In a small bowl, mix the softened cream cheese and powdered sugar until smooth and creamy. Spread the cream cheese mixture onto one side of four bread slices.
Add sliced strawberries and a spoonful of strawberry jam on top of the cream cheese layer. Cover with the remaining bread slices to form sandwiches.
In a shallow dish, whisk together the eggs and milk. Dip each sandwich into the egg mixture, ensuring both sides are evenly coated.
Heat a large skillet over medium heat and melt 1 tablespoon of butter. Place the sandwiches in the skillet and fry for 2-3 minutes on each side, or until golden brown.
Remove from the skillet and let drain on a paper towel-lined plate. Dust with powdered sugar before serving.
