For the red sponge
- 125 g (4oz) unsalted butter, softened, plus extra to grease
- 125 g (4oz) caster sugar
- 2 large eggs, beaten
- 125 g (4oz) self-raising flour
- 1/2 tsp. red food colouring paste (we used Squires Kitchen food paste in Poinsettia)
For the plain sponge
- 175 g (6oz) unsalted butter, softened, plus extra to grease
- 175 g (6oz) caster sugar
- 3 large eggs
- 1 tsp. almond extract
- 175 g (6oz) self-raising flour
- 1/2 tsp. baking powder
For the buttercream
- 50 g (2oz) white chocolate, chopped
- 125 g (4oz) unsalted butter, softened
- 250 g (9oz) icing sugar
- 1-2tbsp milk
- sugar heart sprinkles, to decorate, optional
You will also need
- 4.5cm (13/4in) heart cutter
- Step 1
For the red sponge, grease and line a 20.5cm (8in) square cake tin with baking parchment. Preheat oven to 180°C (160°C fan) mark 4. In a large bowl, beat butter and caster sugar until light and fluffy. Gradually add the eggs, beating well after each addition.
- Step 2
Sieve over flour and gently fold into butter mixture. Stir in food colour, then spread the batter into the tin and bake for 15-20min or until a skewer inserted into the centre comes out clean. Cool in the tin on a wire rack, then freeze for 20min to firm up.
- Step 3
When the red cake is cool, remove from tin and press down lightly to compact the sponge. Cut out heart shapes using a 4.5cm (1¾in) heart cutter. (You’ll need about 9 hearts, but cut a few extra.) Put hearts on to a baking tray and put into the freezer to firm up while you make the loaf cake. Grease a 900g (2lb) loaf tin, then line the base and sides with a strip of baking parchment.
- Step 4
For the plain sponge: in a large bowl, beat butter and caster sugar until light and fluffy. In a jug, beat the eggs with the almond extract, then gradually add to the butter mixture. Sieve over self-raising flour and baking powder. Fold into the butter mixture.
- Step 5
Spoon a third of the cake mixture into the tin to cover the base. Remove red hearts from the freezer. Gently and carefully press the neatest ones vertically into the centre of the cake mixture so they fit snugly in a line, leaving a small space at either end for plain sponge batter. Make sure to press the hearts together so there are no gaps. Carefully spoon the remaining plain sponge mixture into the tin. Bake for 45-50min, then leave to cool in the tin.
- Step 6
For the buttercream, gently melt white chocolate in a bowl set over a pan of barely simmering water. Set it aside to cool. Beat the butter until light and fluffy, then gradually add the icing sugar until it is all incorporated. Add the cooled white chocolate and enough milk to make it spreadable. Remove cooled loaf from tin. Spread the icing on top of the loaf cake and sprinkle with heart sprinkles, if you like.
