# Expert Advice:

01 -
  • The Greek yogurt keeps the cake impossibly moist without that heavy, dense feeling some sheet cakes have.
  • Fresh blueberries burst with flavor and look stunning dotted throughout, making it feel fancier than the minimal effort required.
  • The lemon icing is so simple you can drizzle it in five minutes flat, yet it tastes like you spent hours perfecting it.
02 -
  • Room temperature eggs and Greek yogurt aren't fussy requirements; they actually make the batter emulsify properly so the cake rises and stays tender.
  • The moment you see the blueberries in the batter, you're tempted to keep folding, but stop when you still see a few streaks of batter. Overmixing is the enemy of sheet cake texture.
03 -
  • When your lemon juice and zest are already in the batter, you don't need to oversaturate the icing, so start with just 1 tablespoon juice and taste before adding more.
  • If blueberries are expensive or out of season, frozen blueberries deliver better flavor than sad, tasteless fresh ones from halfway across the world.
