Ingredient Notes
- Yellow cake mix: Using milk, sour cream, and oil helps keep the cake soft and moist instead of dry.
- Sprinkles: Use jimmies or a sprinkle blend that won’t bleed too much into the batter.
- Freeze-dried strawberries: These add a natural strawberry flavor without thinning the frosting.
- Strawberry jam or puree: Just a small amount gives the frosting a light fruity touch.
- Heavy cream: Start with 4 tablespoons and add more as needed for a smooth, spreadable texture.
- Food coloring: A little goes a long way for a soft pink shade.
Quick Prep Notes
Do I need to use a 13 x 9 pan?
Yes, a standard 13 x 9-inch pan works best for this cake. It gives you the right thickness and helps the cake bake evenly.
Can I skip the strawberry extract?
Absolutely. The frosting already has a light strawberry flavor from the freeze-dried berries and jam. The extract just boosts it slightly if you want more flavor.
What kind of sprinkles should I use?
Jimmies or a sprinkle blend made for baking are best. They hold their color better and won’t melt into the batter as much.

*Note: This makes enough for a thick, generous layer of frosting or for frosting plus a decorative border. For a lighter layer, cut the ingredients in half.
- 1 cup salted butter, softened
- 3 1/2 cups powdered sugar
- 1/4 cup freeze-dried strawberries, crushed into a fine powder

Instructions
- Preheat your oven and prepare a 13 x 9 inch pan with nonstick spray or parchment.
- In a large bowl, mix together the cake mix, milk, sour cream, oil, and eggs until smooth. Gently fold in the pink sprinkles.
- Pour the batter into the prepared pan and bake until lightly golden and set in the center, following the timing on the package. Let the cake cool completely before frosting.
- For the frosting, beat the softened butter until smooth and creamy. Add the powdered sugar, strawberry powder, jam, 4 tablespoons of the heavy cream, and a few drops of pink food coloring. Beat until fluffy. Add more cream as needed to reach a smooth, spreadable texture. Mix in the strawberry extract if using.
- Spread the frosting evenly over the cooled cake. Finish with lots of pink sprinkles and edible butterflies.
- Slice, serve, and enjoy the sprinkle-filled fun.
