• 2 large eggs
• 2 tablespoons milk
• 4 large slices challah or Italian bread, (cut 3/4 inch thick)
• 4 ounces thin semisweet chocolate bar
• 2 tablespoons unsalted butter
• Confectioners’ sugar, for dusting

In a large, shallow dish, whisk together eggs and milk; set aside.

Form two sandwiches with the bread and chocolate (break chocolate as necessary to cover bread without extending over edges); dip both sides of sandwiches in egg mixture to coat.

Heat butter in a large skillet over medium heat; transfer sandwiches to skillet. Cook, pressing occasionally with a spatula, until golden, 1 to 2 minutes per side. Transfer to a paper-towel-lined plate.

Cut in half, and dust with confectioners’ sugar before serving.
