Preheat the oven to 350 degrees and line a sheet tray with parchment paper.
In a large bowl, mix the erythritol and butter until light and fluffy. Use a stand mixer with a paddle attachment or a hand mixer to make sure the mix is very light.
Add the eggs one at a time, mixing after each addition.
Add the vanilla and mix again.
Add the salt and almond flour and gently fold into the mix until smooth.
Scoop the cookie dough onto the prepared tray, making scoops that are about 2 tablespoons in size.
Gently press down on the cookie dough balls to flatten slightly by using a fork. This will also make a nice pattern on the top of your cookie.
Bake the cookies for about 15-17 minutes or until the edges just begin to turn golden brown.
Remove the cookies from the oven and move them to a cooling rack to cool.
