The beauty of Homemade Millionaire Bars with Shortbread lies in their simple, quality ingredients. Each component plays a vital role: the shortbread crust offers a buttery crunch, the caramel imparts smooth, melt-in-your-mouth sweetness, and the chocolate adds a glossy, rich finish. Here’s everything you’ll need to create these gorgeous bars from scratch.

All-purpose flour: Provides structure to the shortbread crust, ensuring it crisps perfectly without crumbling apart.
Unsalted butter: Used in every layer for that essential creamy richness, from the shortbread to caramel to chocolate topping.
Granulated sugar: Sweetens and adds a slight crunch to the shortbread base.
Light brown sugar: Gives the caramel a deeper, molasses-like flavor and soft chewiness.
Sweetened condensed milk: The secret to that ultra-smooth, velvety caramel layer.
Light corn syrup: Helps prevent the caramel from crystallizing, keeping it silky and perfect.
Semi-sweet chocolate chips: Melt down to create a luscious chocolate topping that balances the caramel’s sweetness.

How to Make Homemade Millionaire Bars with Shortbread

Step 1: Prepare the Shortbread Crust

Start by mixing the flour, room temperature unsalted butter, and granulated sugar until you achieve a coarse, crumbly texture that will transform into a perfect shortbread crust. Press this mixture evenly into a 9-inch square pan, making sure it’s compact to hold the layers that come next. Bake the crust at 350°F for around 20 minutes until it’s lightly golden—this sets a sturdy yet tender base that will hold all those luscious layers perfectly.

Step 2: Cook the Caramel

As soon as you pull the shortbread out of the oven, it’s time for the caramel magic. Combine butter, light brown sugar, sweetened condensed milk, and corn syrup in a saucepan and bring to a boil over medium heat. Let it bubble vigorously for about five minutes—this step is crucial to develop that rich, chewy caramel texture. After removing from heat, stir vigorously for three minutes to thicken it further. Pour this warm caramel evenly over your shortbread crust while it’s still slightly warm, then let it sit at room temperature for 2-3 hours until fully set. This wait is tough, but patience ensures every bite melts in your mouth gloriously.

Step 3: Melt and Spread the Chocolate Topping

Next, melt your semi-sweet chocolate chips with a tablespoon of butter in the microwave, heating in one-minute bursts and stirring frequently to avoid overheating. Once glossy and smooth, pour the chocolate over the firm caramel layer and spread it evenly using a spatula. Pop the entire pan into the refrigerator for at least 30 minutes to let the chocolate completely harden. This final layer seals in the caramel and crust, giving you that classic millionaire bars finish with a beautiful shine and snap.

Step 4: Slice and Serve

When you’re ready to indulge, run a knife under hot water and dry it—this tip helps you cut through the layers cleanly without cracking the chocolate. Slice the bars into 20 half-inch thick pieces for perfect portions. These bars are best enjoyed fresh but also keep well for sharing or gifting!

Garnishes

While these bars are stunning on their own, adding a sprinkle of flaky sea salt on top of the warm chocolate before it sets can elevate the flavors beautifully, balancing the sweetness with a hint of savory magic. For a festive touch, you might sprinkle crushed toasted nuts like pecans or almonds to add extra crunch and a nutty aroma that pairs wonderfully.

Side Dishes

Serve these bars alongside a scoop of vanilla bean ice cream or a dollop of freshly whipped cream to bring out their decadent layers even more. A hot cup of coffee or rich espresso also pairs incredibly well, cutting through the sweetness with a warm, bitter edge that keeps your palate refreshed.

Creative Ways to Present

For parties or gifting, stack the Homemade Millionaire Bars with Shortbread on a decorative platter and drizzle a little extra melted chocolate or caramel sauce over the edges for a gorgeous presentation. Wrapping individual bars in parchment paper and tying with kitchen twine turns each piece into a charming edible gift that friends and family will adore.

Make Ahead and Storage

Storing Leftovers

These bars store wonderfully in an airtight container at room temperature for up to four days. Keep them away from heat or direct sunlight to maintain the chocolate’s glossy finish and caramel’s soft texture. If your kitchen is warm, refrigeration is a good option but bring them back to room temperature before serving for the best melt-in-your-mouth experience.

Freezing

Homemade Millionaire Bars with Shortbread freeze beautifully. Wrap individual bars tightly in plastic wrap and place them in a freezer-safe container or bag. They will keep for up to three months. When ready to enjoy, thaw them in the refrigerator overnight and then bring to room temperature to restore the perfect texture.

Reheating

Reheating isn’t usually necessary, but if you want to soften the bars slightly, a few seconds in the microwave (around 10-15 seconds) will do the trick. Be careful not to overheat, as this can cause the layers to separate or the chocolate to seize.

FAQs

Can I use milk chocolate instead of semi-sweet?

Absolutely! Milk chocolate will give the bars a sweeter, creamier top layer. Just be mindful that it melts faster and can be a bit softer, but it’s a delicious variation.

Is it possible to make the caramel without corn syrup?

Yes, but corn syrup helps keep the caramel smooth and prevents crystallization. If you don’t have it, maple syrup or honey can be used as alternatives, though the texture and flavor may vary slightly.

Can these bars be made gluten-free?

To make Gluten-Free Homemade Millionaire Bars with Shortbread, substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup. This will keep the crust’s texture tender and crumbly.

How can I make these bars more chewy?

If you prefer a chewier caramel, cook it for slightly less time and skip some of the vigorous stirring step. It will be a bit softer and delightfully gooey when sliced.

What is the best pan size for this recipe?

A 9-inch square baking pan is ideal. It helps the layers hold up well and produces bars the perfect size to serve and enjoy without being too thick or thin.
