Sift 1 1/2 cups flour. You could skip the sifting, but it will improve the texture. See note.
Add 1/2 cup sugar, 1/4 teaspoon salt, two teaspoon baking powder. Mix dry ingredients.
Add one egg, 3/4 cup milk, and one teaspoon vanilla. Mix well.
Melt 1/4 cup butter in a microwave. Mix in well.
Prep a 9X6 baking dish with PAM and add batter.
Mix topping. 1/2 cup cold butter, 1/2 cup brown sugar, one tablespoon cinnamon, and one tablespoon flour. A pie cutter is good here. If you don't have that, dice the cold butter before starting and use a fork. Mix until crumbly.
Add the topping to the batter. Cut it into the batter with a knife. I moved the knife at 1-inch segments both directions several times.
Bake until toothpick comes out clean. About 30 minutes.
Mix glaze. One cup powder sugar, 1/2 teaspoon vanilla and two tablespoons milk.
Drizzle the glaze over the warm cake and evenly spread over the cake.
Pro Tips for Cinnamon Roll Cake
An easy recipe to double using a 9 X 13 standard cake pan. Cooking time will stay about the same.
Butter is a key component of this cake. Please use real butter.
Sifting flour will make your flour "lighter" and your final results lighter and less dense. I think it is quite noticeable in this recipe and will be doing it more. If you don't have a sifter then running the flour through a strainer will work. If you don't have that, then a whisk or fork can help. Or skip it.
Good at room temperature for severe days. Make the day ahead for the holidays.
