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.

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.

Cultural Context
These cupcakes draw on the playful colors and themes of the Inside Out movies making baking an interactive experience for children and adults. They bring the world of animated emotion to your real kitchen and are a sweet way to bond over shared favorite films.
