Preheat the oven to 200℃/400℉ and line a baking tray with parchment paper or a silicon baking mat.
Grate parmesan cheese into a bowl. Use the fine setting.
Place small handfuls of cheese (around 1 tablespoon) onto the lined tray and put the end of the stick in the middle. Cover with a little more cheese so it melts over it and keeps it in plave.
Put a small pinch of toppings/flavorings onto the cheese discs.
Bake the parmesan lollipops for 3-4 minutes, until crispy and bubbling.
Allow to cool on the tray or remove to a cooling rack with a palette knife after a minute or two.
Notes
If you are using one topping only, mix it into the grated cheese in the bowl.
Do not leave the parmesan lollipops unattended in the oven, as they can turn quickly.
Store in an airtight container in the fridge and use within 5-6 days.
