2 minute mug cake

I admit it. I’ve succumbed to mug cakes ever since I discovered them. The ease of making them and just how delicious they are makes them wonderful!
To make this I used:
2 tablespoons vegetable oil
1/4 cup whole milk
1 large egg
1/2 teaspoon vanilla extract
1/3 cup self-rising flour
1/4 cup sugar
2 tablespoons unsweetened cocoa powder

Directions
In a small bowl, whisk together the vegetable oil, milk, egg and vanilla.
Add the flour, sugar, and cocoa and whisk to combine. Pour batter into the mugs over the chocolate chips. Microwave for 2 minutes. Check to see if the cakes are well cooked inside using a toothpick (if it comes out clean it’s ready). If not, microwave for an additional 30 seconds.
