Ingredients

The following ingredients have 4 Servings
  • 1 Cup Butter, Partially Melted ((220g))
  • 3/4 Cup Brown Sugar ((130g))
  • 1/2 Cup Sugar ((100g))
  • 2 Large Eggs
  • 1 Tbsp. Vanilla Extract
  • 2 and 3/4 Cups All Purpose Flour ((330g))
  • 1 tsp Baking Powder
  • 1 Cup Chocolate Chips ((180g))
  • 16 Oreo Cookies
  • 1 Cup Chocolate Buttons ((180g))
  • 12-14 Marshmallows, (OR 1 Cup Mini Marshmallows)

Instruction

  • Preheat the oven to 180°C (350°F) and line a 9"x9" baking pan with baking paper.
  • Beat the partially melted butter until creamy and add the brown sugar and sugar creaming them together.
  • Add the eggs one at a time beating well in between. Add the vanilla extract.
  • Add in the flour and baking powder and mix together.
  • Add the chocolate chips and crush 2 of the Oreo cookies and stir in to the batter.
  • Spread half of the cookie dough into the base of the baking pan.
  • Top with the remaining 14 Oreos, spread around the base.
  • Sprinkle over the chocolate buttons in an even layer.
  • Place the marshmallows around on top. Some can be halved, others whole, until they are spread around reasonably evenly. Remember they will spread when baking.
  • Dot over the remaining cookie dough so the marshmallows and Oreos are mostly covered.
  • Bake for around 25-35 minutes. The middle will wobble due to the marshmallows but the tops and sides will be lightly golden. I take mine out at 25 minutes for a more gooey, slightly under-baked cookie dough.
