Step-by-step Preparation of Brown Butter Banana Coffee Cake
Creating a brown butter banana coffee cake is a delightful experience that blends rich flavors and a soft, moist texture. Follow these simple steps to create your cake and impress anyone lucky enough to share it with you!
Preheat the oven and prepare the baking pan
Start by preheating your oven to 350 degrees Fahrenheit. While it's warming up, grab an 8x8-inch square baking pan and line it with parchment paper. Make sure to let the parchment hang over the edges to help with easy removal later. This little trick is a game changer for keeping your cake intact!
Brown the butter to enhance flavor
The secret to an incredible brown butter banana coffee cake lies in the browned butter. To do this, melt 6 tablespoons of unsalted butter over medium heat in a saucepan, stirring often. As it melts, it will begin to foam. Keep stirring until it turns a lovely golden brown and emits a nutty aroma. If you’ve never browned butter before, check out this guide to master the technique!
Make the streusel topping
Next, let’s whip up that delicious streusel topping. In a bowl, mix together ⅓ cup of all-purpose flour, ¼ cup of packed light brown sugar, and ½ teaspoon of ground cinnamon. Ensure there are no lumps by breaking them up with your fingers. Add 3 tablespoons of very soft salted butter and rub it into the mixture until it forms soft crumbs. You can set this aside while you move on to the next step.
Prepare the banana batter
In a separate bowl, mix 1 ¼ cups of all-purpose flour, ½ teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. In another large mixing bowl, mash about 2 medium ripe bananas and whisk in ⅔ cup of packed light brown sugar until smooth. Integrate 1 large egg, ⅓ cup of full-fat sour cream, the cooled browned butter, and 1 teaspoon of pure vanilla extract. Finally, gently fold in the dry ingredients using a rubber spatula until just combined.
Spread the batter and add cinnamon sugar
Spoon about two-thirds of the banana batter into your prepared baking pan, smoothing it out evenly. Now, sprinkle a mixture of 3 tablespoons of brown sugar, 1 teaspoon of cinnamon, and 1 teaspoon of cocoa powder over the batter for that delightful gooey swirl. Add dollops of the remaining batter on top and gently spread them together.
Add the streusel topping and bake
Sprinkle the prepared streusel topping evenly over the cake. Bake in your preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Once it’s done, allow it to cool in the pan on a wire rack.
Prepare the vanilla glaze
For the finishing touch, whisk together ½ cup of powdered confectioner’s sugar, 1 tablespoon of whole milk, and ¼ teaspoon of ground cinnamon in a small bowl. If the glaze is too thick, add a little more milk, half a teaspoon at a time. Once your cake is slightly warm, drizzle the glaze over the top.
Enjoy this brown butter banana coffee cake with your favorite cup of coffee and share it with friends or keep it all to yourself—because who could resist such a delicious treat?

Variations on Brown Butter Banana Coffee Cake
Chocolate Chip Banana Coffee Cake
For a delightful twist on the classic brown butter banana coffee cake, consider adding semi-sweet chocolate chips. Simply fold in a cup of your favorite chocolate chips into the batter before pouring it into the pan. The rich, melty chocolate complements the sweetness of the bananas perfectly, creating a decadent dessert that chocolate lovers will adore. Don’t forget to sprinkle a few chocolate chips on top before baking for an extra visual treat.
Nutty Banana Coffee Cake
If you’re a fan of textures, try adding chopped walnuts or pecans to your cake. Nuts bring a wonderful crunch that balances beautifully with the moist banana and buttery flavors. Just fold in about half a cup of your chosen nuts into the batter before spreading it in the pan. Toasting the nuts lightly beforehand can also intensify their flavor and give your brown butter banana coffee cake an extra layer of richness.
These variations not only enhance the flavor but also allow you to customize the cake to your taste preferences. Whether you're leaning towards chocolatey decadence or nutty crunchiness, these twists ensure your coffee cake is always a hit!
Cooking Tips and Notes for Brown Butter Banana Coffee Cake
Perfecting the Brown Butter
To achieve that rich, nutty flavor in your brown butter banana coffee cake, watch your butter closely as it cooks. Stir it constantly to prevent burning, and remove it from heat once it turns a deep amber color. This will elevate your cake's flavor profile immensely.

Ensuring the Right Texture for the Batter
Texture is key for this coffee cake! Make sure your bananas are very ripe—this means a lot of natural sweetness and moisture. When mixing your ingredients, fold the dry into the wet gently; overmixing can lead to a dense cake. If you want a thicker crumb topping, feel free to double your streusel recipe for an extra crunch on top!
