Step-by-Step Instructions

  2. Gradually beat in peanut butter, egg, and vanilla extract until smooth and well-combined.
  3. In a separate bowl, whisk together flour, rolled oats, salt, baking powder, and baking soda.
  4. Gradually add the dry mixture into the wet mixture, stirring gently until just combined.
  5. Fold in M&Ms and chocolate chips until evenly distributed.
  6. For thicker cookies, chill the dough in the refrigerator for about 30 minutes.
  7. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
  8. Drop rounded tablespoons of dough onto the prepared sheets, spacing them about 2 inches apart.
  9. Bake for 10–12 minutes until the edges are golden brown.
  10. Let cookies cool on baking sheets for 5 minutes, then transfer to a wire rack.
