Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Prepare the Dough: In a bowl, mix together almond flour, egg, softened butter, erythritol, and water until a smooth dough forms.

Roll and Cut the Dough: Roll the dough out on a floured surface into a thin rectangle. Cut into small rectangular pieces, the size of traditional pop tarts.

Add the Jam Filling: Place about 1 teaspoon of your favorite sugar-free jam in the center of each rectangle.

Seal the Pop Tarts: Fold the dough over the jam to create a pocket. Press the edges together to seal, crimping with a fork if needed.

Bake the Pop Tarts: Place on the prepared baking sheet and bake for 12-15 minutes, or until golden brown.

Cool and Glaze: Let them cool on a wire rack before glazing. Mix powdered erythritol with vanilla extract and water to create a glaze, then drizzle over the cooled pop tarts.

Serve: Enjoy your keto-friendly, homemade pop tarts!
