Ingredients

Scale
  • 2 cups (250 g) all-purpose flour
  • 2 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • ½ cup (115 g) unsalted butter, softened
  • 1 cup (200 g) granulated sugar
  • ¼ cup (50 g) packed brown sugar
  • 2 large eggs, room temperature
  • 1 tsp pure vanilla extract
  • ½ cup (120 ml) plain Greek yogurt (can substitute with sour cream)
  • ½ cup (120 ml) whole milk
  • 1 cup (120 g) chopped walnuts
  • ¼ cup (55 g) unsalted butter, melted and browned
  • ½ cup (100 g) packed brown sugar (for streusel)
  • ½ cup (60 g) all-purpose flour (for streusel)
  • 1 tsp ground cinnamon
  • ½ cup (60 g) chopped walnuts (for streusel)
  • 1 cup (120 g) powdered sugar
  • 1 tsp instant espresso powder
  • 2–3 tbsp (30–45 ml) whole milk (for glaze)
  • ½ tsp pure vanilla extract (for glaze)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9-inch cake pan or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter with granulated sugar and brown sugar on medium speed until light and fluffy, about 3 minutes.
  4. Beat in eggs one at a time, then mix in vanilla extract.
  5. Alternately add dry ingredients and Greek yogurt and milk to the batter, starting and ending with dry ingredients. Mix gently after each addition until just combined.
  6. Fold in chopped walnuts gently with a rubber spatula.
  7. To prepare streusel, melt butter in a small saucepan over medium heat until golden brown and nutty. Pour into a bowl and stir in brown sugar, flour, cinnamon, and chopped walnuts until crumbly.
  8. Pour batter into prepared pan and spread evenly. Sprinkle streusel topping evenly over the batter.
  9. Bake for 40-45 minutes or until a toothpick inserted near the center comes out clean or with a few moist crumbs and streusel is golden and crisp.
  10. Cool cake in pan on a wire rack for about 20 minutes.
  11. For the glaze, sift powdered sugar and espresso powder into a small bowl. Add 2 tablespoons milk and vanilla extract, whisk until smooth. Add more milk if needed for pourable consistency.
  12. Drizzle espresso glaze over warm cake and let set for at least 15 minutes before slicing.
  13. Serve warm or at room temperature with coffee or tea.

Notes

Use room temperature eggs and butter for best texture. Brown the butter carefully for the streusel to avoid bitterness. Do not overmix the batter to keep the cake tender. Cool cake before glazing to prevent glaze from melting off. Tent cake with foil if streusel browns too quickly.
