If you're looking for a moist and dense coffee cake that provides all the classic flavors of cinnamon rolls in a coffee cake form, this easy Cinnamon Roll Cake recipe is for you.
Pour the prepared cake batter into a greased 9-inch by 13-inch baking pan.
Prepare the Cinnamon Swirl
Prepare the cinnamon swirl in a medium mixing bowl, by combining the softened butter, brown sugar, flour, and cinnamon.
1 cup butter, 1 cup dark brown sugar, 2 tablespoon all-purpose flour, 1 tablespoon cinnamon
Dollop 12 spoonfuls of the prepared cinnamon swirl mixture evenly over the cake batter.
Using a butter knife, swirl the dollops of cinnamon swirl into the batter.
Bake the cake, uncovered, on the center oven rack for 35-40 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Prepare the Glaze
While the cake is baking, prepare the glaze in a medium mixing bowl. Place the powdered sugar, kosher salt, and vanilla in the bowl, adding the milk a little at a time until the glaze reaches the desired consistency, beating until smooth.
Let the cake cool for 30 minutes, then drizzle the prepared glaze over the top of the still warm cake, spreading it out evenly with a spatula.
Cake is easiest to serve if it is allowed to cool completely before slicing it into squares. If served warm, the cake is easiest to serve by scooping it from the pan with a large serving spoon.
Notes
Don't bake the cake solely by time. Use a toothpick or cake tester to be sure the cake is fully cooked at the center before removing from the oven. When a toothpick inserted into the very center of the cake comes out perfectly clean, the cake is done.If you opt to serve this cake warm, just know that it is crumbly and will totally fall apart. It's still quite delicious but the presentation kind of goes out the window when you serve it warm. Use a large serving spoon instead of trying to cut the warm cake with a knife.
