In medium-sized bowl, add egg and beat slightly. Mix in all other ingredients except chocolate chips. Once all ingredients are mixed well, fold in chocolate chips.
Tip your bowl to pour your pudding mix and fill your mug almost to the top. Use a spatula if needed.
Place mug in microwave and heat on HIGH for about 3 to 3 ½ minutes. Microwave times may vary according to the wattage of your microwave. There should be just a little glossiness on the top of the pudding. Test for doneness with a toothpick. Let sit for about another 3 minutes before digging in!
