  • 1 cup peanut butter at room temperature, chunky or creamy 235g
  • 1/2 cup light brown sugar 100g
  • 2 tablespoon coconut oil or butter, melted 17g
  • 2 eggs
  • 1 teaspoon vanilla
  • 1 cup rolled or old fashioned oats, GF certified if necessary 100g
  • 1 teaspoon baking soda
  • 1/4 cup M&Ms 50g
  • 1/4 cup semisweet chocolate chips 42g


  • Preheat oven to 350 F (180C) and line a baking sheet with parchment paper.
  • In a large bowl, mix together the peanut butter, coconut oil, brown sugar, eggs and vanilla with a wooden spoon or a spatula until smooth and combined.
  • Add the oats, and baking soda and stir until combined, then add the m&ms and chocolate chips and stir until mixed. The batter will be wet, that's fine!
  • Scoop dough onto prepared baking sheets using cookie scoop or rounded tbsp, leaving 2 inches of space between each dough ball.
  • Bake for 10-12 minutes until cookies are golden brown on the edges and completely set. Cool completely before enjoying (or enjoy warm, no judgement here!).
