Fudgy Banana Brownies

If you are a big fan of bananas (me, me!), then today’s recipe is just for you.

I have taken my favourite brownie recipe and stuffed them full of bananas, which makes for a SUPER fudgy and moist brownie.

You’re seriously gonna love them! 

These Fudgy Banana Brownies are loaded with 4 large bananas. Two mashed bananas go into the batter, and two whole bananas, cut in half, are placed on top of the batter.

Mmmm.

Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these brownies. You can find my recipe card at the bottom of this post for the complete list with their amounts.

  • unsalted butter
  • granulated sugar
  • cocoa powder
  • salt
  • large eggs
  • vanilla extract
  • large bananas (you’ll need 4)
  • plain/all-purpose flour
  • chocolate chips

How to make Fudgy Banana Brownies

To make these brownies, add the butter, sugar, cocoa powder, and salt to a microwave-safe bowl, and heat in 30 second intervals, stirring after each one, until the butter is melted and the mixture feels very warm to the touch.

Add the eggs, vanilla, and TWO mashed bananas, and mix until combined. Fold in the flour, then the chocolate chips.

Pour the batter into an 8×8-inch square baking pan lined with parchment or foil, and spread out evenly.

Slice the remaining bananas in half lengthwise, and place on top of the batter.

Bake for 45 – 50 minutes, or until the centre is no longer jiggly and a toothpick inserted comes out almost clean with a few moist crumbs. 

Allow to cool completely before cutting into bars.

Because these brownies are incredibly moist and fudgy, I like to keep mine refrigerated and serve them chilled.

The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.

Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

These Fudgy Banana Brownies are:

  • SUPER thick, fudgy and moist
  • so quick and easy to throw together
  • rich and chocolatey
  • loaded with banana flavour

How long will these brownies last? These brownies will stay fresh, stored in an airtight container, at room temperature or in the fridge for up to 1 week.

Can I freeze these brownies? Yes, they also freeze well for up to 3 months. Thaw overnight in the fridge before serving.

Fudgy Banana Brownies

Yield: 16 brownies
Prep Time: 20 minutes
Cook Time: 45 minutes
Total Time: 1 hour 5 minutes

These brownies are incredibly thick, fudgy, and loaded with banana flavour. Banana lovers will LOVE these!

Ingredients

  • 1 and 1/4 sticks (140g) unsalted butter
  • 1 and 1/2 cups (300g) granulated sugar
  • 3/4 cup (75g) cocoa powder
  • 1/4 teaspoon salt
  • 2 large eggs, cold
  • 2 teaspoons vanilla extract
  • 4 large bananas
  • 1/2 cup (60g) plain/all-purpose flour
  • 1/2 cup (90g) chocolate chips

Instructions

  1. Preheat the oven to 180C/350F/Gas 4. Line an 8x8-inch square baking pan with foil or parchment paper, and set aside.
  2. Place the butter, sugar, cocoa powder, and salt into a microwave-safe bowl, and microwave in 30 second intervals, stirring after each one, until the butter is melted and the mixture feels very warm to the touch.
  3. Mix in the eggs, one at a time, then the vanilla and TWO mashed bananas. Fold in the flour until fully combined. Fold in the chocolate chips.
  4. Pour the batter into the prepared pan and spread out evenly. Slice the remaining bananas in half lengthwise, and place on top of the batter.
  5. Bake for 45 - 50 minutes, or until the centre is no longer jiggly and a toothpick inserted comes out almost clean with a few moist crumbs. You may cover the pan loosely with foil past the 30 - 40 minute mark to prevent excessive browning.
  6. Allow to cool completely in the pan on a wire rack before cutting into bars. I refrigerated my brownies before slicing for extra neat, clean cuts.

Notes

These brownies are best served chilled as they are very moist.

Brownies stay fresh, stored in an airtight container, in the fridge for up to 1 week. They also freeze well for up to 3 months. Thaw overnight in the fridge before serving.

I’ve made these several times now and they’re STUPID good. Listen, you need to try them with vanilla ice cream and a tablespoon of bourbon poured over the whole thing. It’s an amazing combination, I’ve served it at a fancy dinner party and everyone LOVED it

These are very delicious but very sweet! When I make them again (and I will, because yum!) I will make them with half the sugar and perhaps ground oats instead of flower for increased healthiness. I subbed the chocolate chips for walnuts here btw. Thanks for the recipe!

These are SO GOOD. And quick to come together. We couldn't wait for it to completely cool though :)

I made this but with some small tweaks based on the comments below. I also split the recipe in half to make a chocolate and white chocolate version (omitted the cocoa in this one), added a little more flour, halved the sugar and used brown sugar. I layered the mixes - white chocolate brownie, banana slices then I poured over the chocolate layer and baked for 40 minutes. The bottom white choc layer wasn’t quite cooked but I think my banana layer was partly to blame, still tastes good and banana/white choc tastes just like bananas in syrup.

Thankyou. And could l use oil instead of butter? Out of butter.
