What You’ll Need for Peanut Butter Cookies
Let’s keep it simple. This recipe is what I pull out when friends say they’re stopping by and I don’t have time to fuss. Four ingredients, no fancy tools, and minimal cleanup. You’ll love how the cake mix makes the cookies soft, fluffy, and consistent every time.
- Yellow cake mix or white cake mix works great. Yellow tends to give a richer flavor.
- Creamy peanut butter. Natural peanut butter can work, but I get the best texture from regular creamy.
- Eggs. These bind everything and add moisture.
- Vegetable oil or melted butter. Oil gives a softer cookie, butter adds flavor. Your call.
To make the dough, stir the cake mix, peanut butter, eggs, and oil in a bowl until just combined. The dough will be thick and a little sticky, which is exactly what you want. Scoop into balls, gently press with a fork for a crisscross pattern if you’re feeling classic, then bake at 350 degrees for 8 to 10 minutes. Let them cool on the sheet for a couple minutes so they set up. That’s it.

Can Peanut Butter Cookies Be Frozen?
Absolutely. Freezing is one of the reasons I make these so often. You can freeze the dough or the baked cookies, and both methods turn out great.
To freeze the dough, scoop it into balls and place them on a parchment-lined sheet. Freeze until firm, then tuck them into a zip-top bag. Bake straight from the freezer at 350 degrees, adding a minute or two to the time. To freeze baked cookies, let them cool completely, layer them with parchment in a container, and freeze for up to 3 months. They thaw in about 15 minutes, or you can warm them in the oven for a couple minutes for that fresh-baked feel.
I like keeping a batch of frozen cookie dough balls for last-minute cravings. It’s like personal dessert insurance. If you’re stocking a dessert stash, you might also enjoy these seasonal-friendly Christmas butter cookies.
Tips for Making Perfect Peanut Butter Cookies
These are the little details that make your 4-INGREDIENT CAKE MIX PEANUT BUTTER SOFT COOKIES bakery-level. Simple, practical, and easy to remember.
Mixing and Dough Texture
Don’t overmix. Stir just until the dough comes together. If the dough feels too sticky, chill it for 15 minutes. If it’s a touch dry, add a teaspoon of milk. I’m always surprised how a tiny splash can help.
Shaping and Baking
- Use a cookie scoop for even sizes so they bake at the same pace.
- For classic look and texture, press a fork lightly on top in a crisscross pattern.
- Pull them out when the edges look set but the centers still look soft. They’ll finish on the hot pan.
- Let them rest on the baking sheet for 2 minutes before moving to a rack.
Serving and Storing
Store in an airtight container at room temp for 3 to 4 days with a small piece of bread or a marshmallow to keep them soft. If you want to turn them into dessert sandwiches, spread a little jam or chocolate spread between two cookies. Instant upgrade.
I made these for a last-minute potluck, and people would not stop asking for the recipe. Soft, peanut buttery, and gone in 10 minutes. I loved that they were so easy. It felt like a baking win without the stress.

Variations of Peanut Butter Cookies
Once you master the base, have fun with it. The cake-mix shortcut makes these incredibly adaptable. Here are some of my go-to twists when I’m in the mood to change things up.
Chocolate chip peanut butter: Fold in a cup of chocolate chips. Semi-sweet keeps the sweetness balanced.
Peanut butter cup surprise: Press a mini peanut butter cup into each cookie right after baking. This is a crowd pleaser every time.
Peanut butter and jam bites: Make a thumbprint in each dough ball and fill with your favorite jam after baking. Strawberry or raspberry is classic.
Salted peanut crunch: Add a handful of chopped salted peanuts to the dough and finish with a pinch of flaky salt. Sweet and salty magic.
Double chocolate peanut butter: Use chocolate cake mix with the same ingredients. It turns into a brownie-meets-cookie situation that’s ridiculously good. If you like that vibe, you’ll also love this Reeses peanut butter chocolate brownie idea for weekends.

Frequently Asked Questions About Peanut Butter Cookies
I get these questions a lot, especially from friends who think baking has to be complicated. It really doesn’t. Here’s what you need to know to make your 4-INGREDIENT CAKE MIX PEANUT BUTTER SOFT COOKIES foolproof.
Can I use chunky peanut butter? Yes, as long as you don’t mind the extra crunch. I love it for texture. If your peanut butter is very oily, give it a good stir first.
Do I have to chill the dough? Not required, but 10 to 15 minutes in the fridge helps if the dough feels sticky or if your kitchen is warm.
How do I keep them soft for days? Store them in an airtight container with a small piece of bread or a marshmallow. Replace after a day or two if needed. It works wonders.
Can I add cocoa for chocolate flavor? You can add a tablespoon of cocoa to the mix, but using chocolate cake mix is easier and gives a deeper chocolate taste.
What if I want them bigger? Go for it. Just bake a little longer and keep an eye on the edges so they don’t overbake.
Common Questions
How many cookies does this make? Usually about 20 to 24 cookies, depending on your scoop size. If you go mini, you could stretch it to 30.
Can I add vanilla extract? Sure. A teaspoon adds warmth to the flavor. It’s optional, but I love it.
What if I want them less sweet? Use white cake mix instead of yellow, and add a pinch of salt to balance the sweetness.
Can I make them dairy free? Yes. Use oil instead of butter and double check your cake mix is dairy free.
Do these work as ice cream sandwiches? Absolutely. Freeze the baked cookies first so they stay sturdy, then sandwich with vanilla or chocolate ice cream. It’s a hit every time.
