In a medium bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt.
In a separate bowl or large mug, dissolve the instant coffee in the whole milk. Stir in the melted butter and vanilla extract.
Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.
Divide the batter evenly between two large microwave-safe mugs (or use one large mug for a single serving).
In a small bowl, mix the cocoa powder with a tablespoon of water to form a smooth paste.
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.
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.
Allow the mug cake to cool for a minute before serving. Enjoy warm, optionally topped with whipped cream or chocolate chips.
