Notes on Ingredients

Brownie Ingredients

Granulated sugar (1 cup / 200 g)  – Sweetens the brownies and helps create a tender texture.

Unsalted butter, melted (½ cup / 115 g)  – Adds richness and moisture; melting ensures fudginess.

Eggs (2 large, room temp)  – Provide structure, help bind ingredients, and contribute to a chewy texture.

Vanilla extract (1 tsp)  – Enhances chocolate flavor and adds aroma.

Gluten-free all-purpose flour (¾ cup, 1:1 blend)  – Base for the brownies; a 1:1 blend usually contains rice flour, potato starch, and tapioca flour for proper texture.

Unsweetened cocoa powder (½ cup)  – Provides chocolate flavor. Use natural or Dutch-processed, as preferred.

Salt (¼ tsp)  – Balances sweetness and enhances chocolate flavor.

Baking powder (½ tsp)  – Gives a slight lift; optional if you want to denser brownies.

Frosting Ingredients

Heavy cream (½ cup)  – Makes a creamy, smooth frosting when combined with chocolate.

Semi-sweet chocolate chips (1 cup, gluten-free)  – Main chocolate component for frosting; check labels to ensure gluten-free.

Butter (1 tbsp)  – Adds shine and richness to the frosting.

How to Make these Gluten-Free Cosmic Brownies

Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper.

Whisk sugar and melted butter in a bowl until smooth.

Add eggs and vanilla; mix until glossy.

Combine gluten-free flour, cocoa powder, salt, and baking powder in another bowl.

Gently fold the dry ingredients into the wet mixture, mixing only until incorporated.

Spread batter evenly in the prepared pan.

Bake for 20–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs attached. Cool completely.

For the Frosting:

Heat cream until just simmering. Pour over chocolate chips and butter.

Let sit for 2 minutes, then stir until smooth.

Spread the frosting evenly over the cooled brownies, then immediately top with sprinkles.

Chill for 30–45 minutes, then cut into squares.

Tips

• For extra fudgy brownies, slightly underbake.
• Use a certified gluten-free flour blend that already contains xanthan gum.
• Chill before slicing for clean, bakery-style edges.

• Refrigerator:  Keep refrigerated for up to 7 days for firmer texture and longer freshness.
• Freezer:  Wrap individual brownies tightly and freeze for up to 2 months. Thaw at room temperature before serving.
