1 box Devil's Food cake mix
1 can Diet Coke
Preheat the oven to 350 degrees. In a medium size bowl, mix the chocolate cake mix and the Coke together until most of the lumps are gone. Using 2 mini bundt pans (spray if metal, not needed if it's a paper baking cup), and 6 cupcake wrappers, fill each 2/3 of the way full. Place the two bundt pants on a baking sheet and put those, along with the 6 cupcakes, in the oven. Bake the cupcakes for approximately 20-22 minutes. Remove those from the oven and let cool, and add 12-14 more minutes to the timer to finish the bundt cakes. Let cool fully.
For Valentines day, I added melted semi-sweet chocolate on top, and added a few love notes ;-)
