- 1/2 cup unsalted butter, softened
 
- 1 cup granulated sugar
 
- 2 large eggs
 
- 1 teaspoon vanilla extract
 
- 1 cup sour cream
 
- 1 3/4 cups all-purpose flour
 
- 1 teaspoon baking powder
 
- 1/2 teaspoon baking soda
 
- 1/4 teaspoon salt
 
- 1/2 cup brown sugar (for streusel)
 
- 1 tablespoon ground cinnamon (for streusel)
 
- 2 tablespoons all-purpose flour (for streusel)
 
- 2 tablespoons cold unsalted butter, cubed (for streusel)
 
- 1/2 cup powdered sugar (for glaze)
 
- 1–2 tablespoons milk (for glaze)
 
- 1/2 teaspoon vanilla extract (for glaze)
 
		 
	 
	
		
		
			
- Preheat oven to 350°F (175°C). Grease and flour an 8×8-inch or 9×9-inch baking dish.
 
- In a mixing bowl, cream together softened butter and granulated sugar until light and fluffy.
 
- Add eggs one at a time, beating well after each addition. Mix in vanilla extract and sour cream.
 
- In a separate bowl, whisk together flour, baking powder, baking soda, and salt. Gradually add dry ingredients to the wet ingredients and mix until just combined.
 
- In another bowl, prepare the streusel by mixing brown sugar, cinnamon, and flour. Cut in cold butter with a fork or pastry cutter until crumbly.
 
- Spread half the cake batter into the prepared pan. Sprinkle half the streusel over the batter.
 
- Add remaining batter on top and spread gently. Sprinkle with the remaining streusel.
 
- Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pan.
 
- For the glaze, whisk together powdered sugar, milk, and vanilla extract until smooth. Drizzle over the cooled cake before serving.
 
		 
	 
	
		Notes
