Our Low FODMAP Lemon Bars feature a crisp, buttery crust (with a secret) baked to a golden hue, topped with puckery lemon filling. Classic lemon bars made low FODMAP, gluten-free and lactose-free! We love turning traditional desserts into treats that we can all share without triggering our IBS. I made umpteen versions and didn’t rest until I came up with what I think is the absolute best. Bake them and see!Low FODMAP Serving Size Info: Makes 16 bars; 16 servings; serving size 1 bar
