Cinnamon Streusel Apple Coffee Cake

Ingredients

Coffee Cake

  • 3/4 cup unsalted butter at room temperature
  • 2 cups white sugar
  • 2 eggs beaten
  • 2 cups unbleached all-purpose flour
  • 1 tablespoon baking powder
  • 1/4 teaspoon salt
  • 1 1/4 cups sour cream
  • 1 tablespoon vanilla extract
  • 3 cups peeled diced apples

Cinnamon Filling

  • 1/2 cup brown sugar
  • 2 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon unsweetened cocoa powder

Streusel Topping

  • 3/4 cup white sugar
  • 1/4 teaspoon salt
  • 3/4 cup all purpose flour
  • 1 1/2 teaspoons ground cinnamon
  • 5 tablespoons butter melted
  • Optional: 1/2 cup chopped pecans

Instructions

  • Preheat oven to 350°.
  • Lightly grease and flour 10" tube pan. (I used a two piece tube pan and it's so helpful in releasing this cake.) You want an extra large tube pan as this is a big recipe!

Cinnamon Filling

  • In small bowl combine 1/2 cup brown sugar, 2 1/2 teaspoons ground cinnamon and 1/2 teaspoon unsweetened cocoa powder.
  • Set aside.

Streusel Topping

  • In small bowl combine 3/4 cup sugar, 1/4 teaspoon salt, 3/4 cup all purpose flour and 1 1/2 teaspoons cinnamon.
  • Stir in melted butter. Set aside.

Coffee Cake

  • Cream 3/4 cup butter and white sugar together in mixing bowl.
  • Stir in eggs, blending well, then add sour cream and vanilla extract.
  • Separately in small bowl, stir together flour, baking powder and salt.
  • Add flour mixture to wet ingredients until just combined.
  • Stir in apples.
  • Place half batter in prepared pan.
  • Sprinkle with cinnamon filling.
  • Pour remaining batter on top.
  • Sprinkle cinnamon streusel topping on top.
  • Bake for 60 - 75 minutes or until cake tester comes out clean. (Your cake may need even longer depending on the moisture content of the apples.)
  • Cool.
  • Loosen all accessible edges with sharp knife.
  • Carefully lift out of cake pan and place on cake platter.
  • (I used two hard metal spatulas underneath the bottom of the cake to lift it out of the the pan. )
