Instructions
- Heat oven to 350°F (175°C). Grease and line an 8×8-inch pan.

- Cake batter:
Cream butter and sugar until fluffy. Beat in eggs and vanilla.
Mix in sour cream.
Fold in flour, baking powder, baking soda, and salt just until combined. - Assemble:
Spread batter evenly in pan.
Sprinkle crumb topping generously—yes, it’s thick on purpose. - Bake for 40–45 minutes, until a toothpick comes out clean (crumbs are okay).
- Cool slightly, then dust with powdered sugar if you’re feeling fancy.
🔥 Optional upgrades
- Add a cinnamon swirl inside the cake
- Swap in cardamom or nutmeg for warmth
- Toss chopped walnuts or pecans into the crumbs
