One-Bowl Healthy Vegan Brownies with a homemade Peanut Butter Frosting for an easy and delicious gluten-free and refined sugar-free brownie recipe!

  • Prep Time: 5 mins
  • Cook Time: 25 mins
  • Total Time: 30 minutes

Yield: 9 brownies 1x




  • 2 cups gluten-free oat flour (sub spelt or gluten-free all purpose if needed)
  • 1/2 cup cacao powder
  • 1 cup coconut sugar
  • 2 teaspoons baking powder
  • 1/3 cup liquid coconut oil
  • 1 cup non-dairy milk (almond, coconut, oat)
  • 1 teaspoon vanilla extract
  • 1/3 cup dark chocolate chips, melted

Peanut Butter Frosting:

  • 1 14-ounce can full-fat coconut milk
  • 4 tablespoons creamy peanut butter (you can also add additional powdered PB if you have for flavor!)
  • 3/4 cup tapioca flour (or sub arrowroot flour! I do not recommend any others as you need a thickening flour!)
  • 4 tablespoons Wedderspoon Manuka Honey


  1. Preheat oven to 350 degrees and grease an 8×8 baking dish with coconut oil or line with parchment paper
  2. In a large bowl, mix together the flour, cacao powder, coconut sugar and baking powder until evenly combined
  3. Add in the coconut oil, milk, vanilla extract and mix again to combine
  4. Mix in the melted dark chocolate so the batter gets even more rich and chocolatey
  5. Pour batter into baking dish and evenly spread then bake in oven for 22-25 minutes (or until toothpick turns out clean)
  6. While the brownies bake, make the frosting! Shake the coconut milk can and pour 1/2 of it into a medium bowl (save the other half for smoothies, oatmeal, anything!)
  7. Add in the creamy peanut butter and stir well
  8. Add in the flour and honey and stir well so a thicker frosting-like consistency is formed
  9. Once brownies are done and cooled a bit, spread the frosting on top and enjoy
