Grease a 9x13-inch pan with cooking spray. Spread 1 tbsp softened butter on the base of the pan. (I like to put a small plastic bag on my hand like a mitt and spread). Preheat oven to 350°F. Bring butter to room temp (see note 2).
In a medium bowl, combine 8 tbsp butter (that’s 1 stick), brown sugar, cinnamon, and salt. Beat with a hand mixer until you have a thick and smooth mixture.
Slice the entire slab of rolls horizontally, keeping individual rolls connected. Place the bottom half in the prepared pan. Spread just under half the butter mixture evenly over it. Place the top half of the rolls on and spread the remaining butter mixture on the top and sides. (Cover all parts of rolls except the bottom.)
Bake for 11–13 minutes or until the rolls are lightly golden on top. Prepare the glaze while baking.
Cream Cheese Glaze
Beat the cream cheese and butter with a hand or stand mixer until smooth. Add powdered sugar, vanilla, milk, and salt; mix until smooth. Continue to beat until the frosting is light and fluffy.
After removing the rolls from the oven, let them cool for a minute. Then spoon the frosting over them, ensuring it fills all crevices. Optionally apply a second layer of frosting once they cool a bit more. Enjoy!

Notes
Note 1: Use brick-style, full-fat cream cheese. Soften (unwrapped) in the microwave to avoid lumps in the glaze.Note 2: Let the butter sit at room temperature for about an hour or microwave it in short bursts. To microwave, heat for 5 seconds, flip, another 5 seconds, flip again, and then a final 5 seconds if needed. Be careful not to melt it at all.Storage: These are best fresh, but for leftovers, cool fully, then store in an airtight container in the fridge for up to a week.
