Heat oven to 350 degrees. Line 2 cookie sheets with silicone or parchment.
Combine cashew butter, eggs, and vanilla in a large mixing bowl.
Add sugar, cocoa powder, baking soda, and salt. Beat until completely mixed together, about 1 minute. Fold in chocolate chips.
Using a tablespoon-sized cookie scoop, drop onto prepared cookie sheets about 2 inches apart.
Bake 8-9 minutes until puffed and crinkled (they will still be soft) and let stand on sheet about 5 minutes before transferring to a rack to cool completely.
*You can also use almond butter or peanut butter, but the flavor will be much more pronounced.**I usually decrease the sugar to 3/4 cup, but they are definitely less sweet, so it's up to you and your family's preference.
