Tunnel of Fudge Bundt Cake

Another one to try.....this one is from scratch.....

Tunnel of Fudge Bundt Cake
1 3/4 c. butter, softened
1 c. sugar
1/2 c. brown sugar
2 1oz. squares unsweetened chocolate, melted and cooled
6 eggs
2 c. powdered sugar
2 1/4 c. flour
1/2 c. cocoa
2 c. chopped pecans
Combine butter, sugar and brown sugar, beat until mixture is light and fluffy. Add melted and cooled chocolate, beating until combined. Add eggs one at a time beating throughly after each addition until eggs combine with butter mixture (this can take some time). Gradually add powdered sugar, mixing well. Stir in flour, cocoa and pecans by hand or lowest speed on mixer until blended. Spray bundt pan and pour in batter. Bake at 350 for 50 to 60 minutes, until crust looks dry and shiny (this cake has soft fudge center so a toothpick test won't work). Cool cake in pan on rack for 1 hour. Invert onto serving platter. Cool completely. Sprinkle with powdered sugar.
