Preheat oven to 350F. Stir flour with baking soda and salt in a medium sized bowl. Whisk almond butter with oil in a large bowl, then whisk in the brown sugar until creamy (about 1 min)
Using a wooden spoon, beat in the egg, egg yolk and vanilla. Gradually stir in flour misture until just combined.
Scoop about 1 tbsp of the dough and roll it into a ball. Place on a large baking sheet. Repeat, keepin the cookies approximately 2 in apart.
Bake in center of the oven for 3 mins. Remove from oven. Dip a fork into the granulated sugar and press a criss cross pattern on each cookie ball. Continue baking for 8 more mins.
Transfer sheet to a rack and let cool for 2 mins. Cookies will look undercooked but will continue to bake on the hot sheet as they sit. Transfer the cookies to a rack to cool completely, and continue with the next batch with the cooled cookie sheet.
