3 oreos crushed fine (I ran mine through a food processor. the cookie must be enough so that it fits through the piping tip)
2.5 tbsp sugar
Equipment
food processor
microwave
Directions
Mix all ingredients for the cake in an oversized mug except the oreos. After batter is smooth, add in the oreos and crush oreos into batter with a metal spoon. Cook for approximately 1 1/2 minutes in microwave. Check on middle of cake. If not done, cook for about 20 more seconds. Careful not to overcook or cake becomes rubbery. Mine was done at 1 1/2 minutes.
While cake is cooling, making the frosting. Whip the heavy cream and sugar on high speed. Crush oreos separately in a food processor. Oreo crumbs must be fine enough that they fit through piping tip if you are piping the frosting. After the heavy cream becomes thick and forms peaks, gently fold in the crushed oreos before placing frosting into piping bag. The recipe makes more frosting than needed for one serving but it's hard to make a one serving frosting.
