Peanut Butter Cake Mix Cookies Recipe

These peanut butter cake mix cookies are soft, chewy, and incredibly easy to make with just a few ingredients. I love how the cake mix gives them the perfect texture while the peanut butter adds rich, nutty flavor. They come together in minutes, making them ideal for busy days, last-minute desserts, or a quick sweet fix. Perfect with a glass of milk, packed in lunchboxes, or served at parties, these cookies are a foolproof treat everyone will enjoy.

Ingredients Equipment Method Notes

Ingredients
  

  • 1 box yellow cake mix 15.25 oz
  • 1 cup creamy peanut butter
  • 2 large eggs
  • ½ cup vegetable oil or melted butter for richer flavor
  • ½ cup granulated sugar optional for rolling
  • ½ teaspoon vanilla extract optional, for extra flavor

Equipment

  • Mixing bowl
  • Whisk or hand mixer
  • Measuring cups and spoons
  • Baking sheet
  • Parchment paper or silicone baking mat
  • Cooling rack

Method
 

Step 1: Preheat the Oven
  1. I preheat my oven to 350°F (175°C) and line a baking sheet with parchment paper.
Step 2: Mix the Ingredients
  1. In a large bowl, I combine the cake mix, peanut butter, eggs, oil, and vanilla. I stir until the dough looks smooth and thick.
Step 3: Shape the Cookies
  1. I scoop about a tablespoon of dough, roll it into a ball, and gently coat it in sugar for a slightly crisp texture. Then I place the dough balls on the prepared baking sheet, leaving space between them.
Step 4: Bake
  1. I bake the cookies for 10–12 minutes until the edges look set but the centers remain soft.
Step 5: Cool and Serve
  1. I let the cookies rest on the sheet for about 5 minutes, then transfer them to a cooling rack. They firm up as they cool, and that’s when they’re perfect.

Notes

These cookies stay fresh in an airtight container for about 4–5 days. If I want to save them for later, I freeze the baked cookies and warm them in the microwave for 15 seconds when I’m ready to enjoy them.
