Serving and Storage Tips
- Serving Suggestions: Enjoy these brownies as-is, or pair them with a scoop of vanilla ice cream for an extra indulgent dessert.
- Storage: Store leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for 5 days.

Helpful Notes
- Extra Moistness: Overripe bananas are key to achieving the best flavor and texture. The riper, the better!
- Nut-Free Option: Skip the nuts if you prefer a nut-free version or add chocolate chips instead.
- Glaze Variations: For a caramel twist, substitute the glaze with a caramel drizzle.
- Cooling Tip: Ensure the brownies are completely cool before glazing to prevent the glaze from melting into the brownies.
- Pan Size: For thicker brownies, bake in an 8x8-inch pan, but adjust the baking time to 35–40 minutes.
Frequently Asked Questions
- Can I use salted butter instead of unsalted?
Yes, but reduce the added salt to ¼ teaspoon to balance the flavors. - What if I don’t have a 9x13-inch pan?
You can use an 8x8-inch pan for thicker brownies or two 8x4-inch loaf pans. Adjust the baking time accordingly. - Can I add chocolate chips?
Absolutely! Fold in ½ cup chocolate chips for an extra layer of sweetness. - Can I skip the glaze?
Yes, the brownies are delicious on their own, but the glaze adds a rich, buttery finish that enhances the flavor. - How do I know when the brownies are done?
A toothpick inserted into the center should come out clean or with just a few moist crumbs. Avoid overbaking to keep them soft and moist.
