Why This Recipe Works
This Millionaire Bars recipe is a winner because it balances simplicity with incredible flavor. Here’s why it works so well:
- The Shortbread Crust: Using a simple shortbread recipe creates a sturdy and buttery base that perfectly complements the sweet caramel and rich chocolate. The pre-baking of the crust ensures it’s firm enough to hold the other layers.
- The Gooey Caramel: The key to a perfect caramel layer is using a combination of sweetened condensed milk, butter, and brown sugar. This combination creates a thick, chewy, and deeply flavorful caramel that doesn’t crystallize easily. Slow cooking on the stovetop ensures the caramel reaches the ideal consistency.
- The Rich Chocolate Ganache: A simple ganache made with chocolate and heavy cream provides the perfect finishing touch. The ganache adds a smooth, luxurious texture and a bittersweet counterpoint to the sweetness of the caramel.
- Layered Perfection: The layering of the different textures and flavors is what makes these bars so special. Each bite is a delightful explosion of buttery, chewy, and chocolatey goodness.
Ingredients
- For the Shortbread Crust:
- 1 cup (2 sticks) unsalted butter, softened
- 1/2 cup granulated sugar
- 2 cups all-purpose flour
- 1/4 teaspoon salt
- For the Caramel Layer:
- 1 cup (2 sticks) unsalted butter
- 1 cup packed light brown sugar
- 1 (14 ounce) can sweetened condensed milk
- 1/4 teaspoon salt
- For the Chocolate Ganache:
- 12 ounces semi-sweet chocolate chips
- 1 cup heavy cream
- 1 tablespoon unsalted butter (optional, for extra shine)

Instructions
- Prepare the Shortbread Crust:
- Preheat oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
- In a large bowl, cream together the softened butter and sugar until light and fluffy.
- In a separate bowl, whisk together the flour and salt.
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
- Press the dough evenly into the prepared baking pan.
- Bake for 20-25 minutes, or until lightly golden brown.
- Let the crust cool completely before adding the caramel layer.
- Make the Caramel Layer:
- In a medium saucepan, melt the butter over medium heat.
- Stir in the brown sugar, sweetened condensed milk, and salt.
- Bring to a simmer, stirring constantly, and cook for 5-7 minutes, or until the caramel is thick and golden brown. Be careful not to burn the caramel.
- Pour the caramel evenly over the cooled shortbread crust.
- Let the caramel cool completely. This can take about an hour at room temperature or you can speed it up by placing it in the refrigerator for about 30 minutes.
- Prepare the Chocolate Ganache:
- Place the chocolate chips in a heatproof bowl.
- In a small saucepan, heat the heavy cream over medium heat until it just comes to a simmer. Do not boil.
- Pour the hot cream over the chocolate chips.
- Let the mixture sit for 1 minute to soften the chocolate.
- Gently whisk the mixture until smooth and glossy. Stir in the butter (if using) for extra shine.
- Pour the ganache evenly over the cooled caramel layer.
- Chill and Cut:
- Refrigerate the bars for at least 2 hours, or preferably overnight, to allow the ganache to set completely.
- Before cutting, let the bars sit at room temperature for about 15-20 minutes to soften slightly. This will make them easier to cut.
- Use a sharp knife to cut the bars into squares or rectangles. For clean cuts, run the knife under hot water and wipe it dry between each cut.
- Serve and Enjoy!
Tips for Success
- Don’t Overmix the Shortbread: Overmixing the shortbread dough will result in a tough crust. Mix just until the ingredients are combined.
- Watch the Caramel Carefully: The caramel can burn easily, so stir it constantly and keep a close eye on it. If it starts to look too dark, reduce the heat.
- Use Good Quality Chocolate: The quality of the chocolate will affect the flavor of the ganache. Use a good quality semi-sweet chocolate for the best results.
- Chill Thoroughly: Chilling the bars completely is essential for easy cutting and a firm texture.
- Warm Knife for Clean Cuts: As mentioned above, using a warm knife will help you achieve clean, professional-looking cuts.
- Variations: Feel free to experiment with different variations. Add nuts to the shortbread or caramel, use different types of chocolate for the ganache (milk, dark, or white), or sprinkle the top with sea salt for a salty-sweet twist.
Storage Instructions
Store Millionaire Bars in an airtight container in the refrigerator for up to 5 days. They can also be frozen for up to 2 months. Wrap the bars individually in plastic wrap before freezing to prevent freezer burn.

FAQ
- Can I use salted butter? While unsalted butter is preferred for better control over the salt level, you can use salted butter. Just reduce the amount of salt added in the shortbread and caramel layers.
- Can I make these bars gluten-free? Yes, you can substitute the all-purpose flour in the shortbread crust with a gluten-free all-purpose flour blend.
- My caramel is too hard. What did I do wrong? You likely overcooked the caramel. Next time, cook it for a shorter amount of time, and make sure to stir constantly.
- My chocolate ganache is grainy. How can I fix it? This can happen if the chocolate gets too hot. Try adding a tablespoon of softened butter and whisking vigorously. If that doesn’t work, you may need to start over.
- Can I make these bars ahead of time? Absolutely! In fact, they are even better the next day after the flavors have had a chance to meld together.
