# Expert Advice:

01 -
  • The cake is tender and moist without being heavy, and the lemon flavor is bold but never harsh.
  • You can have fresh, homemade cake on the table in just over an hour, which feels like magic on a weekday.
  • The crumble topping adds this perfect textural contrast that keeps you reaching for another slice.
02 -
  • Cold butter for the crumble is essential—if it's too soft, you'll end up with a cake topping instead of a proper crumble.
  • Don't skip the 10-minute cool in the pan; it helps the cake set so it won't break apart when you turn it out.
  • Fresh lemon juice makes a real difference here; bottled just doesn't have the same brightness.
03 -
  • Room temperature eggs and softened butter make a real difference in how evenly the batter mixes and how tender the final cake becomes.
  • If your crumble topping ever spreads or sinks during baking, you can brush it off after cooling and replace it with fresh crumble for a showstopper presentation.
