How to make peanut butter cookies with cake mix
Step 1: In a mixing bowl, beat the creamy peanut butter, oil, and eggs together until combined and smooth.
Step 2: Gradually add the yellow cake mix and mix until a uniform dough forms. The batter will be thicker than cake batter and hold its shape for scooping.
Step 3: Use a mini cookie scoop or tablespoon to portion dough onto a nonstick or lined baking sheet, leaving space between cookies.
Step 4: Roll each portion into a ball. Step 5: Press down with a fork in a crisscross pattern to flatten slightly.
Step 6: Bake at 350°F (175°C) for 12–15 minutes, until the edges are lightly browned and the centers are set. Allow cookies to cool on the pan for 2–3 minutes, then transfer to a wire rack to cool completely.
