Ingredients

Scale

Cake Batter

  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 Tablespoon melted butter
  • 1 egg (room temperature)
  • 1½ cups buttermilk (room temperature)

Streusel Filling

  • 3 Tablespoons softened butter
  • 1 Tablespoon cinnamon
  • ½ cup all-purpose flour
  • ½ cup brown sugar
  • (Optional) chopped nuts

Crumb Topping

  • ½ cup firmly packed light brown sugar
  • ½ cup all-purpose flour
  • ½ Tablespoon cinnamon
  • ¼ cup cold butter, cubed
  • ⅛ teaspoon salt

Drizzle Glaze

  • ½ cup powdered sugar
  • 2½ teaspoons milk (more if needed for drizzling)

Instructions

  1. Preheat Oven: Heat oven to 375 degrees F. Optionally, line a 9×9-inch baking dish with parchment paper or grease it well.
  2. Combine Dry Ingredients: In a large bowl, mix together 2 cups flour, baking powder, baking soda, and salt.
  3. Mix Wet Ingredients: In a medium bowl, whisk melted butter, egg, and buttermilk until smooth and well combined.
  4. Combine Batter: Add the wet ingredients to the dry ingredients and stir gently until just combined. Avoid overmixing.
  5. Layer Base Batter: Pour half of the batter into the prepared baking dish and spread evenly.
  6. Make Streusel Filling: In a small bowl, blend softened butter, cinnamon, ½ cup flour, and ½ cup brown sugar with a fork until crumbly. Add optional chopped nuts if desired.
  7. Add Streusel Layer: Sprinkle the streusel evenly over the batter in the dish.
  8. Add Remaining Batter: Spread the remaining cake batter carefully over the streusel layer.
  9. Prepare Crumb Topping: Cut cold butter into small cubes and place in a small bowl. Add light brown sugar, flour, cinnamon, and salt. Use a fork or pastry blender to combine until coarse crumbs form.
  10. Top the Cake: Sprinkle the crumb topping evenly over the top of the final batter layer.
  11. Bake: Place the baking dish in the oven and bake for 30 to 40 minutes, or until a toothpick inserted into the center comes out clean.
  12. Cool: Remove cake from oven and cool for 15 minutes on a cooling rack. Then lift the cake out from the pan using parchment paper (if used) and allow it to cool completely.
  13. Make Drizzle Glaze: In a small bowl, mix powdered sugar with 2 to 3 teaspoons of milk, adding more milk if necessary, to create a smooth drizzle glaze.
  14. Decorate: Drizzle the glaze over the cooled coffee cake before serving.

Notes

  • Use room temperature eggs and buttermilk to ensure better mixing and cake texture.
  • For extra flavor and texture, chopped nuts such as walnuts or pecans can be added to the streusel filling.
  • Be careful not to overmix the batter to keep the cake tender and light.
  • The glaze should be drizzled once the cake has completely cooled to prevent it from melting and running off.
  • Store leftover cake covered at room temperature for up to 3 days or refrigerate for up to a week.
