Preheat oven to 375°F. Line a sheet pan or two with parchment paper or silpats. Place dowels or chopsticks between two jars or over a bowl that supports both ends.

Arrange piles of cheese with at least 4 inches of space between them to allow for spreading. When the cheese is fully melted, brown around the edges and 2/3 of the way to the center. Immediately transfer onto dowels using a slotted spatula. Allow gravity to pull the sides down. Cool completely before stuffing.
