reach stiff, shiny peaks. When you lift the whisk, the meringue should stand straight up proudly. That’s perfection!
The folding, or macaronage, is crucial. Take your dry mix and fold it into the meringue in three small batches. You are aiming for the ‘thick lava’ consistency. Fold gently but deliberately until the batter flows slowly off your spatula in a ribbon that seems to disappear back into itself after about 20 seconds. If it flows too fast, you’ve added too much air—oops! Once it’s there, stop! Don’t overmix, or you’ll lose the structure entirely.
Pipe the batter neatly onto your oiled circles. Now, this next bit is vital: pick up those trays and SMACK them flat on the counter several times. I mean it, really whack them! This forces those sneaky air bubbles trapped inside to rush to the surface. Let them sit out for a good 30 to 40 minutes until they form a dry skin on top. You should be able to lightly touch the surface without any batter sticking to your finger.
Baking and Cooling the Shells
Preheat your oven to exactly 150°C. I bake these one sheet at a time so the temperature stays consistent. Slide them in for about 13 to 15 minutes. Watch them closely! You want to see those delicate ‘feet’ rise up around the base of the shell. Once they’re done, leave them completely alone on the tray until they are totally cool—we’re talking cold—before attempting to peel them off. If they stick, they aren’t ready yet!
Assembling the Lucky Charms Vanilla Buttercream Macarons
While those shells are chilling out, let’s make the filling. Beat that softened butter until it’s fluffy, then slowly beat in the icing sugar and the vanilla extract until it’s smooth as silk. This is where I’m really careful—I want that creamy base! Only once the buttercream is perfect do you gently fold in your crushed Lucky Charms marshmallows. We fold these in last so they stay crunchy little surprises inside the vanilla cloud.
Time to pair them up! Look through your shells and match up the ones that are roughly the same size. Pipe a nice dollop of that buttercream onto one shell—use your piping bag again to keep it neat—and gently sandwich it with its mate. Don’t press too hard, or you’ll squeeze all the filling out the sides!
This step is often rushed, but don’t you dare skip it! You need an extra 30 minutes minimum of chilling time after assembly. This allows the moisture from the buttercream to soften the inside of the shell slightly, giving you that melt-in-your-mouth texture we are aiming for with these **Lucky Charms Vanilla Buttercream Macarons**.
Tips for Success with French Macarons
Look, French macarons are not forgiving, and I’m not going to pretend they are! I’ve had batches that looked perfect come out of the oven looking like sad, flat pancakes. It happens to everyone, even me, and I bake them constantly. The key to conquering the macaron game is understanding the environmental factors that mess with the delicate meringue structure. If you want to know more about the difference between the French style and the Italian style, I wrote a whole piece on are Italian or French macarons better, but for these—sticking to the French meringue method is key!
Here are the few things that I check obsessively before I even think about turning on my oven:
- Humidity is the Enemy: If it’s raining, if your kitchen is steamy, or if you live somewhere super humid, maybe save this recipe for a dryer day. Moisture stops that crucial skin from forming during the rest time. If your shells won’t dry, they won’t get feet, simple as that.
- The Air Bubble Tap: I mentioned this above, but I can’t stress it enough—tap, tap, tap that baking sheet! If you see a tiny bubble rise up after you tap, use the tip of a toothpick to pop it right away. Those tiny trapped pockets of air turn into giant craters when baking.
- Getting Those Perfect Feet: The ‘feet’—that little ruffled skirt around the base—form when the batter underneath puffs up while the top skin sets. If you don’t get feet, it usually means one of two things: either you didn’t let the shells rest long enough to form that proper skin, or your oven temperature was too low or too high. Keep an eye on the temperature fluctuations in your own oven!
- Sifting is Non-Negotiable: I know it’s tedious running that almond flour and powdered sugar through the sifter twice, but if you skip it, those little lumps will bake into bumps on your shells. We want smooth domes, not meringue mountains!
Don’t stress if your first batch isn’t magazine-perfect. Macarons teach you patience. Just taste the shells—even if they look a little wonky, they’ll still taste amazing sandwiched with that vanilla buttercream!

They look absolutely stunning next to traditional spreads, maybe balancing out some heavier St Patty Day Food like corned beef sliders or rich dips.

If you need even more inspiration for your spread, I’ve got tons of ideas over in my holiday party recipes section!
Ideas for St Patrick’s Day Snacks For Kids
While these are refined enough for the adults, let’s be real: the marshmallows are calling the little ones! These make the absolute best St Patrick’s Day Snacks For Kids because they instantly recognize the cereal bits. They are so much easier to manage than messy cupcakes or brownies when you’re wrangling a bunch of excited kids at a party. They feel like their favorite cereal turned fancy!
When setting up a table just for the children, make sure these are prominent! They are far more fun than standard cookies. I think calling them the official St Patrick’s Day For Kids Treats is totally fair game. Since they are small, they are portion-controlled, which is always a bonus when you’re trying to keep things manageable. Plus, the kids love helping you pick out the shells that look the best—it makes them feel included in the baking adventure!
Storage and Reheating Instructions for Your Lucky Charms Vanilla Buttercream Macarons
Whew! You made them! Now, we need to make sure these delicate little treasures last—and taste perfect when you finally decide to eat them. Macarons aren’t like chocolate chip cookies; you can’t just leave them on the counter for a week. They need proper care, especially since we’ve got that creamy vanilla buttercream filling inside our Lucky Charms Vanilla Buttercream Macarons.
The good news is that macarons actually get better after a day or two in the fridge. That resting time allows the moisture from the filling to gently soften the crispness of the shell just enough, creating that perfect texture that melts right in your mouth. Don’t worry about storage, it’s easier than you think!
Refrigeration Guidelines for Maximum Freshness
Once you’ve assembled the macarons, you want to pop them into the refrigerator ASAP. Make sure they are in an airtight container. I usually use one of those plastic containers that has a tight-fitting lid, or I’ll layer them between silicone mats in a shallower container—just be gentle when closing the lid so you don’t crush the tops!
Do you know how long they last? If kept sealed tightly in the fridge, they hold up beautifully for about five days. Seriously, five days of perfect, creamy **Lucky Charms Vanilla Buttercream Macarons** waiting for you! They really do keep well, which is great if you’re prepping for a big event like a party.
If you need to store them longer, you can freeze them! Place the sealed container in the freezer for up to a month. Just make sure they defrost slowly in the fridge overnight before you plan to serve them, otherwise, condensation can mess with the shells.
Bringing Them Back to Perfect Texture
This step is non-negotiable if you want that dream texture. If you eat a chilled macaron straight from the fridge, the shell will be too hard, and the filling will feel stiff. We need to wake them up!
Take the container of **Lucky Charms Vanilla Buttercream Macarons** out of the refrigerator about 20 to 30 minutes before you plan on serving them. Set the container on the counter and let them come to room temperature slowly. This slight warming allows the butter in the filling to soften back to that creamy texture while the shell relaxes just enough to have that beautiful delicate snap when you bite into it.
This little waiting period is totally worth it. It transforms them from ‘good cold macaron’ to ‘heavenly **Lucky Charms Vanilla Buttercream Macarons**.’ If you’re struggling with making desserts ahead of time or need more general advice on keeping sweet treats perfect, you might want to browse some of the tips I’ve put together in my desserts category!
Equipment You Need for Macaron Success
If you’ve made it this far, you know that macarons demand respect, and that means bringing out the right tools for the job. You can’t really fake precision when you’re making delicate French pastry like this! I always set up my station before I even look at the eggs; having everything clean, measured, and ready to go prevents those panic moments when you’re supposed to be folding batter, not hunting for a clean bowl. Believe me, having the right gear makes the entire process infinitely smoother.
We don’t need a million gadgets, but the ones we do use have to be up to snuff. This preparation shows that you recognize the delicate nature of French baking—that’s part of the expertise we bring to the table!
- Baking Sheets: You need reliable, flat baking sheets. If your pans warp in the oven, your shells won’t bake evenly, which means sad, patchy feet across the bottom. Two sturdy, light-colored sheets are ideal since we bake these one tray at a time.
- Parchment Paper or Silicone Mats: This is hugely important! You cannot skip lining the trays. I love silicone mats (like Silpat) because they give that perfect, consistent non-stick surface. If you use parchment, make sure it’s smooth and you tape the corners down so it doesn’t buckle.
- A Good Sifter: I use a fine-mesh sieve for everything in this recipe, especially for sifting the almond flour and icing sugar not once, but twice! Those little lumps we talked about? They get caught right here. Don’t use a colander; you need finer mesh than that.
- Piping Bag and Tip: You need a steady way to get those shells exactly the same size, so a piping bag is a must. I use a plain round tip, usually about 1/2 inch wide, to pipe my circles. This helps keep the batter consistent from one shell to the next.
- Scrapers and Spatulas: You’ll need a sturdy rubber spatula for the careful folding process (the macaronage) and maybe a small offset spatula for spreading the filling later on.
Frequently Asked Questions About Lucky Charms Vanilla Buttercream Macarons
I get asked about these colorful little beauties all the time! Since making macarons requires a little more precision than whipping up a standard cookie, readers always have great follow-up questions. I’ve gathered the most common ones here to help you nail your batch of Lucky Charms Vanilla Buttercream Macarons on the very first try. Making these is totally achievable, no matter your experience level!
Can I substitute the almond flour in this recipe?
Oh, my dear, please don’t try to substitute the almond flour! I know it can be expensive, but almond flour is absolutely essential for the texture of French macarons. It’s what gives the shell that perfect chewiness and that classic melt-in-your-mouth quality we love. If you use regular all-purpose flour, you’ll end up with a meringue cookie, not a macaron—the texture is just totally different because the fat content and granular structure aren’t the same. It’s worth investing in good quality, finely ground almond flour for this recipe.
How do I keep the marshmallows from dissolving in the buttercream?
This is a fantastic question, especially since we are working with cereal pieces mixed into butter and sugar! The trick to keeping those rainbow bits crunchy in your vanilla buttercream is twofold. First, you have to crush them quite finely—we don’t want big chunks that throw off the structure. Second, and this is the most important part, you fold them in right at the very end of the mixing process. You want the butter and sugar totally emulsified and smooth first. Then, you gently fold in the crushed marshmallows just until they are distributed and stop stirring immediately. This prevents them from getting overworked and dissolving into the fat before they even hit the shell!
Are these considered good St Patrick’s Day Appetizers?
That’s a fun way to think about our Lucky Charms Vanilla Buttercream Macarons! Technically, they are dessert treats, but because they are small, colorful, and easy to nibble on while mingling, they work amazingly well as part of a larger buffet spread for a St Patrick’s Day Party. I see them more as the grand finale to your St Patrick’s Day Food Ideas spread. They are definitely much more elegant than something like green Jell-O squares. They look so vibrant scattered around that they fit right in with any festive Green Snacks you might be serving, and kids especially love them as the sweet reward after all those savory St Patrick’s Day Snacks For Kids!
