  • 1 15.25 oz boxed Devil’s Food cake mix
  • 1 cup smartwater® sparkling water

  • Place half of the frosting into a piping bag and spread in an even layer around the top of the cake.
  • (see note)
  • Microwave on high for 9 minutes.
  • Remove from microwave and immediately remove the cake from the pan.
  • Microwave the remaining frosting on high for 30 second increments, until melted.
  • Drizzle melted frosting on top of the cake.


Because this cake is made in the microwave, you must use a non-metallic cake pan.  I've found that silicone pans (like this one) work best.
