In a bowl, mix cream cheese, powdered sugar, and vanilla extract until smooth.

Gently fold in the diced strawberries.

Flatten each slice of bread slightly with a rolling pin. Spread a spoonful of the cheesecake mixture on 4 slices, then top each with another slice to make sandwiches. Press edges gently to seal.

In a shallow bowl, whisk together the eggs, milk, and cinnamon.

Dip each sandwich in the egg mixture, coating both sides. If using, press each side into graham cracker crumbs for extra texture.

Heat a skillet over medium heat and add butter or oil. Fry sandwiches for about 2-3 minutes per side, until golden brown.

Remove from skillet and place on a paper towel-lined plate. Dust with powdered sugar before serving.
