🥘 Ingredients
Boxed Yellow Cake Mix- Truthfully, you can use any flavor cake mix here, but for a stronger peanut butter flavor, using yellow cake mix would work best (plus it gives us a golden peanut butter cookie color).
Peanut Butter- You can use creamy or crunchy depending on what you have on hand but note that the natural peanut butter won't work nearly as well as simpler brands like Jif and Skippy.
Eggs- These are the binder in the dough, preventing your cookies from becoming too crumbly.
Vegetable Oil- Adding in oils will give your cookies the necessary fats to stay moist. Melted butter could be used instead if desired.

🍴 Recipe Tips
A traditional look
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, rotate it about 90 degrees, and press down to create lines 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 ¼ inch thick at a minimum!
📖 Variations
Making peanut butter cookies using cake mix is so simple and easy but can also be entirely 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!
💭 FAQs
If properly stored in an airtight container, these cookies can last for about 3-5 days at room temperature.
Yes, these cookies freeze very well. Simply place them in an airtight container or Ziploc baggie in the freezer for up to 3 months. Thaw on the counter before eating.
Yes, you can use crunchy peanut butter or creamy peanut butter, whichever you prefer. I do not recommend natural oil peanut butter or alternative nut butts, though, as they have different consistencies and may not turn out as well.
