Prepare focaccia dough according to recipe instructions up until the point where it's time to transfer to baking tray
Oil muffin tin liberally with extra virgin olive oil
Add 50g of focaccia dough to each compartment of the muffin tin
Cover with inverted tray and let proof at room temperature for 1.5 hours
Prepare toppings and garlic butter
Preheat oven to 215C/420F
Spoon garlic butter over each and dimple dough using two oiled fingers (dimple 3-4 times for each compartment)
Add a spoonful of pizza sauce to each
Add on a few pizza toppings, some grated mozzarella cheese, more toppings and then dimple all of the toppings into the dough
Sprinkle some extra mozzarella over each mini pizza
Place muffin tin on large baking tray and bake on lowest rack in oven for 16-20 minutes until cheese is golden brown and toppings are crisping up
If cheese is starting to brown too much before the bottoms are crisp, then just tent some foil over the top for a few extra minutes
Once the mini pizzas are out of the oven, brush on additional garlic butter and a sprinkle of freshly Parmesan to finish
You may need to pry out of tin with a knife, the baked cheese will stick to the tin
