Ingredients

For the shortbread crust

2 cups almond flour
3 tablespoons allulose
1 large egg

For the lemon filling

2/3 cup lemon juice
6 large eggs
2/3 cup allulose
1 teaspoon lemon zest

Instructions

Preheat oven to 180C/350F. Line an 8 x 8-inch pan with parchment paper and set aside.
In a mixing bowl, combine your almond flour, allulose and egg, and mix well. Transfer the mixture into the lined pan and press into place.
Bake the shortbread crust for 15 minutes, or until golden. While it is baking, prepare your lemon filling.
In a separate mixing bowl, whisk together the eggs until no whites remain. Add the lemon juice, allulose, and lemon zest and whisk until combined.
Remove the shortbread crust from the oven. Moving quickly, add the lemon filling and smooth it out evenly.
Bake for 20-22 minutes, or until the center is firm but still jiggles slightly.
Remove from the oven and let cool in the pan completely, before refrigerating for at least 2 hours, to firm up more.

Notes

Tips: See my recipe tips above for perfect keto lemon bars.
Sweeteners: Please don't substitute allulose- it's the only sweetener I tried that didn't leave the filling gritty or the shortbread crust crumbly.
Leftovers: Keep in the fridge for up to two weeks or the freezer for up to 6 months.
