  • Mix together the beef gelatin and boiling water in a small bowl and stir to dissolve; set aside.
  • Cream together the butter, sour cream, Swerve Confectioners, egg, vanilla extract, almond extract, and stevia glycerite in a large bowl and set aside. Beat in the dissolved gelatin.
  • Whisk together the almond flour, coconut flour, and baking powder in a medium bowl.
  • Melt the mozzarella cheese in a microwave (in 30 second increments) or in a double boiler.
  • Add the almond flour and mozzarella cheese to the butter mixture and stir vigorously to combine. It might be helpful to knead the dough a bit with oiled hands to help it come together.
  • Form the dough into a ball, flatten it slightly into a disk, wrap it in plastic wrap, and refrigerate until chilled (about 2 hours in the fridge or 20 minutes in the freezer).
  • Preheat the oven to 350F and line 2 large baking sheets with parchment paper or silpat liners. Roll the cookie dough out between 2 pieces of parchment paper to a circle about ¼-inch thick. Use a cookie cutter in any shape you like to stamp out the dough into cookies, and then gather the scraps, re-roll, and repeat until the dough is all used. I used a 3-inch circle cookie cutter and got 12 cookies.
  • Arrange the cookies on the prepared baking sheets and bake until golden on the bottom, about 12 to 15 minutes, rotating the trays once halfway through. Cool completely before frosting.


  • Add the cream, egg yolks, Swerve Confectioners, stevia glycerite, and salt to a small saucepan over medium heat. Cook until the mixture is thickened, about 3 minutes, whisking constantly. Cool to room temperature and then chill.
  • Use a handheld electric mixer to cream the butter and vanilla together in a large bowl. Beat in the chilled cream mixture until light and fluffy.
  • Frost the cookies; serve.
