- 1 tablespoon heavy cream – Helps to create a smooth caramel texture.
- 1 1/4 cups chocolate chips (milk or semi-sweet) – The perfect topping for our bars.
- 2 tablespoons peanut butter (for drizzling) – For an extra peanut buttery finish.
- 1/2 cup mini Reese’s Pieces (optional) – A fun and colorful addition, though not necessary.
Essential Tools for Success

Peanut Butter Caramel Shortbread Bars (millionaire bars): From Prep to Plate
Step 1: Prepare the Shortbread Layer
Start by preheating your oven to 350°F (175°C). In a mixing bowl, cream together 1 stick of softened butter and 1/2 cup of granulated sugar until light and fluffy. Add in 1 teaspoon of vanilla extract and mix well. Gradually add 1 cup of flour until combined. The mixture will be crumbly but should hold together when pressed.
Step 2: Bake the Shortbread
Press the shortbread mixture evenly into the bottom of your greased 9×9 inch baking pan. Bake for 15-20 minutes, or until the edges are lightly golden. Remove from the oven and let it cool slightly.
Step 3: Make the Caramel Layer
In a double boiler or microwave-safe bowl, combine 25 unwrapped caramels, 2 tablespoons of peanut butter, and 1 tablespoon of heavy cream. Heat gently until melted and smooth, stirring frequently. Once melted, pour the caramel over the baked shortbread layer, spreading it evenly.
Step 4: Prepare the Chocolate Topping
In the same double boiler or microwave, melt 1 1/4 cups of chocolate chips until smooth. Pour the melted chocolate over the caramel layer, spreading it evenly. If you’re using them, sprinkle 1/2 cup of mini Reese’s Pieces on top for a fun crunch and color.
Step 5: Drizzle with Peanut Butter
In a small bowl, melt 2 tablespoons of peanut butter and drizzle it over the chocolate layer for an extra touch of peanut buttery goodness.
Step 6: Chill and Slice
Refrigerate the bars for at least 2 hours to allow everything to set. Once set, lift the bars out of the pan using the edges of the parchment paper. Cut into squares and enjoy your homemade Peanut Butter Caramel Shortbread Bars!
Year-Round Variations
These bars are versatile and can be adapted for different occasions and seasons:
- For a festive touch, add crushed peppermint or sprinkles on top during the holidays.
- Swap out the chocolate chips for white chocolate for a sweeter twist.
- Incorporate nuts like chopped peanuts or walnuts for added crunch.
- For a tropical flair, substitute the peanut butter with almond butter and add shredded coconut.
Frequent Missteps to Avoid
To ensure your Peanut Butter Caramel Shortbread Bars turn out perfectly, keep these common mistakes in mind:
- Not allowing the shortbread to cool before adding the caramel can lead to a messy layer.
- Overheating the caramel can cause it to become too thick and unmanageable.
- Forgetting to line your baking pan can result in sticky bars that are challenging to remove.
- Cutting the bars too soon can cause them to crumble. Patience is key!
Keep-It-Fresh Plan
To keep your Peanut Butter Caramel Shortbread Bars fresh and delicious:
- Store in an airtight container at room temperature for up to one week.
- For longer storage, refrigerate the bars, where they can last for up to two weeks.
- These bars freeze well! Wrap them individually in plastic wrap and store in a freezer-safe container for up to three months.
Popular Questions
Can I use natural peanut butter instead of regular peanut butter?
Yes, you can use natural peanut butter, but be aware that it may change the texture slightly. Natural peanut butter is usually runnier and might require a bit more heavy cream to achieve the right consistency.
What can I substitute for the caramels?
If you can’t find caramels, you can make your own using sugar, butter, and cream. Alternatively, you can use store-bought caramel sauce, but make sure to reduce the amount of heavy cream in the recipe.
How do I know when the bars are set and ready to cut?
The bars are set when the chocolate topping has hardened and the caramel is no longer sticky to the touch. Chilling in the refrigerator helps speed up this process.
Can I add different toppings to these bars?
Absolutely! You can get creative with toppings. Consider adding crushed cookies, sprinkles, or even a drizzle of white chocolate for a unique twist.
