Instructions

Caramel Sauce;

Place the butter and brown sugar in a saucepan on a medium to high heat.
Once the butter has melted, add the milk and bring to the boil.
Boil for at least 2 minutes before removing from the heat.
Allow to cool while you make the peanut butter cookie dough.

Peanut Butter Cookie Dough;

Preheat the oven to 180°C (350°F) and line an 9"x9" baking pan with baking paper and set aside.
Melt the butter and peanut butter together.
In a large mixing bowl, place the brown sugar, sugar and melted butters into the bowl and mix together.
Beat in the eggs and vanilla extract.
Beat in the flour, baking soda, baking powder and chocolate chips and mix until all combined. The mixture should be wet but slightly crumbly.
Press half of the mixture into the prepared pan. Pour over the caramel sauce and then top with the marshmallows. Dollop the remaining dough over in an even layer.
Bake for around 25-30 minutes. The top and sides will be lightly golden and the middle will only have a slight wobble.
