BANANA NUT BROWNIES
These delicate brownies are a quick and delicious dessert idea perfect to feed a crowd or anyone with a chocolate addiction. We sometimes call them Banana Bread Brownies because the sweet taste of the bananas reminds us of other favorite baked goods like Traditional Banana Bread and Chocolate Banana Bread.
The warm bars are baked with golden brown walnuts sprinkled on top for a wonderful crunchy texture. You can leave the brownies simple and keep them as a delicious snack to enjoy throughout the day or pack in a lunch box. Another option is making a more decadent dessert with delicious toppings or by serving them with a scoop of Vanilla Ice Cream. Find more topping ideas below.
TOPPINGS
- Melted Chocolate: To make a melted chocolate topping combine 2 tablespoons butter and 2 ounces unsweetened chocolate in a large saucepan. Sift the powdered sugar into a small bowl, then slowly mix it into the chocolate-butter mixture. If it’s too thick you can add a few tablespoons hot water. Pour the melted chocolate glaze over the brownies and let it set before serving.
- Peanut Butter: Make Peanut Butter Topping by combining ½ cup smooth peanut butter, ½ cup heavy whipping cream, 2 tablespoons light corn syrup, and ¼ cup light brown sugar. You can also use almond butter in place of the peanut butter.
- Brown Butter Frosting: To make brown butter frosting combine 6 tablespoons unsalted butter (melted), 3 cups powdered sugar, 1 ½ teaspoons vanilla, and 3-4 tablespoons half and half. Heat butter over medium heat in a saucepan to combine butter frosting.

TIPS FOR MAKING BANANA NUT BROWNIES
- Prep time: Start by preheating your oven to 350 degrees, and prepping your square baking pan with cooking spray or parchment paper. If using baking paper, cut it down to the size of the baking dish.
- Batter: Use a fork to mash two large bananas, and in a microwave-safe small bowl melt the butter. Add the mashed bananas, softened butter, sugar, eggs, and vanilla extract to a large bowl. Whisk the ingredients together until smooth. In a separate bowl sift together the flour, cocoa powder, baking powder, and salt. Add the dry ingredients and whisk until the brownie batter is just combined.
- Baking: Spread the batter into your baking dish and sprinkle the chopped walnuts over the top for some nutty sweetness. Bake the Banana Nut Brownies for 35-40 minutes. You can use a toothpick or butter knife to test if they’re done. If the toothpick comes out clean remove the brownies from the oven. Let the brownies cool slightly before cutting and serving.

VARIATIONS ON BANANA NUT BROWNIES
- Sweeteners: For some different sweeteners, try using brown sugar, coconut sugar, or maple syrup instead of granulated sugar. Maple syrup or brown sugar will give a much darker flavor to the Banana Nut Brownies.
- Oil: Instead of softened butter try coconut oil. Use coconut oil as a 1 for 1 exchange with melted butter.
- Mix-ins: To make Chewy Chocolate Chip Brownies add in some semisweet chocolate, dark chocolate, or white chocolate chips. You can also mix in some peanut butter cups, M&Ms, or roasted nuts for extra mix-ins. Another option is adding in ground coffee beans or an extra teaspoon vanilla for flavor.
- Flour: Instead of using all-purpose flour you can use whole wheat flour, almond flour, or oat flour in the flour mixture for Banana Walnut Brownies.

Delicious, didn’t change a thing! Thanks for the recipe, Sabrina!
I made these brownies on Saturday morning. I did not have any walnuts so I substituted pecans and added about 1/2 – 3/4 cup espresso chips. Did not put a topping on as I did not think it was needed. The brownies were very moist, enjoyed by all and there are none left. I thought this was a wonderful, easy to follow recipe. A great way to use up overly ripe bananas in a form other than banana bread. Thanks for a great recipe that I will use over and over again.
I’m so glad you enjoyed it, Susan.
