Instructions
1. Prepare the Pink Heart Sponge:

- Once baked, allow the cake to cool in the tin for a few minutes before transferring it to a wire rack to cool completely.
2. Create the Heart Shapes:
- Once the pink sponge has cooled, slice it into pieces approximately 2cm (¾ inch) thick.
- Using a small heart-shaped cookie cutter, cut out heart shapes from each slice. Set these hearts aside.
