Step-by-Step Instructions
- In a 12- to 14-ounce ceramic mug, combine granulated sugar, unsweetened cocoa powder, all-purpose flour, baking powder, and a pinch of salt. Use a fork to whisk together until thoroughly blended.
- Add sour cream, a large egg yolk, chocolate chips, and a splash of water to the dry mixture. Stir vigorously until everything is smoothly combined, with no lumps.
- Place your mug in the microwave and cook on high for 1 to 1½ minutes, watching for it to rise and look slightly wobbly. Avoid overcooking.
- Carefully remove the mug from the microwave and allow the cake to cool for about 1 minute before serving.

Notes
Store leftovers in an airtight container in the fridge for up to 3 days. For longer storage, freeze slices for up to 2 months. Warm in the microwave before serving for the best experience.
