Best ways to enjoy it
These Banana Bread Brownies shine on their own, but there are so many delicious ways to serve them. Consider drizzling some melted chocolate over the top or dusting with powdered sugar for a simple finish. Pair them with a scoop of vanilla ice cream for an indulgent treat or serve them warm with a dollop of whipped cream for a special touch. They also make for a fantastic potluck dessert—just cut them into bite-sized squares for easier sharing!
Storage and reheating tips
To keep your brownies fresh, store them in an airtight container at room temperature for up to four days. If you want to extend their life, you can refrigerate them for up to a week. For longer storage, consider freezing. Simply wrap them in plastic wrap and then in foil before placing them in the freezer. They can be enjoyed for up to three months. When you’re ready to indulge again, just thaw them overnight in the fridge or warm them slightly in the microwave.
Helpful cooking tips
- For a richer flavor, allow your brownies to cool completely before frosting; it gives the frosting a chance to set beautifully.
- If you’re pressed for time, you can skip the frosting and enjoy the brownies as they are—still delicious!
- Ensure your bananas are truly ripe for the best flavor—brown spots are a good sign that they’re ready to be mashed!
Creative twists
Feeling adventurous? There’s always room to play with flavors! Consider adding a pinch of cinnamon for warmth or swapping out the walnuts for peanut butter chips for a new flavor profile. You can also experiment with different frostings—how about a cream cheese frosting instead of the standard vanilla? The possibilities are endless!
