Ingredients :
- 2 ripe bananas
- 1 large egg
- 100 g cocoa powder
- 1 teaspoon espresso powder
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 tablespoon vanilla extract
- 225 g unsalted butter
- 350 g granulated sugar
- 300 g dark chocolate (roughly chopped)
- 180 g all-purpose flour
- 100 g natural peanut butter
Directions :
- Prep: Preheat oven to 350ยฐF. Line a 9×9" square pan with parchment paper on the bottom and all sides. Set aside.
- Mash bananas: In a large mixing bowl, add ripe bananas and mash with the back of a fork. Add the egg and whisk until combined.
- Add dry ingredients: Add in cocoa powder, espresso powder, baking powder, salt, and vanilla extract. Whisk again until thoroughly combined. Set aside.
- Melt butter & chocolate: In a small saucepan on low-medium heat, melt butter, sugar, and dark chocolate. Stir until most of the sugar has dissolved and the mixture is hot and glossy.
- Whisk in warm mixture: Slowly stream the warm chocolate mixture into the bowl of the banana mixture while whisking constantly with your other hand. Keep whisking until combined.
- Add flour: Finally, add the flour and whisk until just combined and no large flour patches remain.
- Fill pan: Pour the brownie batter into your lined pan. Use an offset spatula to spread the batter into the corners and edges.
- Swirl peanut butter: Transfer the peanut butter to a piping bag or ziploc bag. If the peanut butter is too stiff, warm it in the microwave for 10-15 seconds before using. Cut the tip off the bag and pipe it across the top of the brownie batter in large squiggle. Use a chopstick to swirl the peanut butter and brownie batter together in circular motions until you like how it looks.
- Bake: Bake for 25-28 minutes or until the edges are set but the center is still soft and moist.
- Chill brownies: Immediately sprinkle the top with flaky salt and transfer the pan and the wire rack to the fridge to stop the cooking process. Chill the brownies for at least 3 hours or until completely cool. The middle will get fudgier as it cools.
- Slice: Once chilled, release the brownie from of the pan by lifting it by the parchment paper overhangs. Cut the brownies into 9 squares. Serve at room temperature or heat up individual slices.
how to serve Banana Peanut Butter Brownies
Serve these at room temp or slightly warm. They go well with milk, coffee, or plain cream. For a fancier plate, add a spoon of whip cream or a scoop of vanilla ice cream. You can also serve with a small slice of a soft roll like this: chocolate peanut butter swiss roll.
how to store Banana Peanut Butter Brownies
Cool the brownies fully before you store them. Wrap the whole block in plastic or put it in an airtight box. Store in the fridge for up to 5 days. For longer storage, freeze single squares in a box with parchment between layers for up to 2 months.
tips to make Banana Peanut Butter Brownies
- Use ripe bananas for best sweet taste and soft texture.
- Do not overmix after adding flour. Mix just until the flour looks wet.
- Warm the peanut butter a bit if it is too thick so it pipes well.
- Chill the brownies well to let them set and get fudgy in the middle.
- For a cleaner cut, warm the knife under hot water and dry it before each cut.

variation (if any)
- Add chopped nuts on top before baking for crunch.
- Use milk chocolate for a softer sweet taste.
- Swap peanut butter for almond butter for a nutty change.
- Fold in chocolate chips to make the center more gooey.
FAQs
Q: Can I skip the banana?
A: You can, but the banana adds moisture and a mild taste. If you skip it, add a bit more egg or oil.
Q: Can I use crunchy peanut butter?
A: Yes. Crunchy peanut butter gives a nice bite. Warm it first if it is thick.
Q: How do I know when the brownies are done?
A: The edge will set and the center will still look a bit soft. After cooling, the center firms but stays fudgy.
Q: Can I use less sugar?
A: You can lower sugar a little, but the texture will change. The chocolate and banana help keep them sweet.
Q: Can I halve the recipe?
A: Yes. Use a smaller pan and watch the bake time. A thin pan will bake faster.
