Preheat oven to 350 degrees.

In a bowl whisk the salt and egg together then add the erythritol and stevia until combined well.

Stir in the nut butter of choice and applesauce until completely incorporated.

Using a tablespoon, scoop out batter into mounds on a parchment lined baking sheet. (Should make 20-21 mounds)

Spray the outside bottom of a ¼ teaspoon measuring spoon with nonstick cooking spray and push the bottom into the center of each cookie to create an indent for the jam.

Using the same ¼ teaspoon, spoon jam into each cookie in the indent you made.

Bake for 10 minutes, let cool slightly then transfer to cooling rack.
