In a medium-size mixing bowl, combine the almond meal, erythritol, vanilla, salt, and butter. Mix until all ingredients are combined and forms a crumble.
Key Lime Cream Filling
In a separate large mixing bowl, combine the cream cheese, heavy cream, powdered erythritol, melted butter, lime zest, and lime juice. Using an electric hand mixer, beat the ingredients until the mixture is whipped smooth and forms a whipped frosting texture (this can take up to 6 minutes).
Add 1 tablespoon crumb to the bottom of 4 (1.5 to 2 ounce) shot glasses or small dessert jars.
Add 2 tablespoon of the key lime cream mixture over the top of the crumb layer in each jar.
Add ½ tablespoon of additional crumb mixture to the top of the key lime cream layer in each jar.
Top that last crumb layer with 2 tbsps Key lime cream mixture in each jar. Serve. Store any unused parfaits in the fridge.
