I love how this recipe simplifies cookie baking without sacrificing flavor. It’s perfect for those moments when I crave something sweet but don’t want to deal with measuring out flour and sugar.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 box yellow cake mix (15.25 oz)

1 cup peanut butter (smooth or crunchy)

2 large eggs

1/3 cup vegetable oil

1/2 tsp vanilla extract (optional)

Pinch of salt (if using unsalted peanut butter)

Optional: 1/2 cup chocolate chips or chopped peanuts

Directions

I start by preheating the oven to 350°F (175°C) and lining a baking sheet with parchment paper.

In a large mixing bowl, I combine the cake mix, peanut butter, eggs, oil, and vanilla (if I’m using it). I stir everything together until it forms a thick dough.

If I’m adding chocolate chips or peanuts, I fold them in at this point.

I scoop out tablespoon-sized portions of dough, roll them into balls, and space them out on the prepared baking sheet about 2 inches apart.

Using a fork, I flatten each dough ball slightly in a crisscross pattern.

I bake the cookies for 9 to 11 minutes, just until the edges are set and lightly golden.

After baking, I let them cool on the sheet for about 5 minutes before transferring them to a wire rack to cool completely.

Variations

When I want to mix things up, I try some of these simple variations:

Add chocolate chips for a peanut butter-chocolate combo.

Use crunchy peanut butter to add extra texture.

Mix in chopped peanuts for a nutty crunch.

Drizzle with melted chocolate once cooled for a decorative and tasty finish.

Try different cake mix flavors like chocolate or spice for a twist on the classic.

Storage/Reheating

I store these cookies in an airtight container at room temperature for up to 5 days. They stay soft and chewy the whole time. If I want to keep them longer, I freeze them in a single layer in a freezer-safe bag or container. To enjoy later, I let them thaw at room temperature or give them a quick 10-second warm-up in the microwave to revive that fresh-from-the-oven softness.

FAQs

How do I know when the cookies are done?

I look for lightly golden edges and a slightly soft center. They’ll continue to firm up as they cool, so I avoid overbaking them.

Can I use a different type of cake mix?

Yes, I’ve used chocolate or even spice cake mix for a fun twist. The texture remains great, and it adds a new flavor profile.

Can I make these cookies gluten-free?

Absolutely. I just swap in a gluten-free yellow cake mix. It works just as well and keeps the recipe safe for those with gluten sensitivities.

Do I need to chill the dough?

No chilling is required, which is one reason I love this recipe. I can go straight from mixing to baking without waiting.

Can I double the recipe?

Yes, I double the ingredients for a bigger batch. It scales up perfectly, making it great for parties or gifting.
