    Zesty Keto Lemon Bars

    Sugar-Free Lemon Bars

    I always bake with chocolate most of the time, but today, I am in a mood to try something new, something refreshing. So, I have made these keto-friendly lemon bars with almond flour and fresh lemon juice. They are so creamy and tasty.

    The creamy texture and zesty flavour of this treat are irresistible! If you are a big fan of lemon desserts like me, I guarantee that you will love these low-carb lemon bars. The trick is to use fresh lemon juice!

    These are my favourite summer treat ever; they are so refreshing, delicious and easy to make and made with only 5 ingredients!

    Without further ado, let me tell you how I made these delicious low-carb lemon bars.

    Keto Lemon Bars Ingredients

    Crust Ingredients.

    For the crust I used:

    Almond flour, melted butter, and 2 tablespoons of powdered erythritol. You may use your favorite powdered sweetener, Swerve, Stevia or Monk Fruit.

    Pro Tip: To make the crust dairy-free, use coconut oil instead of butter.

    filling Ingredients.

    For the filling I used:

    Eggs: 3 large eggs.

    Lemon juice and zest: To give my bars that zesty, lemony flavour.

    Powdered erythritol: To sweeten the filling.

    Pro Tip: I highly recommend using powdered sweetener because I tried these bars with granulated sweetener, and the bars turned out so grainy and not as smooth as I like.

    Here is my trick when I don't have powdered sweetener on hand, I just grind some granulated sweetener in the grinder until fine.

    Almond flour: NOT almond meal. Almond flour has a fine texture.

    How to Make Keto Lemon Bars?

    One (Make The Crust): Preheat the oven to 180C / 350F. Grease 20x30cm baking dish with butter.

    Two: In a bowl, add the almond flour, powdered erythritol and butter, mix well until combine.

    Three: Spread the mixture equally in the baking dish while pressing on it with your hand to flatten it.

    Four: Bake for 10-15 minutes or until golden brown. Leave it to cool while you make the filling.

    Five (Make The Filling): In a medium-sized bowl, whisk the eggs using an electric hand mixer until fluffy, add powdered erythritol, lemon juice and lemon zest whisk again until combined.

    Six: Add the almond flour, whisk until well incorporated.

    Seven: Pour the filling over the crust and bake for 14-15 minutes. Leave it to cool down then sprinkle some powdered erythritol on top. Slice and serve.

    Note: These bars are delicious, topped with fresh fruit like strawberries.

    Storage

    To store: Keep these bars in the fridge for 2-3 days or in the freezer for 1-2 months. However, you need to separate the bars with parchment paper so they don't stick to each other while freezing.
