Preheat and combine: Heat oven to 370°F (188°C). In a mixing bowl, whisk together almond flour and powdered keto sweetener until well blended.
Create the dough: Add vanilla extract and egg whites to the dry ingredients. Mix and knead the mixture until it comes together into a smooth dough.
Form cookies: Shape dough into small balls and arrange on a parchment-lined baking sheet. Gently flatten each ball and use a fork to make decorative ridges on top.
Bake: Place in oven and bake for 10-12 minutes until edges turn golden brown. Remove from oven when done.
Prepare chocolate coating: While cookies cool slightly, melt sugar-free chocolate chips in microwave or double boiler until smooth.Once cookies are cool enough to handle, dip each cookie into the melted chocolate. If using low-carb sprinkles, add them immediately while chocolate is still wet. Let set before serving.
