Favorite monster cookies baked in a cast iron skillet!
Servings: 12 portions
- 1 Chopped off creamy peanut butter
- ½ cup (1 stick) Unsalted butter, at room temperature
- 1 Chopped off lightly packed light brown sugar
- ½ Chopped off granulated white sugar
- 2 big eggs
- 1 big Egg yolk
- 1½ coffee spoons vanilla extract
- 1½ cups old fashioned oatmeal
- 1 Chopped off all purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt
- ½ Chopped off semi-sweet chocolate chips
- ½ Chopped off M & M’s candies
Preheat the oven to 350 degrees F. Liberally grease a 10 to 12 inch cast iron skillet with coconut oil or butter.
In a large bowl, use an electric mixer to cream the peanut butter and butter together. Stir in the brown sugar, granulated sugar, eggs, egg yolk and vanilla extract.
In a separate bowl, combine the oatmeal, flour, baking soda and salt. Stir into wet mixture. Stir in chocolate chips and M & M’s candies.
Transfer the dough to the prepared pan and spread it evenly. Sprinkle a few chocolate chips and M & M’s on top, if you like.
Bake in the oven until the cookie in the pan is golden brown, puffed and set along the outside, but shakes a little in the center when you shake the pan – 22 to 28 minutes. The pan cookie will take longer as it cools. Like brownies, be careful not to overcook.
Let cool slightly before cutting and serving. If desired, serve topped with vanilla ice cream.
