This birthday cake popcorn transforms ordinary movie night into a festive celebration with its sweet, colorful charm. I created this recipe for my daughter's sleepover party, and it's become our most requested treat for gatherings year-round.
I first made this on a rainy afternoon when my kids were bored and craving something sweet. The moment they tasted that cake batter flavor combined with the satisfying crunch of popcorn, I knew we had discovered our new favorite family snack.
Ingredients
- Popped popcorn: the base of our treat air popped works best to avoid competing with butter flavor
- White chocolate chips: creates the creamy coating that holds everything together use high quality for best melting
- White cake mix: this secret ingredient brings that authentic birthday cake flavor
- Sprinkles: adds festive color and extra sweetness choose jimmies or nonpareils based on your preference
Step-by-Step Instructions
- Prepare the popcorn:
- Pop 6 cups of popcorn using your preferred method. Take extra time to remove any unpopped kernels at the bottom of the bowl this prevents unwanted dental surprises. Place the cleaned popcorn in a large mixing bowl, ensuring you have plenty of room to stir without spilling.
- Melt the chocolate:
- Pour 12 ounces of white chocolate chips into a microwave safe bowl. Heat for one minute at 50% power, then stir thoroughly. Continue heating in 20 second intervals, stirring between each, until completely smooth. The chocolate should be warm but not hot to touch. Patience here prevents scorching the chocolate, which can create a bitter taste.
- Create the cake batter coating:
- Add between ¼ to ½ cup of dry white cake mix to the melted chocolate. Start with the smaller amount and adjust to taste some prefer a subtle hint while others love a stronger cake flavor. Stir until completely incorporated, with no visible powder streaks. The mixture should be smooth and pourable but not too runny.
- Coat the popcorn:
- Pour the white chocolate mixture over the popcorn in a slow, steady stream while simultaneously stirring with a silicone spatula. Fold gently but thoroughly until every piece is evenly coated. Work quickly before the chocolate begins to set, but take care not to crush the popcorn.
- Add the festive touch:
- Immediately transfer the coated popcorn to a baking sheet lined with wax paper or a silicone mat. Spread it out in an even layer before the chocolate hardens. Generously sprinkle with colorful sprinkles, gently pressing them into the coating to ensure they stick.
- Let it set:
- Allow the popcorn to rest undisturbed for approximately 30 minutes at room temperature until the coating has completely hardened. For faster setting, place in the refrigerator for 10 minutes, but no longer as condensation can make the popcorn soggy.
- Break and serve:
- Once set, break the popcorn into bite sized clusters. Transfer to a serving bowl for immediate enjoyment or store in an airtight container.

My favorite thing about this recipe is watching guests try to identify that mysterious cake flavor. The moment of recognition when they realize it tastes exactly like birthday cake never fails to bring smiles. My son once called it "birthday cake that crunches" which perfectly captures its appeal.
Making Ahead and Storage
This birthday cake popcorn stays fresh for up to one week when stored properly in an airtight container at room temperature. For maximum freshness, place a paper towel in the bottom of your storage container to absorb any excess moisture that might make the popcorn lose its crunch. If you live in a particularly humid climate, consider adding a food grade desiccant packet to maintain crispness.
Creative Variations
Transform this treat for different occasions by simply changing the cake mix and sprinkles. For chocolate lovers, substitute chocolate cake mix and milk chocolate chips. During holidays, try red velvet cake mix with red and green sprinkles for Christmas, or funfetti cake mix with patriotic sprinkles for Fourth of July celebrations. For a more sophisticated adult version, add a teaspoon of vanilla bean paste to the white chocolate and finish with gold or silver shimmer sugar.
