Low-FODMAP Five Minute Chocolate Mug Cake; Gluten-free, Dairy-free

Printer Friendly Version

Mug cakes became a tradition in our home when my children demanded cake late in the evenings, and I didn’t want to reach for the preservative-laden snacks in the pantry.  I suddenly realized how easy it could be to make a personal sized cake that would be ready in the microwave in 5 minutes.  Naturally, I had to create a low-FODMAP chocolate mug cake for my own enjoyment!

This low-FODMAP chocolate mug cake is delicious, moist and satisfies your chocolate cravings.  It is gluten-free and dairy-free and can be modified to add peanuts, pecans, almonds or chocolate chips!

  • 1 tablespoon unsweetened cocoa
  • 1/8 tsp xanthan gum if not added to your flour
  • 1/8 teaspoon baking powder

  • 2 tablespoons whisked egg (one large egg is about 3.25 tablespoons)

  • 1/4 teaspoon vanilla

    • 10 g chocolate chips (I usually just toss these on top before baking)
