Add the eggs one at a time mixing well in between then add the rest of the Cake Batter ingredients and mix to combine then set aside.
In a small bowl mix together all ingredients of the Cinnamon Batter then set aside.
Pour half of the Cake Batter mixture in the bundt pan, then pour the Cinnamon Batter mixture over it, then finally cover that with the remaining half of the Cake Batter.
Bake for 35-40 mins or until a toothpick comes out clean, then cool for about 10 mins before removing from the pan.
In a mixing bowl, beat together the cream cheese, butter, and vanilla, until it's smooth and creamy, then start adding the powdered sugar until you have a consistency that you like (you can add a little milk to thin the icing out if it gets too thick).
Pour the icing over the de-panned cake and serve.
