End the night with one of the easiest lava desserts ever. This one-mug wonder combines the richness of a classic red velvet cake with the melt-in-your-mouthness of a soufflé.

  • 4 tablespoons all-purpose flour
  • 2 tablespoons sugar
  • 1/2 tablespoon unsweetened cocoa powder
  • 1/8 teaspoon baking soda
  • 2 tablespoons buttermilk
  • 1 tablespoon fat-free milk
  • 1/2 tablespoon vegetable oil
  • 1/8 teaspoon white vinegar
  • A few drops red food coloring
  • 2 chocolate truffle balls

Steps to Make It

  1. Combine all ingredients except the truffles into a large microwave-safe mug. Whisk until the batter is completely smooth. If you’d like a darker red color, you can add more food coloring and mix again again. ​

  2. Press the chocolate truffle balls into the center of the cake batter. Make sure the balls are completely covered.

  3. Microwave the cake on medium high for about 50 to 60 seconds. Microwave strengths vary, but you're looking for it to rise and feel springy to touch. It should also pull away from the sides a bit.
