Preheat the oven to 400F (200C).

Prepare the base by melting the shredded cheese in the microwave. It only needs a minute or so on high power.

Next, add the cream cheese, eggs, pork rind crumbs, and onion powder to a stand mixer bowl. Add the melted cheese and blend until as smooth as possible. It will look more like a batter than a dough.

Line a baking sheet with a silicone mat and spray with no-stick spray. Transfer the mixture to the pan, and smooth into a circle or rectangle.

Bake in the oven for 12-15 minutes, rotating half way through the cooking time if necessary for even cooking.

If you have your toppings ready, add them now and return to the oven for 5 minutes or until everything is warmed through and the cheese has melted.

If saving for later, leave until cool then cover the whole tray in foil and place in the fridge. When ready to reheat, place under a hot broiler for 5 minutes. Add the toppings, return to the broiler and cook until warmed through.
