Cinnamon Roll Bundt Cake

INGREDIENTS

FOR THE CAKE
Butter, for pan
Flour, for pan
vanilla cake mix (including required ingredients)
1/2 tsp. cinnamon
1/2 c. cinnamon sugar
FOR THE GLAZE
4 oz. cream cheese, softened
2 c. powdered sugar
1/4 c. milk
Pinch kosher salt
DIRECTIONS

Make cake: Preheat oven to 350° and grease a bundt pan with butter then sprinkle with flour. Prepare cake mix according to package instructions then stir in cinnamon.
Pour ⅓ of the batter into the greased bundt pan. Sprinkle with about a full layer of cinnamon-sugar. Pour another ⅓ of the batter then top with another layer of cinnamon-sugar. Pour the remaining batter on top, then very gently, drag a butter knife through the batter to create swirls.
Bake until a toothpick inserted into the center of the cake comes out clean, about 30 minutes. Let cool for 10 minutes in pan then invert onto a cooling rack to cool completely.
Make glaze: In a large liquid measuring cup (or a medium bowl), whisk together cream cheese, powdered sugar, milk and salt. Drizzle over the cooled cake.
Let set for 10 minutes, then slice and serve.
