Hi Kathy,
Thanks for asking for my recipe...I have made literally thousands of these...a very popular item.
CINNAMON POUNDCAKE
l box any yellow cake mix with pudding in the mix
1 small box vanilla instant pudding
1/2 c. vegetable oil
l cup buttermilk
2 tsp. imitation butter flavoring
1 tsp. vanilla flavoring
4 large eggs
Cinnamon sugar
Mix all above JUST until blended..the batter is very thick..
Grease and flour a tube pan or 10 mini-loaf pans
spoon in half the batter and sprinkle cinnamon sugar (about 3-4 level tbsp)
spoon on rest of batter
Bake at 350 degrees about 40 minutes, do not overbake..and it's okay to take it out of the oven when it's still a little moist on top, as it will continue to cook from it's own heat when taken out of oven (moister cakes!)
The icing:
l cup powdered sugar
2 tsp. milk
2 tsp. light corn syrup
1 tsp. vanilla
This icing will dry to a shiny hard finish, and is great to use with cookies too..the flavor possibilities are endless...
P.S. This cake tastes better the next day...
