# Expert Advice:

01 -
  • The combination of tart lemon and sweet blueberries creates this perfect balance that keeps you coming back for just one more slice
  • That buttery crumble on top transforms an already delicious cake into something that feels like it came from a fancy bakery
02 -
  • I learned the hard way that room temperature ingredients make a huge difference, so take your butter and eggs out at least an hour before you start baking
  • Overmixing the batter once you add the flour will make your cake tough and dense, so fold gently and stop as soon as the flour disappears
03 -
  • Don't skip refrigerating the crumble while you make the batter, cold butter creates those perfect crispy nuggets we all love
  • If your blueberries are frozen, add them straight from the freezer to prevent them from turning the batter purple
