This is my honey bun cake recipe.  It is really easy but oh so delicious.   1 box yellow cake mix, 4 eggs, 3/4 cup oil, 8 oz.sour cream (or sour cream substitute).  Mix ingredients, spread 1/2 mixture in a greased 9X13 cake pan.  Sprinkle 1/2 of the following mixture on top–1 cup brown sugar, 1 tbsp cinnamon.  Spread remainder of cake batter on top sprinkle remaining brown sugar mixture on top of this.  Swirl batter with a butter knife.  Bake at 350 degrees 35 minutes or until done.  For the glaze I use 2 cups powdered sugar, 2 tsp. vanilla and 5-6 tbsp evaporated milk.    Drizzle glaze on while cake is still warm and enjoy.  I would like to take a minute to thank my friend Marie for this recipe.  She is one of the best cooks I have ever known.  Unfortunately, Alzheimers has robbed her memory of many great recipes but every time I make this cake I think of her.  I hope you all enjoy it as much as we do.  God Bless.
