In a mixing bowl, combine the softened cream cheese, powdered sugar, and vanilla extract. Use a whisk to blend until smooth. Gently fold in the fresh raspberries.
Take four slices of bread and spread a generous amount of the cheesecake mixture on top of each slice. Place the remaining slices on top to create sandwiches.
In another bowl, whisk together the eggs, milk, and cinnamon until well combined.
Heat a frying pan or griddle over medium heat and add a tablespoon of butter, allowing it to melt and coat the pan.
Dip each sandwich into the egg mixture, ensuring all sides are coated. Allow excess egg mixture to drip off.
Place the coated sandwiches on the frying pan and cook for about 3-4 minutes on each side, or until golden brown and cooked through.
Repeat the process with the remaining sandwiches, adding more butter to the pan as needed.
Serve immediately, drizzled with maple syrup and topped with extra raspberries if desired.
