Instructions

1. Make this right before you plan to put it on the assembled cake!
2. Combine the heavy cream, corn syrup, and sugar in a small, microwave-safe container and heat in the microwave for 45 seconds, until it is very hot to the touch.
3. Add the white chocolate, butter, corn powder, and salt and stir vigorously to combine. Keep stirring until the white chocolate and butter have melted. If it seems like the white chocolate and butter are not going to fully melt, heat the mixture in the microwave in 10-second intervals, stirring in between, until everything has melted together. Give the mixture one more vigorous stir to make sure everything is evenly incorporated.
4. Use the corn fudge immediately, while it is still warm, to top the cake.
