Tunnel of Fudge Cake

I have been looking for a tunnel of fudge cake recipe like I had when I was younger, I have tried many recipes over the years and the center of the cake was never right. Than I came across this recipe in a Pillsbury calender, I changed it up to suite what I was looking for and I am very please with the results. The center is very similar to a fudge recipe I have been making for over twenty years. After the cake cools dust with powder sugar or if you are a chocolate lover like I am than drizzle the cake with the chocolate glaze.
