Make the filling: In a large bowl, combine cream cheese and powdered sugar, and whisk well until combined and completely smooth (if grainy, beat with an electric mixer until smooth). Add melted white chocolate gently and gradually, until combined. Mix in vanilla extract. Using an electric mixer fitted with the whisk attachment, whisk heavy cream until soft peaks form. Avoid overbeating. Using a spatula, gently fold half of the whipped cream into the cream cheese mixture, then fold in the other half.

Make the topping: Warm the jam in the microwave, then strain the mixture through a fine mesh strainer to remove the seeds. Mix with the fresh strawberries.

Assembly: Divide ladyfinger pieces evenly between individual serving dishes. Evenly spoon (or pipe using a piping bag) about ½ cup of filling into each serving dish. Top with the strawberries. Cover and place in the fridge for at least one hour before serving, or up to 2 days.
