Tips & Tricks (5)

  • Blueberry Suspension Technique 🫐
    Toss fresh blueberries in a tablespoon of flour before folding into the batter to prevent them from sinking to the bottom of the bars.
  • Streusel Texture Secret 🥄
    Use cold butter and work it into the streusel topping with your fingertips to create a crumbly, crisp texture that doesn't become dense when baking.
  • Moisture Magic 💧
    For extra moist bars, substitute half the vegetable oil with Greek yogurt to add richness and prevent dryness while maintaining a tender crumb.
  • Freezer Preservation Hack ❄️
    If using frozen blueberries, do not thaw them before adding to the batter - mix them in frozen to prevent color bleeding and maintain their shape.
  • Golden Brown Perfection 🌟
    For an even, golden-brown streusel topping, place the bars on the upper-middle rack of the oven and rotate halfway through baking to ensure uniform coloration.
