Yes, you can use parchment paper on top of a cake that has jelly between the layers and has set overnight. Using parchment paper can help protect the jelly layer and prevent it from sticking to any covering or frosting you may apply on top.
Here's how you can use parchment paper to cover the cake:
- After the jelly has set overnight between the cake layers, ensure that the cake is completely cool and firm.
- Take a sheet of parchment paper that is larger than the size of the cake.
- Place the parchment paper gently on top of the jelly layer, making sure it covers the entire surface of the cake.
- Gently press down on the parchment paper to ensure it adheres to the jelly layer and stays in place.
- If desired, you can then frost or decorate the cake as you wish, directly over the parchment paper.
Using parchment paper will make it easier to frost or decorate the cake without disturbing the jelly layer underneath. Once you are finished frosting or decorating, carefully remove the parchment paper before serving the cake.
Remember to handle the cake and parchment paper with care to avoid any damage to the jelly layer or the cake itself.
