Step‑by‑Step Instructions for Banana Crumb Coffee Cake With Easy Streusel Topper
Step 1: Preheat Oven and Prepare Pan
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare an 8×8-inch square baking pan by greasing it with butter or non-stick spray. For added protection, you can line the bottom with parchment paper, ensuring effortless removal of your moist Banana Crumb Coffee Cake later.
Step 2: Mix Dry Ingredients
In a medium-sized bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and a pinch of salt. This mixture of dry ingredients will add structure to your cake. Set this aside to let the flavors come together while you work on the wet ingredients.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat together ½ cup of softened unsalted butter and ¾ cup of granulated sugar. Use a hand mixer on medium speed for about 2-3 minutes until the mixture is light and fluffy. This step is crucial for creating a deliciously tender Banana Crumb Coffee Cake, as the air incorporated will help it rise beautifully.
Step 4: Incorporate Eggs and Bananas
Slowly add 2 large eggs to the butter and sugar mixture, one at a time, mixing well after each addition. Then, stir in 1 cup of mashed ripe bananas and ½ cup of sour cream until everything is well combined. The bananas add both moisture and flavor, creating a delightful base for your cake.
Step 5: Combine Wet and Dry Mixtures
Gradually add the reserved dry ingredients to the banana mixture, using a spatula to fold them in gently. Mix just until combined; be careful not to overmix, as this could lead to a dense cake. You want your Banana Crumb Coffee Cake to remain light and fluffy, with a tender crumb.
Step 6: Pour Batter into Pan
Once your batter is ready, pour it into the prepared baking pan and gently smooth the top with a spatula. Make sure the mixture is evenly spread to ensure even baking. This step is essential for achieving that perfect fluffy texture throughout your cake.
Step 7: Prepare the Streusel Topping
In a small bowl, combine ½ cup of all-purpose flour, ½ cup of brown sugar, ½ teaspoon of ground cinnamon, and a pinch of salt. Pour in ¼ cup of melted unsalted butter and stir until the mixture resembles coarse crumbs. This easy streusel topping will add a crunchy sweetness to your Banana Crumb Coffee Cake.
Step 8: Add Streusel to Cake Batter
Sprinkle the prepared streusel evenly over the top of the banana batter in the pan. Ensure that the topping covers the batter well, as this will caramelize and provide a charming crunch while baking. Your cake is now ready for the oven to become a delicious treat!
Step 9: Bake the Cake
Place the baking pan in the preheated oven and bake for 40-45 minutes. Start checking for doneness at the 40-minute mark by inserting a toothpick into the center of the cake; it should come out clean or with just a few moist crumbs. The cake will be golden brown and will smell delectable!
Step 10: Cool and Serve
Once baked, remove the Banana Crumb Coffee Cake from the oven and let it cool in the pan for 15 minutes. This brief cooling time makes it easier to slice. After cooling slightly, cut the cake into squares and serve warm or at room temperature, enjoying the delightful textures of cake and streusel.

Banana Crumb Coffee Cake with Easy Streusel Topper Recipe FAQs
How do I select ripe bananas for this recipe?
Absolutely! The best bananas for your Banana Crumb Coffee Cake are those that are very ripe, with plenty of brown spots or even completely brown skin. These bananas are sweeter and softer, making them perfect for moistening your cake. If you don’t have ripe bananas on hand, you can speed up the ripening process by placing them in a paper bag at room temperature.

Very! To keep your Banana Crumb Coffee Cake fresh, store any leftovers in an airtight container at room temperature for up to 3 days. If you want to extend its shelf life, you can refrigerate it for up to a week. Just make sure it’s wrapped well to maintain its moistness.

What if my cake doesn’t rise properly?
Very often, a cake’s failure to rise typically results from either expired leavening agents or overmixing the batter. Always check that your baking powder and baking soda are fresh. When combining the wet and dry ingredients, fold gently until just combined to avoid developing excess gluten, which can make the cake dense.
Are there any dietary considerations for this recipe?
Absolutely! If you’re accommodating dairy-free or gluten-free diets, you can make several substitutions. For a dairy-free version, use coconut oil or a vegan butter substitute, and replace sour cream with almond or soy yogurt.

Always double-check any specific allergies amongst your guests to ensure everyone can enjoy this delightful treat!
Can I incorporate nuts or chocolate into the recipe?
Very much so! For added flavor and crunch, consider mixing in chopped nuts such as walnuts or pecans directly into the batter or streusel. You could also fold in chocolate chips for a sweet twist. Feel free to get creative and tailor this Banana Crumb Coffee Cake to your taste preferences!
