How to fill cupcakes

1. Cut off the top of the cupcake in the shape of a cone using a small paring knife. Cut the pointy part off to make it flat (so the top will fit back into the cupcake nicely once filled with frosting)

2. The top that you have cut off the cupcake should resemble a cone.
3. Fill the hole with filling either using a spoon or by piping it in (in this case it is nutella frosting).

4. Carefully pop the top back on the cupcake securely.
