Preheat oven to 162ºC. Lightly grease a non-stick muffin pan.

In a large bowl, whisk together almond flour, powdered sweetener, salt, and xanthan gum.
03 -
Stir in the egg and melted butter until a dough forms. Divide dough into two equal portions.
04 -
Lightly dust a work surface with almond flour. Transfer one portion of dough, cover with parchment, and roll to an even 3 mm thickness.
05 -
Cut 9 cm circles using a cookie cutter or drinking glass. Use an offset spatula to carefully lift each crust.
06 -
Press each crust gently into muffin cups, patching any cracks with extra dough. Repeat with remaining dough and re-roll scraps to obtain 12 crusts.
07 -
Bake crusts for 12 minutes, then remove and allow to cool completely to firm up.
08 -
In a medium saucepan over medium heat, combine butter and both sweeteners. Bring to a boil and cook for 3 to 5 minutes, stirring frequently to prevent burning.
09 -
Remove from heat. Stir in heavy cream and caramel extract (mixture will bubble vigorously). Sprinkle xanthan gum over the surface and whisk vigorously. Add salt and combine.

Allow filling to cool to lukewarm, about 10 minutes, then whisk in the egg until smooth.

Divide chopped raisins or nuts evenly among tart shells. Spoon filling into each crust, filling almost to the top.

Bake for 15 to 20 minutes until edges are golden and filling is mostly set but slightly jiggly in the center.

Remove from oven and allow to cool completely before loosening each tart with a knife.
