Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour an 8x8 inch baking pan.
• In a large bowl, whisk together the gluten-free flour, cocoa powder, baking powder, baking soda, and salt.
• In a separate bowl, cream together the sugars and melted butter. Beat in the eggs one at a time, then stir in the vanilla.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Stir in the boiling water until the batter is smooth.
• Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
• Let cool completely before cutting and serving.
