Ingredients

For the Cookie Bars

2 cups all-purpose flour
1 tsp baking powder
¼ tsp salt
½ cup unsalted butter, softened
¾ cup granulated sugar
1 large egg
1 tsp vanilla extract
2 tbsp fresh lemon juice
1 tbsp lemon zest
1½ cups fresh blueberries (or frozen, not thawed)

For the Lemon Glaze

1 cup powdered sugar
2–3 tbsp fresh lemon juice
1 tsp lemon zest

Instructions

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper.

Step 2: Mix Dry Ingredients

In a bowl, whisk together the flour, baking powder, and salt.
Set aside.

Step 3: Make the Batter

In a large bowl, beat the softened butter and sugar until light and fluffy.
Add the egg, vanilla extract, lemon juice, and lemon zest.
Mix until smooth.

Step 4: Combine

Gradually add the dry ingredients to the wet mixture.
Stir just until combined.
Gently fold in the blueberries without crushing them.

Step 5: Bake

Spread the batter evenly into the prepared pan.
Bake for 28–35 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out mostly clean.

Step 6: Cool

Let the bars cool completely in the pan before glazing.

Step 7: Make the Glaze

Whisk together powdered sugar, lemon juice, and lemon zest until smooth.
Drizzle generously over the cooled bars.

Step 8: Slice & Serve

Cut into bars or squares.
Garnish with extra lemon zest if desired and enjoy!

Tips

Toss blueberries with 1 teaspoon flour before folding them into the batter to prevent sinking.
Fresh lemon juice gives the best flavor.
Allow the glaze to set for 15–20 minutes before slicing for neat bars.
Store in an airtight container for up to 4 days, or refrigerate for up to 1 week.

Yes! Use them straight from the freezer without thawing.

Can I make these ahead of time?
Absolutely. They taste even better the next day after the flavors meld together.

Can I freeze them?
Yes. Freeze (without glaze if possible) for up to 2 months. Thaw overnight in the refrigerator before serving.
