The Best Chewy Oat Flour Brownies

12 servings
These oat flour brownies are rich, fudgy, and packed with chocolate chips! They're everything a good brownie should be, with a shiny top, chewy edges, and a soft center.
I love how easy they are to make in just one bowl!

Ingredients

  • 10 tablespoons (141g) butter melted
  • ½ cup (85g) chocolate chips
  • 1 cup (200g) granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon kosher salt
  • 3/4 cup (68g) oat flour
  • 1/4 cup (21g) cocoa powder
  • 1 cup (170g) chocolate chips

Instructions

  • Preheat the oven to 350°F. Grease a 9×9 metal pan with cooking spray and set aside. (I like this light metal pan.)
  • Cut the butter into tablespoon-sized pieces. Add the butter and 1/2 cup of chocolate chips to a large microwave-safe bowl. Microwave for 30 seconds. Stir well, microwave for another 15 seconds and then stir well again. Repeat for 15 seconds until the chocolate and butter are completely melted and well-combined.
  • Add the granulated sugar and whisk for 30 seconds. Stir in the eggs one at a time, whisking 20 seconds after each addition. Whisk in the vanilla extract and salt.
  • Using a rubber spatula, mix in the cocoa powder and oat flour until fully combined. Stir in the remaining chocolate chips.
  • Pour the batter into the prepared baking pan. Smooth into an even layer. Bake for 30-35 minutes until set and a toothpick inserted into the center of the brownies comes out clean.
  • Cool the brownies for 30 minutes before cutting. Slice and enjoy!

Notes

Gluten-Free: Make sure you use certified gluten-free oat flour or make homemade oat flour with certified gluten-free oats. Oats are naturally gluten-free, but have a high risk of cross-contamination from the manufacturing process.
Dairy-Free: I don't recommend making these brownies dairy-free.
To Make-Ahead: The batter needs to be baked immediately after prepping, but the baked brownies store well for a great make-ahead dessert!
To Store: Store the brownies in an airtight container at room temperature for up to 5 days.
To Freeze: Wrap tightly or store in an airtight container. Freeze for up to 3 months. Thaw at room temperature for 1-2 hours.
