Went on a virtual manhunt for this recipe tonight and after I found it, I figured I should share with all of you :) Enjoy! I will definitely be making these some time soon. If you do so before me, please send pics and give me your feedback!
Preheat the oven to 350 degrees F. In a large bowl mix together the cake mix, heavy cream, vegetable oil, eggs, and brown sugar. Line a 12-count muffin pan with cupcake liners.
Cut the KitKat bars in half and place one half in the bottom of each cupcake liner.
Pour the batter into each liner, splitting the batter evenly amongst the liners, and place the pan in the oven for 23 minutes. Once they are done remove them from the oven and let them cool for 10 minutes.
Now for the fun part! When they have cooled off you can begin to ice them, using the fudge frosting. After that, you can place some KitKatshavings and the other half of the bar on top of it for garnish.
