Equipment

  • Mixing Bowls
  • Loaf pan or cake pan

Ingredients
  

For the Cake Batter

  • 2 cups flour
  • 1 tsp baking soda
  • 3 bananas, mashed
  • 1/2 cup butter
  • 3/4 cup sugar
  • 2 eggs
  • 1 tsp vanilla extract

For the Chocolate Swirl

  • 1/4 cup cocoa powder Mixed with a small amount of the batter

Instructions
 

  • Prepare the main banana batter by combining the flour and baking soda. In a separate bowl, cream the butter and sugar, then beat in the eggs and vanilla. Mix the wet ingredients into the dry ingredients, then fold in the mashed bananas.
  • Divide the banana batter in half. Mix the cocoa powder into one half until fully combined.
  • Pour the batters alternately into your prepared pan. Use a knife or skewer to gently swirl the chocolate batter through the banana batter to create a marble pattern.
  • Bake at 175°C for 45 to 50 minutes, or until a toothpick inserted into the center comes out clean.
  • Allow the cake to cool completely before slicing. Slice to show the swirl pattern when serving.
