cake in a mug

A quick (microwave) version of a molten chocolate cake, this chocolate salted caramel mug cake is delicious and rich.  I found that 3 people could share one mug and be very satisfied (or one person could be greedy and binge).

In a mug mix together 4 Tbs. self-rising flour, 4 Tbs. sugar, and 3 Tbs. unsweetened cocoa powder.  Add in 2 Tbs. beaten egg, 3 Tbs. milk, 2 Tbs. vegetable oil, and 1/2 tsp. vanilla extract and stir well until combined.  Swirl in 2 Tbs. caramel sauce (I like Trader Joe's salted caramel sauce) and sprinkle the top with sea salt.  Microwave on high for 1 minute or until the top is just dry.
