Preheat the oven to 350 degrees F. Line a cookie sheet with silicone mat, parchment paper or leave ungreased.
In a large bowl, add the peanut butter and sugar and mix until creamy. Stir in the almond milk and vanilla. Next, add the flour, baking soda, and salt, mix to combine. The dough will be tough to stir, using your hands to mix it together will be easier.
Using a 1.5 tablespoon scooper, scoop out the dough and roll into balls, about 1 ¼ inch. Place the balls of dough about 2 ½ inches apart on a baking sheet. Using the back of a fork, flatten in a crisscross pattern. Optionally, sprinkle with sugar or coarse salt.
Place in the oven and bake for 10 – 13 minutes (13 minutes will yield a crispier cookie that’s tender inside). Let cool a few minutes, transfer cookies to wire rack and repeat with remaining dough.
Makes 20 – 24 cookies.
Cookies can be stored in an airtight container on the counter for 5 days. They do well loosely covered on the counter for 2 – 3 days as well. To keep longer, store in the refrigerator for up to 2 weeks.
Let cookies cool completely, store in freezer safe container for up to 2 months.
