Reese's Brownies {Gluten-free}

Total Time

Chewy Brownies with intense chocolate and peanut butter flavor.


  • 1 cup butter, melted (2 sticks)
  • 3 cups sugar
  • 1 Tbsp. pure vanilla extract
  • 4 eggs
  • 1 1/2 cups gluten-free all-purpose flour*
  • 3/4 tsp. xanthan gum
  • 1 cup cocoa powder
  • 1 tsp. salt
  • 1 1/2 cups chopped peanut butter cups
  • 1/2 cup Reese's peanut butter baking chips


  1. Preheat oven to 350°. Lightly grease a 9x13 baking dish. I prefer using a glass one.
  2. In a mixing bowl, combine the melted butter, sugar, and vanilla. Beat in the eggs, one at a time, mixing well after eat, until thoroughly blended.
  3. In a separate bowl, whisk together the flour, xanthan gum, cocoa powder, and salt. Gradually stir the flour mixture into the butter mixture in the mixing bowl until blended. Stir in the chopped peanut butter cups and the Reese's peanut butter chips. Spread the batter evenly into the prepared baking dish.
  4. Bake in a preheated oven at 350° for about 35-40 minutes, or until a toothpick inserted near the center comes out clean or with crumbs only, no batter.
  5. Remove from oven, and cool pan on a wire rack before cutting.
  6. Notes
  7. *I've tested this withGluten Free Mama's Almond Flour Blend and gfJules flour and recommend either!
  8. If using a flour blend that already includes xanthan or guar gum, then omit the xanthan called for in the recipe.


Recipe Notes

If using a gluten-free flour that has xanthan gum already in it, then omit the xanthan gum listed in this recipe.
I recommend gfJules and Gluten Free Mama's all-purpose flour blends for best results.
