    How to Make Keto Lemon Bars – Step by Step

     

    Preparing the Crust

     

    1. Preheat your oven: Start by preheating your oven to 350°F (175°C).
    2. Mix ingredients for the crust: In a medium bowl, combine the almond flour, erythritol, and melted butter. Stir until they form a crumbly dough.
    3. Form the crust: Press this dough evenly into the bottom of an 8×8 inch baking dish lined with parchment paper. This makes it easier to remove the bars after baking.

    4. Blend the filling ingredients: In another bowl, whisk together the eggs, lemon juice, lemon zest, salt, and baking powder until smooth.
    5. Combine: Pour this lemon mixture evenly over the prepared crust in the baking dish.

    7. Cool: Remove from the oven and allow to cool to room temperature. Then, refrigerate for at least an hour before cutting into squares.
    8. Garnish and serve: Prior to serving, garnish with additional lemon zest if desired for that extra citrus punch.
