Martha Stewart Banana Cake Ingredients
For the Cake:

- 1 ½ teaspoons baking powder
- 1 teaspoon baking soda
- ¾ teaspoon salt
- ¾ cup sugar
- ½ cup butter, melted (1 stick)
- ½ cup buttermilk, yogurt, or milk

How To Make Martha Stewart Banana Cake
- Prep the oven and mix dry ingredients: Preheat your oven to 300°F. In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar.
- Add melted butter: Pour in the melted butter and mix until the dry ingredients are moistened.
- Add part of the buttermilk: Mix in 1/4 cup of the buttermilk until blended.
- Combine eggs and buttermilk: In a separate bowl, whisk the remaining 1/4 cup of buttermilk with the eggs. Stir into the main batter.
- Add bananas and vanilla: Mix in the vanilla and mashed bananas. Beat the batter for 1 minute, then pour into a greased 9x13x2-inch baking pan.
- Prepare the topping: In a small bowl, squeeze together the flour, brown sugar, and butter with your hands to create a crumbly topping. Sprinkle evenly over the batter.
- Bake the cake: Bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean. Cool completely before serving.

Recipe Tips
- Can I use yogurt instead of buttermilk? Yes, plain yogurt works well as a substitute and keeps the cake moist.
- How ripe should bananas be for this cake? Use bananas that are heavily speckled or mostly brown for the best flavor and sweetness.
- How to know when banana cake is done: Insert a toothpick in the center—it should come out clean or with a few moist crumbs.
- Can I add nuts or chocolate chips? Yes, fold in about 1/2 cup of chopped nuts or chocolate chips before baking if you like.
- Why bake at 300°F? The lower temperature helps the cake bake more evenly and stay tender.
