Step 1: Warm Up the Oven

Turn the oven to 350F (175C).

Get your mixing bowl ready for some delicious cookie bar magic.

Step 2: Create Creamy Base

Grab these ingredients:

Softened butter
Sugar

Whip the butter and sugar together until they become light and fluffy.

Toss in the egg, vanilla extract, lemon zest, and lemon juice.

Mix everything until smooth and dreamy.

Step 3: Build the Dry Foundation

In another bowl, sift together:

Flour
Baking powder
Salt

Slowly blend the dry ingredients into your creamy mixture.

Gently fold in fresh blueberries, being careful not to crush them.

Step 4: Spread and Bake

Pour the batter into a prepared baking pan.

Spread it evenly with a spatula.

Slide the pan into the preheated oven and bake for 12-15 minutes.

Look for golden edges and a set center.

Once done, remove and let cool completely on a wire rack.

Step 5: Add Decadent Drizzle

Melt white chocolate and heavy cream in a microwave-safe bowl.

Heat in short bursts, stirring until silky smooth.

Drizzle the white chocolate over the cooled cookie bars in beautiful zigzag patterns.

Step 6: Final Flourish

Sprinkle fresh blueberries on top.

Add a light dusting of lemon zest for extra zing.

Slice into squares and serve these gorgeous treats to your eager friends and family.

Toss fresh blueberries in a little flour before adding to the batter to prevent them from sinking and maintain even distribution throughout the bars.
Use a fine grater to create delicate lemon zest, ensuring maximum citrus flavor without bitter white pith in your cookie bars.
Check bars at 12 minutes and remove from oven when edges are just golden to maintain a soft, tender texture that melts in your mouth.
Allow white chocolate to cool slightly before drizzling to create beautiful, thin lines instead of thick, clumpy streaks on top of the bars.

Store bars in an airtight container in the refrigerator for up to 5 days. Keep them covered with plastic wrap or parchment paper to prevent drying out.
Wrap individual bars tightly in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
Warm individual bars for 10-15 seconds on medium power. Check to ensure they don't become too hot or lose moisture.
Let frozen or refrigerated bars sit at room temperature for 15-20 minutes to restore their soft texture and bring out the flavors.

FAQs

How do I prevent blueberries from sinking in the batter?

Gently coat blueberries in a little flour before folding them into the batter. This helps them stay suspended and prevents them from sinking to the bottom of the bars.

Can I use frozen blueberries instead of fresh ones?

Yes, but do not thaw them first. Add frozen blueberries directly to the batter to prevent color bleeding and maintain their shape during baking.

How can I get a more intense lemon flavor?

Add an extra teaspoon of lemon zest or replace some of the vanilla extract with fresh lemon juice to enhance the citrusy taste in the cookie bars.
