This flourless Bailey's chocolate mug cake is so incredibly simple and a great way to serve up single servings for a fun St. Patrick's Day dessert!
Combine the chocolate chips and vegetable oil in a microwave safe mug and microwave them on high for about 45 seconds to melt them together. Stir them both together until you have a smooth base. Stir in the remaining ingredients, then microwave it all for another minute. The edges should get slightly crisp while still being soft in the middle. Let it sit and cool for 5 minutes, then enjoy warm with an extra sprinkle of powdered sugar on top!
