Chocolate Caramel Shortbread Bars (Easy Millionaire Bars Recipe)
The Homemade Candy Bar That Disappears Faster Than Halloween Candy
I made these on a random Tuesday night because I couldn't stop thinking about those chocolate caramel candy bars I used to sneak from my dad's Halloween stash. You know that magical moment when you bite through a crisp chocolate shell and hit that long, gooey caramel stretch? That's exactly what inspired these bars.
My husband wandered into the kitchen while they were chilling in the refrigerator and just stood there staring at the pan. The next afternoon, I finally sliced them into neat little squares. Before dinner was even on the table, he'd already eaten three.
No excuses.
No regrets.
Just pure happiness.
These Chocolate Caramel Shortbread Bars have everything you love about your favorite candy bar—but somehow they're even better homemade. The buttery shortbread crust melts in your mouth, the caramel stays perfectly soft without running everywhere, and the rich chocolate topping sets with that satisfying snap before melting into silky peanut butter goodness.
They're elegant enough for holiday dessert tables, bake sales, birthdays, and family gatherings, but simple enough to make any weekend when you're craving something sweet.

Why This Recipe Works
Each layer has its own purpose.
The buttery shortbread base creates a sturdy yet tender foundation.
Adding heavy cream to the caramel keeps it silky and soft after chilling.
The combination of milk chocolate, semi-sweet chocolate, and creamy peanut butter creates a rich topping that's smooth, glossy, and slices beautifully.
After a few hours in the refrigerator, every layer sets perfectly while staying deliciously tender.

How to Make Chocolate Caramel Shortbread Bars
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C).
Line an 8x8-inch baking pan with parchment paper, leaving extra paper hanging over the sides for easy lifting later.
Step 2: Make the Shortbread Crust
Combine:
- Flour
- Softened butter
- Powdered sugar
- Salt
Mix until a soft crumbly dough forms.
Press firmly into the bottom of the prepared pan.
Bake for 15–18 minutes, until the edges are lightly golden.
Cool completely.
Step 3: Prepare the Caramel Layer
Warm the caramel sauce together with the heavy cream until smooth.
Spread evenly over the cooled crust.
Refrigerate for about 30 minutes until slightly firm but still soft.
Step 4: Make the Chocolate Layer
Place the milk chocolate chips, semi-sweet chocolate chips, and peanut butter into a microwave-safe bowl.
Microwave in 30-second intervals, stirring between each until completely smooth.
Spread evenly over the caramel layer.
Step 5: Chill
Refrigerate for at least 2 hours until completely firm.
Lift the bars from the pan using the parchment paper.
Slice into squares using a warm, sharp knife.
