  • 2 tablespoons gluten-free flour blend
  • 2 tablespoons cocoa powder
  • 2 tablespoons stevia
  • ¼ teaspoon baking soda
  • ¼ cup Greek yoghurt
  • 1 teaspoon milk chocolate chips
  • 1 teaspoon crushed up graham crackers
  • 2 jumbo marshmallows chopped into small pieces


  • In a small bowl, mix together the flour, cocoa powder, stevia and baking soda. Stir in the Greek yoghurt and scoop into a lightly greased ramekin or mug. Place in the microwave and cook for 60 seconds. 
  • Remove from the microwave and top with the chocolate chips and graham cracker crumbs. Sprinkle over the chopped marshmallow and blast with a kitchen blowtorch until golden brown. Alternatively, place under the grill for 2 minutes to toast the marshmallows.


This healthy mug cake is low FODMAP and suitable for most IBS diets as long as you can handle Greek yoghurt, which is low in lactose. There is lactose in the milk chocolate chips and gluten in the graham cracker crumbs. But the quantities are so small that it shouldn't cause any IBS symptoms.
