Millionaire’s Shortbread
Rich layers of buttery shortbread, chewy caramel and chocolate ganache makes Millionaire’s Shortbread the ultimate, indulgent treat.
Ingredients and Substitutions
- Butter. I used salted butter but unsalted butter can be substituted.
- Caster sugar. I prefer using caster sugar for shortbread but granulated sugar can be used instead.
- Flour.
- Cornstarch.
- Sweetened Condensed milk.
- Golden syrup. Light corn syrup can be substituted.
- Dark chocolate. I prefer using dark chocolate to balance the sweetness of these cookie bars but you can use a mixture of dark/semi-sweet chocolate and milk chocolate if you prefer.
- Heavy cream.
- Sea salt flakes.
How to make Millionaire’s Shortbread
- Make the shortbread by combining room temperature butter, sugar, flour and cornstarch in a large bowl then mix together. I usually use my stand mixer fitted with the paddle attachment. Press into a 8x8in/20x20cm baking pan lined with parchment paper (I like to leave a little overhang on each side to make removing the cookie bars from the pan as easy as possible). Make sure the shortbread dough is an even layer then place in a preheated oven and allow to bake for 20 minutes or until golden brown on top. Remove from the oven and allow to cool.
- To make the caramel combine the condensed milk, butter, syrup and a pinch of salt together in a small saucepan set over medium heat and bring to a boil. Simmer, stirring continuously, until the caramel is thick and golden brown in color. Pour the caramel over the shortbread crust and spread into an even layer. Place in the fridge and allow to set.
- For the chocolate ganache, melt together the chocolate and cream then pour over the caramel. I added an extra layer of melted chocolate but this is optional and not necessary. Sprinkle with sea salt flakes then refrigerate until completely set. Remove from the baking pan and set on a cutting board.
- Slice the millionaire’s shortbread into bars with a very sharp knife then serve.
Can I make this ahead?
The Millionaire’s shortbread can be kept in an airtight container in the fridge for up to 7 days or at room temperature for up to 3 days.
