Ingredients

The following ingredients have 8 Servings
  • 3/4 cup butter
  • 1/2 cup white sugar
  • 1 cup brown sugar
  • 2 medium eggs
  • 1 teaspoon vanilla extract
  • 2 1/3 cups flour
  • 1/2 teaspoon salt
  • 3/4 teaspoon baking soda
  • 1 cup chocolate chips
  • 396-432 grams Mars bars (11-12 snack size bars cut in half lengthwise)

Instruction

  • Cream your butter and sugars together until they are light and fluffy. 
  • Add in the eggs, one at a time, beating in completely after each addition. 
  • Add the vanilla and mix in. 
  • Whisk together your dry ingredients and add to the butter/sugar mixture. Combine well then add the chocolate chips, mixing until they are spread through the dough evenly.
  • Take half of the cookie dough and press into the bottom of a pre-seasoned cast iron skillet. 
  • Take the cut up Mars bars and place into the skillet, making sure they are distributed evenly across the surface of the cookie dough.
  • Take the remaining cookie dough and cover the Mars bars, filling in the spaces all the way to the skillets edge, making a smooth top. If you are using a 10 inch skillet, using all the cookie dough will bring the cookie right up to the top of the skillet. If you are using a 12 inch, it will be just below the skillet's edge. Both are lovely, but choose your size depending on the look you wish to achieve.
  • Bake in a 350 degree oven for 30-35 minutes, until the cookie is baked through.
  • Serve warm, cutting into pie shaped wedges and top with vanilla ice cream if desired.
