Classic Cinnamon Streusel Coffee Cake


For the Cake:

  • 2 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsalted butter, softened
  • 1 1/2 cups granulated sugar
  • 3 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup sour cream, room temperature

For the Streusel Topping:

  • 1 cup packed light brown sugar
  • 1 cup all-purpose flour
  • 1 tablespoon ground cinnamon
  • 1/2 cup unsalted butter, melted
  • 1 cup chopped nuts (walnuts or pecans), optional

For the Glaze:

  • 1 cup powdered sugar
  • 2 tablespoons milk
  • 1/2 teaspoon vanilla extract


  • 9×13 inch baking pan
  • Parchment paper
  • Mixing bowls
  • Electric mixer
  • Small saucepan
  • Whisk
  • Cooling rack

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan and line it with parchment paper for easy removal.

Step 2: Make the Streusel Topping

In a medium bowl, combine the brown sugar, flour, and cinnamon for the streusel topping. Add the melted butter and stir until the mixture resembles coarse crumbs. If you like, mix in chopped nuts for an extra crunch.

Step 3: Prepare the Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

Step 4: Cream the Butter and Sugar

In a large bowl, using an electric mixer, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes.

Step 5: Add Eggs and Vanilla

Add the eggs one at a time, beating well after each addition. Then, mix in the vanilla extract until well combined.

Step 6: Incorporate Dry Ingredients

With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, alternating with the sour cream. Begin and end with the dry ingredients, and mix until just combined.

Step 7: Layer the Batter and Streusel

Spread half of the batter into the prepared baking pan. Sprinkle half of the streusel mixture evenly over the batter. Repeat with the remaining batter and streusel.

Step 8: Swirl the Layers

Use a knife or a spatula to gently swirl the batter and streusel layers together. This creates a beautiful marbled effect.

Step 9: Bake

Bake in the preheated oven for 45-50 minutes or until a toothpick inserted into the center comes out clean. The streusel on top should be golden brown.

Step 10: Make the Glaze

While the cake is baking, prepare the glaze. In a small saucepan, heat the powdered sugar, milk, and vanilla extract over low heat, stirring until smooth. Set aside to cool slightly.

Step 11: Cool and Glaze

Allow the coffee cake to cool in the pan for about 15 minutes, then transfer it to a cooling rack. Drizzle the glaze over the warm cake, allowing it to set before slicing.

Step 12: Serve and Enjoy!

Slice into squares and serve your delicious homemade cinnamon streusel coffee cake. This moist and flavorful treat is perfect for breakfast, brunch, or any coffee-loving occasion.


  • Customize the streusel by adding a hint of nutmeg or substituting some flour with oats for texture.
