My friend Tora and I have been making salted caramel millionaire’s shortbread for years – both of us are obsessed with salted caramel. But then I thought, there’s not many things in life that aren’t improved by a little peanut butter. So I did this. And it was good.
You can easily omit the salt from the caramel if you want as the peanut butter will most likely be a bit salty anyway. But if you are using it, always add your salt last and in tiny amounts, tasting as you go. You can always add more, but you can’t take it away if you add too much!
This is pretty rich, so I definitely suggest cutting it into small portions.
Peanut Butter Salted Caramel Millionaire’s Shortbread
For the peanut butter shortbread:
- 150g unsalted butter, softened
- 30g smooth peanut butter
- 1 tsp vanilla extract
- 75g caster sugar
- 225g plain flour
Heat the oven to 180C and grease and line a tin (approximately 25x20cm) with greaseproof paper. In a large bowl, cream together the butter, peanut butter, vanilla and sugar. You can use an electric whisk for this but if your butter is nice and soft then it won’t take much work with a wooden spoon. Once well mixed, add the flour and rub it in with your finger tips until it’s the consistency of bread crumbs. Tip the mixture into your lined tin and squash and press it down and into the edges of the pan until you have an even layer – use your knuckles or the bag of a large spoon. Prick it all over with a fork and put it in the oven. Bake at 180C for 5 minutes, then turn down to 150C and bake for a further 30-35 minutes until evenly golden brown. Remove from the oven and cool a little before you’re ready to apply the caramel.
For the peanut butter salted caramel:
- 200g unsalted butter
- 397g condensed milk (that’s the standard size in the UK. It wont matter if it’s a few grams more or less)
- 4 tbsp golden syrup
- 2 tbsp smooth peanut butter
- up to 1 tsp sea salt
You can make the caramel whilst the shortbread is in the oven. In a medium sized heavy bottomed saucepan, melt the butter over a medium heat. Once the butter is melted add the condensed milk and golden syrup and continue to heat, stirring all the time with a wooden spoon. Seriously, don’t be tempted to leave this and do something else – the high sugar content means that it can easily catch and burn – I’ve made that mistake in the past and it’s frustrating and a waste when you have to chuck a batch of burnt caramel away, not to mention the mess it makes of the pan. Cook for about 10-15 minutes, hot enough to boil but not vigorously, and be careful as you don’t want to get splashed with it as it’s super hot. The caramel is ready when it’s, well, caramel coloured. Remove from the heat and stir in the peanut butter. Before adding any salt, taste a little bit (blow on it first and be very careful not to burn your tongue). Add the salt a pinch at a time, tasting after each addition. Once you’re happy with it, pour it over the cooked and slightly cooled shortbread. Spread it out with a spatula until it’s reached the edges and you have an even layer. Leave it to cool, or even put it in the fridge to set up a bit before you add the final layer of chocolate.
For the chocolate:
- 200g milk chocolate
- 100g dark chocolate
(To be honest, it won’t matter if you just use milk chocolate, but I prefer a mix of milk and dark) Melt the chocolate, either in a bowl over a pan of simmering water, or in short, 20 second bursts in the microwave, stirring in between zaps.
Once melted, pour over the shortbread and spread it to the edges. Give it a shake and a sharp rap on the kitchen counter to get a nice even finish. Leave to set in the fridge for at least a couple of hours. Remove from the pan, peel off the greaseproof paper and use a big sharp knife to cut into portions (I got 32 pieces out of this). This should keep well for 3-5 days in an airtight container, but I doubt it’ll last that long once anybody tries it!
