This recipe was given to me from some magazine (I changed the recipe a lot when I made it, though).
Chocolate Peanut Butter Brownies (Gluten-free, Dairy-free, Corn-free)
1 cup oil
1 cup cocoa (I used 3/4 cup dark cocoa)
1 1/3 cup GF flour (I used rice)
1 teaspoon guar gum
1 teaspoon baking soda
1 teaspoon cream of tartar
1 teaspoon salt
1/2 cup peanut butter
Preheat oven to 350F. Grease an 9x13" baking pan. Dust with rice flour.
Beat together oil, cocoa, sugar, eggs and vanilla. Stir in flour, guar gum, baking soda, cream of tartar and salt until well combined.
Pour batter into prepared pan. Dollop peanut butter onto top of batter. Gently swirl peanut butter into batter with a knife or spatula. Bake 25 minutes, or until a knife inserted into the middle of the pan comes out clean. If batter remains on knife, continue baking in 3 minute increments until done. Let cool completely before slicing into squares.
