    Due to the appealing photograph displayed in Anna’s cookbook for this streusel coffee cake, I have wanted to try this recipe for the longest time. Fortunately I did not long ago and was very pleased with the result. Be warned, this cake does not contain coffee, but its name rather refers to the fact that it is a prime candidate to go along with a coffee enjoyed at any time of the day. This cake is moist and flavourful without being overwhelmingly so. It is the perfect late-night snack to go along with any warm drink. Enjoy! 

Ingredients for topping:

  • 3/4 cup all-purpose flour
  • 1/2 cup light brown sugar, packed
  • 1/2 teaspoon ground cinnamon
  • Pinch of salt
  • 1/4 cup unsalted butter, melted

Ingredients for cake:

  • 1/2 cup unsalted butter, at room temperature
  • 3/4 cup sugar
  • 1 egg
  • 1 egg yolk
  • 1/2 cup sour cream
  • 1 teaspoon vanilla extract
  • 1  1/3 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt


  1. Preheat the oven to 350°F. Grease an 8-inch square pan and line the bottom and sides with parchment paper.
  2. For the streusel topping, stir together the flour, brown sugar, cinnamon and salt in a small bowl with a fork. Add the melted butter and stir well until the mixture is evenly moistened.
  3. For the cake, using a hand or stand mixer beat together the butter and sugar until the mixture is light and fluffy.
  4. Add the whole egg and the egg yolk. Beat well after each addition.
  5. Stir in the sour cream and vanilla extract.
  6. In a separate bowl, sift together the flour, baking powder, baking soda and salt. Whisk to combine.
  7. Add the flour mixture to the butter mixture and stir until just blended.
  8. Spread the batter into the prepared pan and sprinkle the streusel topping overtop. Bake the cake for about 35 minutes, until a toothpick inserted in the middle comes out clean.
  9. Cut into squares when the cake is cooled completely and enjoy!
