A simple recipe for a buttery, moist coffee cake featuring a thick layer of cinnamon streusel 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
  • 1 tablespoon ground cinnamon
  • 1/2 cup (1 stick) cold unsalted butter, cut into small pieces

Instructions

  1. Preheat your oven to 350 degrees F (175 degrees C). Grease and flour a 9×13 inch baking pan.
  2. In a medium bowl, whisk together the 1 3/4 cups flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, cream the softened butter and granulated sugar together until light and fluffy. Beat in the eggs one at a time, then mix in the vanilla extract.
  4. Alternate adding the dry ingredients mixture and the sour cream to the wet ingredients, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix.
  5. Prepare the streusel: In a separate bowl, combine the 1 cup flour, brown sugar, and cinnamon. Cut in the 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 all of the streusel topping evenly over the batter. Gently spoon the remaining batter over the streusel layer.
  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 before slicing and serving.

Notes

  • For an extra layer of flavor, mix 1 teaspoon of cinnamon into the cake batter before adding the flour mixture.
  • If you prefer a glaze, whisk 1 cup powdered sugar with 2-3 tablespoons of milk until smooth, then drizzle over the cooled cake.
  • You can use a 9-inch tube pan instead of a 9×13 pan; reduce baking time slightly and check for doneness sooner.
