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 banana peanut butter brownies came about. I didn’t intend to make these peanut butter brownies vegan. 

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

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

Rest assured, if you have a brownie craving and don’t have eggs around, you can make these vegan peanut butter banana brownies!

Another reason I love these vegan brownies with banana and peanut butter is because Camryn was helping, and well…she eats the batter as we go along.

I would imagine banana peanut butter brownies with applesauce would be just as good with real eggs in place of the flax eggs. 

Ingredients For Healthy Banana Brownies

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!

I’m sure that these vegan brownies with banana and peanut butter will be your favorite way to use ripe bananas!

How to Make Peanut Butter Banana Brownies

These healthy banana brownies come together very easily. 

  • 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.
  • 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!

  • Next, you’ll 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 into the bottom of the batter too – not just the top, for a more fuller and deeper flavor.

  • Then, bake for 27-32 minutes and let the brownies cool. This is the hard part but if you cut them when they’re too warm and soft, they will crumble easier. 
  • Don’t forget to sprinkle some sea salt on top of these healthy peanut butter brownies!

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

Adaptations for Banana Peanut Butter Brownies

  • I used unsweetened apple sauce for this healthy brownie recipe but you can use a sweetened version to make these sweeter.
  • Want to make this healthy banana brownie recipe sweeter? Add more maple syrup!
  • Not vegan? You can use butter instead of coconut oil and/or honey in place of maple syrup.

How to Store Healthy Homemade Brownies

You have three choices for storing these healthy banana peanut butter brownies.

  • You can either store them at room temperature in a ziplock bag, stasher bag, or airtight container.
  • I recommend storing them in the fridge, as they’ll last longer. They will last 5-7 days.
  • You can also freeze them for later (and add them to your freezer prep before baby!)

These tasty peanut butter banana brownies are in a world of their own. They’re different from my vegan protein bars and pumpkin blondies because they don’t use beans, but all are delicious and healthy snack recipes.
