Line a baking sheet with a non stick silicone mat or greased parchment paper. I find the silicone mat works the best.
In a medium bowl with hand mixer add egg whites and beat on medium low speed for 1 minutes. Egg whites should be white and frothy.
Continue mixing at medium speed add 1 Tablespoon of erythritol at a time, after all of the erythritol add 1 Tablespoon of powdered erythritol at a time, continue whisking together until stiff peaks form. Batter should be glossy and smooth.Stir in vanilla extract.
Spoon meringue batter into mounds on prepared baking sheet or spoon into a piping bag and pipe into little mounds.
Bake 2.5 -3 hours or until meringues are hardened on the outside and lift off the parchment paper with bottoms intact and centers are not sticky inside. Turn off the oven and allow them to cool inside the oven.
Store in an airtight container for up to 2 weeks.
