- 15 oz chocolate cake mix: The foundation of the cookies, it gives them chocolatey richness and keeps them soft.
- 2 eggs: Helps bind the ingredients and adds moisture for a tender bite.

- Peanut butter pieces: These little chunks provide a salty, nutty contrast that perfectly complements the chocolate.
How to Make Chocolate Peanut Butter Cake Mix Cookies Recipe
Step 1: Preheat the Oven
Start by setting your oven to 350 degrees Fahrenheit. This temperature ensures the cookies bake evenly and develop a beautiful golden-brown color that hints at their deliciousness inside.
Step 2: Mix the Wet Ingredients with the Cake Mix
In a mixing bowl, combine the eggs, oil, and softened butter with the chocolate cake mix. For quick and thorough blending, using a hand blender is a fantastic trick that saves you time and gives the dough a smooth consistency.
Step 3: Portion the Dough
With a small scoop or tablespoon, portion out cookie dough balls onto a parchment paper-lined baking tray. This ensures easy cleanup and prevents sticking, so your cookies keep their perfect shape.
Step 4: Flatten and Add Peanut Butter Pieces
Before baking, wet your fingers slightly and gently press each dough ball down to flatten into a cookie shape. Then, press as many peanut butter pieces as you like onto the tops—this part is what brings that extra burst of peanut butter flavor and fun texture.
Step 5: Bake the Cookies
Pop the tray in the oven for 8 to 10 minutes, keeping an eye on them so they turn golden brown but don’t overbake. This short bake time leaves them soft in the center, just how you want a perfect cookie.
Step 6: Cool and Transfer
Once baked, let the cookies cool on the pan for a couple of minutes. This allows them to set and prevents them from breaking when you transfer them to a cooling rack to finish cooling completely.
How to Serve Chocolate Peanut Butter Cake Mix Cookies Recipe
Garnishes
Sprinkle a pinch of flaky sea salt on the warm cookies just before serving to enhance the chocolate and peanut butter flavors—a tiny touch that creates a delicious sweet-salty balance. You can also add a drizzle of melted chocolate or a light dusting of powdered sugar for an extra pretty finish.
Side Dishes
Chocolate Peanut Butter Cake Mix Cookies Recipe pairs wonderfully with a cold glass of milk or a scoop of vanilla ice cream for a decadent dessert experience. For a daytime treat, enjoy them alongside a cup of freshly brewed coffee or hot cocoa to complement the rich chocolate notes.
Creative Ways to Present
Want to impress your guests? Serve the cookies stacked and tied with a rustic ribbon for a charming gift. Alternatively, sandwich two cookies with creamy peanut butter or chocolate spread in between for delightful cookie sandwiches that look as good as they taste.
Make Ahead and Storage
Storing Leftovers
Place any leftover cookies in an airtight container at room temperature. They will stay soft and delicious for up to 5 days, making them perfect for enjoying well after your initial baking spree.
Freezing
If you want to keep these Chocolate Peanut Butter Cake Mix Cookies Recipe treats longer, freeze the unbaked cookie dough balls on a parchment-lined tray, then transfer them into a freezer bag once solid. When you’re ready, bake them straight from frozen—just add a minute or two to the baking time.
Reheating
Warm leftover cookies for about 10-15 seconds in the microwave to revive that fresh-baked softness. Be careful not to overheat, or the peanut butter pieces may become too melty.

Softened butter at room temperature works best as it blends smoothly with the other ingredients, creating a tender cookie crumb without greasiness.

What is the best way to flatten the cookies without making a mess?
Wet your fingertips lightly with water and gently press down on each dough ball. Keeping your fingers damp prevents sticking while allowing you to achieve just the right thickness.
