Thin and crispy with a bit of chew, these buttery cookies feature toasted pecan flavor. The allulose allows for some spread and the monk fruit gives them a bit of a crisp.
Preheat the oven to 375ºF and line a rimmed baking sheet with parchment paper.
Combine almond flour, lupin flour, gelatin, sugar, and salt in a bowl. Mix softened butter, egg yolk, milk, and vanilla in thoroughly using a fork.
Form dough into balls the size of a small walnut. Place on a parchment-lined baking sheet. Press 1/16th of an inch thick with the bottom of a greased glass dipped in granulated monk fruit. Lightly beat the egg white and use it to brush the tops of the pressed cookies before sprinkling with pecans.
