Ingredients

Scale

Main Ingredients

  • 4 Tbsp. butter
  • ¾ cup granulated sugar
  • ½ cup brown sugar (light, packed)
  • ½ cup milk (regular, oat, or cashew)
  • ¼ cup cocoa powder (regular or dark)
  • ⅔ cup peanut butter (creamy)
  • 2 tsp. vanilla extract
  • 3 cups old-fashioned oats
  • ¼ tsp. salt

Instructions

  1. Make the Base. Add butter to a medium-sized saucepan over medium heat. Once the butter has melted, add the granulated sugar, brown sugar, milk, and cocoa powder. Bring the mixture to a boil and allow it to boil for 1 minute, stirring occasionally to ensure everything is well combined and smooth. Remove from heat and stir in the peanut butter, vanilla extract, and salt until fully incorporated.
  2. Add Oats and Scoop. Pour the warm chocolate mixture over the oats in a large mixing bowl. Stir well to coat all the oats evenly with the chocolate sauce. Let the mixture sit for 5 minutes to slightly thicken, which helps the cookies hold together when scooped. Using a spoon or cookie scoop, form the mixture into 1 ½ tablespoon-sized balls.
  3. Chill and Enjoy. Arrange the cookie balls evenly spaced on a baking sheet lined with parchment paper. Press each ball down gently to slightly flatten. Refrigerate the cookies for at least 1 hour to set properly; they can be chilled overnight for the best texture. Serve chilled or at room temperature and enjoy a no-fuss chocolate oatmeal treat.

Notes

  • Use regular or plant-based milk according to preference or dietary restrictions.
  • Peanut butter can be substituted with almond or sunflower seed butter for a different flavor.
  • Make sure to use old-fashioned oats for the best texture; instant oats will result in a softer cookie.
  • Cookies must be refrigerated to set properly since they are no-bake.
  • For a nut-free version, replace peanut butter with sunflower seed butter and ensure all ingredients are processed in a nut-free facility.
