Christine's Cinnabon Cinnamon Roll Cake

Growing up in Nebraska, my four children always had cinnamon rolls served with their chili at school.  All grown up, they still love the combination.  Christine made this for the Maman's 10th Annual Chili Cookoff and was delicious.  We brought some home and had for breakfast today!

3 cups flour
1/4 tsp. salt
1 cup sugar
4 tsp. baking powder
1 1/2 cup milk
2 eggs
2 tsp. vanilla
4 T. butter, melted
2 sticks (1 cup) butter, softened
1 cup brown sugar
2 T. flour
1 t. cinnamon

Glaze:
2 cups powdered sugar
5 T. milk
1 tsp. vanilla

Mix 3 cups flour, sugar, salt, baking powder, milk, eggs and vanilla.  Once combined well, slowly stir in 4 T. melted butter.  Pour batter into a greased 9 x 13 baking pan.

In a large bowl, mix the 2 sticks of softened butter, brown sugar, 2 tablespoons flour, cinnamon until well combined.  Drop evenly over the cake batter by the tablespoon and use a knife to marble/swirl through the cake.  Bake at 350 degrees for 25-30 minutes or until a toothpick comes out nearly clean from center.  

Place powdered sugar, milk and vanilla in a large bowl.  Whisk until smooth.  Drizzle over warm cake.  Serve warm or at room temperature.
