These keto butter cookies are buttery, crispy on the outside, and loaded with delicious vanilla flavors. Made with basic ingredients, these sugar-free cookies melt-in-your-mouth and are perfect for the festive season.
Preheat your oven: Preheat your oven to 180°C/350°F and line a baking sheet with parchment paper.
Mix the wet ingredients: In a bowl, combine softened butter, egg yolk, vanilla extract, and powdered sweetener. Stir for about a minute until it's smooth and fluffy.
Add dry ingredients: Mix in almond and coconut flour and xanthan gum until well blended. Taste the dough and adjust the sweetener if needed.
Prepare the dough: Place the cookie dough into a piping bag. Pipe the dough onto a baking sheet lined with parchment paper. Please don't make them too flat; leave some space as they'll spread during baking.
Bake: Pop them in the oven for 10-12 minutes or until lightly browned on top.
Cool down: Let the cookies cool completely. They're fragile when hot but will become crispy as they cool.
