The base of these gluten-free lemon bars is made with almond flour, monk fruit sweetener, and butter, which is the perfect vessel for the tangy lemon filling.

Eggs, lemon juice, lemon zest, coconut flour, plus more sweetener make the filling, and everything is baked in the oven until set.

Lemon bars are a delicious snack with their tart and sweet flavor, and if you need to eat gluten-free and/or low-carb, they are the ideal choice for you!

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients and equipment needed for this recipe have been linked to Amazon or other stores if available online. Staple ingredients such as oil, salt, sugar, etc., aren’t always included here as you’re likely to have those in your kitchen. The complete list of ALL ingredients with measurements is found on the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
