For the Cake:
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan.
In a large mixing bowl, whisk together the flour, salt, sugar, and baking powder.
Add the milk, eggs, and vanilla extract to the dry ingredients. Mix until the batter is smooth.
Stir in the melted butter until well combined.
For the Cinnamon Filling:
In another bowl, mix together the softened butter, brown sugar, flour, and ground cinnamon until it forms a crumbly texture.
Assembly:
Spread half of the cake batter into the prepared baking pan.
Sprinkle the cinnamon filling evenly over the batter.
Dollop the remaining cake batter on top of the cinnamon filling. Use a knife to swirl the batter and filling together.
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
For the Cream Cheese Frosting:
While the cake is baking, prepare the cream cheese frosting. In a mixing bowl, beat the softened cream cheese and butter together until smooth.
Add the powdered sugar and vanilla extract. Mix until well combined. Add milk as needed to reach your desired frosting consistency.
Once the cake is done, remove it from the oven and let it cool slightly.
Spread the cream cheese frosting over the warm cake. It will melt slightly and create a delicious glaze.
Slice and serve your Cinnabon Cinnamon Roll Cake while it’s still warm for the best flavor.
