Heat oven to 325 degrees. Follow package directions for "crisping" Phyllo cups. When done, set aside to cool. Remove caps from strawberries and chop into small pieces.
Using a hand or stand mixer, whip cream cheese and sour cream together until smooth. Add in lemon juice, zest, vanilla and mix. Carefully add the sugar and beat until mixture is smooth. Place cream cheese mixture in a piping or plasic ziptop bag. Cut off end and pip filling into each Phyllo cup. Top with chopped strawberries.
In a microwave safe bowl, melt chocolate chips for 30 seconds or until totally melted. Stir. Using a spoon, drizzle chocolate over each filled Phyllo cup. Serve immediately. Can be stored in refrigerator until ready to serve.
