✨ Ingredients

Cupcake Batter:

  • 1 box yellow cake mix

  • ¾ cup water

  • ⅓ cup vegetable oil

  • 3 large eggs

  • 1 tsp LorAnn marshmallow flavoring (or vanilla extract)

  • Cupcake liners

Brown Butter Frosting:

  • 1¼ cups salted butter, softened

  • 3 tbsp browned butter (see note below)

  • 3 tbsp milk, half and half, or heavy cream

  • 4 cups powdered sugar

Topping:

✨ Directions

  1. Preheat oven to 350°F. Line your muffin tin with cupcake liners or spray with nonstick spray.

  2. In a large bowl, combine cake mix, water, oil, marshmallow flavoring, and eggs. Beat on medium speed until smooth.

  3. Fill each cupcake liner about ⅔ full.

  4. Bake for 18–20 minutes or until a toothpick comes out clean. Cool completely before frosting.

  5. For the frosting: In a bowl, cream softened butter until fluffy. Add browned butter.

  6. Mix in powdered sugar 1 cup at a time, adding a tablespoon of milk in between each addition. Mix until creamy and smooth.

  7. Pipe frosting onto each cupcake using a round trip.

  8. Top with popcorn marshmallows and enjoy!

✨ Pro Tip: How to Brown Butter

Add 4 tablespoons of salted butter to a microwave-safe bowl. Microwave on HIGH for about 3 minutes. It will turn golden brown and smell nutty! Be careful—the container will be hot.
