  • 3 eggs
  • 3/4 teaspoon vanilla extract
  • 3/4 teaspoon light Karo syrup
  • 1 1/4 cups chunky peanut butter 320 grams

Instructions

  • Preheat oven to 350 degrees F. Have one or two large rimmed baking sheets lined with parchment paper.

  • Beat in the baking soda, then beat in the salt ONLY if you used unsalted butter.
