These healthy peanut butter brownies have come in handy in multiple instances. One of my biggest pet peeves is when I really want something (like dark chocolate brownies) but I lack some key ingredients – ahem, eggs. 

When this happens, I adapt and that’s how these healthy banana brownies came about. I didn’t intend to make these peanut butter brownies vegan, but back to the egg situation.

If we’re making peanut butter banana brownies (or anything with peanut butter for that matter), count Camryn in. 

So, banana and peanut butter brownies are a healthyish treat that came about out of luck, and now we rely on week to week.

I played around with a few versions and I’m thrilled with how gooey, soft, chocolatey, and peanut-buttery these vegan peanut butter brownies came out.

Another reason I love this healthy banana brownie recipe is because Camryn was helping, and well…she eats the batter as we go along.

Banana Peanut Butter Brownies Ingredients

As I mention in nearly every recipe, I order many of these food pantry items from Thrive Market, so I always have my pantry stocked.

These staples come in handy and here’s what you need for peanut butter banana brownies.

A few notes:

  • The riper your bananas, the more natural sweetness.
  • If you’re not vegan, you can use butter in place of coconut oil and eggs in place of flax eggs
  • Almond butter, cashew butter or any nut butter replacement works too!

I’m sure that these healthy banana chocolate brownies will become your favorite way to use ripe bananas. I know we all have them and then blank on how to use them.

Well, ripe bananas are now prime real eastate for banana chocoalte peanut butter brownies.

We use bananas a lot, and pretty much always have some riper bananas on hand. This could be because sometimes I have to make 2-3 trips to the grocery store a week, and each time, I get more bananas.

How to Make Healthy Banana Brownies

These healthy banana brownies come together very easily, which is what you want in a healthy banana brownie recipe.

First, you have to make your flax egg, which is a vegan alternative to using real eggs. Just mix 1 Tbsp of ground flax seed with 2.5 Tbsp of water, and let it gel. We’re using two flax eggs, so I doubled that recipe.

Next, mash your bananas in a bowl with a fork. Using ripe bananas will make these more naturally sweet, and easier to mash.

Then, add your coconut oil, applesauce, maple syrup, vanilla, flour, and baking powder to the bowl.

Finally, mix in your cocoa powder and flax eggs to the mixture and you’re almost ready to pop these eggless peanut butter brownies in the oven!

Pour the batter into a 9×9 baking pan and swirl in the peanut butter with a knife.

I like to make sure the peanut butter mixes well into the bottom of the batter too, not just the top. This gives a fuller and deeper flavor to these easy banana brownies.

Then, bake for 27-32 minutes, and let these healthy banana brownies cool. This is the hard part but if you cut them when they’re too warm and soft, they will crumble easier!

I like to sprinkle some sea salt on top as they’re cooling to help bring out more flavor. You really can’t go wrong with peanut butter, banana and peanut butter.

I really love to pair them with my peanut butter coffee smoothie for breakfast when I’m in an extra chocolatey mood. 

Ingredient Substitutions

  • I used unsweetened apple sauce for this healthy banana brownie recipe but you can use a sweetened version to make these sweeter.
  • Not vegan? You can use butter instead of coconut oil and/or honey in place of maple syrup.
  • Use any nut or seed butter in place of the peanut butter.
  • To make these banana and peanut butter brownies sweeter, add more maple syrup or honey.
