Start by preheating your oven to 350°F (175°C).
In a spacious mixing bowl, simply combine the almond flour, powdered sweetener, softened vegan butter, and vanilla extract.
Stir and mix everything together until you have a smooth, pliable dough that's easy to handle.
Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
Scoop about 1 tablespoon of dough for each cookie, then gently roll it into a neat ball. Arrange these dough balls on your lined baking sheet, leaving a little space between each one.
Pop the baking sheet into your preheated oven and bake for 15 minutes, until the cookies are lightly set and just a hint golden.
Once baked, remove the cookies from the oven and let them cool down just enough so you can comfortably handle them.
Pour a generous amount of extra powdered sweetener onto a plate. While the cookies are still warm, gently roll each one in the sweetener until it's beautifully coated like a snowball.
Finally, let the cookies cool completely on a wire rack. For an extra festive, snowy finish, give them one more roll in powdered sweetener before you serve them up!
