Ingredients

• 1 cup cocoa powder

• 2 cups all-purpose gluten free flour mix (6 parts SUPERFINE brown rice flour, 2 parts potato starch, 1 part tapioca flour)

• 1 cup sour cream

Preparation

  1. Preheat oven to 350°F. and butter and dust with cocoa powder a 3-quart Bundt pan, knocking out excess powder.

  2. In a medium sized bowl whisk together cocoa, flour, salt, and baking soda.

  3. In a large bowl beat together butter and sugar until light and fluffy. Add eggs, 1 at a time, beating well after each addition, and beat in sour cream and vanilla until combined well. With mixer on low speed gradually beat in flour mixture until just combined. Slowly and gently stir in chocolate chips.

  4. Pour batter into prepared Bundt pan, spreading evenly. Bake cake in middle of oven 1 hour and 20 minutes, or until a tester comes out clean.
