You will need:
¾ cup Mayonnaise (This is not a typo. It sounds strange but trust us.)
1- Preheat oven to 400 degrees. Spray six 6oz. custard/ramekin cups generously with cooking spray or coat with butter. Arrange cups on baking sheet.
2- Place contents of Chocolate packet in microwave safe bowl. Melt in microwave for 45 seconds or until slightly melted. DO NOT OVERCOOK. Stir to finish melting.
3- Add Mayonnaise to melted chocolate and stir until smooth. Add Cake Mix and stir until blended. Add eggs and stir again until blended.
4- Divide mixture evenly between 6 cups. Place cups on baking sheet and bake on middle rack of oven for 8-9 minutes. Cakes should look firm around edges and liquid in the center. DO NOT OVERBAKE.
5- Place baking sheet on cooling rack and let stand for 5 minutes. Run a sharp knife around the edges of the cake to loosen. Carefully unmold by placing a plate over the top of the cake and invert. Remove cup and serve warm.
