Peanut Butter Cake Mix Cookies

Introduction

You’ll be amazed at how just four simple ingredients can create such wonderfully soft and chewy cookies with an intense peanut butter flavor. These cookies are the perfect solution for when you need a guaranteed crowd-pleaser with minimal effort. The cake mix creates a perfectly consistent texture that’s easy to master.

Prep & Cook Time

Prep Time: 15 minutes

Cook Time: 15 minutes

Total Time: 30 minutes

Servings: 20 cookies

Ingredients

• 1 cup creamy peanut butter
• 2 large eggs
• 1/2 cup vegetable oil
• 15.25 ounce yellow cake mix

Instructions

1. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone mats.
2. In a large mixing bowl, combine the creamy peanut butter, eggs, and vegetable oil. Stir until smooth and fully incorporated.
3. Add the entire box of yellow cake mix to the peanut butter mixture. Stir with a spatula or wooden spoon until a thick, uniform dough forms and no dry cake mix streaks remain.
4. Bake for 12-15 minutes, or until the edges are just set and the tops appear slightly cracked. The centers may look slightly soft.
5. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Variations

1. Stuffed Cookie: Flatten a dough ball, place a small piece of chocolate or a dollop of jam in the center, then seal with another piece of dough on top before baking.
2. Fork Crosshatch: Before baking, gently press down on each dough ball with a fork, then press again at a 90-degree angle to create the classic peanut butter cookie crosshatch pattern.
3. Thumbprint: Make an indentation in the center of each dough ball with your thumb before baking. After cooling, fill the well with a drizzle of melted chocolate or a small spoonful of fruit preserves.
4. Cookie Sandwiches: Once completely cooled, spread a layer of frosting or a dollop of additional peanut butter between two cookies to make a sandwich.

Tips for Success

1. For a slightly denser, fudgier cookie, chill the dough for 30 minutes before scooping and baking.
2. Use a standard 15.25 oz box of yellow cake mix. Using a “pudding in the mix” variety will yield a cakier texture.
3. Let the cookies rest on the hot baking sheet after removing them from the oven—this helps them set without becoming overbaked.

Storage & Reheating

Store completely cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the baked cookies for up to 3 months. To reheat, place a cookie in the microwave for 10-15 seconds to restore a warm, soft texture.

FAQ

Can I use chunky peanut butter?

Yes, chunky peanut butter will work and add small bits of peanut texture throughout the cookies.

Why are my cookies flat?

This is likely due to an overly warm dough. Chilling the dough for 30 minutes before baking will help prevent excessive spreading.

Can I use a different flavor of cake mix?

Absolutely! While yellow cake mix is classic, chocolate cake mix or even spice cake mix can create delicious flavor variations.

My dough seems too oily. What happened?

Ensure you measured the oil correctly. The dough will be quite soft and oily before baking, but this is normal for this recipe and results in a moist cookie.

Can I make the dough ahead of time?

Yes, you can cover the bowl of dough tightly and refrigerate it for up to 2 days before scooping and baking. Let it sit at room temperature for 15 minutes to soften slightly for easier scooping.

How do I know when the cookies are done?

The cookies are done when the edges look set and lightly golden. The centers will still appear soft but will firm up as they cool on the baking sheet.
