Plus, whether you opt for gluten-free or regular flour, the taste remains equally delightful.

Ingredients in Healthy Gluten Free Lemon Bars
- Gluten-free flour or regular flour
- 4 oz unsalted butter – Unsalted butter is best because the amount of salt in salted butter varies by brand. It’s best to add the salt separately. If all you have is salted butter, just omit the salt in the recipe.
- 4 oz avocado oil – reduces the butter content and thereby the saturated fat.
- Powdered sweetener – For zero calories, use powdered monk fruit sweetener.
- Granulated sweetener – Again, for zero calories, use monk fruit sweetener.
- Eggs – 2
- Lemon rind
- Lemon juice – fresh, not from a bottle. Always use fresh lemons.
- Salt – brings out the flavor of the other ingredients.
