Nanna'S Old World Cinnamon Crumb Coffee Cake - cooking recipe

Ingredients

1 1/2 cups all-purpose flour
2 1/2 teaspoons baking powder
3/4 cup sugar
1/2 cup butter, melted
1/2 cup sour cream
1/2 teaspoon salt
1 egg
1/2 cup milk
1 teaspoon vanilla
1/2 cup brown sugar
2 tablespoons butter
2 tablespoons all-purpose flour
1 teaspoon cinnamon

Preparation

Batter: Sift 1 1/2 cups flour, baking powder, and salt together and set aside. In a separate bowl, beat egg until frothy. Beat in sugar and butter until combined. Add milk, sour cream, and vanilla. Add to flour mixture a little at a time and mix on low until combined. Do not over mix. If the batter is too stiff add a little more milk.
Streusel topping: Combine last 4 ingredients (make sure your butter for the streusel is chilled) in a small bowl and mix together, then set aside.
Put 1/2 the batter in a 8x8 - inch greased pan and spread evenly. Sprinkle 1/2 streusel over batter. Repeat. Bake at 350 degrees in a preheated oven for 25 to 30 minutes. Topping with chopped nuts is also an option if you like nuts!
