Ingredient Notes
- White cake mix: A white or vanilla cake mix works best for that classic, light color that lets the pink frosting really stand out.
- Sour cream: This keeps the cake soft and bakery-style, so don’t skip it.
- Whole milk: Adds richness to the batter. You can use 2% if needed, but whole milk gives the best texture.
- Salted butter: If you only have unsalted, just add a small pinch of salt to the frosting.
- Powdered sugar: Start with 3½ cups and add more if you want a thicker frosting for clean layers.
- White chocolate: Use melting wafers or a good-quality bar so the drip stays smooth and glossy.
- Valentine’s sprinkles: Mix some into the layers and save extra for the top so the cake feels fun and party-ready.
Quick Prep Notes
Can I make this cake ahead of time?
Yes. You can bake the cake layers a day in advance, wrap them tightly, and frost the next day. It actually makes assembly easier.
Do I have to use two round pans?
Two 9-inch rounds give you the layered party look, but you can also bake it in a 9×13 pan and decorate the top the same way.
How pink should the frosting be?
Totally up to you. A soft blush looks sweet, and a brighter pink makes it more fun.
Cupid’s Pink Sprinkle Party Cake
Ingredients
- 1 box white cake mix (15.25 oz)
- 1 cup whole milk
- 1/2 cup vegetable oil
- 3 large eggs
- 1/2 cup sour cream
- 1 cup salted butter, softened
- 3 1/2 to 4 cups powdered sugar
- 4 to 6 tablespoons heavy cream or whole milk
- 2 teaspoons vanilla extract
- Pink food coloring
- 6 oz white Ghirardelli melting wafers or high-quality white chocolate, chopped
- 2 oz heavy cream (1/4 cup)
- 1/2 to 3/4 cup Valentine’s sprinkles, divided
Instructions
- Preheat your oven to 350°F. Grease and line two 9-inch round cake pans with parchment paper.
- In a large bowl, beat together the cake mix, milk, oil, eggs, and sour cream until smooth and thick, about two minutes. Gently fold in the white chocolate. Divide the batter evenly between the pans and smooth the tops. Bake for 20 to 25 minutes, until a toothpick comes out clean. Let the cakes cool completely.
- Beat the butter until creamy. Gradually mix in the powdered sugar, then add the vanilla and 4 tablespoons of cream. Beat until light and fluffy, adding more cream if needed. Tint with pink food coloring to your favorite shade.
- Place one cake layer on a serving plate. Spread with a generous layer of buttercream and sprinkle with Valentine’s sprinkles. Top with the second layer and frost the top and sides. Chill for 15 to 20 minutes to set.
- Heat the cream until steaming, then pour it over the white chocolate. Let it sit for a few minutes, then stir until smooth and glossy. Once slightly cooled, spoon the ganache around the edges of the cake for a natural drip effect. Finish with more sprinkles on top.
FAQ
Can I use a different cake mix flavor?
Yes. Vanilla or French vanilla both work great and still keep the cake light in color.
What if my ganache is too thick?
Stir in a splash of warm cream until it’s smooth and pourable.
Can I skip the white chocolate drip?
You can, but it adds that party cake look everyone loves.
How should I store the cake?
Keep it covered in the fridge and let it sit at room temp for about 20 minutes before serving.
Can I use different sprinkles?
Absolutely. Any pink, red, or heart sprinkles work for Valentine’s Day.
