1. Preheat the oven to 375°. Spread frosting in a greased 9"-square pan. Sprinkle pecans over frosting. Flatten each biscuit to about 1/4"-thickness. Place a chocolate kiss in center of each biscuit. Fold biscuits in half; press edges together to seal. Arrange over pecans, flat side down.
2. Bake on lowest position of oven rack at 375° for 25 minutes or until browned. Cool in pan on a wire rack 5 minutes. Invert onto a serving plate. Serve warm.
Be sure to set the oven rack in the lowest position possible to make sure the centers of the buns get done.
