Preheat the oven to 375° F. Grease a baking sheet with butter. In a large shallow dish, whisk together the eggs, milk, 2 tablespoons St. Germain, 1 tablespoon vanilla, and the salt. Grab the croissants and make a 1 inch slit at the top of each, move your knife to create space in the croissant, being careful not to poke through the other sides (see above photos). In a bowl, gently stir together the cream cheese and strawberry jam, leaving streaks of red and white. Spoon the mix into a ziplock bag and snip the corner off the bag. Squeeze approximately 2 tablespoons of the strawberry cream into each croissant where you created your hole. Don't stress about making it perfect. Dip each croissant into the egg mixture, allow it to sit 1 minute per side. Arrange half the croissants on the prepared baking sheet. Brush each croissant with a little leftover egg batter. Bake for 20-25 minutes or until the croissant is golden. Melt together the butter, brown sugar, and 2 tablespoons maple syrup. Spoon the butter evenly over each croissant. Bake another 10 minutes, until the croissants are caramelized on top and crisp.Toss the berries with 1 tablespoon St. Germain, 1 teaspoon vanilla, and 1 tablespoon maple. Serve the french toast warm, topped with whipped cream, berries, and maple Enjoy!
