Banana Brownies

Chewy, fudgy, super moist banana brownies have a delicious chocolate flavor and hint of banana. Made with simple, everyday ingredients – they’re the perfect way to use up your brown bananas AND get your chocolate fix. 

These fudgy banana brownies are a combination of classic banana bread and homemade brownies. You end up with a brownie that’s incredibly moist. They have a hint of cocoa, the mild banana flavor that you love from banana desserts, and tons of chocolate chips.

Banana Bread Brownie Recipe

For this recipe, we’re basically taking a classic brownie recipe and adding in 1 cup of mashed bananas. For ingredients you’ll need:

• 1 cup unsalted butter
• 2 cups white sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1 cup mashed bananas – about 3 brown bananas
• ¾ cup cocoa powder
• 1 ¼ cup all-purpose flour
• ½ teaspoon salt
• 1 ¾ cups chocolate chips.

You’ll notice that there are only 2 eggs in this recipe (even though we’re making a VERY big batch of brownies). Because the mashed bananas add so much moisture to the recipe, we have to reduce the number of eggs so that the brownies don’t get soggy.

I also often use more cocoa powder than flour in brownies or at least equal parts. However, in this recipe, we’re using more flour than cocoa powder because I wanted to ensure that you could still taste the banana. 

Baking Banana Brownies

Because these brownies are extremely moist – it can be a little tricky to know when they’re done. They’ll bake for about 35 minutes and when they’re done an inserted toothpick will come out clean or with a few damp crumbs. Note that oven times will very, and the longer you bake the brownies the moister they will be.

Make-Ahead and Storage Instructions

• Always wait until brownies are completely cooled before slicing. At least 4 hours. This gives cleaner cuts and helps the brownies firm up so that they aren’t just total goo.
• Store brownies in an airtight container in the fridge for up to 5 days. Because these brownies are so moist, they should definitely be stored in the fridge.
• Brownies can be frozen for up to 3 months in an airtight container. Then thaw in the fridge.
