Crust

Preheat oven to 400 degrees

On a lightly floured surface roll puff pastry large enough to cut out into a 12” circle( I used a dinner plate as a template) 

Transfer to a pizza pan or baking sheet lined with parchment paper. Brush the entire surface of the circle with the egg wash. Pierce the circle with a fork to prevent the crust from puffing up to high. Gently fold over the edged of the circle to form a crust.

Bake crust for 10 minutes, then remove from oven and set aside while making the sauce.

In a medium bowl, place cream cheese, sugar, and vanilla. Using a hand mixer beat mixture until smooth.

Spread cream cheese “sauce” evenly over the parbaked crust.

Sprinkle chocolate chips evenly over top and press/spread into the “sauce.” 

Prepare the topping.

Topping

 Melt the butter and stir in the vanilla stirring to blend, and set aside.

Mix together flour and sugars. Add butter mixture and using a fork combine until mixture resembles coarse crumbles.

Sprinkle topping evenly over pizza

Bake pizza in 400F 10 minutes or until streusel turns a golden brown.

Remove from oven, allow to cool slightly.

 Slice and serve.
