For bars. whisk flour, baking powder, baking soda, and salt together in a bowl.

Whisk together white sugar and oil in a large bowl until well combined. Whisk in milk, eggs, and vanilla extract.

Stir flour mixture into egg mixture until just combined.

Gently fold in blueberries.

Spread batter evenly into the prepared pan.

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.
