Step‑by‑Step Instructions for Banana Crumb Coffee Cake With Easy Streusel Topper
Step 1: Preheat the Oven and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare an 8×8-inch baking pan by greasing it with butter or lining it with parchment paper. This ensures your Banana Crumb Coffee Cake will come out effortlessly once baked, giving you a perfect surface to showcase that delicious crumbly topping.
Step 2: Combine Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This dry mixture will create a solid foundation for your cake. Make sure to combine them thoroughly, as this step is crucial for evenly distributing the leavening agents and enhancing the texture of your Banana Crumb Coffee Cake once baked.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the softened unsalted butter and granulated sugar together until the mixture is light and fluffy, about 2-3 minutes. This process incorporates air into the batter, contributing to a tender, fluffy cake. A stand mixer or hand mixer will work wonders at this stage, blending the ingredients seamlessly together.
Step 4: Add Eggs and Flavors
Next, add the eggs one at a time to the creamed butter and sugar, mixing well after each addition. Stir in the vanilla extract and mashed ripe bananas along with the sour cream until everything is just combined. The mixture should have a lovely, slightly chunky texture from the bananas, which will add moisture and delight to your cake.
Step 5: Incorporate Dry Mixture
Gradually fold the dry ingredient mixture into the wet ingredients using a spatula until just combined. Be gentle to avoid overmixing, which can lead to a dense cake. The final batter should be thick and smooth, with bits of banana visible, ready to be poured into your prepared pan for the delicious Banana Crumb Coffee Cake.
Step 6: Transfer Batter to Pan
Pour the prepared cake batter into the greased or lined baking pan, using a spatula to smooth the top. This ensures an even baking surface for your Banana Crumb Coffee Cake. Spread the batter out evenly, which helps the cake to rise uniformly and allows the streusel topping to adhere beautifully when sprinkled on.
Step 7: Make the Streusel Topping
In a small bowl, mix together the flour, brown sugar, cinnamon, and salt for the streusel topping. Once combined, pour in the melted unsalted butter and stir until the mixture is crumbly. The texture of this streusel will create that satisfying crunch atop your cake, complementing its soft, fluffy interior wonderfully.
Step 8: Sprinkle the Topping
Evenly sprinkle the prepared streusel topping over the batter in the baking pan. It’s important to cover the batter completely, ensuring each bite of your Banana Crumb Coffee Cake will be deliciously infused with sweet crunch. This step adds visual appeal and irresistible texture to your baked treat.
Step 9: Bake the Cake
Place the baking pan in the preheated oven and bake for 40-45 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with just a few crumbs clinging to it. The cake will be golden brown on top, signaling that your Banana Crumb Coffee Cake is ready to be enjoyed.
Step 10: Cool and Serve
Allow the coffee cake to cool in the pan on a wire rack for 15 minutes before slicing. This resting time lets it set, making it easier to cut into neat squares. Serving your warm, fluffy Banana Crumb Coffee Cake will surely bring smiles to everyone at your gathering, especially accompanied by a steaming cup of coffee!

Tips for the Best Banana Crumb Coffee Cake
Ripe Bananas: Use overripe bananas for the sweetest flavor. If they’re green, place them in a paper bag to speed up the ripening process.
Gentle Mixing: Be sure not to overmix your batter after adding the dry ingredients. This helps maintain the soft, fluffy texture of the banana coffee cake.
Watch the Streusel: Keep an eye on the streusel while baking, as it can brown quickly. If it darkens too fast, cover with foil to prevent burning.
Temperature Check: Always test the cake with a toothpick to ensure it’s done; it should come out clean or with a few crumbs—this guarantees a delightfully moist crumb.
Storage Tips: For any leftovers, store in an airtight container at room temperature for up to 3 days. This keeps your Banana Crumb Coffee Cake fresh and delicious!
