Gluten-Free Lemon Bars

Lemon Bars
About two years ago, one of my children was diagnosed with celiac disease. This is a wheat allergy, and having a mother who loves to bake makes life especially difficult for her. However, I also love to experiment with foods, so I’ve been developing gluten-free versions of some of our favorite treats.
Lemon Bars
That brings me to this recipe! We think they’re even better than regular lemon bars. The gluten-free flour and corn starch make the crust melt in your mouth. Combine that with the deliciously sweet and tart filling, and it’s fabulous!
