For the cake, grease and flour a bundt pan and set aside. Preheat oven to 350 degree F.
In a mixing bowl, combine flour, sugar, baking powder, baking soda and salt. Beat in softened butter until mixture is crumbly. Add in eggs, vanilla, cinnamon and milk. Beat for 3-4 minutes until smooth and fluffy.
In a separate mixing bowl, combine brown sugar and cinnamon for the filling. Use a fork to blend evenly.
Pour half of the cake batter into the bundt pan. Sprinkle the cinnamon sugar mixture over the batter. Top with the remaining cake batter.
Bake for 55-60 minutes until browned. Allow to cool in pan about 10 minutes, then flip onto a cake plate and cool completely.
For the glaze, whisk together the powdered sugar, 2 Tbsp milk and cinnamon. Add more milk if needed to get desired consistency. Drizzle over cooled cake. Store covered at room temperature for 4-5 days. ENJOY.
Notes
My favorite part of this cake is the swirls of cinnamon filling inside! Here’s how to create a pretty swirl pattern with the cinnamon sugar.
Add half the batter to your bundt pan.
Sprinkle the cinnamon sugar all over the batter.
Pour the rest of your batter on top.
The cinnamon glaze is another element that sets this cake apart from the crowd. Ideally, the glaze should be thin enough to pour, but thick enough to set up on the cake without dripping off.
