  • 1 cup sugar
  • 1 cup light brown sugar (packed)
  • 1 stick unsalted butter (room temp! not melted and not warmed up in the microwave)
  • 3 large eggs
  • cups peanut butter (chunky or smooth - do not use all natural)
  • 1 tbsp vanilla
  • 2 tsp baking soda
  • 1/2 tsp salt
  • tsp cinnamon
  • cups old fashioned oats
  • 1 cup (total) mixture of mini green and red m&ms and peanut butter green and red m&m's. *You can have all of one or the other. It's up to you. The mixture makes them extra yummy.*
  • 1 cup (total) semi sweet mini chocolate chips and white chocolate chips *You can have all of one or the other. It's up to you. The mixture makes them extra yummy.*
  • extra m&m's and chocolate chips to stick into the cookie for it to "look prettier" after they are done baking. *optional


  1. Preheat oven to 350°F. Line baking sheet with parchment paper.

  2. In a bowl cream together white and brown sugar with the butter until combined well and light and fluffy.

  3. Beat eggs in one at a time and then beat in peanut butter, vanilla, cinnamon, baking soda, and salt until combined.

  4. Add in the oats and mix together until combined well.

  5. Stir in m&m's and chocolate chips.

  6. Scoop 3 tablespoon sized cookie mounds onto cookie sheet and space them about two inches apart otherwise they will run into each other.

  7. Bake the cookies for 12 minutes then remove them from the oven and allow them to cool for at least 10 minutes on the cookie sheet before moving them to a cooling rack to finish cooling.

    *The key to most cookie baking is having them almost under baked a bit when removing from the oven and slowly finish "baking" just enough while on the cookie sheet. The perfect texture!!
