How to make Root Beer Cupcakes

Some of the most important things to keep in mind when you’re making these cupcakes is that you need to be certain to use cupcake liners so they don’t stick. I’ve seen too many people think that they can skip this step, by why?

Cupcake liners protect your cupcake and that’s the best part!

As you can see, you are literally going to be adding in root beer to make this cake mix. Not only is there root beer in the cupcakes but there’s also root beer in the frosting, too.

That’s double the root beer flavor for your taste buds to have a true delight!

How do you know when the cupcakes are done baking?

The easiest way to know that they’re done baking is to do the toothpick test. Take a clean toothpick and insert it into the center of the cupcake. If it comes out clean, the cupcakes are done baking. If there is still batter on it, the cupcakes need more time to cook.

How to store cupcakes once cooked?

Make certain that you store these cupcakes in an air-tight container. I like to keep my cupcakes in the fridge but you don’t have to if you don’t want to.

Are you ready to make these cupcakes on your own? You’re going to love how simple and easy this cupcake recipe is! You’ll never want to make cupcakes again without using a cake mix!

Put the frosting into a piping bag and cut off the tip. Swirl on the top of each cupcake.

Put a cherry on top and enjoy!
