Cinnamon Churro Mug Cake

In a microwave-safe mug, combine all-purpose flour, granulated sugar, baking powder, baking soda, and ground cinnamon.

Add whole milk, vegetable oil, and pure vanilla extract to the mug.

Stir the mixture until a smooth batter forms; a few lumps are acceptable.

Spoon the roughly chopped dark chocolate into the center of the batter.

Microwave the mug cake for 60 seconds or until it has risen and is firm to the touch. (Note: Timing is based on a 1200W microwave; adjust accordingly for different power levels.)

In a small bowl, combine 1 tablespoon of granulated sugar and 1 teaspoon of ground cinnamon for the topping. Generously sprinkle the cinnamon sugar mixture over the freshly microwaved mug cake. Enjoy immediately!
