  • 2 ½ cups raw walnut halves (10 oz)
  • cup coconut sugar
  • ¼ cup pure maple syrup
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1 tablespoon chia seed
  • cup unsweetened cocoa powder
  • 1 tablespoon coconut flour
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • cup chocolate chips, dairy free if desired
  • 2 tablespoons chopped walnuts
  • For the topping:
  • 2 tablespoons chocolate chips, dairy free if desired
  • 1 teaspoon coconut oil


  1. Preheat oven to 350 degrees F. Place walnut halves on a baking sheet. Toast walnuts in oven for 8-10 minutes or until fragrant and slightly toasted. Allow walnuts to cool on baking sheet for 5 minutes.

  2. After a few minutes place walnuts in bowl of food processor and process until smooth, scraping down the side as necessary. You want the walnuts to become creamy like nut butter.
  3. Once walnuts are creamy (like the picture above), transfer walnut butter to a large bowl and add in coconut sugar, pure maple syrup, eggs and vanilla extract; mix until smooth and well combined. 
  4. Gently stir in the cocoa powder, coconut flour, baking soda and salt until smooth. Fold in chocolate chips and chia seeds.
  5. Pour brownie batter to a 10-inch skillet coated with nonstick cooking spray or to 9x9 inch square baking pan. Sprinkle walnuts on top. Bake for 23-27 minutes or until brownies are done and a tester comes out clean or with just a few crumbs attached.

  6. To make the chocolate drizzle: Add chocolate chips and coconut oil to a small saucepan and place over low heat. Stir until completely smooth and melted. Drizzle all over the brownies. Cut into 16 slices or squares. Enjoy!

Recipe Notes

To make vegan: I think you could easily make this vegan by using a flax egg.

To reduce sugar in the recipe: Leave out chocolate chips from the batter and just use the drizzle -- or leave off both. I promise they'll still be delicious!
