Preheat the oven to 400 degrees F and line a baking sheet with a piece of parchment.
On a clean, flat surface unroll the crescent dough (gently sealing the cracks) with the longest side closest to you.
Spread the mustard lightly over the dough, leaving a 1/2-inch border around the sides.
In small mixing bowl, mix together the whipped cream cheese, shallot, and ½ cup of bacon. Spread over the dough. Sprinkle the remaining bacon over the cream cheese.
With the longest side closest to you, roll up the pastry and slice into 1/2-inch pieces. Place the pinwheels on the prepared baking sheet.
Melt the butter in a small microwavable bowl, and add the garlic powder, and parsley. Mix well, and brush each pinwheel.
Bake until golden brown, 12 to 15 minutes or as directed according to package. Serve warm.
