Preheat the oven to 200°F.
Combine the ingredients for the french toast mixture (except butter) in a large shallow bowl.
Slice the croissants lengthwise, but be sure to not cut all the way through.
Spread a heaping amount of strawberry jam on one side of the croissants and the maple cream cheese on the other. Close the croissant.
Heat a large skillet over medium heat and coat with nonstick spray or butter.
Dip the croissant into the french toast mixture. Letting it soak on both sides for about 5-10 seconds each side (do not soak too long or the french toast will be soggy). Let excess liquid to drip back into the bowl.
Cook until golden brown on one side, about 2-4 minutes per side. Flip and continue to cook until golden brown on the second. Remove from the heat and transfer to prepared a parchment-lined baking sheet. Keep warm in the oven until serving time. Repeat with remaining stuffed croissants.
Serve with maple syrup, powdered sugar, whipped cream, and strawberries as desired.
