Preheat the oven to 375 degrees. Prepare a large rimmed baking sheet with parchment paper spritzed with nonstick cooking spray.
Unroll 2 sheets of dough and place on the baking sheet, pinching the middle seam together. Place in the oven and bake for 8 to 10 minutes or until the crescent dough just begins to brown on the edges. Remove from the oven.
In a large mixing bowl, combine the cream cheese, seasoning packet, sour cream, and cheddar cheese. Stir in the chicken and bacon until well blended.
Spread the chicken mixture over the crescent dough leaving the edges clean.
Unroll the remaining crescent dough and place over the chicken mixture. Seal the edges by pinching.
Brush the top with melted butter and sprinkle with garlic powder.
Return to the oven and bake for 12 to 13 minutes or until the crescent dough is baked and golden.
Cut into squares and serve.
