Cut the bread into eight 1-inch thick slices. Carefully cut a pocket in the long side of each piece, about ¾ of the way through. (Use a serrated knife).
Combine cream cheese and preserves thoroughly. Stuff each pocket with about 2 tablespoons filling, then pat pocket flat with your fingers.
Preheat Cuisinart™ Electric Skillet to 300°F. Mix eggs and half-&-half well and add vanilla; stir. Pour batter into a 9x13-inch baking pan. Soak 4 filled slices of bread for at least 10 minutes, turning several times. (Let the remaining 4 slices soak in the batter while the first batch cooks.)
Melt 2 teaspoons butter in the Skillet and cook 4 slices at a time, for about 6 to 8 minutes a side, or until nicely browned. Remove and keep warm on a rack in a 200°F oven. Melt the remaining 2 teaspoons butter and cook second batch.Serve with maple syrup, raspberry syrup or powdered sugar.
