Best Recipe For Millionaires Shortbread Caramel

This delicious treat is made up of a shortbread base with caramel and milk chocolate. You can find multiple variations that substitute or add ingredients to cater for different tastes, dietary requirements or ingredient availability!

Caramel shortbread, also known as caramel squares, caramel slice, millionaire’s shortbread, millionaire’s slice, chocolate caramel shortbread, and Wellington squares is a biscuit confectionery item composed of a rectangular, triangular or circular shortbread biscuit base topped with caramel and milk chocolate. Sometimes I use dark chocolate but you can change this depending on taste.

How To Make The Shortbread For Your Caramel Squares

Start with making the shortbread. This doesn’t take long to do. I put on my ingredients in my kitchen aid and use the paddle accessory and mix until partially combined. Place the mixture evenly in your brownie tins and press down until the base is covered and even. Prick all over with a fork but not right through. Bake in the oven for about 26 minutes until golden brown. Leave in the tin to cool.

How To Make The Caramel For Caramel Slice

Melt the butter and sugar in a medium-hot pan then add the caramel. With a metal whisk mix constantly then when it starts to boil keep mixing for about 5 minutes until it thickens. Take off the heat and pour equal amounts on top of your shortbread. Place in the fridge to set.

How To Cut Millionaire’s Shortbread

When the caramel is set, (it should be quite firm) melt the chocolate and pour it over your caramel. When the chocolate is about to set (but not quite), this is the time to cut your caramel shortbread into squares. If you wait for the chocolate to set and harden when you cut it will crack and you won’t have a clean-cut slice.

TIP: If the chocolate has set and hardened run your cutter under hot water from the kettle. Wipe with kitchen towel and cut. This will slightly melt the chocolate so you can cut without cracking the chocolate.
