Total Time 1 hour 3 minutes

Ingredients

¼ cup heavy cream
½ cup vegetable oil
¾ cup rainbow jimmies
1 box (15.25 oz) yellow cake mix
1 box (3.4 oz) instant vanilla pudding (dry)
1 cup buttermilk (or milk)
1 cup sour cream
1½ cups (3 sticks) unsalted butter, softened
2 tsp clear vanilla
2 tsp clear vanilla extract
4 large egg whites (or 3 whole eggs)
5 cups powdered sugar

Instructions

Preheat oven to 350°F and line 24 cupcake tins with pretty liners.
In a large bowl, beat egg whites, oil, sour cream, buttermilk, and vanilla until smooth.
Add dry cake mix and pudding mix; beat 2 minutes until thick and fluffy.
Gently fold in ¾ cup rainbow jimmies—don’t over-stir or colors bleed.
Fill liners ⅔ full (ice cream scoop makes this easy!).
Bake 17–20 minutes until tops spring back and toothpick has moist crumbs.
Cool in pan 5 minutes, then transfer to rack to cool completely.
Make buttercream: beat butter until creamy, gradually add powdered sugar, cream, vanilla, and salt until light and fluffy.
Pipe tall swirls using a large star tip (1M is perfect).
Shower with extra sprinkles, add a candle if it’s someone’s big day, and watch faces light up!

Notes

Clear vanilla keeps frosting bright white—worth it for that classic birthday look.
Make cupcakes a day ahead—flavor improves overnight.
Freeze unfrosted cupcakes in a single layer, then bag them for instant party prep.
Kids love pressing extra sprinkles on top—perfect helper job!
