Preheat your oven to 200°C. Prepare your muffin tin.
Mix the flour and baking soda in one bowl. In another bowl, cream the butter and sugar together. Beat in the eggs one at a time.
Stir the mashed bananas into the wet ingredients.
Combine the wet and dry ingredients. Mix until just combined; do not overmix.
Fill the muffin cups high to achieve a bakery look.
Bake at 200°C for 5 minutes. Reduce the oven temperature to 180°C and bake for an additional 15 minutes, or until a toothpick inserted comes out clean.
Sprinkle sugar on top of the muffins immediately after removing them from the oven for a bakery finish.
