Keto Lemon Bars Ingredients

– Almond flour: Blanched almond flour is what’s needed for the crust. Make sure not to get finely ground almond meal, which has an uneven texture.

– Butter: Unsalted butter is best in this recipe.

– Keto friendly sugar: Erythritol or monk fruit are keto sweeteners. They can be found at many grocery stores, health food stores or online. It’s a sugar alcohol that has zero calories and does not affect blood sugar levels.

– Lemon Juice: Freshly squeezed is best. Since lemon is the star of this recipe I would avoid store bough lemon juice.

– Lemon zest: This is optional but it really kicks up the lemon flavor. I would strongly suggest you use it in this recipe.

– Eggs: Large eggs are used to help the filling bind together.

– Xanthan powder: This is a keto thickening agent that is low carb.

– Salt: Just a pinch I always add salt when baking. It enhances the flavor of whatever I’m baking.
