Ingredients

Units Scale
  • 350g baking spread (or softened butter)
  • 350g caster sugar
  • 6 large eggs
  • 325g self-rising flour
  • 2 tsp vanilla extract
  • Pink food colouring
  • 1/2 tsp baking powder
  • 35g cocoa powder
  • 50g dark chocolate, melted
  • 100g unsalted butter, softened (for buttercream)
  • 200g icing sugar (for buttercream)
  • 2 1/2 tbsp milk (for buttercream)
  • 1 tsp vanilla extract (for buttercream)
  • 2 tbsp cocoa powder (for buttercream)

Instructions

  1. Preheat oven to 180°C (350°F). Grease and line a loaf tin.
  2. Make the pink heart sponge: Beat together 175g baking spread, 175g caster sugar, 3 eggs, 1 tsp vanilla extract, 162g self-rising flour, and pink food colouring until smooth. Pour into loaf tin and bake for 25 minutes. Let cool, then cut into slices and use a heart-shaped cutter to make pink heart pieces. Set aside.
  3. Prepare the chocolate cake batter: Beat remaining baking spread and sugar with remaining eggs, 1 tsp vanilla, remaining flour, cocoa powder, and baking powder until smooth. Stir in melted dark chocolate.
  4. Spoon a little chocolate batter into a greased loaf tin to cover the base. Line up pink heart cutouts in the center. Carefully cover with remaining chocolate batter, making sure the hearts are fully enclosed.
  5. Bake for 45–50 minutes at 180°C (350°F), or until a skewer inserted comes out clean. Let cool completely.
  6. Make the buttercream: Beat softened butter until creamy. Gradually add icing sugar, cocoa powder, vanilla extract, and milk. Beat until smooth and fluffy.
  7. Spread or pipe the buttercream over the cooled loaf cake.
  8. Decorate with heart-shaped sprinkles and slice to reveal the hidden heart center.

Notes

  • Use gel food coloring for a vibrant pink sponge.
  • Ensure pink hearts are lined up tightly to maintain shape during baking.
  • Let the cake cool completely before frosting to avoid melting the buttercream.
  • Store in an airtight container for up to 3 days.
