Millionaire’s shortbread pretty much rules. I mean, it’s shortbread, already buttery bliss all by itself, rendered awesomer by topping it with caramel and chocolate for what amounts to a triple-threat of delicious. It makes for a treat so rich you can kind of see where it gets its name.

But of course, with inflation being what it is, why stop at a million when you can have a billion? And so I present Peanut Butter Billionaire’s Shortbread, wherein two types of peanut butter is added to it and its awesome quotient is upped exponentially.

Prep time: 30 minutes
Cook Time: 30-40 minutes
Total time: 2 hours
Yield: 36 bite-sized portions

Peanut Butter Billionaire’s Shortbread


Peanut Butter Billionaire’s Shortbread Ingredients - Peanut Butter & Co. Smooth Operator peanut butter

For the shortbread layer
1 1/2 cups cups all-purpose flour
1/4 cup sugar
1 1/2 sticks butter, softened
3 tablespoons Smooth Operator peanut butter

For the middle layer
1/2 cup Smooth Operator peanut butter
10 ounces thick caramel sauce or Cajeta (Mexican Milk Caramel)

For the top layer
1 big bar (4 ounces) dark chocolate (I used Ghirardelli 60% dark)
1/4 cup Dark Chocolate Dreams peanut butter


1. Preheat the oven to 300°F

2. In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar until light and fluffy, about 2-3 minutes. Add the 3 tablespoons of peanut butter and mix only until incorporated. Add the flour last, mixing only until you can clump the dough together to form a ball.

3. Press this sandy shortbread mixture into a 9-inch square pan that has been greased and the bottom lined with parchment paper; smooth it with either your hands or a spatula. Pierce it with a fork.

4. Bake for 30-40 minutes until it is pale golden and has a dull finish on top.

5. Melt 1/2 cup of Smooth Operator peanut butter so that it is pourable. Pour on top of the shortbread layer, and gently spread over the peanut butter layer.

6. In a deep microwave safe bowl, or over the stovetop, gently heat your caramel or cajeta until it is pourable but still thick. Pour evenly over the shortbread in a zigzag pattern, so that you can easily spread it to cover the peanut butter without disturbing the even coverage over the shortbread. If these two caramel and peanut butter layers mingle a bit, don’t worry; it still tastes great. Just take care not to bring up pieces of the shortbread, because it will make your final product look messy.

7. Prepare the top layer. Break the chocolate into pieces and melt it along with the Dark Chocolate Dreams peanut butter in a saucepan over low heat. Pour and spread it over the caramel mixture. Once set, cut the caramel shortbread into pieces. These pieces can be stored in the refrigerator for 3-4 days.
