Ingredients

Scale

  • 1 large apple, peeled and diced
  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup brown sugar, packed
  • 1/2 cup unsalted butter, softened
  • 2 large eggs
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1/2 cup sour cream

    • 1/3 cup all-purpose flour
    • 1/4 cup unsalted butter, cold and cubed
    • 1 teaspoon ground cinnamon

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and flour a 9-inch square baking pan.
  2. In a medium bowl, mix the streusel topping ingredients: brown sugar, flour, cinnamon, and cold butter. Use a pastry cutter or fork to combine until crumbly. Set aside.
  3. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
  4. Add eggs one at a time, beating well after each addition, then stir in vanilla extract.
  5. In a separate bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
  6. Gradually add the dry ingredients to the wet mixture alternately with the sour cream, beginning and ending with the dry ingredients. Mix until just combined.
  7. Fold in the grated butternut squash, diced apple, and chopped pecans if using.
  8. Pour the batter into the prepared pan and spread evenly.
  9. Sprinkle the streusel topping evenly over the batter.
  10. Bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean.
  11. Allow the coffee cake to cool in the pan for 15 minutes before transferring to a wire rack to cool completely.
  12. Slice and serve warm or at room temperature.

Notes

For extra flavor, serve with a drizzle of caramel sauce or a dollop of whipped cream. This cake also freezes well for up to 2 months.
