Overnight Blueberry-Lemon-Cream Cheese French Toast

Lightly butter 13 x 9-inch (3-quart) baking dish.

In medium bowl, beat cream cheese, 3 tablespoons of the sugar, and 1 tablespoon of the lemon peel with electric mixer on medium speed until smooth and creamy. Generously spread mixture over 5 slices of the challah. Press a few blueberries onto cream cheese; place another slice challah on top of each to make cream cheese and blueberry sandwiches. Place 4 of the sandwiches in baking dish. Cut remaining sandwich into pieces to fill in any gaps between the ones already in the dish.

In large bowl, beat eggs, remaining 3 tablespoons sugar, remaining 1 tablespoon lemon peel, the milk and cream with whisk. Pour mixture over challah in casserole; top with remaining blueberries. Cover with plastic wrap; refrigerate at least 1 hour but no longer than 12 hours.

Take dish out of refrigerator about 30 minutes before baking to take the chill off. Heat oven to 350° F. Bake about 40 minutes or until puffed and golden. Cool on rack 15 minutes before serving.
