Description

A recipe for a moist and tender sour cream coffee cake featuring a rich cinnamon streusel swirl and crumb topping, perfect for breakfast or dessert.


Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup granulated sugar, divided
  • 1/2 cup (1 stick) unsalted butter, softened
  • 2 large eggs
  • 1 cup full-fat sour cream
  • 1 teaspoon vanilla extract
  • For the Streusel: 1/2 cup all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 cup (1/2 stick) cold unsalted butter, cut into small pieces


Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. Grease and flour a 9-inch square baking pan or an 8-inch round cake pan.
  2. In a medium bowl, whisk together 1 3/4 cups flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, cream together 1/2 cup granulated sugar and 1/2 cup softened butter until light and fluffy. Beat in the eggs one at a time, mixing well after each addition. Stir in the sour cream and vanilla extract.
  4. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
  5. Prepare the streusel: In a separate small bowl, combine 1/2 cup flour, brown sugar, and cinnamon. Cut in the 1/4 cup cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  6. Spread half of the cake batter into the prepared pan. Sprinkle half of the streusel mixture evenly over the batter.
  7. Gently spread the remaining cake batter over the streusel layer. Sprinkle the remaining streusel mixture on top of the cake batter.
  8. Bake for 40 to 45 minutes, or until a wooden pick inserted into the center comes out clean.
  9. Let the cake cool in the pan on a wire rack for at least 20 minutes before slicing and serving.

Notes

  • For a richer flavor, you can substitute 1/4 cup of the flour in the cake batter with finely ground pecans.
  • If you prefer a glaze, whisk 1 cup powdered sugar with 2 tablespoons milk and 1/2 teaspoon vanilla extract, then drizzle over the cooled cake.
  • This cake freezes well; wrap cooled slices tightly in plastic wrap and foil.
