How to Make Irresistible Banana Bread Brownies with Brown Butter Frosting
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This step is crucial because it ensures even baking throughout your brownies. While it heats up, go ahead and grease and flour a 15×10 pan so that your delicious treats won’t stick!
Step 2: Mix the Base Ingredients
In a large bowl, beat together sugar, sour cream, softened butter, and mashed ripe bananas until creamy. This mixture creates the moist texture we love in banana bread brownies. Then stir in vanilla extract for that lovely aroma!
Step 3: Add Dry Ingredients
Next, mix in the all-purpose flour, baking soda, and salt until everything is well combined. If you’re using walnuts, now’s the time to fold them into the batter. The nuts add a nice crunch and flavor contrast!
Step 4: Bake Your Brownies
Pour the batter into your prepared pan and bake for about 20–25 minutes until golden. Keep an eye on them; you want them just right—moist but not undercooked!
Step 5: Make the Frosting
While your brownies are cooling slightly, let’s prepare that decadent brown butter frosting. In a saucepan over medium heat, melt your butter until it turns golden brown. This step adds such a rich flavor! Once browned, remove it from heat and stir in powdered sugar, vanilla extract, and milk until smooth.
Step 6: Frost Your Brownies
Spread the warm frosting over your brownies right after they come out of the oven. The warmth helps melt the frosting slightly into those delicious bars! Allow everything to cool before slicing into squares.
Now all that’s left is to enjoy each delightful bite of these Irresistible Banana Bread Brownies with Brown Butter Frosting!
Pro Tips for Making Irresistible Banana Bread Brownies with Brown Butter Frosting
Creating these delightful Banana Bread Brownies is a breeze, but a few tips can elevate your baking experience!
- Use overripe bananas: The riper the bananas, the sweeter and more flavorful your brownies will be. Look for bananas with brown spots or even fully brown skins for the best results.
- Don’t overmix the batter: Gently folding in the ingredients helps maintain a tender texture. Overmixing can lead to dense brownies that lose their lovely, moist quality.
- Let them cool before frosting: Allowing your brownies to cool slightly before adding the browned butter frosting prevents it from melting off and ensures a beautiful presentation when served.
- Experiment with mix-ins: Feel free to get creative! Add chocolate chips, dried fruits, or coconut flakes for extra flavor and texture. These additions can make each batch uniquely delicious.
- Store properly: To keep your brownies fresh and moist, store them in an airtight container at room temperature. They can also be frozen for up to three months—just thaw before serving!
