Step-by-Step Instructions

Creating these delightful Keto Lemon Bars is straightforward if you follow these easy steps:

  1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line an 8×8 inch baking dish with parchment paper, extending the paper over the edges for easy removal later.
  2. Make the Crust:
  • In a mixing bowl, combine the almond flour, melted butter, erythritol, egg, vanilla extract, and salt.
  • Stir until the mixture forms a crumbly dough.
  1. Press the Crust: Evenly press the dough into the bottom of the prepared baking dish. Use your fingers or the back of a spoon to make it as flat as possible.
  2. Bake the Crust: Place the crust in the preheated oven and bake for about 12-15 minutes until lightly golden. Remove from oven and let cool slightly.
  3. Prepare the Lemon Filling:
  • In a mixing bowl, whisk together the eggs and erythritol until well combined.
  • Add in the fresh lemon juice, zest, almond flour, and baking powder. Mix until smooth and well incorporated.
  1. Pour the Filling: Pour the lemon filling over the pre-baked crust, spreading it evenly.
  2. Bake Again: Return to the oven and bake for an additional 20-25 minutes until the filling is set and slightly firm to the touch.
  3. Cool Down: Remove from the oven and let the bars cool in the baking dish. Once cooled, place them in the refrigerator for at least 15-20 minutes to firm up.
  4. Cut and Serve: Lift the bars out of the dish using the parchment paper and cut into squares.

Following these steps will guide you in creating these incredible Keto Lemon Bars effortlessly.
