Light Brown Sugar
To a large mixing bowl add the butter & sugar. Beat with an electric mixer until light & fluffy.
Add the remaining shortbread ingredients - vanilla extract, egg, flour, and salt. Combine until a dough forms. Add the dough to a pan and flatten evenly. Bake.
Add the peanut butter, butter, heavy cream, and light brown sugar to a small saucepan. Melt together and bring to a boil. Let simmer & thicken. Add salt.
Pour the peanut butter caramel over the cooled shortbread. Place in the refrigerator until the caramel has hardened to the touch. Then melt the chocolate and heavy cream together. Spread chocolate layer on top of the caramel. Cool again, then enjoy!
