How to make peanut butter banana brownies?

There is nothing easier than these vegan banana brownies with peanut butter. All you need is a food processor and 5 minutes to create the batter and make the most chocolatey peanut butter banana brownies!

Wet ingredients

This healthy banana brownie recipe is made with simple wholesome ingredients. First, add all the wet ingredient into a food processor and blend until smooth and no more lumps shows.

chocolatey peanut butter banana brownies

You need the wet ingredients below:

  • Ripe bananas – I recommend weighing the peeled banana in grams/oz or cups. Peel your bananas, mash with a fork and place the mashed bananas into a measuring cup or bowl to weight. This ensures the best brownie texture, so be precise. In fact, this recipe is egg-free and bananas act as an egg replacer – you won’t need flax eggs! If you skip the bananas, the brownie batter can be runny and the brownies fragile.
  • Natural peanut butter – it means peanut butter with no additives: no added oil, no added sugar. This is the best option to make healthy vegan peanut butter brownies. Another option is to use almond butter or sunflower seed butter if you have a nut allergy.
  • Coconut oil – you can use refined coconut oil to avoid coconut flavor in your brownie.
  • Vanilla extract

Dry ingredients

Next, stop the food processor, remove the lid, and add in the dry ingredients below.

  • Flour – all-purpose wheat flour or oat flour works well in this recipe. You can use gluten-free all-purpose flour as long as it contains xanthan gum.
  • Unsweetened cocoa powder
  • Baking powder
  • Salt

Finally, close the lid and blend again until a smooth batter forms. If some flour sticks to the side of the food processor bowl, scrape down the sides with a spatula and blend again until well combined.

Add some chocolate chunks or chips!

If you want to enhance the chocolate flavor of your brownies, remove the food processor blade, add vegan chocolate chips and stir with a spatula. Don’t blend the chocolate chips with the food processor blade, this breaks the chips into tiny pieces.

Filling the  brownie pan

Line an 8-inch x 8-inch square baking pan with parchment paper and grease lightly with oil spray or coconut oil. Then, pour the brownie mixture into the pan and spread evenly to cover the pan.

How to make the swirl on the peanut butter brownies?

First, add peanut butter and coconut oil in a small bowl and stir to combine. Then, drop small dollops of the peanut butter mixture all over the pan. Finally use a skewer or knife tip to swirl the peanut butter dollops into the brownie batter.

How to swirl peanut butter in brownies

Place the skewer in the center of the peanut butter dollop and tear from the center to the outside creating a swirling movement at the same time. Repeat for each dollop of peanut butter until the top of the brownies is beautifully covered with peanut butter swirls.

How long to bake brownies?

These simple vegan brownies with banana peanut butter swirl bake within 20-30 minutes at 180C (350F). You know a brownie is cooked through when the top crackle and the batter doesn’t jiggle if you slightly shake the pan.

Cool your vegan brownies down in the pan for 10 minutes, then pull the hanging pieces of parchment paper to release the brownies.

Finally, transfer the brownies onto a cooling rack.

Vegan brownie serving ideas

You can serve these healthy vegan brownies plain or topped with some of the followings dairy-free toppings:

  • Whipped coconut cream 
  • Melted chocolate
  • Raspberries

How to store banana brownies?

Even if this is an egg-free and dairy-free brownie recipe, it’s better to store your banana brownies in the fridge. It stores for up to 5 days in a sealed container or freezes really well. Frozen brownies can be thaw at room temperature the day before, on a plate placed on your kitchen countertop.

Also, brownies get fudgier in the fridge so I highly recommend this option for an extra fudgy texture.
