Sabrina’s Banana Nut Brownies Recipe
These delicate brownies are a quick and delicious dessert idea perfect to feed a crowd or anyone with a chocolate addiction. I sometimes call them Banana Bread Brownies because the sweet taste of the bananas reminds me of other favorite baked goods like Traditional Banana Bread and Chocolate Banana Bread.

Sabrina’s Tips
Prep your square baking pan with cooking spray or parchment paper. If using baking paper, cut it down to the size of the baking dish. 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.

About this Recipe
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.
How to Store
- Serve: You can keep the brownies at room temperature for 3-4 days. Let the brownies cool then cover and keep them in the pantry.
- Store: To keep Banana Brownies in the fridge, cover them in plastic wrap or put them in an airtight container. They’ll stay good for up to 1 week.
- Freeze: After giving the brownies some cooling time, you can cut them into squares and put them in an airtight container or freezer bag. They’ll keep well frozen for up to 6 months.
Ideas to Serve
Chocolate Topping
- 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 Topping
- 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.
Variations
- 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.

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.
