Prep: Preheat oven to 375°F. Line a baking sheet with parchment paper and set aside. Also measure the 2 TBSP of sugar into a small bowl, set that aside as well.
Cookie dough: Beat half the cake mix, water, peanut butter and eggs with an electric mixer, in a large bowl, until smooth. Then stir in the remaining cake mix until it's just incorporated.
Scoop 1 TBSP portions of dough onto the prepared baking sheets. Use a wet fork dipped in the sugar to create crisscross patterns on each ball of cookie dough, dipping in sugar again after each cookie.
Bake: Place the cookies in the preheated oven and bake for 9-10 minutes. Let the cookies cool for a few minutes, then transfer to a baking rack. Serve & enjoy!

They can also be refrigerated to extend their shelf life.For longer storage, freezing is an option; just ensure they are well-wrapped to prevent freezer burn. They will be good for up to 3 months if stored properly.
