# Tips from hearthlykitchen:

01 -
  • They taste like a bakery treat but come together in one bowl with zero fancy techniques
  • The tart blueberries cut through all that buttery sweetness perfectly, so every bite feels balanced instead of just sugar overload
02 -
  • Overmixing the batter makes tough blondies so stop as soon as the flour disappears
  • Frozen blueberries work fine but add an extra minute or two to the baking time
  • The toothpick should have moist crumbs not raw batter when they're done
03 -
  • Room temperature ingredients mix more evenly so take the egg out early
  • Line your pan with parchment paper overhanging the sides like handles for easy removal
