Oat flour brownies are simple to make in one bowl and made with better-for-you ingredients! They’re fudgey, rich, and naturally gluten free!

I’m always looking for new ways to eat brownies. It’s like I’m on a mission to find the make (and eat) the best brownies and I come back here to report all my findings.

As soon as oat flour became a staple in my pantry, I knew I needed to try it in some brownies. Oat flour is so mellow, slightly sweet, and adds a really great fluffiness to any dessert.

These are intensely fudgey, rich, and decadent. We loved them exactly as is, but to be honest, I can’t stop thinking about adding a scoop of ice cream on top of a plate of warm brownies. Luckily I still have some of these oat flour brownies leftover so this may be happening real soon.

Ingredients for oat flour brownies:

  • chocolate chips: I use semi-sweet chocolate chips but you can definitely use milk chocolate or dark chocolate depending what you like.
  • coconut sugar: you can sub in a different granular sweetener if you prefer.
  • agave nectar: honey or maple syrup is a good sub here
  • eggs: just two plus a yolk for some extra fudginess
  • vanilla extract: a splash
  • oat flour: this is going to give the brownies some structure!
  • cocoa powder: for some extra, deep rich chocolate flavor
  • salt: gives some salty balance to the sweet and brings out the extra choco flavor

How to make homemade oat flour:

It’s so easy! All you need to do it put your old fashioned rolled oats in a food processor or blender and blend for about 1 minute until completely chopped up. I like to do this is small batches to make sure they all get chopped evenly.

How to make these easy, fudgey oat flour brownies:

Melt the chocolate chips. I melted these in the microwave, stirring every 30 seconds to make sure the chocolate didn’t burn.

Mix in the wet ingredients. Once the chocolate is smooth and melted, whisk in the coconut sugar, agave, eggs and yolk, and vanilla.

Combine the dry ingredients. Add in the oat flour, cocoa, and salt. Mix again until combined.

Spread and bake. Transfer the batter to an 8×8 square pan and bake.

Cool in pan. I find it’s best to allow these brownies to cool in the pan before you pull up the parchment paper and cut into them.

How to store these brownies:

Brownies can be kept out at room temperature in an air tight container for about three days. They get super fudgey and delicious in the fridge, you can also store them in an air tight container in the fridge for about a week.
