How to Make Gooey Root Beer Float Brownies
-
Preheat your oven to 375°F and grease a 9×13 inch baking dish using butter or cooking spray. It’s important to prepare your dish first to ensure easy brownie removal later.
-
Reduce 1/4 cup of root beer in a small saucepan over medium heat until it becomes a rich syrup, about 5 minutes. Allow it to cool completely before adding to your mix for an extra flavor boost.
-
Whisk together the flour, cocoa powder, and salt in one bowl until well blended. In another bowl, melt the semisweet chocolate chips, white chocolate chips, and cubed butter over a double boiler or in the microwave. Stir until smooth, then let it cool for 5 minutes.
-
Mix room-temperature eggs, granulated sugar, brown sugar, and vanilla extract in a large mixing bowl. Whisk for 2-3 minutes until thick and pale, creating the perfect base for your brownies.
-
Combine the cooled chocolate mixture with the egg mix and stir gently until just combined. Carefully fold in the dry ingredients, then add in 16 oz of root beer until the mixture is just barely combined, taking care not to overmix.
-
Pour the batter into your prepared dish, spreading it into an even layer. Bake for 35-40 minutes until the top appears set and a toothpick inserted comes out with a few moist crumbs. Let cool completely in the pan.
-
Beat the softened butter in a bowl until creamy. Gradually mix in the sifted powdered sugar, followed by the reduced root beer concentrate and root beer extract. Continue beating until fluffy and spreadable.
-
Spread the root beer frosting evenly over the cooled brownies. For cleaner cuts, chill in the refrigerator for at least 30 minutes before slicing into squares.
Optional: Drizzle extra root beer syrup on top for an indulgent finish.

Expert Tips for Gooey Root Beer Float Brownies

Gooey Root Beer Float Brownies Recipe FAQs
How do I choose the right root beer for my brownies?
Absolutely! When selecting root beer, aim for one with a rich, bold flavor. Craft or specialty root beers often have more complex spices and vanilla notes that elevate the taste. Avoid diet versions, as they might not impart the same sweetness or carbonation that adds to the recipe’s essence.
How long will my brownies last at room temperature?
Very! If stored in an airtight container, your Gooey Root Beer Float Brownies will stay delicious for up to 3 days at room temperature. Be sure to keep them away from direct sunlight or heat sources to maintain their fudgy texture.
Can I freeze Gooey Root Beer Float Brownies?
Of course! To freeze, slice the brownies and wrap each piece tightly in plastic wrap, followed by aluminum foil. This layering protects them from freezer burn. They can be stored for up to 3 months! When you’re ready to enjoy, simply let them thaw at room temperature or heat in the microwave for about 15-20 seconds for that freshly baked gooeyness.
What should I do if my brownies come out too cakey?
Oh no! If your brownies turn out cakey, it might be due to overmixing. Make sure you blend the ingredients just until combined, especially after adding the flour mixture and root beer. Following these steps ensures that your brownies retain their coveted gooeyness!
Are there any dietary considerations I should be aware of?
Yes! If you’re baking for someone with allergies, be cautious as this recipe contains eggs, dairy, and gluten. For egg substitutions, applesauce or flaxseed meal can work well. Also, gluten-free all-purpose flour can be used as an alternative to regular flour. If you’re concerned about chocolate, choose dairy-free chocolate chips available at most grocery stores.
How should I store brownies with frosting?
Absolutely! If your brownies are frosted, it’s best to keep them refrigerated for freshness. Store them in an airtight container for up to a week. If possible, wait to frost until just before serving to ensure the frosting stays fluffy and intact!
