Pre-heat the oven to 375 degrees. Line a baking sheet with parchment or a silicon baking sheet (silpat). Mound the cheese in four even piles about 1/4 cup for each, using your finger to spread the cheese out into 4-inch (in diameter) circles. Bake the cheese until it’s melted, bubbling and slightly browned, about 5-7 minutes. Remove from the oven and let cool for a few seconds. Using a thin spatula, slide them off the baking sheet. Using an empty muffin tray, fill the tin with the warm cheese. Let the frico cool in the muffin tin, they will take on the shape of cups.
