Line a large sheet pan with parchment paper.
Frozen Bread Dough: Thaw the bread loaves in the refrigerator overnight. The dough should be thawed but still cold. (If using dinner rolls, dough may be thawed for 20-30 minutes on counter.)
Use a pizza cutter to cut the loaves into 8 strips each. For larger bread sticks, cut each loaf into 6 pieces. Dinner rolls - no need to cut.
Roll each dough strip into a 6 inch rope. For smaller bread sticks, cut each rope in half. (If using dinner rolls, roll each into 4" ropes.)
Cinnamon Sugar: In a shallow bowl whisk together the brown sugar, granulated sugar, cinnamon and allspice until combined.
Dip each piece of dough into the melted butter then roll in the cinnamon sugar.
Place side by side on the parchment lined baking sheet. Shape the ends of the bread sticks so they are uniform in size and will bake evenly.
Let Rise: Lay a piece of plastic wrap on top and allow to rise in a draft free place for around 1 1/2-2 hours or until doubled in size.
Bake: Preheat the oven to 350°F. Bake for 25 minutes until golden.
Rest on the pan for 5 minutes before glazing.
Cream Cheese Glaze: In a medium bowl, use a hand mixer to whip together powdered sugar, cream cheese, heavy cream and vanilla. After combining, warm gently in the microwave for a few seconds to make it pourable.
Drizzle over the bread sticks then serve the remainder on the side for dipping.
Pull apart and enjoy! (Yield: 16 medium or 32 small breadsticks and approximately 1 cup cream cheese dip.)
