Preheat your oven to 375°F (190°C) and grease an 8-inch square baking dish with cooking spray.

In a small bowl, mix 1/4 cup brown sugar, 2 tablespoons butter, and corn syrup until smooth. Spread this mixture in the bottom of the prepared baking dish. Sprinkle with 1/2 cup pecans.

Unroll the crescent dough and press the seams together to form a large rectangle. Brush with the remaining 1 tablespoon of butter. Sprinkle with the remaining 1/4 cup brown sugar, cinnamon, and the remaining 1/4 cup pecans.

Roll up the dough jelly-roll style, starting at a wide end. Use a sharp knife to cut it into 9 equal slices. Place each slice cut-side down in the baking dish.

Bake for 18 to 20 minutes until puffed and golden. Remove from the oven and immediately invert onto a serving platter. Be cautious as the melted sugar is very hot. Allow it to cool slightly before serving warm.
