Easy Cake Mix Peanut Butter Cookies – Just 4 Ingredients
Ingredients
1 cup creamy peanut butter
2 large eggs
½ cup vegetable oil (or melted butter for extra richness)
1 box yellow cake mix (15.25 oz)
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a large mixing bowl, combine peanut butter, eggs, and oil. Mix until smooth.
Slowly add in the dry cake mix, stirring until a thick dough forms.
Roll dough into 15 evenly sized balls and place on prepared baking sheet.
Using a fork, press down on each ball in a crisscross pattern to create the classic peanut butter cookie look.
Bake for 10–15 minutes, or until the edges are lightly golden. Let cool on the sheet for 5 minutes before transferring to a wire rack.
