Cuisine: American

Ingredients

  • 1/2 cup butter softened
  • 3/4 cup light brown sugar firmly packed (dark also works)
  • 1 tsp vanilla extract
  • 1 large egg
  • 3/4 cups creamy peanut butter
  • 1/2 cup all-purpose flour
  • 1/2 tsp baking soda
  • 1 tsp cornstarch
  • 1 cup rolled oats
  • 1/2 cup plain M&Ms
  • 1/2 cup semi-sweet chocolate chips

Instructions

    Cup of Yum
  1. In a large mixing bowl, cream the butter and sugar for about 4 minutes or until creamy and pale. Add the vanilla and beat again. Then add the egg and beat until smooth. Add the peanut butter and beat until combined.
  2. In a separate bowl, sift the flour, baking soda, cornstarch and gently whisk together. Then add the dry ingredients to the wet and gently fold together. Add the rolled oats, M&M's and chocolate chips and stir until combined. 
  3. Cover the bowl with plastic wrap and refrigerate for at least one hour.
  4. Line two oven trays with baking paper. Preheat the oven to 350 F.
  5. Grab cookie dough from the fridge. The dough will still be a bit sticky but it should be firm enough to roll balls using your hands.
  6. Line the balls (approximately 1 heaped tablespoon) of cookie dough onto the prepared trays and then flatten slightly using your hand or a spatula, as they wont spread out as much as a normal cookie would. Press a few extra M&M’s and chocolate chips on top if desired.
  7. Bake the cookies for approximately 12 minutes or until golden brown on the edges. Leave the cookies to cool slightly before gently moving to a wire rack to cool completely.

Notes

  • These cookies can be made small or large, whatever you prefer. 
  • Storage – Store these covered in an airtight container at room temperature for about 3 days, or in the freezer for 3 months.
