Preheat the oven to 350°F. Lightly spray a half baking sheet with oil or line with parchment.
Blend the prunes with hot water in a small food processor or blender until a thick paste forms.
Place the puree in a medium mixing bowl. Stir in the oats, brown sugar, almond butter, cinnamon, and salt until a dough forms. Use a tablespoon measure to scoop the dough, roll, then flatten 12 small cookies and place on the prepared baking sheet.
Bake at 350°F for about 12 minutes or until the cookies are lightly brown on the bottom and fragrant. Enjoy warm or let cool on a cooling rack before transferring to a sealed container for up to 3 days.
Notes
Tips for success
Use fresh, plump prunes. Prunes are a pantry staple and have a long shelf life. But if yours have been hanging out a little too long and have started to dry out, the cookie dough will not easily come together.Do not over bake. These cookies are not like flour ones. They won't brown the same and can easily dry out. Stick to the 10-12 minute cook time.
