How to Make It
Preheat oven to 375°. Bake pecans and butter in a lightly greased 8-inch round cake pan 2 minutes. Swirl pan to combine, and bake 2 more minutes. Remove from oven, and stir in brown sugar, corn syrup, and 1/2 tsp. cinnamon; spread mixture over bottom of pan.
Unroll crescent roll dough, and separate into 4 rectangles, pressing perforations to seal. Stir together granulated sugar and remaining 1/2 tsp. cinnamon; sprinkle over rectangles. Roll up each rectangle tightly, starting at 1 long side; press edges to seal. Cut each log into 5 slices; place slices, cut sides down, in prepared pan. (Space slices equally in pan; slices will not touch.)
Bake at 375° for 14 to 16 minutes or until center rolls are golden brown and done. Remove from oven, and immediately invert pan onto a serving plate. Spoon any topping in pan over rolls.
