What are Millionaire Bars
Why are these treats called Millionaire Bars? Presumable the treats are so decadent only the wealthy would consume something so rich!
Making Millionaire bars has a few more steps than most bars - but don't be dissuaded as each step is quite easy. Also, the bars may be made a few days in advance and stored in the fridge or freezer.
Ingredients
You don't need any fancy ingredients to whip up these treats:
- All-purpose flour (you may use gluten-free flour), light or dark brown sugar, cornstarch
- Unsalted butter: use cold butter when making the shortbread base
- Vanilla extract
- An egg yolk
- Sweetened condensed milk: this recipe uses one 14-ounce can which is the size sold in most grocery stores
- Light or dark corn syrup
- Sea salt
- Chocolate: preferably a bittersweet chocolate as this will offset the sweetness of the caramel
- Heavy Cream
Step-by-Step Instructions for the Millionaire Bars
- Preheat oven to 350° and prepare pan.
Prepare a 9" cake pan or tart pan by spraying generously with non-stick spray. Cut a 9" circle of parchment paper and place in the pan.
- Make shortbread dough.
Combine flour, cornstarch, brown sugar and salt in a large bowl. Add the cold butter cubes. Work the butter into the flour by squeezing between your fingers. Continue to work the butter and flour until no large chunks remain and the mixture looks mealy.
- Add wet ingredients.
Add the egg yolk and vanilla extract. Stir until the mixture is moistened and holds together when squeezed.
- Fill pan and bake.
Pour the dough into the prepared pan. Press evenly into the bottom of the pan. Using a fork, poke 10 - 15 holes in the dough.
- Bake and Cool
Bake for 18 - 20 minutes. The top will be a light golden color. Allow to cool before proceeding with the caramel layer.
- Make the Caramel Layer
Place brown sugar, corn syrup, salt, butter and sweetened condensed milk in a medium saucepan. Whisk until well combined. Place the pan over medium heat and continue to whisk until the mixture begins boiling.
Insert a candy thermometer and heat until the mixture reaches 225° (approximately 5 minutes), whisking constantly to ensure the bottom does not burn. Remove the pan from the heat once the mixture reaches 225°. Immediately pour the caramel over the shortbread base. Allow to cool for 30 minutes.
- Chocolate Layer
Place chocolate in a bowl and heat on 50% microwave power in 30 second bursts. Stir the chocolate. Repeat the heating process until the chocolate is partially melted.
Heat the heavy cream until it just starts to boil. Pour over the softened chocolate. Allow to rest for 3 - 4 minutes then stir until smooth. If all the chocolate does not melt, place back in the microwave for another 30 seconds on 50% power.
Once the chocolate/cream mixture is smooth, pour over the caramel layer and spread evenly. Sprinkle coarsely ground sea salt over the chocolate. Place the pan in the refrigerator until set (approximately 1 hour).
Cut into wedges using a knife run under hot water (this will create a smoother cut through the chocolate and caramel).
