Prepare a 9 x 13-inch baking dish by spraying it with cooking spray.
Divide the cream cheese into 6 cubes. Spread one cube of cream cheese onto the top of one waffle and place it in a single layer in the bottom of the prepared baking dish, cream cheese side up.
Repeat with remaining cream cheese and 5 more waffles.
Place remaining 6 waffles on top so that it resembles 6 waffle sandwiches.
In a medium bowl, beat eggs. Add milk and syrup and mix well.
Using a ladle, pour mixture evenly over the waffles, making sure each is well coated.
Cover baking dish tightly with plastic wrap and refrigerate for 30 minutes.
Remove from fridge, and using a metal spatula, flip the waffle sandwich over. Replace plastic wrap and place back in the fridge overnight.
In the morning, preheat oven to 375 degrees. While oven is warming, in a small saucepan, combine butter and brown sugar.
Heat over medium-high until butter is melted and sugar is dissolved. Pour mixture evenly over waffles.
Bake for 25-30 minutes until middle is set. Allow waffles to stand for 10 minutes before serving. Garnish with sliced strawberries.
