End the night with a bang, a.k.a. the easiest lava dessert ever. This one-mug wonder combines the richness of a classic red velvet cake with the melt-in-your-mouthness of a soufflé. All it takes is a few ingredients — including truffles for a warm chocolate-caramel center — a whisk, your favorite mug, and a minute in the microwave.   

What You'll Need

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

How to Make It

  1.  Combine all  ingredients except the truffles into a large microwave-safe mug. Whisk until batter is completely smooth. If you’d like a darker red color, you can add more food coloring now and mix well again. ​
  2. Press the chocolate truffle balls into the center of the cake batter. Make sure the balls are completely covered with cake batter. 
  3. Cook the cake on medium high for about 50-60 seconds. Microwaves vary but you are looking for it to rise and feel springy to touch. It should also pull away from the sides a bit.
