Why We Love This Recipe
This recipe uses only five ingredients, including a boxed yellow cake mix, so it’s fast and convenient. The dough comes together quickly and bakes into cookies that are soft in the center with a slightly crisp edge—perfect for school snacks, bake sales, or last-minute treats.
Ingredients

- Peanut butter. Creamy peanut butter is recommended for the best texture, but use your favorite brand.
Complete ingredient list:
- 1 box yellow cake mix
- 2 eggs
- 1/3 cup oil (vegetable or canola)
- 1 cup creamy peanut butter
- 1/3 cup granulated sugar (for rolling)
Variation Ideas
- Chocolate chips: Fold in or press chocolate chips on top for a peanut butter–chocolate combo.
- White chocolate chips: Swap in white chips for a sweeter contrast.
- Reese’s cup or Hershey’s Kiss on top: Unwrap and press a candy into each cookie right after baking for a gooey, chocolate-peanut butter finish.
How to make cake mix peanut butter cookies
- Step 1. Preheat the oven to 350°F (175°C).

Step 2. In a large bowl, combine the cake mix, eggs, oil, and peanut butter. The batter will be thick—that’s normal.

Step 3. Use a cookie scoop or spoon to form 1-inch dough balls. Roll each ball in granulated sugar until coated, then place on a baking sheet. Press a fork into each ball to make a crisscross pattern.

Step 4. Bake for 9–11 minutes, until the cookies are lightly golden around the edges.

Step 5. Let the cookies cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.
Storage
Store completely cooled cookies in an airtight container at room temperature for up to 4 days. Layer with wax paper to prevent sticking.
Can you freeze peanut butter cookies?
Yes. Baked cookies freeze well for up to 3 months when stored in an airtight container or freezer bag. Separate layers with wax paper.
You can also freeze unbaked dough balls: place scooped dough on a baking sheet and flash-freeze until solid, then transfer to a freezer bag. When ready to bake, arrange frozen dough on a baking sheet and bake as directed, adding a few minutes to the bake time. Halfway through baking, press the fork pattern into the tops if desired.

Pro Tips
- Use a cookie scoop: Scoops create uniform cookies for even baking.
- Cool completely: Allow cookies to cool fully before storing to keep them from becoming soggy.
- Line your baking sheet: Use parchment paper or a silicone baking mat for easier cleanup.
- Chill sticky dough: If the dough is too sticky to shape, chill it briefly in the refrigerator.
