Mocha Swirl Mug Cake

Instructions

1. 1

   In a medium bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt.

2. 2

   In a separate bowl or large mug, dissolve the instant coffee in the whole milk. Stir in the melted butter and vanilla extract.

3. 3

   Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.

4. 4

   Divide the batter evenly between two large microwave-safe mugs (or use one large mug for a single serving).

5. 5

   In a small bowl, mix the cocoa powder with a tablespoon of water to form a smooth paste.

6. 6

   Drop spoonfuls of the cocoa paste onto the batter in each mug and use a toothpick or knife to swirl it gently, creating a mocha swirl effect.

7. 7

   Microwave each mug separately on high for 1 minute and 30 seconds to 2 minutes, or until the cake has risen and is set in the center.

8. 8

   Allow the mug cake to cool for a minute before serving. Enjoy warm, optionally topped with whipped cream or chocolate chips.
