Salted Peanuts & Peanut Butter Millionaire’s Shortbread

Salted Peanuts & Peanut Butter Millionaire's Shortbread

There is not much to say about my second Great British Bake Off inspired creation as it pretty much speaks for itself. Millionaire’s Shortbread is pretty much a classic and as much as I love it I decided to tinker with it a tiny bit. Tablespoon of peanut butter here and there, sprinkling of some salted peanuts, et voilà, Salted Peanuts & Peanut Butter Millionaire’s Shortbread! 

I decided to be really careful with peanut butter cause as much as I love it, I still wanted to keep the essence of the caramel flavour itself. I think my attempt worked really well and you get enough salty deliciousness from peanut butter and peanuts but also some lovely caramel sweetness. Not to mention hint of vanilla coming through from the shortbread as I used my favourite of late, vanilla sugar. I’ve written about Vanilla Sugar How-To! here

I must admit I have cheated a bit with my caramel and went for the version that uses condensed milk but I do prefer it like that. Do not expect to achieve the same colour as you would if you were to make it the traditional way. When it comes to doneness look for thickening consistency and not the colour to guide you.

As a final touch I decided to add a handful of salted peanuts sprinkled over the caramel for a bit of unexpected crunch! And…bit more peanut butter to the chocolate topping itself to create pretty swirls I was quite happy with (little things). πŸ˜‰

Finally, onto the recipe itself!

Salted Peanuts & Peanut Butter Millionaire's Shortbread

Yield: 16 squares


  • 175g plain flour
  • 125g unsalted butter (cold)
  • 50g vanilla sugar or caster sugar
  • 150g unsalted butter
  • 150g light brown sugar
  • 397g tin condensed milk
  • 1 generous tbsp peanut butter
  • 50g salted roasted peanuts
    Chocolate topping
  • 100g milk chocolate
  • 100g dark chocolate
  • 1 generous tbsp peanut butter
    Square baking tin approx 23x23cm or equivalent


  1. Put flour, sugar and butter into food processor and mix until you start getting sand/crumbs like consistency. Mix for a bit longer until it starts to look more like a dough. You can also do it by hand if you prefer rubbing cold butter together with mixed flour and sugar.
  2. Tip the mixture onto baking tray lined with greaseproof paper and press the dough with your fingers until it covers the bottom of the pan.
  3. Bake in 180C for approx. 25min, until light golden. Leave to cool slightly
  4. Put sugar and butter in a saucepan and heat up gently until dissolved.
  5. Add condensed milk and peanut butter and mix well.
  6. Bring mixture to boil and keep stirring for about 10 minutes until it thickens and darkens slightly in colour (this caramel will be much lighter though).
  7. Pour caramel over cooled shortbread and sprinkle over salted peanuts. Set aside to cool slightly.
  8. Melt chocolate gently in a bowl set over the pan of simmering water until shiny and smooth and pour it over the caramel layer, smoothing out gently with a spoon.
  9. Heat the peanut butter in a microwave until runny and drizzle over the chocolate. Swirl together with a toothpick to get pretty, marbled effect!
  10. Chill in the fridge for at least couple of hours or until firm.
  11. Cut into 16 squares or as per your tin and enjoy!

    Your recipe uses similar flavours to the one I did, I’m glad I’m not the only person who saw the need to add peanut butter to it! These look really delicious and I love the marbling on the top x

    Oh my lord, this looks so good. The peanut butter sounds like a brilliant addition as I usually find MSB a bit on the sweet side. Thanks for sharing with #WeShouldCocoa.

      Thank you! Lovely to be back! I know what you mean hence salted peanuts and peanut butter which mellowed the sweetness nicely without going full on salted caramel.

      Thanks Jenny! πŸ™‚ I love peanut butter too, way too much! It really works nicely here and it is subtle enough at the same time. It’s salty peanuts though what makes it for me here, absolutely delicious together with sweet caramel! x
