Preheat oven to 375 degrees F and prepare a cookie sheet by lining with parchment paper.
Open crescent roll dough and spread evenly into a parchment paper lined cookie sheet. Press dough together at seams to make a cohesive crust and roll excess dough over itself at the edges to form a crust.
Use a fork to pierce holes evenly over the crust then transfer to 375F and bake for 15 minutes or until golden brown. Allow crust to cool completely before covering with toppings.
While your dough cooks and cools, combine the softened cream cheese, sour cream, dill weed, and garlic powder in a large bowl. Stir well until completely combined.
Once pizza crust has cooled, spread cream cheese mixture evenly over the surface.
