Spray counter lightly with non-stick cooking spray. Combine rolls and roll into a 14 inch circle. Place onto a sprayed 12 inch pizza pan. Poke with a fork several times to prevent bubbles from forming and bake at 350F 10 minutes.
Combine cream cheese, sugar vanilla and lemon juice and stir well. Add chocolate chips and mix well. Spread cream cheese mixture on baked cooled pizza crust, leaving 1/2 inch around edges uncovered.
For streusel, combine flour and sugars well. Add butter and vanilla. Mix with a fork until slightly lumpy and well combined. Sprinkle evenly over the cream cheese mixture. Sprinkle with chocolate chips. Bake for an additional 10 minutes or until crust is golden brown.
