Frequently Asked Questions

→ Can I use frozen bananas for this recipe?
Yes, frozen bananas work great in this recipe. Just thaw them completely and drain any excess liquid before mashing. The riper the bananas, the sweeter and more flavorful your brownies will be.
→ Why do my brownies need sour cream?
Sour cream adds moisture and richness to the brownies. It helps create that perfect fudgy texture and keeps the brownies from drying out. You can substitute Greek yogurt if you don't have sour cream.
→ How do I know when the brown butter is ready?
Brown butter is ready when it turns golden brown and smells nutty. Watch it carefully as it can quickly go from perfect to burnt. The butter will foam up first, then the foam will subside and brown bits will form at the bottom.
→ Can I make these brownies ahead of time?
These brownies can be made 1-2 days ahead of time. Store them in an airtight container at room temperature. You can also freeze them unfrosted for up to 3 months and add the frosting after thawing.
→ What's the best way to cut these brownies?
Let the brownies cool completely before cutting. Use a sharp knife and clean it between cuts for the neatest squares. If you want extra clean cuts, refrigerate the brownies for an hour after frosting.

These banana bread brownies are a delightful fusion of two classic desserts. By combining the rich, fudgy texture of brownies with the sweet, moist essence of banana bread, this recipe creates a unique and irresistible treat.
