How to Make Caramel Slice
Preheat oven to 350°F.
Add in 1 cup of butter, egg and vanilla extract and mix until everything is well combined.
Bake for 20 minutes or until slightly golden and cooked through.
I made the caramel sauce as the crust was cooking, and it was ready just a few minutes after I pulled the crust out of the oven.
Allow the crust to cool slightly, then pour the caramel sauce over and spread it out evenly.
Let it sit at room temperature for 10 minutes, then chill in the fridge for at least 30 minutes and allow it to set before moving onto the chocolate layer.
Pour the chocolate chips and 2 tablespoons of butter into a heat proof mixing bowl set over a double boiler and stir just until the chocolate has melted.
Pour the chocolate over the caramel sauce and smooth using an offset spatula to get an even layer. Sprinkle some flaked sea salt over the top and chill in the fridge for several hours or overnight before cutting into small squares.
This is where you have to be patient, because if you cut into it too soon, the caramel will ooze out and make a mess.
To keep these bars fresh, you should store leftovers in an airtight container in the fridge for up to 5 days.
Caramel slice is a dessert that originated in Australia. You may hear it referred to by several different names, caramel squares, caramel slice, millionaire's shortbread, millionaire's slice, or chocolate caramel shortbread.
Even though the origin of Caramel Slice Bars is traced back to Australia, they are said to be adapted from a Scottish short bread all the way back to the 12th century, where they were topped with different kinds of fresh and dried fruits.
Variations of the Millionaires Shortbread
- Chocolate topping: This recipe uses sugar-free, semi-sweet chocolate chips. But you can use dark chocolate, milk chocolate or white chocolate. You can also use a combination of and make a chocolate swirl pattern.
- Additional toppings: Some versions of Scottish caramel slice added fresh fruits before serving. You can also sprinkle chopped nuts to the top of the chocolate before it sets up.
- Extracts: The shortbread crust uses vanilla extract, but if you want to add a slightly different flavor you could use almond extract instead. And for a more intense chocolate flavor, add a drop or two of coffee extract to the chocolate layer right before you pour it.
The number one reason caramel slice doesn't set is because the caramel sauce did not cook long enough. Don't rush cooking it. If it's not cooked long enough, your caramel slice will end up in a runny mess!
Another main cause the bars may be loose is because you didn't allow them to chill long enough in the fridge.
You sure can. Take the chilled bars and double wrap them in plastic wrap. Slip them into a freezer-safe, air-tight container. They should freezer well for up to three months.
Funny enough, the title comes from a play on words. Millionaire's Shortbread get their name because they are "insanely rich!"
First, make sure you allow at least a few hours for the caramel to firm up. Then, using a sharp knife, cut them into small squares (they are rich) and wipe the knife clean between each cut.
