How To Make Peanut Butter Millionaire Shortbread
To make the shortbread base you only need four ingredients. Flour, sugar, butter and peanuts. The peanuts are of course optional. Mix all four ingredients together until a dough is formed and press it into the base of your square tin. That’s it. That is all you need to do to make a delicious shortbread. It is so easy and simple.
For the shortbread in this recipe, I used caster sugar, but if you wanted it to have a slight hint of caramel flavour you could substitute this for light brown sugar. I find it easier to cream together the butter and sugar first and then add in the flour and peanuts, but you could do the all-in-one method if you prefer.
Like with my other millionaire shortbread recipes, I used a square 9”x 9” loose-bottomed cake tin. I just find it so much easier to get the millionaire shortbread out at the end. It is also the perfect size for millionaire shortbread. You get lovely thick shortbread and caramel layers.
I find the easiest way to get the shortbread base into the cake tin, is to press it in using either the back of a spoon (just dip it in some flour to stop it from sticking) or by using my hands.
You will know it is baked when it is golden in colour around the edges.
I don’t normally wait for the shortbread to cool completely before I make my caramel. You can. But it’s not essential. Once the shortbread is out of the oven, I leave it to one side and make the caramel straight away.

Caramel can be a bit daunting but please make your own. If you use a shop-bought caramel, no matter how thick it is, it won’t set. So, the minute you cut into it, it will splodge everywhere. Also, you can’t add peanut butter to a shop-bought caramel.
Add all the ingredients to a saucepan and heat on a low/medium heat. Another thing with caramel is you need to use unsalted butter. It won’t set properly if you use a baking spread. I cut it into cubes and added them to the saucepan with the condensed milk, golden syrup, sugar and smooth peanut butter.
Stir the mixture continuously until the butter is completely melted and the sugar has dissolved. You don’t want it to start bubbling until the butter has completely melted so you need to keep it at a low temperature.
Once the butter is completely melted turn the heat up and stir continuously. It will start to thicken and turn a lovely golden caramel colour. Just remember to run your spatula around the sides as well as the bottom of the pot to stop it from catching. If you do find little brown specks, it is just the bits that have caught.
If you are struggling, or find that it is starting to catch, turn the heat down. It might just take a few extra minutes. The caramel will be perfectly fine to eat with the flecks in but if you want to you can run the caramel through a sieve before you add it to the shortbread.
Put the mixture into the fridge and let the caramel set. Once the caramel has set, remove it from the fridge, and melt the chocolate. You can either melt the chocolate in a bain-marie or in a heatproof bowl in the microwave. Pour it over the caramel. In a separate bowl, soften the peanut butter by heating it for 10-20 seconds. Drizzle it over the top of the chocolate and using a skewer swirl it into the chocolate.
Put the millionaire shortbread back into the fridge until the chocolate has completely set before cutting.
Commonly Asked Questions
How do you cut Millionaires Shortbread cleanly?
There are a few different ways to cut Millionaire Shortbread cleanly. The first is to leave the chocolate to set at room temperature rather than put it into the fridge. This just helps it set slightly softer which makes it easier to cut.
Another way you can cut Millionaire Shortbread cleanly is by warming up the knife before you cut into the shortbread. Do this by running the knife under hot water, drying it off and then cutting.
How long does Millionaires Shortbread last in the fridge?
If you store the millionaire shortbread in an air-tight container it will last in the fridge for around 2 weeks.
Alternatives
