tips to make Banana Bread Brownies with Brown Butter Frosting
- Use very ripe bananas for the best flavor. The riper the banana, the sweeter and more flavorful your brownies will be.
- Make sure to allow the brownies to cool completely before spreading the frosting. This will prevent the frosting from melting off.
- If you want a thicker frosting, simply add a little more powdered sugar until you reach your desired consistency.
