In a small bowl, whisk together the vegetable oil, milk, egg and vanilla. Add the flour, sugar, and cocoa and whisk to combine.
Divide the chocolate chips between two medium microwave-safe mugs. Pour batter into the mugs over the chocolate chips.
Microwave on "high" for 90 seconds. Check to see if the cakes are puffed and bounce back after being lightly touched. If not, microwave for an additional 30 seconds. Serve immediately.
