Equipment

  • Half-sphere cake pans or oven-safe bowls
  • Mixing Bowls
  • Whisk
  • Cake Board
  • Piping Bags or Spatula

Ingredients
  

  • 1 box cake mix plus eggs, oil, and water per package instructions
  • 2 cups buttercream icing for filling and coating
  • piñata filling candies, sprinkles, or chocolates
  • mini round chocolates or candies for mirror effect
  • edible silver spray or luster dust for shine
  • toothpicks or skewers to stabilize halves if needed

Instructions
 

  • Preheat oven to temperature indicated on cake mix box. Grease and flour two half-sphere pans (or oven-safe bowls).
  • Prepare cake batter according to package instructions and divide evenly between pans. Bake until a toothpick inserted comes out clean. Cool completely.
  • Scoop out a shallow cavity in the flat side of each cooled cake half. Fill one side with candies or sprinkles for the piñata surprise.
  • Spread a thin layer of icing around the edges and gently press the two halves together to form a ball. Use skewers if needed for stability.
  • Apply a crumb coat of icing and chill for 20–30 minutes. Cover the cake with a final smooth layer of buttercream.
  • Press mini round chocolates or candies into the icing to mimic disco mirror tiles. Spray the cake with edible silver for extra shine.
  • Decorate with sprinkles, edible glitter, or metallic toppers. Place on a sturdy cake board to serve.

Notes

Be patient—assembling while warm will cause collapse. If icing won’t hold candies, soften slightly or add more icing. Place under party lights or fairy lights for maximum sparkle!
