Step‑by‑Step Instructions for Sourdough Banana Cake with Cinnamon Maple Frosting

Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms, take an 8-inch square baking pan and generously grease it with butter. Then, line the bottom with parchment paper for easy removal once your Sourdough Banana Cake is baked.

Step 2: Brown the Butter
In a medium saucepan over medium heat, melt the unsalted butter slowly. Continue cooking it for about 5-7 minutes, swirling occasionally until it turns golden brown and emits a nutty aroma. This step enhances the flavor, so watch closely to avoid burning. Set it aside to cool slightly.

Step 3: Combine Wet Ingredients
In a large mixing bowl, combine the cooled brown butter with brown sugar and vanilla extract. Stir until the mixture is well integrated, then add in the large eggs, ripe bananas, sourdough discard, and buttermilk. Whisk thoroughly until the mixture is smooth and creamy, showcasing that delightful banana flavor.

Step 4: Mix Dry Ingredients
In a separate bowl, sift together all-purpose flour, baking soda, baking powder, and salt. This ensures there are no lumps and the dry ingredients are evenly mixed. Gradually fold these dry ingredients into the wet batter, taking care to mix gently until just combined for a tender crumb in your Sourdough Banana Cake.

Step 5: Bake the Cake
Pour the batter into the prepared pan, spreading it evenly with a spatula. Place the pan in the preheated oven and bake for 25-30 minutes. Keep an eye on it; the cake is done when a toothpick inserted in the center comes out clean, and the top is golden brown.

Step 6: Cool the Cake
Once baked, remove the pan from the oven and let the cake cool in the pan for about 20 minutes. After cooling, carefully transfer the Sourdough Banana Cake to a wire rack to cool completely before frosting. This allows the cake to set nicely for the next delicious step!

Step 7: Prepare the Frosting
In a large bowl, beat together the softened cream cheese and unsalted butter using a hand mixer until fluffy. Gradually add in powdered sugar, maple syrup, vanilla extract, ground cinnamon, and a pinch of salt. Mix well until the frosting is smooth, creamy, and perfectly sweet.

Step 8: Frost the Cake
Once the Sourdough Banana Cake is completely cool, spread the cinnamon maple cream cheese frosting generously over the top. For a finishing touch, you can swirl in a drizzle of extra maple syrup to enhance the flavor, adding a beautiful visual appeal to this delightful dessert.

Make Ahead Options

These Sourdough Discard Banana Cakes are a fantastic choice for meal prep! You can prepare the cake batter up to 24 hours in advance by mixing all the wet and dry ingredients and chilling it in the fridge. This not only enhances the flavors but also saves you time on busy days. Additionally, the cake can be baked and stored in an airtight container for up to 3 days. For the best texture, allow the cake to come to room temperature before serving. When you’re ready to indulge, simply whip up the cinnamon maple cream cheese frosting just before serving, ensuring your dessert remains just as delicious and fresh!

Tips for the Best Sourdough Banana Cake

Brown Butter Wisely: Watch your butter closely as it browns; it can go from perfectly nutty to burnt very quickly if not attended to.
Ripe Bananas are Key: Opt for overripe bananas; the more speckled they are, the sweeter and moister your sourdough banana cake will be.
Avoid Overmixing: Gently fold in dry ingredients just until combined; overmixing can lead to a dense texture instead of the desired lightness.
Chill the Batter: If you have time, let the batter sit in the fridge for an hour before baking. This allows the sourdough flavors to deepen.
Check Freshness: Always ensure your baking soda and baking powder are fresh; expired leavening agents can impact the rise and texture of your cake.
