Millionaire Shortbread

Crumbly Shortbread Base, Sweet and Delicious Caramel Finished with a Layer of Milk Chocolate.


So I absolutely LOVE Millionaire Shortbread whenever I’m in a cafe or bakery I always order a slice of it but until now I had never made it. I never really baked biscuits I only ever made cakes or cupcakes but I’m trying to widen my baking skills and so decided this had to be one of the first that I made. I did some baking research looking at different recipes and ways to make Millionaire Shortbread before I attempted to make my own.

I was surprised and just HOW EASY it is to make Millionaire Shortbread including the caramel. Making caramel is something that has always scared me. I attempted to make it once a few years ago and very stupidly as it was boiling wondered if it tasted ready and put my finger in the pot. It was sooo painful I burnt the entire tip of my finger, and since then was always a bit scared to make it again.

I originally thought that once I had made my shortbread I could just use Carnation Caramel on top but once the chocolate sets on top and you try and cut it into squares the caramel would just all splodge out the sides and that wasn’t the look I was going for. So while I was at work I happened to be talking to my colleague about baking and he suggested trying this recipe and it was perfect. The caramel only uses three ingredients and it sets perfectly when you cut the millionaires shortbread into individual squares the caramel doesn’t move or splodge out the sides it is also soooooo delicious and sweet.

The shortbread is also quite simple. Living in Scotland I grew up surrounded by shortbread so I had to make it properly. Its quite simple to make just like the caramel the only rule you need to remember is that it is one part sugar, two parts butter and three parts flour. So start with your sugar in this recipe I used 75g then I doubled this to get the butter 150g and triple it to get the flour quantity 225g. Shortbread should be ultra sweet and crumbly when you first take it out of the oven but it will firm up once it has cooled. When it has baked it should be white or a very light golden brown, you don’t want to overcook it or cook it at too high a temperature.

I LOVE quite a chunky biscuit if you don’t like the biscuit so thick you can reduce the quantities to make it slightly thinner. I also had quite a thick caramel layer but let’s be honest caramel is deeeelicious why wouldn’t you want a thick layer of it? Again you can reduce the quantities. The only thing I would change when making this recipe again is I would use 400g of milk chocolate just because the chocolate layer seems quite thin, so doubling the chocolate would make the layer thicker and more similar to the shortbread and the caramel.


This recipe makes 12 squares.
