How to Make Banana Crumb Coffee Cake:
Ready to bake? This Banana Crumb Coffee Cake is surprisingly easy to make, even for beginner bakers! The moist banana cake is quick to whip up, and the crumb topping comes together in minutes. The combination of textures and flavors is truly amazing, and it’s ready in about an hour!
Step-by-Step Instructions:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch square baking pan. This ensures the cake comes out easily!
- Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Whisking is key to evenly distribute leavening agents.
- Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. This step is crucial for a tender cake.
- Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract. Make sure each egg is fully incorporated.
- Mix Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the mashed bananas and sour cream, beginning and ending with the dry ingredients. Mix until just combined. Don’t overmix! Overmixing leads to a tough cake.
- Prepare the Crumb Topping: In a separate bowl, combine the flour, brown sugar, granulated sugar, cinnamon, and salt. Make sure there are no lumps!
- Cut in the Butter: Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Cold butter is essential for a crumbly topping.
- Assemble the Cake: Pour the batter into the prepared baking pan. Sprinkle the crumb topping evenly over the batter.
- Bake: Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. The baking time may vary, so keep an eye on it!
- Cool and Serve: Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Cooling it slightly in the pan helps it set. Cut into squares and serve.
