Preheat oven to 325

Line a baking sheet with parchments paper or a silicone liner.

In a large mixing bowl add nut butter, sweet potatoes, vanilla, and chocolate syrup.

Whisk together to mix well.

In a small mixing bowl combine flour, sugar, cocoa powder, baking soda, and salt.

Add flour mixture to sweet potato mixture and stir to combine.

Stir in chocolate chips and mini M&Ms.

Using a small cookie scoop, place mounds of dough on prepared cookie sheet. Gently press mounds to slightly flatten. I flatten the cookies to about half the size.

Add a few M&Ms on top if desired and bake for 10-12 minutes.

Remove cookies from the oven and let them sit for 3-5 minutes, as they will be fragile until cooled.

Move to a cooling rack to reach room temperature.
