- 2-3 tablespoons milk

Equipment Needed
- 9-inch round cake pan or 8×8 inch square baking pan

- Electric hand mixer or whisk
- Measuring cups and spoons
- Rubber spatula
- Pastry cutter or fork (for streusel)
- Wire cooling rack
Recipe Preparation: Step-by-Step Instructions
Step 1: Prepare Your Workspace
Preheat your oven to 350°F (175°C). Grease your 9-inch round cake pan or 8×8 inch square baking pan with butter and lightly dust with flour, or line with parchment paper for easy removal. This banana coffee cake has a tendency to stick slightly due to the natural sugars in the bananas, so proper preparation is key.
Step 2: Prepare the Bananas
Select bananas that are perfectly ripe – they should have brown spots on the skin but not be completely black. Mash the bananas in a large mixing bowl until they’re mostly smooth with just a few small lumps remaining. The small chunks will add wonderful texture to your finished coffee cake.
Step 3: Mix the Wet Ingredients
Add the melted butter to the mashed bananas and stir well. Next, mix in the granulated sugar, beaten egg, and vanilla extract. The mixture should be well combined and slightly glossy. This forms the flavorful base of your banana cake recipe.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. This ensures even distribution of the leavening agent, which is crucial for achieving the perfect rise in your coffee cake.
Step 5: Create the Batter
Gradually fold the dry ingredients into the wet banana mixture, alternating with the sour cream and milk. Start and end with the flour mixture, mixing just until combined. Be careful not to overmix – a few streaks of flour are perfectly fine. Overmixing can result in a tough, dense cake rather than the tender crumb we’re after.
Step 6: Prepare the Streusel Topping
In a medium bowl, combine the flour, brown sugar, cinnamon, nutmeg, and salt for the streusel. Add the cold, cubed butter and use a pastry cutter or fork to work the butter into the dry ingredients until the mixture resembles coarse crumbs. This crumbly topping is what transforms a simple banana cake into an irresistible coffee cake.
Step 7: Assemble and Bake
Pour the batter into your prepared pan and spread it evenly. Sprinkle the streusel topping generously over the surface of the batter. Bake for 45-50 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs attached. The top should be golden brown and spring back lightly when touched.
Step 8: Cool and Glaze
Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack. If using the optional glaze, whisk together the powdered sugar, milk, and vanilla until smooth, then drizzle over the cooled cake.
Chef’s Tips and Tricks
Banana Selection and Preparation
The key to an exceptional banana coffee cake lies in using bananas at the perfect stage of ripeness. Choose bananas with yellow peels heavily spotted with brown – these provide maximum sweetness and flavor. If your bananas aren’t quite ripe enough, you can speed up the process by placing them in a paper bag with an apple overnight.
Moisture Secrets
The combination of sour cream and mashed bananas creates an incredibly moist coffee cake that stays fresh for days. If you don’t have sour cream on hand, you can substitute with Greek yogurt, though sour cream provides a slightly tangier flavor that complements the sweet bananas beautifully.
Streusel Perfection
For the best streusel topping, ensure your butter is cold when you begin. This creates those coveted crumbly pieces that add textural contrast to the soft cake beneath. If your kitchen is particularly warm, chill the butter cubes in the refrigerator for 10 minutes before incorporating them into the flour mixture.
Storage Tips
This banana coffee cake actually improves with time as the flavors meld together. Store covered at room temperature for up to 3 days, or wrap tightly and freeze for up to 3 months. For longer storage, omit the glaze until serving time.

Delicious Variations
Chocolate Chip Banana Coffee Cake
Fold ½ cup of mini chocolate chips into the batter before baking for an indulgent twist that chocolate lovers will adore.
Walnut Streusel Version
Add ½ cup of chopped walnuts to your streusel mixture for extra crunch and nutty flavor that pairs beautifully with bananas.
Healthier Options
Substitute half the all-purpose flour with whole wheat flour and reduce the sugar by ¼ cup for a slightly healthier version without sacrificing flavor.
Gluten-Free Adaptation
Replace the all-purpose flour with a 1:1 gluten-free flour blend for those with dietary restrictions.
Perfect Pairings
This versatile banana coffee cake pairs wonderfully with a variety of beverages and accompaniments. Serve warm slices with your morning coffee or afternoon tea. For a more indulgent treat, add a dollop of freshly whipped cream or a scoop of vanilla ice cream.
The cake also makes an excellent addition to brunch spreads alongside fresh fruit, yogurt parfaits, and egg dishes. Its sweet, comforting flavor provides a perfect balance to savory breakfast items.
