Instructions

Preheat the oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line it with parchment paper.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
Cream softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
Beat in eggs one at a time, followed by vanilla extract.
Gradually add dry ingredients to the butter mixture, alternating with sour cream. Mix until just combined.
Prepare the streusel: mix brown sugar, flour, and cinnamon, then stir in melted butter and nuts (if using) until crumbly.
Spread half the cake batter into the prepared pan. Sprinkle with half the streusel. Repeat with remaining batter and streusel.
Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Cool in the pan on a wire rack. If desired, drizzle with glaze before serving.

Notes

Substitute plain Greek yogurt for sour cream if needed.

To prevent streusel from sinking, ensure batter is thick and evenly layered.

Add a pinch of nutmeg or cardamom to enhance flavors.
