1 box yellow cake mix
5 eggs
1/2 cup oil
8 ounces sour cream
1/2 cup sugar
1 cup brown sugar
4 teaspoons cinnamon
1 cup raisins
6 tablespoons butter, melted
3/4 cup powdered sugar
Preheat oven to 300 degrees. With a mixer, combine cake mix, eggs, oil, sour cream and sugar. Mix until smooth.
In a separate bowl, combine brown sugar, cinnamon and raisins. Pour half of the batter into a well-greased 13-by-9-inch pan.
Sprinkle brown sugar mixture evenly over the first layer of batter. Top with the remaining batter and swirl with a knife. Bake for one hour or until a toothpick inserted in the center comes out clean.
While the cake is baking, prepare the glaze by combining melted butter and powdered sugar in a bowl. Set aside. When cake is done baking, remove it from the oven and spread glaze evenly over the top.
