Banana Oatmeal Coffee Cake

Follow our step-by-step guide on how to make Banana Oatmeal Coffee Cake.

1. Step 1

   Begin by preheating your oven to a cozy 375°F (190°C) and lightly coat a 10-inch square baking pan with vegetable oil spray to ensure easy release.

2. Step 2

   In a small bowl, mix milk with white vinegar to create a tangy sour milk; stir gently and set it aside to thicken.

3. Step 3

   Next, take ripe bananas and mash them until you have about one cup of smooth goodness.

4. Step 4

   In a large mixing bowl, whisk together all-purpose flour, whole wheat flour, rolled oats, baking powder, baking soda, and salt, creating a wholesome dry blend.

5. Step 5

   In another bowl, use an electric mixer to cream unsalted butter and brown sugar until the mixture is light and fluffy.

6. Step 6

   Add in the eggs and a splash of vanilla extract, mixing until well combined, then fold in the mashed bananas for that delightful flavor.

7. Step 7

   Gradually incorporate the dry ingredients into the wet mixture in two parts, alternating with the sour milk, mixing just until everything is combined—avoid overmixing for a tender texture.

8. Step 8

   Pour the luscious batter into your prepared baking pan, spreading it evenly.

9. Step 9

   For the topping, combine brown sugar, all-purpose flour, and softened butter in a small bowl until crumbly, then stir in chopped pecans for a delightful crunch.

10. Step 10

    Sprinkle this topping generously over the batter, creating a tempting layer.

11. Step 11

    Bake in your preheated oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean, signaling that your creation is ready.

12. Step 12

    Once baked, let the cake cool on a wire rack before cutting it into squares, and enjoy the warm, comforting aroma that fills your kitchen.
