This moist and fluffy coffee cake is studded with tender cinnamon-spiced apples, brimming with buttery streusel, and generously drizzled in vanilla icing!
Preheat oven to 350ºF, and line a 9-inch round cake pan* with parchment paper. Spray with nonstick cooking spray.
Make the Spiced Apples:
In a medium saucepan over medium heat, cook the apples, water, brown sugar, butter and spices together until apples have softened, about 5-10 minutes. Remove from stove and set aside to cool slightly.
Make the Streusel:
Place the butter, flour, brown sugar, cinnamon, and salt in a medium bowl, and stir with a fork until it resembles clumps of sand. Don't add the pecans yet. Set streusel aside.
Make the Cake:
In a large bowl, whisk the flour, baking powder, salt, and sugar together until combined. Add the sour cream, milk, eggs, and vanilla, mixing until batter is almost combined. Pour in the melted butter and continue mixing until smooth. Gently fold in the spiced apples.
Spread half of the batter into the prepared pan. Sprinkle half of the streusel evenly over the batter. Pour the remaining batter on top, smoothing it out evenly. Toss the chopped pecans into the remaining streusel, then sprinkle evenly over batter.
Bake in the oven for 45-50 minutes, or until a toothpick inserted in several areas comes out clean. Allow to cool slightly while you make the icing.
Make the Icing:
In a medium bowl, whisk the powdered sugar, 3 Tablespoons heavy cream, and vanilla together until smooth. Add more heavy cream, if needed. Drizzle icing over coffeecake. Slice, serve, and enjoy!
