This microwave chocolate lava mug cake is rich, fudgy, and ready in under five minutes!

Have you ever just wanted a piece of cake but didn’t want to bake an entire cake? Yeah, me too. More often than I care to admit. That’s where a mug cake comes in. You can make individually sized portions of yummy, gooey cake.

Chocolate lava cake is one of my all-time favorite desserts. A rich fudgy cake filled with warm melted chocolate. You can’t go wrong with it. Top it with some vanilla ice cream and you are golden. But making chocolate lava cake is a process and I don’t always have time for that. Which is why I love making a single serving in a coffee mug.

Tips for making Chocolate Lava Mug Cake:

  • Do not over cook! You want to make sure you have a nice gooey center. My sweet spot is 1 minute and 15 seconds to get the perfect lava cake. Start by microwaving for a minute and check your cake.
  • Go crazy and add caramel, nuts, fruit preserves or peanut butter to the center!
  • Dust the top with powdered sugar or vanilla ice cream.
