Salted Caramel Oatmeal Cookie Pie is a soft and chewy, classic oatmeal cookie base with a homemade salted caramel filling, baked as a pie (or cake) and served in slices with an oozing salted caramel centre.
Place the butter and brown sugar in a saucepan over medium heat.
Allow the brown sugar to dissolve and add the milk or cream and bring to the boil for 2-3 minutes and then remove from heat.
Add the salt and set aside while you make the oatmeal cookie dough.
Preheat the oven to 180°C (350°F) and line a 20cm round pie dish or spring-form pan with baking paper and grease the sides.
Melt the butter and mix with the dark brown sugar, brown sugar and sugar together.
Mix in the vanilla extract and egg.
Add the flour, oats, baking soda, baking powder and chocolate chips and mix together.
Spread half of the dough into the base of the prepared pan and then pour over the salted caramel sauce.
Blob the remaining dough over the top in as even a layer as you can and place in the oven for 25-30 minutes. The top and sides will be lightly golden but the middle will wobble slightly due to the salted caramel filling.
Allow to come to room temperature before slicing as the salted caramel sauce will run.
