Millionaires Cake!

Three Layer Caramelly Sponges with Chocolate Buttercream Frosting, Gooey Caramel, and Mini Shortbread Bites make the BEST Millionaires Cake Ever!

So I adore anything Millionaires themed… how can I not?! Biscuit, caramel and chocolate is THE BEST COMBINATION. Ever. Honestly, I love it! My Millionaires Cupcakes post has been so popular since I posted it; I adore the secret caramel centre, with the naturally caramelly sponge and chocolate buttercream on top. The photos look so good on that post because they show the caramel oozing out so it never surprises me that they’re a hit!

My Salted Caramel Millionaires Shortbread has always been a massive hit as well because its a salty twist on the classic. I adore it! I love the salted caramel, which you can easily add to this recipe as well. You could simply add a tsp of salt to the tin of caramel, and it would be delicious!

With this recipe, I did base it quite heavily on my Millionaires Cupcakes as I adore it so much. I used the Light Brown Sugar recipe again as I just adore the flavour of the sponges, and it keeps it so moist and lovely. I then went with an easy Chocolate Buttercream frosting using Cocoa Power, but you can easily swap to using actual chocolate if you wanted instead.. I simply use whatever I find easier sometimes (and whatever I have in the cupboard!)

I went for a big three layer cake as I just love the look of them, and it certainly makes them a showstopper. However, if you want to make a smaller cake, then the details are in my Tips and Ideas section below. You can using whatever caramel you like, or even swap it to a caramel buttercream, but chocolate drizzled on it instead! But honestly, this is one of my favourite bakes in a long time and I hope you all love it too! Enjoy! x

Ingredients

Cake Ingredients

  • 400 g Unsalted Butter/Stork
  • 400 g Light Brown Sugar
  • 8 Medium Eggs
  • 400 g Self Raising Flour
  • 2 tsp Baking Powder

Chocolate Buttercream Frosting

  • 350 g Unsalted Butter (room temp)
  • 650 g Icing Sugar
  • 75 g Cocoa Powder
  • 1-2 tbsp Boiling Water

Decoration

  • 350 g Caramel (carnations)
  • Shortbread Bites
  • Sprinkles
  • Crushed Shortbread

Instructions

For the Cake!

  • Heat the oven to 180C/160C Fan and line three 20cm/8inch sandwich cake tins with baking parchment – leave to the side.
  • In a stand mixer, beat together the butter and light brown sugar for a few minutes until light and fluffy. Add in the flour, eggs, baking powder and beat again briefly till combined – try not to overbeat!
  • Divide the mixture between the three tins and smooth it over – bake for 25-30minutes until the cakes are golden and when the cake springs back (skewer should also come out clean)!
  • Once baked, leave the cakes to cool in their tins for 10 minutes or so, and then remove and leave to cool fully on a wire rack. If the cake has domed slightly, leave the cake to cool upside down to flatten it slightly so its easier to decorate later!

For the Decoration!

  • Beat the butter with an electric mixer for a couple of minutes to loosen it – Gradually add the icing sugar on a slow speed until it is combined then speed the mixer up and mix for 3-4 minutes until thoroughly combined and smooth.
  • Add the Cocoa Powder to the buttercream and continue mixing. If its really stiff, add in 1tbsp of Boiling Water at a time until you reach the desired texture.
  • When its summery I don’t usually need to add any, when its colder weather its usually 1-3tbsps! Keep on beating for 5 minutes until whipped and silky smooth!
  • On the first layer of the cake, pipe your buttercream using a 2D Closed Star Piping Tip, and then drizzle/spread some of the caramel on top. Repeat again with the next layer.
  • For the top layer, pipe on the rest of the buttercream, and add some little swirls. Drizzle over some more caramel. On top of each swirl, add a mini Millionaires Shortbread Bite, or a piece of Shortbread. 
  • Sprinkle on some crushed shortbread, some sprinkles, and ENJOY!

Notes

  • I love this style of cake as you can tell from the few I have made, and I happen to have 3 8″ tins, if you don’t have 3 tins you can make a smaller version of the cake, use 300g of everything in the cake mixture rather than 400g, 1.5tsps of baking powder, 6 medium eggs (and it might take an extra 5-10 minutes to bake) and use 2/3 of the decoration recipes!
  • I used Carnations Caramel which is like the condensed milk you can buy, but you can realistically use any caramel sauce you like or Dulce de Leche.
  • This cake will last in an airtight container for 3 days!

    Hi, if i was to use 3 x 6 inch tins would the recipe be the same as the smaller recipe using 2 x 8 inch tins?

      So for a 6″ version I usually say to use about 2/3 of a recipe – so you can use the smaller version if you want but I’m not 100% sure on timings!! x

    Hi, my son has picked this recipe for me to try for his birthday cake this year! I can’t wait to taste it myself as it looks amazing! However, on the day I need it I will be short of time, so am planning to bake the cake the day before and then decorate on the day. Would the butter cream be ok to pipe the next day if I made it the day before too? Just trying to save as much time as possible. Thank you x

      You would need to re-mix the buttercream to freshen it up to be able to pipe it again – You could definitely do the sponges the day before, but personally (unless you don’t mind the re-mixing) would make the buttercream on the day! X

    Looks amazing !! Thinking of making this. When you say ‘light brown sugar’ do you mean caster sugar?

      No, light brown sugar is a soft brown sugar. It’s not caster, muscavado or Demerara – it’s just light brown sugar x

    Do we pipe all over the cake with the buttercream.

    Hi Jane,
    Another fantastic creation! Can I ask why the addition of baking powder to this cake recipe? Normally you make your sponge without.

      I have several recipes with baking powder, not just this one – and I find it just lightens the texture! You can leave it out if you want x

    Did you melt the caramel and then drizzle it?

      I don’t melt it, no. I just mix it a little in a bowl or the tin and then drizzle x

      Hi Jane.
      I made this cake for my son for his birthday. The sponges came out lovely, but the butter cream so was thick. I did everything precisely as per recipe, but it was that thick I couldn’t pipe it! In the end after a couple of attempts at re mixing it, I gave up and just had to smooth it onto the sponges, which spoilt the affect. Help….what did I do wrong?

      You just need to add a little boiling water or whole milk to thin a buttercream out if it’s too thick xx

      You use about 2/3 of the recipe, and follow the method, but baking time is shorter x

      This looks insanely good !! In your notes where you talk about adapting the recipie to make a smaller version, how many tins was that in reference to w.g. was it for 2 x 8 inch tins ?

    I live in the US and I am wondering what the difference is between the flour in the UK and our flour. I believe that our “self RISING flour” is different than your “self RAISING flour”. Would you happen to know what I need to use in place of, or in addition to, our regular all-purpose flour to achieve the right texture for this cake? I love your creations and I cannot wait to make this cake!!

      I believe your all-purpose flour is the same as our plain-flour. For this cake, I would add in probably 3tsp more baking powder. x

      Yes – the cakes won’t be that deep so they’d be fine.

      July 25, 2017 at 9:39 pm

      Sorry I missread that ? did you mean one tin? It should be fine but I’d lower the baking temperature to 140C and bake for a long time.
