• Pre-heat your oven to 175oC.
• Line a 2lb loaf tin with baking paper.

Vanilla Layer

• Place the spread into a pan on a low heat, until its fully melted. Set aside to cool.
• Place the eggs and sugar into a mixing bowl.
• Add about 1 inch of water to a saucepan. Bring to a simmer. Once the water is simmering, place the mixing bowl ontop of the saucepan.

  >Make sure the base of the mixing bowl doesn't touch the water otherwise it'll cook and scramble the eggs!
  
• Whisk the egg and sugar together whilst on the pan for exactly 20 seconds.

  >The idea is to melt the sugar. You can use a hand whisk or an electric whisk at this point, whatever feels easiest to use whilst over the cooker.
• Remove the bowl from the pan and place it on the worktop. Whisk until its thick and airy. When you lift your whisk, it should form ribbon patterns in the mixture, which will hold their shape for around 3-5 seconds.

  >I always find it a little scary to judge when its at the perfect consistency, so its helpful to time it. It takes 4 mins with an electric whisk on full speed to get the consistency I'm looking for.
  
• Sift the flour over the egg mixture and FOLD in with a spatula/large spoon.

  >Don't use the whisk as you'll lose all that lovely air!!

  >There's a great video for how to do this, I've added it in the "tips" section of the blog post above. My tip: if you lean your bowl to one side (like the pic) and repeat the folding action, you can see if there's any sneaky flour that is still sitting at the bottom of the bowl.
  
• Pour the melted butter into the bowl and repeat the folding action until its fully incorporated.

  >Tip: lean the bowl to the side again.
  
• Gently pour the mixture into your loaf tin and place into the oven for 13 mins.

  >To test if its cooked, press the lightly on the top of the cake and it should spring back :)
  
• Remove from the oven, lift the cake out of the loaf tin, remove the baking paper and leave to cool on a cooling rack.

  >This is one of very few cakes that can instantly be removed from the baking tin as soon as its been taken out of the oven

Lemon & Raspberry Layer

• Repeat the steps above for the lemon and raspberry layer.

  Add the flavourings after step 5 (ie. whisk up the egg & sugar and then whisk in the flavourings & colourings using the electric whisk to ensure even spread of flavouring/colouring - its much easier than folding in at the end).

Italian Meringue Buttercream *need a candy thermometer*

• Add 3 tbsp of water and the caster sugar to a saucepan. Turn to a very low heat and keep stirring the mixture until the sugar has melted

  >You can tell when the sugar has melted by placing a spoon into the mix. When you lift out the spoon, there shouldn't be any visible grains of sugar visible.
• At that point, leaving the pan on the heat, whisk the egg white until they reach soft peaks.
• Increase the heat of the sugar/water solution so it starts to boil. Leave (don't stir) until it reaches 120°C/250°F on your cooking/candy thermometer.
• Slowly pour the sugar solution into the egg white, whisking at high speed constantly.

  >Try to avoid pouring the hot sugar onto the sides of the bowl as it will instantly cool and get stuck there.
• Add 1 tbsp of butter/spread to the mixture and whisk in. Repeat for the rest of the butter.
• Place into the fridge/freezer to chill and firm up.

  >Ideally, leave it for at least 15 mins in the freezer.

Alternative

• Mix the icing sugar with a tiny dash of water until really thick.

Construction

• Once all 3 layers of cake are completely cool, layer them with the icing and stack them up!
• You can then either (1) dust the top with icing sugar or (2) combine a little icing sugar with water and drizzle over the top. Then, make a small amount of pink icing sugar and drizzle in lines over the top of the white (along the short sides). Drag a toothpick lengthways (opposite direction to your pink lines) along the cake to create the feathering .
