Preheat oven to 400 degrees. Line a baking sheet with parchment paper or a non stick baking mat.

In a small bowl, mix together cream cheese, 1/4 cup sugar, and vanilla until smooth.

Lay your puff pastry on the non stick mat. Roll out slightly with a rolling pin. Smooth together seams if necessary.

Use a pizza cutter to score a rectangle in the middle. Do not cut all the way through. Spread cream cheese mixture evenly across the rectangle.

Layer cream cheese with rows of strawberries and blueberries.

Using a pizza cutter, cut strips on a diagonal on both sides of the fruit. Fold pieces over one another. Once you get to the end, tuck ends up on top. Brush with beaten egg and sprinkle with remaining sugar. Put back in fridge for 10-15 minutes to rechill.

Remove from fridge and bake in the oven for 16-20 minutes, or until golden brown. Let cool on a wire rack. Serve room temperature.
