Lay 1 slice of bread on a work surface. Spread one side with 1 teaspoon of the butter. Repeat with the remaining bread slices and butter.

Turn 2 bread slices over so the buttered sides are down. Top the slices with the cheese slices, dividing them evenly.

Lay 4 pickle slices on top of each stack of cheese. Top with the other 2 bread slices, buttered sides up.

Place the sandwiches in a skillet. Set the skillet on the stove and switch on the heat to medium. Cook the sandwiches until golden brown on the underside and the cheese begins to melt, about 3 minutes. To check, lift up a corner of a sandwich with a spatula and peek underneath. Using the spatula, flip over both sandwiches. Cook until golden brown on the second side and the cheese has melted, about 3 minutes longer.

Use the spatula to transfer the sandwiches to a cutting board. You can cut your sandwiches into stars or planets if you have a star-shaped or round cookie cutter. Press the cookie cutter straight down into the sandwich. Be careful not to burn your fingers on the hot cheese. Lift the cutter gently. Repeat with the other sandwich. Serve the sandwiches immediately.
