Ingredients

• 2 cups Almond flour
• 2 tablespoons Coconut flour
• 1.5 cups Powdered erythritol (or preferred keto-friendly sweetener)
• 0.5 cups Unsalted butter, melted
• 4 large Eggs
• 0.75 cups Fresh lemon juice
• 1 tablespoon Lemon zest
• 1 teaspoon Vanilla extract
• 1 teaspoon Baking powder
• 0.25 teaspoons Sea salt
• 0.5 cups Coconut cream (optional, for garnish)

Directions

Step 1

Preheat your oven to 350°F (175°C). Line an 8x8-inch baking dish with parchment paper, ensuring the edges extend over the sides for easy removal.

Step 2

In a medium mixing bowl, combine almond flour, coconut flour, 1/2 cup of powdered erythritol, and sea salt. Mix well to combine.

Step 3

Pour the melted butter into the dry ingredients and mix until a crumbly dough forms. Press this dough evenly into the bottom of the prepared baking dish to form the crust.

Step 4

Bake the crust in the preheated oven for 10 minutes or until lightly golden. Remove and allow to cool slightly while preparing the filling.

Step 5

In a large bowl, whisk together eggs, the remaining 1 cup of powdered erythritol, fresh lemon juice, lemon zest, vanilla extract, and baking powder until fully combined.

Step 6

Pour the lemon mixture over the pre-baked crust and spread evenly with a spatula.

Step 7

Return the baking dish to the oven and bake for 15-20 minutes or until the filling is set and slightly firm to the touch.

Step 8

Remove from the oven and let the lemon slice cool completely before transferring it to the refrigerator for at least 1 hour to chill and fully set.

Step 9

Once chilled, carefully lift the lemon slice out of the baking dish using the parchment paper edges. Slice into 12 squares or bars.

Step 10

Optional: Garnish with a dollop of coconut cream and additional lemon zest before serving.
