You will need:
1) 4 Oreo's
2) Microwave
3) Milk
4) Microwavable mug
5) Fork
Instructions:
1) First you need to place your Oreo's in your microwavable mug.
2) Next mash the Oreo's with a fork until they are like breadcrumbs (it doesn't matter if there are some small chunks left)
3) Then pour 3 and a half tablespoons of milk into the mashed Oreo's.
4) Finally put in the microwave for 3 minutes. BE WARNED when you take out the mug it may be hot so ask an adult for help.
5) This step is optional but I would recommend taking you mug cake out of the mug and into a tub/bowl with your fork because it makes it cool down faster.
WALA, YOUR OREO MUG CAKE IS COMPLETE NOW YOU CAN O AND ENJOY!
