Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper.
Trim crusts off bread slices and flatten each slice with a rolling pin.
In a bowl, mix cream cheese, powdered sweetener, and vanilla until smooth.
Spread a thin layer of the mixture over each bread slice and roll tightly.
Combine granulated sweetener and cinnamon in a shallow dish.
Brush each roll with melted butter, then roll in the cinnamon-sweetener mix.
Place on baking sheet and bake for 12-15 minutes, or until golden and crispy.
Let cool slightly and serve warm.
