Inside Out Cupcakes transform the magic of Riley's emotions into bite-sized treats perfect for movie nights or parties. Each cupcake hides a colorful marshmallow frosting surprise inspired by the Inside Out characters including the new addition of anxiety with bright orange. The fluffy cakes are capped with cloudlike frosting and plenty of rainbow confetti for a burst of color and fun. Using a boxed mix means you spend more time creating the whimsical fillings and less on measuring flour. These cupcakes are a playful way to celebrate the joy and sweetness of the movie right at home.

I made these with my little ones the day after we rewatched the movie and it turned decorating into a storytelling adventure. The colors and flavors made everyone light up at first bite.

Ingredients

  • Yellow cake mix: the base for moist easy cupcakes choose a trusted brand for consistent rise
  • Eggs oil and water: for cake mix follow package instructions for best results
  • Unsalted butter: softened to create a rich smooth frosting
  • Marshmallow Fluff: for a light sweet taste reminiscent of Cloud Town
  • Kosher salt: to balance the sweetness
  • Confectioners sugar: for structure in frosting sift if lumpy for smoothness
  • Pure vanilla extract: for warm round flavor always use real vanilla for best taste
  • Assorted food colors: yellow blue green orange purple red gel food coloring gives vibrant results

Tips

Look for a cake mix with good reviews and avoid those with long shelf lives for fresher results. Use a quality vanilla extract and a fresh jar of Marshmallow Fluff for best frosting texture.

Step-by-Step Instructions

Prepare Cupcake Batter:
Mix the yellow cake mix in a large bowl as directed on the package. Evenly portion the batter into cupcake liners set in two muffin tins to ensure even baking.
Bake and Cool:
Slide the tins in a preheated oven at the temperature on the mix box. Bake until a toothpick emerges clean from the center of a cupcake usually around fifteen minutes. Cool thoroughly on a wire rack this keeps the cakes fluffy and prevents melting the filling later.
Make Marshmallow Frosting:
In a stand mixer with paddle add the softened butter Marshmallow Fluff and salt. Beat until fully blended and light in color stopping to scrape the sides for evenness. Slowly add the confectioners sugar and vanilla and whip until you see soft peaks and the mix is airy.
Color and Bag the Emotional Fillings:
Portion out a fourth cup of frosting each into six small bowls. Tint each one its emotion yellow for joy blue for sadness green for disgust orange for anxiety purple for fear and red for anger. Scoop each color into its own resealable plastic bag and snip one corner for piping.
Fill Cupcake Centers:
Use a half teaspoon to remove a small well from the center of each cooled cupcake about half an inch deep. Pipe a different color into four cakes at a time so each emotion is represented evenly among the batch.
Frost and Decorate:
Generously spread the remaining white marshmallow frosting over each top using a spatula or piping bag for swirls. Shower with rainbow confetti sprinkles before the frosting sets so they stick beautifully.

I love the look of anxiety’s orange filling the best It pops in photos and is such a fun nod to the sequel. The first time we made these my daughter cheered when she discovered her favorite inside.

Storage Tips

Once cooled and decorated store cupcakes in an airtight container at room temperature for up to two days. To keep them moist longer wrap each in plastic wrap and freeze. Thaw at room temperature for an hour for best flavor.

Ingredient Substitutions

Vanilla cake mix can work instead of yellow if that is all you have on hand. You can swap out Marshmallow Fluff with another marshmallow cream or even homemade if you prefer. For food colorings natural brands work but will be less vivid.

Serving Suggestions

Arrange cupcakes on a large platter in emotion-themed groups or in a rainbow spectrum for extra visual wow. Great to pair with a movie marathon and even better when the kids reveal their “emotion” filling after the first bite.

Required Ingredients

→ Cupcakes

01 1 box (375 g) yellow cake mix, plus ingredients required on the package (commonly eggs, oil, and water)

→ Frosting

02 340 g unsalted butter, softened
03 200 g Marshmallow Fluff
04 0.5 teaspoon kosher salt
05 460 g confectioners' sugar
06 1 teaspoon pure vanilla extract
07 Yellow, blue, green, orange, purple, and red food coloring

→ Decoration

08 Rainbow confetti sprinkles

Step-by-Step Instructions

Step 01

Preheat oven to 175°C. Line two standard 12-cup cupcake tins with paper liners.

Step 02

In a large bowl, prepare yellow cake mix according to the package directions using the specified eggs, oil, and water. Evenly divide the batter among the lined cupcake cups.

Step 03

Bake the cupcakes for 13 to 18 minutes or until a tester inserted in the center comes out clean. Allow cupcakes to cool completely in the tins.

Step 04

In the bowl of a stand mixer fitted with a paddle attachment, or using a handheld mixer, beat softened butter, Marshmallow Fluff, and kosher salt on medium speed until light and fluffy, scraping the bowl as needed, about 1 to 2 minutes. Gradually add confectioners' sugar and mix on low speed until fully combined. Add vanilla extract, then increase the speed to medium-high and beat until the frosting is airy and smooth, about 2 to 3 minutes.

Step 05

Divide 60 ml (1/4 cup) portions of frosting into six bowls. Tint each with a different food coloring: yellow, blue, green, orange, purple, and red, representing each emotion theme. Transfer each colored frosting to separate resealable plastic bags and set aside. Refrigerate the remaining white frosting.

Step 06

Using a 2.5 ml (1/2 teaspoon) measuring spoon, scoop out a 1.25 cm deep well from the center of each cooled cupcake. Cut a 1.25 cm wide opening in one corner of each colored frosting bag. Pipe a generous amount of each colored frosting into four cupcakes per color, for a total of 24 filled cupcakes.

Step 07

Frost the tops of the filled cupcakes with the reserved white marshmallow frosting. Garnish each cupcake with rainbow confetti sprinkles.
