Tips for making peanut butter cookies using cake mix

This cookie recipe is so simple and easy but can also be quite customizable. For example, if you just swap out the yellow cake mix for another variety you can find yourself with unique combinations. You can even sprinkle sugar on the top before baking for a caramelized top. Yum!

You’ll make the dough by simply mixing the ingredients together and then roll them into balls. A cross-hatch top isn’t necessary, but peanut butter cookies almost always have a crosshatch on top for appearances, making them unique and distinguishable from a distance.

You create the crosshatch by simply using the back of a fork. Press the prongs down on the ball of dough to flatten and leave marks. Lift the fork and rotate it about 90 degrees and press down to create lines going in the opposite direction. Lift and you’re done.

If you don’t want to do crosshatch with a fork, you can cut a small square of wax or parchment paper and lay it over a cookie dough ball. Press down on the dough ball with the bottom of a glass mug and repeat until all cookies have been flattened. Don’t flatten them too much, you still want them 1/4 inch thick at a minimum!
