Cake Mix Peanut Butter Cookies are a soft and chewy treat that’s quick and easy to make. With just five pantry ingredients, this foolproof recipe is perfect for casual gatherings or sweet snacking. Enjoy them fresh or freeze for later to always have a homemade treat on hand.
Preheat your oven to 350 degrees Fahrenheit. Line a large baking sheet with parchment paper.
Mix Wet Ingredients
In a large mixing bowl, stir together the peanut butter, eggs, and oil until smooth and well combined.
1 cup peanut butter, ½ cup vegetable oil, 2 eggs
Mix Dry Ingredients
In a separate bowl whisk together the cake mix with the baking soda.
15.25 ounces yellow cake mix, 1/2 teaspoon baking soda
Combine Wet and Dry Ingredients
Gradually add the dry cake mix into the bowl with the wet ingredients. Mix until a thick cookie dough forms.
Optional: If you want to add the peanuts and chocolate chips fold them into the mixed dough.
1/2 cup peanuts, 1/2 cup chocolate chips
Shape Dough
Divide the dough into equal portions. I like to use a cookie scoop for this step. Roll each into a ball using your hands and place them on the prepared baking sheet.
Create Classic Peanut Butter Pattern
Use a fork to gently press down on each cookie ball, then turn the fork 90 degrees and press again to create a criss-cross pattern.
Optional: If you have added the peanuts and chocolate chips you can skip pressing with the fork. I would suggest pressing the balls slightly flat when placing them on the cookie sheet.
Bake
Bake for 10 to 15 minutes, or until the cookies are set and the edges begin to turn lightly golden. Do not overbake.
Cool
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Gina’s Quick Tips Before You Get Started
Make sure your eggs are at room temperature for better mixing.
If your coconut oil is solid, briefly heat it in the microwave to liquify.
No mixer required, just a sturdy spoon or spatula will do.
Common Mistakes When Making This Recipe:
Overbaking: Keep an eye on the cookies around the 10-minute mark. They firm up as they cool.
Using natural peanut butter: It can make the dough too oily. Stick with classic creamy or crunchy types.
Storage and Reheating Instructions
Store leftovers in an airtight container on the counter for up to 4 days.
Freeze baked cookies in a zip-top bag for up to 2 months.
No need to reheat, they’re delicious straight from the container or freezer.
