Ingredients

For the pink sponge

  • 175 g Butter or baking spread
  • 175 g Caster sugar
  • 3 Eggs large
  • 1 tsp Vanilla extract
  • 175 g Self raising flour
  • Pink food colouring

For the chocolate sponge

  • 175 g Butter or baking spread
  • 175 g Caster sugar
  • 3 Eggs large
  • 150 g Self raising flour
  • 35 g Cocoa powder
  • ½ tsp Baking powder
  • 1 ½ tbsp Milk

For the buttercream

  • 100 g Butter
  • 200 g Icing sugar
  • 1 tsp Vanilla extract
  • 50 g Dark chocolate melted
  • 1 tbsp Milk

For decoration

  • Heart sprinkles optional

Instructions

  • Pre heat the oven to 160C Fan/180C/350F/Gas Mark 4 and grease and line a 2lb loaf tin
  • Make the pink sponge first. Mix the butter and sugar together until fluffy, ideally with an electric mixer, or you can mix in a bowl with a wooden or silicone spoon
  • Add eggs and vanilla extract and whisk in
  • Whisk in the self raising flour, and add enough pink food colouring to get a strong shade
  • Pour the mixture into the loaf tin and bake for around 50 minutes or until a skewer inserted in the centre comes out clean
  • Leave it to cool completely, then cut off the ends of the sponge, then score marks along it the same thickness as your heart shaped cutter
  • Cut the sponge into slices following the scored lines and then use your heart shaped cutter to cut out hearts from each piece
  • Make the chocolate sponge. Mix the butter and sugar together until fluffy, ideally with an electric mixer, or you can mix in a bowl with a wooden or silicone spoon
  • Add the eggs and milk, and whisk in
  • Whisk in the self raising flour, baking powder and the cocoa powder
  • Put some of the mixture into the bottom of the tin, and set the heart shaped pink cake into it neatly in a row
  • Spoon the remaining mixture around and on top of the pink sponge hearts, or you can pipe the cake batter in using a piping bag
  • Bake for around 50 minutes or until a skewer inserted in the centre comes out clean, allow to cool fully
  • To make the buttercream mix together the icing sugar, vanilla extract, milk and butter. Then add the melted dark chocolate and mix until smooth. If the buttercream is too stiff then you can add a little more milk
  • Spread or pipe the buttercream over the sponge and sprinkle on some heart sprinkles too if you like
  • Slice to reveal the hidden heart design! Store leftovers in an airtight container in a cool place for up to 3 days

Notes

  • Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
  • For the best flavour, make sure to use a good quality vanilla extract and not an essence.
  • I used a baking spread for the cakes and unsalted butter for the buttercream.
  • You will need to use a professional grade food colouring to get the same shade of pink that you can see in my photos. Brands I recommend are Pro Gel and Sugarflair. Colour Mill and Americolor are also good quality brands.
  • You will need a 2lb loaf tin for this recipe (you can test the size of your loaf tin by seeing how much water the tin can hold, 2lb will hold about 2 pints/1100ml of water). If you have a 1lb loaf tin, simply halve the ingredient amounts.
  • For easy lining of the tin, use a loaf cake tin liner*.
  • Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
  • For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
