These unforgettable gluten-free lemon bars will leave an impression I promise. Each bite tastes like a sip of lemonade, which was a pleasant surprise for someone who eats mostly dark chocolate treats.

The texture is not cake like or chewy like a brownie, it’s honestly best described as dreamy.

To Make These Gluten-Free Lemon Bars You Will Need These Ingredients:

  • Gluten-free flour baking blend that includes Xanthan gum or guar gum ~ guar gum for Low FODMAP
  • Sugar ~ granulated or beet
  • Salt
  • Eggs
  • Butter or a dairy-free substitute ~ I haven’t tried this recipe with a dairy-free substitute, but I have found sometimes in some recipes, a little less is needed. Some types of dairy-free butter can be watery when heated.
  • Fresh lemon juice
  • Lemon zest
  • Powdered sugar
  • Sprinkles for fun to add some color ~ optional

For best results, store lemon bars in the refrigerator or freeze them for longer storage.

Another easy and delicious lemon dessert is Mom’s Lemonade Pie.

If you don’t have a square baking pan, I would definitely consider investing in a couple. You may find you use them more than any other baking pan…not counting cookie sheets.

I prefer baking pans with raised lids, so frosting and decorations aren’t smashed from the saran wrap or foil. I personally don’t worry about non-stick-coated pans because I always line them with parchment paper to prevent sticking.

Enjoy the Lemon Bars!   Yum
