Ingredients

Scale

For the Cupcakes:

  • ¼ cup unsalted butter, thoroughly softened
  • ¼ cup neutral oil (avocado, canola, or vegetable)
  • ¾ cup granulated sugar
  • 2 large eggs, room temperature
  • 1 ½ tsp pure vanilla extract
  • 1 ½ cups all-purpose flour
  • 1 ½ tsp baking powder
  • ¼ tsp fine sea salt
  • ⅔ cup buttermilk

For the Surprise & Topping:

  • 1 batch vanilla frosting (buttercream or cream cheese)
  • ¾ cup small candies or rainbow sprinkles
  • Gel food coloring (your favorite colors)

Instructions

  1. Prep and Cream: Preheat your oven to 350°F (175°C) and line a 12-count muffin tin. Beat the soft butter, oil, and sugar on medium-high for 3-4 minutes until pale, fluffy, and textured like wet sand.
  2. Add Wet Ingredients: Beat in the room-temperature eggs one at a time, mixing well after each. Stir in the vanilla extract.
  3. Alternate the Dry Mix: Whisk the flour, baking powder, and salt in a separate bowl. Switch to a rubber spatula and alternate adding the flour mix and buttermilk to the wet ingredients, starting and ending with flour. Fold gently by hand and stop the second the last white streak disappears.
  4. Bake: Divide the batter into the liners, filling them only ⅔ to ¾ full. Bake on the center rack for 17-20 minutes. They are done when the tops spring back or a toothpick comes out clean. Cool in the tin for 5 minutes, then move to a wire rack to cool completely.
  5. Core and Stuff: Cut a 1-inch wide, 1-inch deep cone out of the top of each cooled cupcake. Slice off the pointy bottom of the cake cone to leave a flat, thin disc—this is your lid. Pour 1 tablespoon of sprinkles into the hole, then gently press the cake lid back on flush with the top.
  6. Paint and Decorate: Drop a star nozzle into a piping bag. Use a small, clean paintbrush to paint vertical stripes of gel food coloring up the inside walls of the bag. Spoon your plain white frosting down the center. Pipe a classic swirl over the cake lid to seal the secret inside.

Notes

  • Serving Suggestion: Set a small dessert knife next to each plate. Encourage guests to slice their cupcake straight down the middle to enjoy the full visual payoff of the spilling sprinkles. Pairs beautifully with a glass of ice-cold milk.
  • The Painter’s Trick: Squeeze a tiny bit of frosting onto a paper towel first until the color stripes show through evenly before you start piping onto the cupcakes.
  • Quick Buttermilk Swap: Out of buttermilk? Stir 2 teaspoons of lemon juice or white vinegar into ⅔ cup of regular milk and let it sit for 5 minutes until slightly curdled.
  • Storage Instructions: Keep these in a deep, airtight container at room temperature for 2-3 days (make sure the lid doesn’t crush your piped peaks). You can also store them in the fridge for up to a week. If refrigerated, let them sit out on the counter for 20-30 minutes before serving to restore their melt-in-your-mouth softness.
