Lose Weight By Eating
These Low Calorie Lemon Bars are just 95 calories! They are just as good as the traditional recipe, but for a fraction of the calories.
I used my favorite all-natural zero calorie sugar (both granulated and powdered versions) and I included a link below so you can check them out. But you can use regular granulated sugar and powdered sugar if you prefer.
Special Tip: You can cut the calories and carbs more by cutting the crust in 1/2. Just use 1/2 of the ingredients and pack it in a very thin layer. You'll also want to cut the bake time on the crust to just 8 minutes.
