eggs

baking soda
salt

For the crumb topping:

Directions

Preheat your oven to 350°F (175°C) and prepare a baking pan by greasing it or lining it with parchment paper.

In a mixing bowl, mash the ripe bananas until smooth. Set aside.

In another bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and mashed bananas.

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, alternating with the milk, and mix until just combined.

Pour the batter into the prepared pan and spread it evenly.

To make the crumb topping, combine flour, sugars, and cinnamon in a bowl. Cut in the butter until the mixture resembles coarse crumbs.

Sprinkle the crumb topping evenly over the cake batter.

Bake for 35 to 45 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cake to cool before slicing and serving.
