In a mixing bowl, combine the eggs, oil and peanut butter until well combined.
Add the cake mix until completely combined.
Chill the dough for 30 minutes.
Using a small cookie scoop or a tablespoon, place the cookies on a parchment lined baking sheet.
Using a fork, slightly floured, press the fork into each cookie to form the "cross hatch" design.
Sprinkle a little of the sugar on the top of each cookie if desired.
Bake in a 350 preheated degree oven for 10 minutes or just until they are slightly browned.
Remove from the baking sheet to cool.
Serve with a glass of cold milk because cookies need a glass of milk!
Notes
The extra granulated sugar sprinkled on top of each cookie before baking gives the cookies a nice added crunch.Store the cookies in an airtight container at room temperature. They should stay soft and chewy for up to 3 days.You can also flash freeze them on a baking tray for 60 minutes. Then place them in a freezer-safe container or bag. They'll stay good in the freezer for up to 2-3 months.
