Gluten-Free Brownies Recipe

Preheat oven to 400 degrees F (200 degrees C). Lightly grease an 8-inch square baking dish.

Combine sugar butter and vanilla extract in a large bowl; beat with an electric mixer until smooth and creamy. Add eggs one at a time beating well after each addition.

Combine cornstarch cocoa powder and salt in a bowl and sift over the sugar-butter mixture. Beat in slowly with a wooden spoon or spatula until all ingredients are well incorporated. Fold in chopped chocolate and let batter rest for 5 minutes. Pour brownie batter into the prepared baking dish.

Bake in the preheated oven until a toothpick inserted into the middle comes out clean about 20 minutes. Remove from oven. Let cool completely before cutting into squares about 15 minutes.
