Prep & Cook Time
Prep Time: 5 minutes
Cook Time: 40 minutes
Total Time: 45 minutes
Servings: 20 cookies
Ingredients
- 1 box chocolate cake mix ({13.25 ounces})
- ⅔ cup all purpose flour
- ½ teaspoon espresso powder ({optional})
- 2 large eggs
- ⅓ cup vegetable oil
- 2 Tablespoons sour cream
- ½ cup mini chocolate chips
- ½ cup peanut butter chips
- ½ cup peanut butter
Instructions
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
- In a large bowl, whisk together the dry chocolate cake mix, all-purpose flour, and optional espresso powder until well combined.
- To the dry ingredients, add the eggs, vegetable oil, and sour cream. Use a wooden spoon or a hand mixer on low speed to mix until a thick dough forms. Avoid overmixing.
- Add the mini chocolate chips and peanut butter chips to the dough. Mix until they are evenly distributed.
- Scoop the dough into about 20 portions (approximately 1.5 tablespoons each) and roll into balls. Place the dough balls on the prepared baking sheets, spacing them about 2 inches apart.
- Slightly flatten each dough ball with your fingers. Using the back of a spoon or your thumb, make a small well in the center of each cookie.
- Spoon about ½ teaspoon of peanut butter into the well of each cookie.
- Bake for 9-11 minutes, or until the edges are set but the centers still look soft. The cookies will continue to firm up as they cool.
- Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Chocolate-Dipped: Once cooled, dip half of each cookie in melted chocolate and let it set.
- Stuffed Cookie Style: Instead of topping with peanut butter, wrap a scoop of dough around a small, frozen peanut butter cup.
- Larger Bakery-Style: Make 9-12 larger cookies and increase the baking time by 1-2 minutes.
- Swirl: Warm the ½ cup of peanut butter slightly and drizzle it over the cookies as soon as they come out of the oven, then use a toothpick to swirl.
Tips for Success
- Use a cookie scoop for uniformly sized cookies that bake evenly.
- If the dough is too sticky to handle, chill it for 15-20 minutes before scooping and rolling.
- For extra flavor, toast the peanut butter chips in a dry skillet for a minute before adding them to the dough.
Storage & Reheating
Store cooled cookies in an airtight container at room temperature for up to 5 days. For a warm, fresh-from-the-oven experience, reheat a cookie in the microwave for 10-15 seconds.
FAQ
Can I use a different cake mix flavor?
Yes, a devil’s food cake mix works perfectly. A standard chocolate fudge mix is the recommended type.
What can I substitute for the sour cream?
Plain, full-fat Greek yogurt is a perfect 1:1 substitute for the sour cream in this recipe.
My dough is very sticky. What should I do?
This is normal. Simply chill the dough for 15-20 minutes to make it easier to handle. You can also lightly flour your hands when rolling the balls.
Why is espresso powder optional?
It enhances the chocolate flavor without making the cookies taste like coffee. You can omit it entirely if you don’t have any.
Can I freeze the cookie dough?
Absolutely. Scoop the dough balls onto a tray, freeze solid, then transfer to a freezer bag. Bake from frozen, adding 1-2 minutes to the baking time.
Can I use regular-sized chocolate chips?
Yes, but mini chocolate chips distribute better in the dough. If using regular chips, they may sink a bit more.
