How to Make Root Beer Cupcakes


Preheat the oven to 350°F (175°C) and line a muffin tin with paper liners.

In a spacious mixing bowl, combine room temperature butter and eggs, allowing them to sit for 30 minutes.


Mix root beer with oil and eggs.

Tip: Break the eggs individually into a custard cup or small bowl first. This way, if any shell fragments get in, you can easily remove them before mixing the batter.

Slowly blend the cake mix into the root beer, ensuring a smooth fusion.

Add the root beer flavoring, mixing until fully incorporated, and regularly scrape the bowl for even blending.



Once blended, add root beer concentrate

Fill each liner about 3/4 full (approximately 1/4 cup / 60 ml of batter).

Bake for 20 minutes or until a toothpick emerges clean from a cupcake’s center.

Let cupcakes cool in the pan for 5 minutes before transferring them to a wire rack for complete cooling.

Optional: Filling the Cupcakes:

  1. Utilize a pastry bag or resealable bag with a Bismark tip for filling cupcakes.
  2. Fill the bag with frosting and insert the tip into the top of a cupcake. Squeeze gently to infuse the filling. Don’t worry if you leave a hole, as the frosting will cover it. 
  3. Alternatively, use a melon baller to create a cavity, fill with frosting, and top with more frosting.

For Root Beer Buttercream Frosting (Optional):

    1. In a separate bowl, beat room temperature butter until smooth and creamy.
    2. Gradually add powdered sugar, mixing until well combined.
    3. Introduce root beer and root beer flavoring, continuing to beat until the frosting achieves a light, fluffy texture.

Decorating the Cupcakes:

  1. Frost the cooled cupcakes with the Root Beer Buttercream Frosting or your favorite frosting.
  2. For a fun touch, make the cupcakes look like mugs of root beer floats. Add white frosting to the top of each cupcake, insert a paper straw, and top with a maraschino cherry.

Cooking Time Guidelines for Different Cupcake Sizes:

  • Mini Cupcakes: A recipe that makes 24 (2½-inch) cupcakes will make about 64 mini cupcakes. Bake at 350°F oven for typically 10 to 15 minutes.
  • Jumbo Cupcakes: A recipe that makes 24 (2½-inch) cupcakes will make 10 to 16 jumbo cupcakes. Bake in a 350°F oven for typically 25 minutes.

Enjoy these delightful Root Beer Cupcakes with or without the Root Beer Buttercream Frosting, and let the nostalgic flavors of a classic root beer float whisk you away to sweet satisfaction. Happy baking!

Today's Best Recipe is root beer cupcakes. The old-fashioned flavor of root beer makes these cupcakes a delicious treat.


  • 1 box vanilla or white cake mix
  • 1 1/3 cup root beer soda
  • 1/3 cup oil (I prefer the Mediterranean oil, but vegetable oil will work just as well)
  • 3 eggs
  • 3 Tablespoons root beer concentrate (or you can use root beer extract)
  • 1 teaspoon vanilla extract (optional)


  1. 1. Preheat oven to 335 degrees
  2. 2. Add cupcake liners to cupcake pan (this recipe makes 24 cupcakes).
  3. In a large bowl mix root beer with oil and eggs by hand or using an electric mixer on medium speed


  1. Place your butter and eggs on the counter for 30 minutes to allow them to come to room temperature.
  2. This will help them blend easier and the eggs will incorporate more air giving your cupcake batter a lighter texture.


  1. Break eggs individually into a custard cup or small bowl first.
  2. This way, if you get shell fragments, you can easily fish them out of the cup rather than try to get them out of the batter.
  3. 4. Stirring slowly, gradually add the boxed cake mix to the rootbeer mixture.
  4. 5. Once blended, add root beer flavoring.
  5. 6. Use a rubber spatula to scrape the sides of the bowl regularly until well mixed.
  6. 7. Fill paper liners about 3/4 full…(about 1/4 cup of batter).


  1. Standard 2½-inch cupcakes should have 1/4 cup batter to fill the liner 2/3 to 3/4 full.
  2. Adding more batter than this will cause the cupcakes to overflow the cups and create a mess in your oven.

Quick Ways to fill cupcake liners with cupcake batter:

  1. If the batter is thick, use two spoons to scoop it into the cups.
  2. Use a medium ice cream or cookie scoop to spoon batter into the cups.
  3. Fill a resealable plastic bag with batter and clip a small hole in one corner. Place your hole over the hole until the bag is over the cupcake liner. then squeeze the bag gently into the cups to fill. Cover the hold again with your finger to move to the next cupcake liner. (you can also use a piping bag)
  4. If your batter is thin, pour it into a large glass measuring cup. The spout on the measuring cup will make it easier to fill cupcake liners with batter.
  5. 8. Bake cupcakes in preheated oven for 20 minutes on center rack.


  1. Insert a wooden toothpick into the center of the cupcake to check the doneness.
  2. When you pull the toothpick out, it should be clean, signaling the cupcakes are done. If the toothpick is removed and shows wet batter or several moist crumbs clinging, the cupcakes need to bake longer.
  3. Allow cupcakes to cool for 5 minutes in the pan before moving to a wire rack to cool completely.
  4. 9. Fill the cupcakes, optional

How to Fill Cupcakes

  1. To fill your cupcakes with frosting or filling, use a pastry bag, or large resealable baggie and a Bismark filling Tip or a large round tip.
  2. Clip the corner of one corner if using a resealable bag.
  3. Insert the tip into the bag and then fill the bag by spooning the frosting into the bag.
  4. Squeeze the frosting down.
  5. You now have two options for filling:
  6. Insert the tip into the top of the cupcake, and squeeze the filling into the center of the cupcake. Don’t worry if you leave a hole because the frosting will cover it.
  7. You can also use a melon baller to remove the center of the cupcake, fill the hold with icing and add frosting over the top.
  8. Frost with Root Beer Buttercream Frosting, or your favorite frosting.
  9. Now for everyone's favorite part, eating the flavorful cupcakes.
