Ingredients
1 box vanilla cake mix, plus ingredients called for on box
3 (16-oz.) tubs vanilla buttercream frosting
8 drops blue food coloring
12 large marshmallows
24 mini marshmallows
2 tubes blue gel icing
Preparation
Step 1 Line a 12-cup muffin tin with cupcake liners. Prepare cupcakes according to package instructions. Let cool completely.Step 2Spoon frosting into a large, microwave-safe liquid measuring cup. Add blue food coloring, stirring until combined. Continue adding food coloring until desired blue is reached.Step 3Line a baking sheet with parchment paper and top with a wire rack. Place cupcakes upside down onto the rack, about an inch apart. Take a marshmallow, swipe one end with a little frosting, and gently place on the center of each upside-down cupcake, forming the base of Cinderella’s gown.Step 4Place the remaining frosting in the microwave, heating it for 20 to 25 seconds, then stir. It should be easily pourable.Step 5Pour frosting on top of each cupcake, pouring directly over the marshmallow and slowly spiraling outward, until the cupcake is coated entirely. If the cupcake shows through the frosting, give it a second coating.Step 6Before the frosting sets, place 2 mini marshmallows on the sides of each top marshmallow to create the puffy sleeves. Set aside for 10 minutes, so the frosting can set completely. Use gel icing to draw Cinderella’s neckline and waistline. Beneath that, finish by drawing two rows of ruffles on the cupcake itself.
