These rich, moist banana bread brownies transform overripe bananas into an irresistible treat that combines classic banana bread flavors with the dense, chewy texture of a perfect brownie. A crown of browned butter frosting adds a sophisticated touch that elevates this homestyle dessert into something truly special.

After making these countless times for family gatherings, I've found that letting the brownies cool completely before frosting creates the best texture. My grandchildren always fight over the corner pieces, which develop a slightly crispy edge that contrasts beautifully with the moist interior.

Essential Ingredients Guide

  • Ripe bananas: Choose deeply speckled bananas for maximum natural sweetness and strongest banana flavor. The mushier, the better
  • White whole wheat flour: Offers a lighter texture than regular whole wheat while maintaining nutritional benefits. Look for King Arthur brand for consistent results
  • Unsalted butter: Using unsalted allows precise control over saltiness. European-style butters brown particularly well due to their higher fat content
  • Local honey: Raw honey adds complex sweetness and helps keep the brownies moist. Dark amber varieties complement the banana flavor beautifully

Creating Your Brownies

Preparing the Base:
Carefully toast walnuts until fragrant and golden, setting the foundation for deep, nutty flavor throughout.
Browning the Butter:
Watch for butter to turn amber and release a nutty aroma, about 5-7 minutes of gentle bubbling.
Mixing the Batter:
Combine wet ingredients until smooth, then fold in dry ingredients just until no flour streaks remain.
Adding the Nuts:
Gently incorporate toasted walnuts, ensuring even distribution without overmixing.
Final Baking:
Look for edges to pull away slightly from the pan and center to spring back when touched.

My family particularly loves the browned butter element in this recipe. When my daughter was young, she would always request these brownies for her birthday instead of cake, saying the nutty butter aroma reminded her of weekend mornings in our kitchen.

Complement Your Creation

These brownies shine alongside a scoop of vanilla bean ice cream or a warm cup of spiced chai tea. For breakfast, serve slightly warmed with a dollop of Greek yogurt and a drizzle of honey.

Sweet Adaptations

Transform these brownies by adding dark chocolate chunks, swirling in peanut butter before baking, or incorporating toasted coconut for tropical flair. For gluten-sensitive guests, a high-quality 1:1 gluten-free flour blend works beautifully.

Keeping It Fresh

Store these treasures in a glass container with a tight-fitting lid, placing wax paper between layers to prevent sticking. They'll stay perfectly moist for four days at room temperature or up to three months in the freezer.

03 1 cup mashed ripe banana (about 3 medium)
04 ⅔ cup honey
05 ⅓ cup light or dark brown sugar
06 1 large egg
07 2 teaspoons pure vanilla extract
08 ¾ cup all-purpose flour
09 ¾ cup white whole wheat flour
10 ½ teaspoon ground cinnamon
11 1 teaspoon baking powder
12 ¼ teaspoon baking soda
13 ¼ teaspoon kosher salt

→ Brown Butter Frosting

14 6 tablespoons unsalted butter
15 1 ½ cups powdered sugar
16 1 teaspoon pure vanilla extract
17 1 to 2 tablespoons heavy cream (or half-and-half or milk of choice)

Instructions

Step 01

Heat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper, creating handles on opposite sides, and coat with nonstick spray. Toast walnuts on a rimmed baking sheet for 8-10 minutes until fragrant, tossing once. Chop roughly when done.

Step 02

Mash bananas in a large bowl. Brown butter in a light-colored saucepan over medium-low until pecan-colored and nutty-smelling, about 3-5 minutes. Pour immediately over mashed bananas. Add honey and brown sugar, whisk until smooth. Once cooled to lukewarm, whisk in egg and vanilla.

Step 03

Combine all dry ingredients in a separate bowl. Fold gently into banana mixture just until flour disappears. Fold in walnuts. Spread in prepared pan and bake 22-25 minutes until edges are lightly browned and toothpick comes out clean.

Step 04

Brown butter again in the same pan. Remove from heat and gradually stir in powdered sugar. Add cream as needed for spreadable consistency, then stir in vanilla. Frost completely cooled brownies before slicing.
