Craving something sweet? This quick and easy chocolate mug cake is the perfect solution. In a microwave-safe mug, whisk together flour, sugar, cocoa powder, baking powder, and a pinch of salt. Add milk, vegetable oil, and vanilla extract, and mix until smooth. Microwave the mug on high for about 1-2 minutes, or until the cake has risen and is set in the center. Be careful not to overcook, as the cake can become dry. Let the mug cake cool for a minute or two, then dig in with a spoon. The rich and chocolatey cake is perfect for satisfying your sweet tooth in a matter of minutes. Top with a dollop of whipped cream or a sprinkle of powdered sugar for an extra indulgence.
