- 1/2 cup (115g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup (60g) all-purpose flour
- 1/3 cup (40g) unsweetened cocoa powder
- 1/2 teaspoon baking powder

Step-by-Step Instructions
Follow these easy steps to bake Banana Walnut Brownies that everyone will love:
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Prepare a 9×9-inch square baking pan by lining it with parchment paper or greasing it lightly with butter or non-stick spray. This ensures that the brownies won’t stick to the pan and will be easy to remove once they’re baked.
Step 2: Mash the Bananas
Peel the two ripe bananas and place them in a large mixing bowl. Use a fork or a potato masher to mash the bananas until they are smooth and there are no large chunks remaining. The bananas should be soft and easy to mash if they are ripe enough.
Step 3: Mix Wet Ingredients
In the same bowl, add the melted butter, granulated sugar, eggs, and vanilla extract. Stir everything together until it’s well combined. You’ll notice the mixture becomes smooth and glossy as the butter and sugar blend with the mashed bananas.
Step 4: Add the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt. Sifting helps remove any lumps in the dry ingredients and ensures an even distribution of the cocoa powder and baking powder throughout the batter.
Gradually add the dry ingredients to the wet ingredients, stirring gently with a spatula or whisk until everything is just combined. Be careful not to overmix the batter, as this can result in dense brownies.
Step 5: Fold in the Walnuts and Chocolate Chips (Optional)
Once the batter is well combined, fold in the chopped walnuts and chocolate chips, if using. The nuts add a wonderful crunch and a nutty flavor that pairs perfectly with the sweet bananas and rich chocolate. The chocolate chips will melt into pockets of gooey chocolate goodness, making every bite a bit more indulgent.
Step 6: Pour the Batter Into the Pan
Transfer the brownie batter into the prepared baking pan and use a spatula to smooth the top into an even layer. The batter will be thick, but it should spread evenly when you smooth it out.
Step 7: Bake the Brownies
Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center of the brownies comes out mostly clean (a few moist crumbs are okay). Be careful not to overbake, as you want the brownies to stay fudgy and moist inside.
Step 8: Let Cool and Slice
Once the brownies are done baking, remove them from the oven and let them cool in the pan for about 10-15 minutes. Afterward, transfer them to a wire rack to cool completely. Once fully cooled, slice into 12-16 squares, depending on your preferred portion size.
Step 9: Serve and Enjoy
Serve these Banana Walnut Brownies with a dollop of whipped cream or a scoop of vanilla ice cream for an extra treat. The combination of warm brownies with cold ice cream is a perfect contrast, adding to the indulgence of this dessert.

How to Serve Banana Walnut Brownies
Banana Walnut Brownies are a versatile dessert that can be served in several different ways to elevate the experience:
- With Ice Cream: A scoop of vanilla, chocolate, or caramel ice cream on top of the brownies is a delightful treat. The contrast of warm brownies with cold ice cream is heavenly.
- With Whipped Cream: Lightly sweetened whipped cream adds a fluffy texture and a cool contrast to the rich brownies.
- With Fresh Bananas: For an extra burst of banana flavor, serve the brownies with freshly sliced bananas on top.
- With Coffee or Tea: These brownies pair wonderfully with a hot cup of coffee or tea, making them a great treat for afternoon tea or a post-dinner snack.
- With a Dusting of Powdered Sugar: If you want to make the brownies look more festive, dust them with a little powdered sugar right before serving. This adds a nice touch of elegance and makes them look bakery-worthy.
Additional Tips for Banana Walnut Brownies
Here are some tips to ensure your Banana Walnut Brownies turn out perfectly:
- Use Overripe Bananas: The riper the bananas, the sweeter and more flavorful they will be. Overripe bananas with brown spots are ideal for baking.
- Don’t Overmix: Be careful not to overmix the batter after adding the dry ingredients. Overmixing can lead to dense and tough brownies.
- Customize with Other Nuts: While walnuts are a classic choice, you can substitute them with other nuts, like pecans or almonds, depending on your preference.
- Add Other Mix-ins: Feel free to experiment by adding other mix-ins, such as dried fruit, coconut flakes, or even swirls of peanut butter for added flavor.
- Check for Doneness: Every oven is different, so start checking for doneness at 30 minutes, and use a toothpick to test the center. If it comes out clean with just a few moist crumbs, your brownies are done.
Freezing and Storing Banana Walnut Brownies
Freezing: Banana Walnut Brownies can be frozen for later enjoyment. To freeze, first let them cool completely. Then, wrap individual brownies in plastic wrap or aluminum foil and store them in a zip-top bag or airtight container. They will keep in the freezer for up to 3 months. To reheat, simply warm them in the microwave for 15-20 seconds or bake them in the oven at 300°F (150°C) for 10 minutes.
Storing: Store any leftover brownies in an airtight container at room temperature for up to 4-5 days. If you live in a particularly warm climate, you may want to store them in the fridge to keep them fresh longer.
