How to make Keto Lemon Curd Tart
Ingredients:
- 1 recipe Almond Flour Pie Crust
- 3 large eggs
- 6 tbsp powdered Swerve Sweetener
- 2 tbsp BochaSweet or allulose
- 1/4 cup freshly squeezed lemon juice
- 2 tsp lemon zest
- 4 tbsp butter, cut into 4 pieces
- 12 ounces mascarpone cheese (or cream cheese), softened
- 1/4 cup powdered Swerve Sweetener
- 2 tsp lemon zest
- 1/2 tsp lemon extract
- 1/2 cup lemon curd
Directions:
Preheat the oven to 325°F and lightly grease a 10-inch ceramic tart pan. Prepare the crust with the almond flour, pressing it firmly into the bottom and sides of the pan. Prick all over with a fork and bake for 15 to 20 minutes, until golden brown. Let cool completely. While the crust is baking, let’s bring the lemon curd to life! In a glass or ceramic bowl set over a pan of barely simmering water, whisk together the eggs, sweeteners, lemon juice, and lemon zest for about 10 minutes until thickened. Remove from heat, add butter, and whisk until velvety smooth. Let cool for at least 15 minutes.
In a large bowl, beat together the mascarpone and the powdered sweetener until creamy and delightful. Mix in lemon zest and lemon extract, then gently fold in a generous 1/2 cup of the cooled lemon curd. Spread this luscious filling into the cooled crust. Now, freeze for 1 hour to set the magic in motion. Once firm, spread the remaining lemon curd over the filling and chill for another 3 hours to set—your patience will be rewarded!
When it’s time to serve, cut the tart into wedges as you garnished it with the cheeky zest of extra lemon or perhaps a handful of fresh berries. And remember, this tart doesn’t just taste good; it looks stunning too—perfect for impressing your friends at any gathering or just treating yourself!
