Why Peanut Butter Chocolate Cake Mix Cookies Recipe Is Worth It
Peanut Butter Chocolate Cake Mix Cookies Recipe gives you bakery-level flavor with one bowl and a box of chocolate cake mix. You mix everything by hand, scoop, and bake, which keeps cleanup painless. The peanut butter adds moisture and richness, while the cake mix guarantees a soft crumb every time.
You still get room to play. Toss in chips, stuff with mini peanut butter cups, or finish with flaky salt for that sweet-salty hit.
Tastes like a peanut butter cup collided with a brownie in cookie form, and the batch disappears before the rack cools. ★★★★★
Ingredients You Need
- 1 box chocolate cake mix, 15.25 ounces (Betty Crocker or Duncan Hines; if your box weighs more, add 1 to 2 teaspoons milk as needed)
- 1 cup creamy peanut butter (Jif or Skippy work great; natural peanut butter works if fully stirred and you add a splash of milk if dry)
- 2 large eggs, room temperature
- 1/3 cup neutral oil or melted unsalted butter
- 2 teaspoons pure vanilla extract
- 1 cup chocolate chips or peanut butter chips
- 1 to 2 tablespoons milk only if the dough looks crumbly
- Flaky salt for topping, optional
- Optional mix-ins: 3/4 cup chopped mini peanut butter cups, 1/2 cup roasted peanuts
Equipment
- Large mixing bowl, whisk, and sturdy spatula
- Cookie scoop, about 1.5 tablespoons
- 2 rimmed baking sheets lined with parchment
- Wire rack for cooling
Quick Tips & substitutions
- Preheat the oven fully; hot sheets help set edges fast and keep centers soft.
- Use room temp eggs so the dough mixes smoothly.
- Natural peanut butter needs a good stir; add 1 tablespoon milk if the dough looks sandy.
- Aim for 1.5 tablespoon scoops; you should land around 22 to 24 cookies.
- Pull the cookies when edges set and tops look puffed; they keep cooking on the sheet.
- Chill sticky dough for 10 minutes if your kitchen runs warm.
- Bake a test cookie; adjust time by 1 minute to match your oven.
- Gluten-free chocolate cake mix works; use oil and dairy-free chips for a dairy-free batch.
- Want extra peanut punch? Swap half the chocolate chips for peanut butter chips.
How to Make Peanut Butter Chocolate Cake Mix Cookies Recipe
Step 1: Preheat and prep
- Heat the oven to 350 F. Line two baking sheets with parchment.

Step 2: Mix the wet ingredients
- In a large bowl, whisk eggs, oil or melted butter, peanut butter, and vanilla until smooth and glossy.
Step 3: Add the cake mix

- If the dough looks crumbly, add milk 1 teaspoon at a time until it holds together.
Step 4: Fold in goodies
- Stir in chocolate chips and any optional mix-ins.
- Let the dough sit 5 minutes so the cake mix hydrates and firms slightly.
Step 5: Scoop and shape
- Scoop 1.5 tablespoon mounds onto the sheets, spacing about 2 inches apart.
- Press each mound gently to a thick disc so they bake evenly.
Step 6: Bake
- Bake 8 to 10 minutes, until edges set and centers look soft and slightly underdone.

Step 7: Cool
- Let cookies rest on the sheet 2 minutes to set, then move them to a wire rack.

Storage
Store cooled cookies in an airtight container at room temperature for up to 4 days. Refrigerate for up to 1 week if you like a firmer, fudgier texture. Freeze baked cookies for up to 2 months; thaw at room temp or warm one cookie in the microwave for 7 to 10 seconds. Freeze unbaked dough balls for up to 2 months and bake them straight from frozen, adding 1 to 2 minutes to the time.
