Here is the recipe for you. Good luck with your show. I hope she follows through.
Molten Chocolate Lava Cake
One box of chocolate cake mix
ingredients to make the chocolate cake (from the back of the box)
One can of chocolate frosting
Empty cake mix and cake mix ingredients into Rice Cooker Plus and mix together.
Add ½ the can of frosting with Small Scoop.
Microwave for about 8-10 minutes or until a cake tester inserted into the center of the cake comes out clean. Microwave time may vary.
This is how I've done it.
Mix the cake like you normally would, spray the rice cooker with oil, pour the cake in, spoon about 1/2 to 2/3 a can of ready made frosting into the batter and bake in the micro for about 10-12 minutes. I've done it with the lid and without. Both work but I think with the lid you get a more even surface so it sitys straighter when you invert it onto a plate.
