Ingredients
Scale
Shortbread Crust
- 1/2 cup unsalted butter, room temperature
- 1/2 cup white sugar
- 1 egg
- 1 tsp vanilla
- 1 cup flour
- 1/4 tsp salt
Peanut Butter Caramel
- 1/2 cup peanut butter
- 2 tbsp unsalted butter
- 1/4 cup heavy cream
- 1/2 cup light brown sugar
- pinch of salt
Chocolate Layer
- 10 oz semi sweet chocolate chips
- 1/4 cup heavy cream
Instructions
- Set the oven to 350 degrees.
- Next in a large mixing bowl add the butter and sugar. Beat with an electric mixer until light and fluffy. Then add in the egg and vanilla extract and beat until just combined.
- In a separate bowl combine the flour and salt. Add to the butter & sugar mixture and beat until thoroughly combined and a dough forms.
- Next line an 8×8 baking dish with parchment paper and add the shortbread dough to the pan. Spread and flatten evenly. I recommend using slightly wet fingers to avoid the dough sticking!
- Bake for 20 minutes or until the edges are browned.
- Once the shortbread crust is removed from the oven, let cool completely. Then make the peanut butter caramel. Add the peanut butter, butter, heavy cream, and light brown sugar to a small saucepan on the stove. Melt the ingredients together and bring to a boil. Reduce the heat and let simmer for a few minutes to thicken. Remove from the heat to thicken further and add a pinch of salt.
- Pour the peanut butter caramel over the completely cooled shortbread crust. Spread evenly and then place in the refrigerator for about 1 hour or until the caramel has hardened to the touch.
- Next begin the chocolate top layer. Simply melt the chocolate chips and heavy cream together. Melt in the microwave in 15 second intervals, stirring in between each one, or in a double boiler. The result may be a little thick, but do not worry that is how it’s supposed to be.
- Add the chocolate layer on top of the caramel and spread evenly. I again recommend using slightly wet fingers to do this. Then place in the fridge for another 1-2 hours to completely set.
- Add a generous sprinkle of salt, cut into squares, and enjoy!
