How to Make Root Beer Float Cupcakes
-
Preheat oven: Start by setting your oven to 375°F (190°C). Line a cupcake pan with paper liners, so your cupcakes are easy to remove after baking.
-
Combine ingredients: In a large mixing bowl, mix together the vanilla cake mix, root beer, root beer extract, vegetable oil, and eggs. Stir until everything is well combined and smooth.
-
Fill liners: Spoon the batter into each paper liner, filling them about 2/3 full. This allows room for the cupcakes to rise beautifully while baking.
-
Bake cupcakes: Place the pan in your preheated oven and bake for 15-18 minutes, or until a toothpick inserted in the center comes out clean. Let them cool completely in the pan.
-
Make frosting: For the frosting, beat together softened salted butter, powdered sugar, and root beer using an electric mixer until smooth and creamy. This should take about 3-5 minutes.

Expert Tips for Root Beer Float Cupcakes
-
Mixing Method: Ensure you combine the wet and dry ingredients gently to avoid overmixing, which can lead to dense cupcakes instead of the light texture you desire.
-
Cooling Time: Allow the cupcakes to cool completely before frosting; warm cupcakes can cause the frosting to melt, ruining that beautiful finish.
-
Frosting Consistency: If your frosting is too thick, add more root beer, one tablespoon at a time, until it’s pipeable. A perfectly smooth frosting complements these root beer float cupcakes beautifully.
-
Experiment with Flavors: Feel free to try different soda flavors or extracts! Adding a hint of vanilla or even a splash of chocolate can add a twist to your root beer float cupcakes.
-
Serving Suggestions: To keep your cupcakes as fresh as possible, store them in an airtight container. They’re best enjoyed within a few days but can also be frozen for longer enjoyment!
