¼cupfat-free sugar-free yogurt(use lactose-free yoghurt for low FODMAP or non-dairy alternative for vegan)
Stir all the ingredients together in a mug or ramekin that holds at least 6oz (these ramekins are perfect) until totally combined. Make sure there are no dry pockets left.
Place in the microwave and cook on full power for 45 seconds, until the outside of the brownie is springy to the touch but the centre is still a little wet. Enjoy straight away while warm.
You can top your brownie with chocolate chips straight after it comes out the microwave. They'll melt and get wonderfully gooey after about 30 seconds. But 1 tablespoon of chocolate chips will also add 60 calories. It's your call!If you're making this healthy mug brownie on a low FODMAP diet, you need to be careful about the artificial sweetener, since most IBS sufferers struggle with them. You can replace the sweetener with 2 tablespoons of sugar, but this will add 100 calories.
