Ingredients
8sliceschallah bread,(from 1 loaf), or brioche, white, or Italian bread, ½-inch thick slices
4tbspsalted butter,softened
4ozsemisweet chocolate chips,(⅔ cup), or finely chopped chocolate, best quality such as Ghirardelli or Guittard
Preparation
Adjust an oven rack to the middle position and preheat the oven to 425 degrees F. Line a baking sheet with parchment paper for easy cleanup.
Spread one side of each bread slice with about 1½ teaspoons butter and place 4 slices, buttered side down, on the prepared baking sheet.
Spread about a ¼ of the chocolate chips evenly on each of the 4 slices, leaving a ¼-inch border around the edges. Cover with the remaining bread slices, buttered side up.
Bake for 7 to 9 minutes until the bottoms of the paninis are crisp and golden brown. Remove the pan from the oven. Using a metal spatula, gently press down on sandwiches to spread the soft chips into melted chocolate.
Carefully turn the sandwiches over and continue baking for about 5 minutes longer until the bottoms are crisp and golden.
Let cool slightly, cut paninis in half, and serve.
