4 large eggs – Binds the ingredients and adds structure.
1 teaspoon vanilla extract – Enhances flavor complexity.
1 cup all-purpose flour – Forms the base structure of the brownies.

1 teaspoon baking powder – Helps the brownies rise slightly without over-expanding.
1/2 teaspoon salt – Enhances all flavors and balances sweetness.
1/2 cup root beer – Infuses the brownies with signature soda flavor.

For the Frosting:

1/2 cup (1 stick) unsalted butter, softened – Base for creamy frosting.
2 cups powdered sugar – Sweetens and thickens the frosting.
2 tablespoons heavy cream – Adds smoothness and spreadability.
1 teaspoon vanilla extract – Enhances flavor.
2 tablespoons root beer – Provides the root beer float flavor in the frosting.

Step-by-Step Instructions

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper for easy removal of brownies.

Step 2: Mix the Wet Ingredients
In a large mixing bowl, whisk together melted butter and granulated sugar until smooth. Add eggs and vanilla extract, whisking until fully combined and glossy.

Step 3: Combine the Dry Ingredients
Sift together flour, cocoa powder, baking powder, and salt in a separate bowl. This ensures even distribution and a light texture.

Step 4: Combine Wet and Dry Ingredients
Gradually fold the dry ingredients into the wet mixture until just combined. Avoid overmixing. Stir in root beer until the batter is smooth and uniform.

Step 5: Bake the Brownies
Pour batter evenly into the prepared pan. Bake 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

Step 6: Cool the Brownies
Allow brownies to cool in the pan for 30 minutes, then transfer to a wire rack to cool completely before frosting.

Step 7: Prepare the Frosting
In a medium bowl, beat softened butter until creamy. Gradually add powdered sugar, then mix in heavy cream, vanilla extract, and root beer until smooth and fluffy.

Step 8: Frost the Brownies
Spread the frosting evenly over completely cooled brownies. Cut into squares and serve.

Recipe Notes & Tips

Do Not Overbake – Bake until a few moist crumbs stick to a toothpick to ensure fudgy brownies.
Even Root Beer Flavor – Stir root beer into batter and frosting thoroughly to distribute flavor.
Cooling Is Key – Frost only when brownies are fully cooled to prevent melting.
Storage – Store in an airtight container at room temperature for 2–3 days or refrigerate for up to 5 days.
Optional Garnish – Top with a drizzle of chocolate or a few soda-infused sprinkles for extra flair.
Adjust Sweetness – Reduce powdered sugar slightly if you prefer a less sweet frosting.
