• 1 box yellow cake mix

• ¾ cup water

• 1/3 cup vegetable oil

• 3 large eggs

• 1 tsp LorAnn marshmallow flavor oil

• Cupcake liners

• 1¼ cups salted butter, softened

• 3 tbsp browned butter (see tip below)

• 3 tbsp milk, half and half, or cream

• 4 cups powdered sugar

• 1 bag Yummallo Popcorn Marshmallows

• 1 large piping bag + round frosting tip

Step 1: Preheat your oven to 350°F. Line a standard muffin tin with cupcake liners.
Step 2: In a large bowl, mix the yellow cake mix, water, oil, marshmallow flavoring, and eggs. Beat on medium until fully blended.
Step 3: Fill each cupcake liner 2/3 full. Bake for 18–20 minutes, or until a toothpick comes out clean. Let cool completely.

Step 4: In another bowl, beat the softened butter until fluffy. Mix in your browned butter.
Step 5: Slowly add powdered sugar one cup at a time, alternating with tablespoons of milk or cream. Mix until smooth and creamy.
Step 6: Fill a piping bag with your frosting and frost each cupcake.
Step 7: Top with 2–3 Yummallo Popcorn Marshmallows to complete the popcorn illusion. Serve & enjoy!

Add 4 tablespoons of salted butter to a microwave-safe bowl. Microwave on high for 3 minutes. Watch closely—it will be HOT! The butter will be golden brown and full of rich, nutty flavor.

Want to go extra cute? Serve them in mini popcorn boxes from the party aisle or add a red + white striped wrapper to match the theme!
