Ingredients
Brownie Ingredients
- 1 cup butter (melted)
- ½ cup cocoa powder
- 1 cup light brown sugar
- 1 cup white sugar
- 4 eggs
- 1 tablespoon vanilla extract
- 2 cups all-purpose flour
- 1⅓ cup brown rice flour
- ½ cup tapioca starch
- ⅓ cup potato starch
Frosting Ingredients
- ¼ cup butter (softened)
- 3 cups powdered sugar
- ¼ cup cocoa powder
- ¼ teaspoon kosher salt
- 5 tablespoons milk
Instructions
- Prepare the Brownie Batter: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper. In a large mixing bowl, whisk together the melted butter, cocoa powder, light brown sugar, and white sugar until well combined. Add the eggs one at a time along with the vanilla extract, whisking until the mixture is smooth and glossy. Gradually add the all-purpose flour, brown rice flour, tapioca starch, and potato starch. Stir gently until the batter is just combined and the flours are fully incorporated.
- Bake the Brownies: Pour the thick brownie batter into the prepared baking pan. Use a spatula to smooth it evenly to the corners. Place the pan in the preheated oven and bake for 22 to 24 minutes. Check doneness by inserting a toothpick in the center; it should come out with moist crumbs but not wet batter.
- Make the Frosting: While the brownies are baking, prepare the frosting. In a separate mixing bowl, combine the softened butter, powdered sugar, cocoa powder, and kosher salt. Use an electric mixer to beat the mixture for 1-2 minutes until it looks like dry crumbs. Slowly add the milk and continue beating for another 1-2 minutes until the frosting becomes smooth, creamy, and spreadable.
- Frost the Brownies: When the brownies come out of the oven, allow them to cool for a few minutes but leave them still warm. Gently spread the frosting evenly over the top of the warm brownies using a spatula or butter knife. Let the frosted brownies cool completely to set before slicing into 18 servings.
Notes
- Ensure the brownies do not overbake; a toothpick should come out with moist crumbs for fudgy brownies.
- You can substitute the milk in the frosting with any plant-based milk for a dairy-free option.
- Use parchment paper in the pan for easier removal and cleaner slices.
- Store brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
- If you prefer denser brownies, use slightly less brown rice flour and tapioca starch.
