Here's how I did it:
- 3 cups Flour
- 1/4 teaspoon Salt
- 1 cup Sugar
- 4 teaspoons Baking Powder
- 1 1/2 cups Milk
- 2 Eggs
- 2 teaspoons Vanilla
- 1/2 cup ( 1 stick) Butter, melted
- 1 cup ( 2 sticks) Butter, softened
- 1 cup Brown Sugar
- 2 Tablespoons Flour
- 1 Tablespoon Cinnamon
- 2 cups Powdered Sugar
- 5 Tablespoons Milk
- 1 teaspoon Vanilla
Preheat oven to 350 degrees. Spray a 9×13 glass baking pan with cooking spray. Set aside.
In an electric or stand mixer add the flour, salt, sugar, baking powder, milk, eggs, and vanilla. Once combined well , slowly stir in the melted butter. Pour into the prepared 9×13 baking pan.
For topping, In a large bowl mix the 2 sticks of butter, brown sugar, flour and cinnamon together until well combined and creamy. Drop evenly over the batter by the tablespoonfuls and use a knife to marble/swirl through the cake.
Bake at 350 for 35-40 minutes or when a toothpick inserted near the center comes out nearly clean.
For Glaze: In a medium bowl, mix the powdered sugar, milk and vanilla together with a whisk. Drizzle evenly over the warm cake. Serve warm or at room temperature.
