Top Tips To Make Millionaire Shortbread

  • Wait for the caramel layer to cool completely before topping with chocolate. If you’re impatient, the heat from the caramel will travel through the chocolate, create moisture and probably cause your chocolate to bloom. (Get white streaks.) Which there is no coming back from.
  • Invest in a sugar thermometer. It’s possible to gauge caramel by eye but that’s no real substitute for an actual thermometer. Once it has hit 107°C you know it will set, go as high as 120°C and it will be completely solid, take it to 115°C and it will be just perfect! The colour difference between those temperatures is quite minimal though which is very difficult to judge by eye. Go on, treat yourself. They’re only £2-3!
  • Once you start your caramel, don’t walk away. If you don’t stir constantly when it’s boiling it will catch very quickly on the bottom and burn. Not what you want! It will take around 10-15 minutes to bring it to the right temperature so bear this in mind before you start that step.
  • Have your peanuts roughly chopped before you start the caramel layer. Caramel starts to set quite quickly once taken off the heat so have your peanuts chopped and ready to stir through immediately to avoid any disappointment.

Snickers Millionaire Shortbread Recipe

Here’s what you will need to make 16 bars.

For the Biscuit Base

  • 100g (1/2 Cup) Unsalted Butter, Room Temp
  • 40g (1/4 Cup) Golden Caster Sugar
  • 120g (1 Cup) Plain Flour
  • Pinch of Salt

 

For the Caramel

  • 160g (5.6 oz) Condensed Milk
  • 100g (1/2 Cup) Unsalted Butter, Room Temp
  • 100g (1/2 Cup) Soft Light Brown Sugar
  • 2 tbsp Golden Syrup
  • 1 tsp Vanilla Extract
  • Pinch of Salt
  • 100g (3.5 oz) Peanuts, Roughly Chopped

 

For the Topping

  • 200g (7 oz) Milk Chocolate
  • 30g (1/8 Cup) Smooth Peanut Butter

 

Essential Equipment

  • 20cm (8″) Baking Tin
  • Sugar Thermometer (Possible without but far easier with!)

 

Grease and line the base and sides of your baking tin and preheat the oven to 180°C/Fan 170°C.

To Make the Biscuit Layer

In either an electric stand mixer or a large bowl with an electric hand whisk, cream together the butter and sugar until light and creamy.

Then add in the flour and salt. Give it another brief mix until it just starts clumping/forming a dough.

Tip the biscuit dough into your prepared tin and press down evenly into the bottom. Finally, poke all over with a fork then pop into the preheated oven to bake for 15 mins until lightly golden.

Leave to one side to cool while we make the caramel.

To Make the Caramel Layer

First thing’s first, make sure you have your peanuts chopped and ready before starting your caramel.

Weigh all the caramel ingredients (except the peanuts) into a large heavy based saucepan and place over a medium heat.

Stir often until everything is runny and dissolved.

Bring the caramel to the boil and stir constantly & vigorously. If you don’t, it can quickly catch and burn on the bottom of the pan.

Keep boiling and stirring until the mixture reaches 115°C on a sugar thermometer. You can try and judge it by eye (stop when it’s a light caramel colour) but it’s fairly difficult. Once the temperature is reached, turn off the heat and keep stirring until the caramel stops bubbling. This is just to avoid any scorching – it will continue cooking as the pan will still be very hot.

From start to finish, the caramel should take no longer than 10-15 minutes.

Tip in those chopped peanuts straight away and give it a stir.

Time to pour that caramel over your biscuit base.

Smooth out as best as you can with a spatula then set to one side to cool completely before making the topping. I do mean COMPLETELY. If you’re impatient, you’re chocolate may bloom (have white streaks) and could ruin all your hard work!

To Make the Chocolate Topping

Once your caramel is completely cooled, it’s time to make the chocolate layer!

Break the chocolate into a microwavable glass bowl and add in the peanut butter.

Switch your microwave to half power then heat the mixture in 10 second intervals, stirring really well with a spatula after every time.

Continue until it’s two thirds melted then don’t heat anymore – just stir continuously until it’s completely melted and smooth. A good gauge is to keep the glass bowl itself as cool to the touch as possible so the heat doesn’t transfer to the chocolate. So no long bursts in the microwave, just short bursts so you can keep full control of the temperature of your chocolate!

Now you’ve tempered your chocolate, pour and spread it all over the top over your caramel.

You can leave it at that, but if you’re feeling fancy you can create a pretty pattern on the top. I dipped in the end of a small spatula then lifted up – moved forward and dipped again, continuing all the way along in rows across the top.

Allow to set at room temperature (don’t put in the fridge or you may lose that lovely tempered chocolate shine!) before slicing into 16 pieces with a sharp knife.
