Mix cream cheese, guava paste, powdered sugar, and vanilla in a bowl until smooth.

Spread about 2 tablespoons of the mixture evenly over each tortilla.

Roll each tortilla tightly from one edge to the other.

Wrap in plastic and chill 20 minutes so slices hold shape.

Slice rolls into 1-inch pinwheels and arrange on a plate.

Brush with melted butter if you want a slight shine before serving.
