01

Step

Preheat the oven to 375 degrees F (190 degrees C). Spray a 10-inch square baking pan with cooking spray. (5 minutes)

02

Step

Combine milk and vinegar in a glass to make sour milk; stir gently. Mash bananas in a small bowl to make 1 cup. (5 minutes)

03

Step

Combine all-purpose flour, whole wheat flour, oats, baking powder, baking soda, and salt in a bowl. (5 minutes)

04

Step

Cream butter and brown sugar in a large mixing bowl with an electric mixer until fluffy. Beat in eggs and vanilla extract. Mix in bananas. Add dry ingredients in 2 batches, alternating with sour milk; mix thoroughly. Pour batter into the prepared pan. (15 minutes)

05

Step

Mix brown sugar, flour, and butter for topping together in a bowl. Sprinkle topping over batter, then sprinkle on pecans. (5 minutes)

06

Step

Bake in the preheated oven until a toothpick inserted into the center comes out clean, 25 to 30 minutes. Cool on a wire rack before cutting into squares. (30 minutes)

For an extra layer of flavor, consider adding a pinch of cinnamon or nutmeg to the dry ingredients.
Ensure your bananas are very ripe for the best sweetness and moisture.
If you don't have whole wheat flour, you can substitute with all-purpose flour.
Let the cake cool completely before cutting for cleaner slices.
