Ingredients You’ll Need

What makes Cake Mix Peanut Butter Cookies such a weeknight superstar is their short ingredient list—each one is simple but brings something magical to your mixing bowl. Here’s everything you need and exactly why each is essential.

Yellow Cake Mix (13.25 ounces): Gives your cookies an unbeatable fluffy texture and a sweet, buttery baseline without the need for flour or heaps of sugar.
Creamy Peanut Butter (1 cup): Adds that creamy richness and deep peanut flavor, making every bite satisfyingly nutty.
Oil (½ cup): Ensures moist, tender cookies that stay soft for days; vegetable or canola oil works perfectly here.
Large Eggs (2): Binds everything together and gives the cookies just the right chewiness—don’t skip them!

How to Make Cake Mix Peanut Butter Cookies

Step 1: Prep Your Baking Sheets

Before you do anything else, preheat your oven to 350°F. Line three cookie sheets with parchment paper to prevent sticking and make cleanup a dream. Having everything ready means your cookie assembly will be smooth sailing.

Step 2: Mix the Dough

Grab a large bowl and combine the yellow cake mix, creamy peanut butter, oil, and eggs. Take out your electric mixer and blend on medium until everything just comes together. Don’t worry if the dough looks slightly crumbly—it should still feel moist when pressed together in your hands.

Step 3: Scoop and Shape

With a medium cookie scoop (about 1 ½ tablespoons), scoop out portions of dough. Roll each into a smooth ball with your palms. Place them on the prepared baking sheets, leaving a couple inches between each one. For that iconic peanut butter cookie look, gently press a fork onto the top of each ball, making a crisscross pattern.

Step 4: Bake to Perfection

Bake one cookie sheet at a time for 10 to 12 minutes. You’ll know the Cake Mix Peanut Butter Cookies are ready when the edges start to turn golden but the centers still look just a bit soft. Remember, don’t overbake—these cookies will continue to set as they cool.

Step 5: Cool and Enjoy

Once out of the oven, let the cookies rest on their sheet for about 15 minutes. This step is crucial for that slightly crisp edge and fudgy center. They’re ready to eat right after, but truthfully, they’re tough to resist even when still warm!

How to Serve Cake Mix Peanut Butter Cookies

Garnishes

For an irresistible finishing touch, try a light dusting of powdered sugar or add a drizzle of melted chocolate once the cookies have cooled. If you want a salty-sweet contrast, sprinkle a tiny pinch of flaky sea salt on top—the peanut butter flavor will pop even more!

Side Dishes

Pair these cookies with a cold glass of milk, a scoop of vanilla ice cream, or a mug of coffee. If you’re serving a dessert platter, these cookies sit beautifully next to chocolate brownies or fresh berries for a colorful, crowd-pleasing tray.

Creative Ways to Present

Stack them high for a rustic bakery-style presentation, or arrange in a wide-mouthed mason jar tied with ribbon as a sweet homemade gift. For something fun, sandwich a scoop of your favorite ice cream between two Cake Mix Peanut Butter Cookies to make ultra-indulgent cookie sandwiches.

Make Ahead and Storage

Storing Leftovers

Keep your cookies soft and chewy by storing them in an airtight container at room temperature. They’ll stay fresh for up to four days—though, personally, they rarely last that long in my house!

Freezing

Cake Mix Peanut Butter Cookies freeze beautifully. Place completely cooled cookies in a zip-top freezer bag and squeeze out as much air as possible. They’ll keep well in the freezer for up to three months. For fresh-baked flavor, thaw at room temperature before serving.

Reheating

To bring back that just-baked magic, warm a cookie in the microwave for 8-10 seconds. The peanut butter aroma will fill your kitchen, and you’ll get that perfect soft texture all over again.

FAQs

Can I use chunky peanut butter instead of creamy?

Absolutely! Chunky peanut butter will give your Cake Mix Peanut Butter Cookies a little crunch and extra bursts of nutty goodness—just make sure to measure the cup generously so you still get enough peanut flavor throughout.

What’s the best way to prevent cookies from spreading too much?

If you notice your cookies are spreading too much, chill the dough balls for about 10-15 minutes before baking. It helps them hold their shape and results in thicker, chewier cookies.

Can I add mix-ins like chocolate chips?

Yes! Chocolate chips, white chocolate, chopped peanuts, or even mini candies make delicious additions. Stir them in after mixing the dough so every bite has a fun surprise.

Can I use a different cake mix flavor?

You sure can. While yellow cake mix gives a classic base, trying chocolate or even spice cake mix will put a new twist on your Cake Mix Peanut Butter Cookies. Experiment to find your favorite!

How do I know when the cookies are done?

Look for light browning around the edges and centers that are just set but still soft. Remember, the cookies firm up as they cool on the sheet, so it’s better to underbake slightly than to overdo it.

Final Thoughts

If you’re looking for a simple, soul-warming treat that’s guaranteed to impress with minimal effort, Cake Mix Peanut Butter Cookies deliver every single time. Give them a try next time a craving hits—you might just find they become a regular in your baking rotation!
