With a small sharp knife open a small hole in the centre of the cupcake and lift it.
Fill the hole with the filling of your liking – I used raspberry jam here.
Cut the top of the core off to make a lid.
Spread the topping of your choice – I used Nutella.
Using a cupcake corer speeds the process. Insert it into the centre of the cupcake and pull it back twisting the corer.
