Make a soft chocolate mug cake in the microwave in about one minute. This single-serving dessert is mixed right in the mug with simple pantry ingredients and plenty of chocolate flavor.
Add the butter to a microwave-safe mug. Microwave for 20 to 35 seconds, or until melted.
Add the flour, sugar, cocoa powder, chocolate chips, baking powder, egg yolk, water, and vanilla.
Mix thoroughly with a fork, scraping around the bottom and sides of the mug until no dry flour or cocoa remains.
Microwave on high for 50 seconds. Check the center. When it still looks shiny or wet, microwave for another 10 seconds. Continue in 10-second bursts until the top is just set.
Let the mug cake stand for 2 minutes before eating. Add your favorite topping and serve warm.

Notes
Use a large mug: Choose a microwave-safe mug that holds at least 12 ounces so the cake has room to rise.
Measure the flour lightly: Do not pack flour into the measuring spoon. Too much flour can make the cake dry.
Watch the cooking time: Microwave wattages vary. Start at 50 seconds and add time only as needed.
Do not cook until dry: The center should look soft but not like raw batter. The cake continues to set during the 2-minute rest.
Use caution: The mug will be hot after microwaving. Remove it with a potholder.
Serve promptly: Mug cake has the softest texture when eaten shortly after it is made.
