Preheat the oven to 350 degrees F. Spray a 10-cup bundt pan with nonstick cooking spray (I prefer the kind with flour in it - works like a charm!)
In a large bowl, add 1 box yellow cake mix, 3.4 ounce box instant vanilla pudding mix, 1 cup milk, 3 large eggs and ½ cup vegetable oil and stir until combined well.
Pour cake batter into the prepared bundt pan.
In a separate mixing bowl, combine ½ cup light brown sugar, ⅓ cup all purpose flour, ⅓ cup unsalted butter, melted and 1 Tablespoon ground cinnamon and mix well.
Drop small spoonfuls of the mixture onto the cake batter in the bundt pan and use a knife to swirl the cinnamon swirl mix into the cake.
Bake for about 40-45 minutes, or until a toothpick inserted comes out clean (the cake should also bounce back to the touch.)
Allow the cake to cool in the pan for 15 minutes before removing from the bundt pan and transferring to a wire rack to cool completely.
Meanwhile, prepare the cream cheese frosting. With an electric or stand mixer, beat together 8 ounce block cream cheese, softened to room temperature and ⅓ cup unsalted butter, softened to room temperature until smooth. Add 2 cups powdered sugar in increments (so it doesn’t fly everywhere) and continue to mix until well combined.
Mix in 1 teaspoon vanilla extract and 1 teaspoon ground cinnamon.
Once the cake is fully cooled, spread the frosting across the cake with a spatula, or transfer the frosting to a piping bag (or ziploc bag with the tip cut off).
Pipe on the frosting or spread it on the cake. Slice and serve!
