Millionaire Shortbread

Step 1

Preheat oven to 300°. Line a 13"-x-9" pan with parchment paper and spray with cooking spray. Make shortbread layer: Cream softened butter with sugar until light and fluffy. Add flour and vanilla and mix until a bread crumb texture forms.

Step 2

Press mixture into a prepared pan and prick all over with a fork.

Step 3

Bake until lightly golden, 30 minutes. Let cool completely.

Step 4

Make caramel layer: in a small saucepan over medium-low heat, stir caramels and cream together until melted, 10 minutes. Pour over cooled shortbread crust.

Step 5

Make chocolate layer: Melt chocolate in microwave in 30 second intervals and stir until smooth. Pour over caramel layer.

Step 6

Refrigerate 20 minutes until firm, then slice into bars. Top with flaky sea salt.
