Fudgy Vegan Banana Brownies. The fudge-iest brownies made with melted chocolate, coconut oil, brown sugar, bananas, vanilla, homemade oat flour (old fashioned oats ground in food processor), cocoa powder, salt, and chocolate chunks! Slightly healthier, definitely delicious, and gluten free!

If you love vegan treats, you’ll also love: healthy double chocolate almond butter cookies, vegan raspberry oatmeal bars, and vegan scotcheroos. 

Holy. Fudge. These are good. These are fudgy vegan banana brownies and they are out.of.this.world.goooooooood.

Vegan? Yes. Health food. Not exactly. 😉 But I did significantly reduce the sugar by using less refined sugar and added banana for sweetness AND they’re made with oats instead of all-purpose flour. So I mean. They’re definitely healthy…er. 🙂

Regardless. These are so so sooooo good and I’m not gonna lie, Trevor and I devoured a batch in under 3 days. #noshame

What I love most about this recipe is that there’s no eggs and no flour – both of which you’re technically not supposed to eat raw – which means – you can . . .

  1. Eat the raw batter safely! WOOOO.
  2. Under bake these! Heck yes for best fudgy brownies ever.

I’m obviously very excited about these fudgy vegan banana brownies and I just know you will be too.

Ingredients in fudgy vegan banana brownies

  • Semi-sweet chocolate – I used Baker’s Semisweet Baking Chocolate Bar, but verify that your brand is vegan if necessary
  • Coconut oil
  • Brown sugar
  • Bananas
  • Vanilla extract
  • Oat flour – I use homemade!
  • Cocoa powder
  • Salt

How to make the best fudgy vegan banana brownies

  1. Preheat the oven to 350°F and grease an 8″ square nonstick baking dish with cooking spray then line it with parchment paper. I like cutting the paper long so it hangs over the side, making it easy to lift the brownies out of the pan.
  2. Chop 1 (4 oz) chocolate bar into chunks and place into a microwave safe bowl. Microwave in 30 second intervals, stirring in between, until melted.
  3. Meanwhile, chop the other 4 oz chocolate bar into chunks and set aside. You’ll be stirring these into the batter later.
  4. To the melted chocolate, add in melted coconut oil, brown sugar, bananas, and vanilla.
  5. Whisk until well combined.
  6. Add in oat flour, cocoa powder, and salt.
  7. Use a rubber spatula to gently fold the mixture together.
  8. Fold in the chocolate chunks.
  9. Pour batter into prepared baking pan.
  10. Bake in preheated oven for about 30 minutes, more or less depending on how fudgy you like your brownies. They should look set, but it’s ok if an inserted toothpick comes out with a little batter on it.
  11. Remove from oven and cool completely before cutting. These need to cool completely or they’ll fall apart.
  12. You can then rewarm these to serve warm (with ice cream please!) or serve them at room temperature or even chilled!

How to make homemade oat flour

To replace the flour we’re grinding up old fashioned oats in our food processor. That’s it. Simply place old fashioned oats into the food processor and pulse until it resembles a fine flour. It’s super simple, super quick, and you can grind up more than you need and just store the extra in your pantry for later!

These brownies are insanely fudgy, so moist, a little banana-y, and just overall so delicious!

I love that you can eat the batter raw and bonus they’re gluten free and SO quick and easy, too!

    5 stars Absolutely Loved this recipe!!!! I drizzled some melted chocolate chips instead of the bar over them once they’d cooled and added 2 tbsp of milk to my wet ingredients! Definitely making more! These were so great!

    5 stars The recipe came out so good. I did few tweaks. Replaced oats flour with multigrain wheat flour, reduced the oil to 1/4 cup and replaced chocolate with butterscotch.Thanks so much for this wonderful recipe.

    5 stars Hmm, can I replace the chocolate with white chocolate and omit the cocoa powder to make white chocolate blondies? 🤔🤔 Been looking for such a recipe using less sugar, with oat flour without butter but they either don’t use white chocolate or use something like 2 cups + of sugar 😅😅😅 Since this recipe was such a success, was thinking if its okay to switch with white chocolate 🤔🤔😂

      You could try! You’d need to replace the cocoa powder with more oat flour. 🙂

      5 stars I mad it and it was so good! A little crumbly and oily at the bottom but taste good! I baked a few minutes longer than 30 mins cause the batter felt watery at 25 ish mins. I use 50g brown sugar and 2 tbsp+ maple syrup(or it might be maple flavoured syrup, the bottle was repacked by the baking supply store 😅😅). I actually think it was a little too sweet, chocolaty and fudgy hahaha. Next time, I’m going to reduce the brown sugar a bit, replace 1/4 cup of choc chunks with raisins and add 1/4 tbsp of chia seeds to see it it will hold its structure a teeny bit more. Next try I want to add a bit more flour haha. Not sure if it will need baking powder or not if I add more flour 🤔🤔 Ah well, the experimentation continues!

    • Jennifer @ Show Me the Yummy

      So glad you liked these! 🙂 The recipe doesn’t call for maple syrup, so that’s probably why your texture was different!

    5 stars These came out SO Nice! Used 60% dark chocolate and I added 1/2tsp baking powder bc I was nervous about there being no raising agent, and I left them in for almost the full 30mins, and they’re the perfect texture! Will definitely make again!

    5 stars These were the best brownies I’ve ever had (including non-gluten or dairy-free). I actually like very dark chocolate, so I put slightly more pure cocoa powder than the recipe called for, a little less sugar, and used 72% cocoa chocolate. I also melted the chocolate slowly in a pan with the coconut oil instead of in the microwave. The brownies come apart a little bit when warm but they stay together pretty well when cool, and they are still delicious when frozen… I followed the recommendation to eat them warm with ice cream (I used soy-based vegan cherry ice-cream), yum!!!

    5 stars These came out fantastic! I’m not completely vegan, but like to bake gluten free. I followed the recipe exactly plus added 1 egg and chopped walnuts. Thank you, this recipe is a keeper especially when I have ripe bananas to use up!

    5 stars Thank you so much! Every time I have tried to go vegan in the past, I am always torn away by sweet treats. Especially brownies and cheesecake. This recipe is My new obsession! So simple, so clean, and so delicious! I’m absolutely in love and my teenagers cannot even tell a difference. Stay amazing and have a beautiful day!
