Cinnamon Roll Cake

 I saw this recipe on Pinterest, which lead me to HERE.  This cake was very good.  However, if I were to make it again, I would make a few changes, and I will list them below. 

Ingredients:
Cake:
3 cup flour
1/4 tsp salt
1 cup sugar
4 tsp baking powder
1 1/2 cup milk
2 eggs
2 tsp vanilla
1/2 c butter, melted

Topping:
1/2 cup butter (1 cube), softened to almost melted (I halved this from original recipe) 
1 cup brown sugar
2 Tbsp flour
1 Tbsp cinnamon
Glaze:
2 c. powdered sugar
5 Tbsp. milk
1 tsp. vanilla

Directions:
Mix everything together except for the butter. Slowly stir in the melted butter and pour into a greased 9x13 pan. For the topping, mix all the ingredients together until well combined. Drop by small teaspoons evenly over the batter and swirl in zig-zag pattern with a knife, horizontally, then vertically.  Bake at 350 for 28-32 minutes (this may take longer, make sure the center is firm before taking out).
While warm drizzle the glaze over the cake.
