In a mixing bowl, combine 8 ounces of softened cream cheese, 1/4 cup of powdered sugar, and 1 teaspoon of vanilla extract. Beat on medium speed for 2-3 minutes until smooth and creamy.

Take 4 slices of thick bread and spread the cream cheese filling on one side of each slice. Sandwich two slices together with the filling in the center.

In a large bowl, whisk together 4 large eggs, 1 cup of milk, and 1 teaspoon of ground cinnamon until fully blended and frothy, about 1-2 minutes.

Heat a non-stick skillet over medium heat and add 2 tablespoons of butter or oil. Heat for 2-3 minutes until bubbling.

Dip each sandwich briefly in the custard mixture, ensuring both sides are coated but not soaked. Cook for 2-3 minutes per side until golden brown.

Remove from the skillet and dust with powdered sugar. Serve immediately with optional toppings.
