Slice the Brie cheese into thin pieces to ensure even melting during cooking.

Spread softened butter on one side of each slice of sourdough bread. This will create a golden, crispy crust when grilled.

On the unbuttered side of 4 slices of bread, spread a generous layer of apple butter.

Layer the sliced Brie cheese on top of the apple butter, ensuring even coverage.

Top with the remaining 4 slices of bread, buttered side facing out.

Heat a skillet over medium heat. Once hot, place the assembled sandwiches in the skillet.

Cook for about 3-4 minutes on one side, or until golden brown. Press down gently with a spatula to ensure even cooking.

Carefully flip the sandwiches and cook for an additional 3-4 minutes on the other side, until the bread is golden and the cheese is melted.

Remove the sandwiches from the skillet and let them cool for a minute before slicing in half.

Serve warm, optionally with extra apple butter on the side for dipping.
