A simple recipe for a buttery, moist coffee cake featuring a thick, cinnamon-brown sugar crumb topping, perfect for breakfast or brunch.

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

Instructions

  1. Preheat your oven to 350 degrees F. Grease and flour a 9×13 inch baking pan or a 10-inch tube pan.
  2. Prepare the streusel: In a medium bowl, whisk together the streusel flour, brown sugar, and cinnamon. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Set aside.
  3. Prepare the cake batter: In a separate bowl, whisk together the 1 3/4 cups flour, baking powder, baking soda, and salt. Set aside.
  4. In a large bowl, cream the softened butter and granulated sugar together until light and fluffy. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with the sour cream, beginning and ending with the dry ingredients. Mix until just combined; do not overmix.
  6. Pour half of the batter into the prepared pan. Sprinkle half of the streusel mixture evenly over the batter. Gently spoon the remaining batter over the streusel layer. Top with the remaining streusel mixture.
  7. Bake for 45 to 55 minutes, or until a wooden pick inserted into the center comes out clean.
  8. Let the cake cool in the pan on a wire rack for at least 20 minutes before slicing and serving.

Notes

  • For an extra layer of flavor, gently swirl a knife through the batter before adding the final streusel layer to create a cinnamon swirl effect.
  • If you prefer a thinner glaze, mix 1 cup powdered sugar with 2-3 tablespoons of milk or lemon juice and drizzle over the cooled cake.
  • You can use a 9-inch square pan, but reduce the baking time slightly.
