This section includes ingredient notes and substitution options. Get all measurements, ingredients, and instructions in the printable recipe card at the end of this post.
- Chocolate Cake Mix — Boxed cake mix is used as a shortcut to replace the dry ingredients in chocolate cookies such as all purple flour, sugar, unsweetened cocoa powder, baking powder, and salt. I like to use devil’s food cake mix for a deep chocolate flavor, but you can use milk chocolate, double fudge, or any other type.
- Eggs — Eggs bind all the ingredients together. Let them come to room temperature for easy mixing.
- Vegetable Oil — Canola oil works, too.
- Pure Vanilla Extract — A little vanilla extract gives the cookies a little extra depth of flavor and that classic bakery scent.
- Peanut Butter Chips — Reese’s peanut butter chips give the cookies that delicious nutty flavor. Remember to reserve some to place on top of the cookie dough balls so they’ll look picture perfect. You can replace them with semi-sweet chocolate chips or milk chocolate chips, if you prefer.

How to Make Chocolate Peanut Butter Chip Cookies with Cake Mix
This section shows you how to make the recipe with step-by-step photos and instructions. For the full printable recipe, see the recipe card below.
Prepare the dough: Add the chocolate cake mix, eggs, oil, and vanilla to a large mixing bowl. Mix well. Stir in about two-thirds of the chips. Cover the bowl with plastic wrap and chill for at least 20 minutes.
Get ready: Preheat the oven to 350°F while the dough is chilling. Line your baking sheets with parchment paper — do not spray with cooking oil because that will cause the dough to spread too much and flatten the cookies.
Bake the cookies: Use a cookie scoop (or Tablesoon) to portion the dough and roll it into balls. Place the balls of dough 2 inches apart on the cookie sheet. Press a few extra peanut butter chips on top of the cookies before putting them in the oven. Bake at 350°F for 8-10 minutes, until the tops of the cookies are set.
Cool the cookies: Allow the warm cookies to cool on the cookie sheet for 10-15 minutes before moving them to a cooling rack to completely cool.
These chewy chocolate cookies are best served with a tall glass of milk. If it’s fall or winter and you want to feel cozy, try them with a big mug of white hot chocolate.
Storage and Freezing
Store chocolate peanut butter chip cookies in an airtight container at room temperature for up to 5 days.
To freeze, wrap cookies individually in plastic wrap or foil and place in a heavy-duty freezer bag for up to 3 months. Thaw cookies at room temperature for at least 30 minutes before serving. Y
The dough also freezes well. Flash-freeze cookie dough balls on a cookie sheet then transfer to a freezer baggie or freezer-safe container.
Tips and Tricks for Chewy Chocolate Peanut Butter Cookies
- Do not overbake the cookies. They won’t look quite done when you take them out of the oven, but they’ll finish baking as they cool on the cookie sheet. This also gives them time to set up before moving them to the cooling rack, as they’re rather delicate when you first take them out of the oven.
- Chilling the dough may seem like a hassle, but it makes the dough much easier to scoop and keeps the cookies from spreading too much while baking.
- Use a cookie scoop for perfectly portioned cookies every time. A #60 cookie scoop holds a tablespoon of dough and is just right for making cake mix cookie recipes.
Additions and Variations
Use candy pieces: Instead of peanut butter chips, you can top your delicious chocolate cookies with Reese’s Pieces for a similar flavor or M&Ms if you want extra chocolate.
Switch up the cake flavor or baking chips. You can make so many different variations of cake mix cookies. Some favorites are:
- Red velvet cake mix cookies with white chocolate chips
- Cake mix chocolate chip cookies
- Spice cake cookies with butterscotch or cinnamon chips
- Chocolate cake mix cookies with peppermint chips (great for Christmas!)
Add different mix-ins and toppings. Feel free to add in some extras like chopped nuts, chocolate chunks, chopped candy, mini marshmallows, or a sprinkle of sea salt on top.
Make ’em bigger: As written, the recipe makes about 24 smaller cookies. If you want like large, bakery-style cookies, use 2 Tablespoons of dough per cookie. You will get about 12 large cookies this way.
