Ingredients You’ll Need

Here’s what you’ll need to make your Blueberry Lemon Cookie Bars:

For the Cookie Bars:

• ½ cup butter, softened

• ¾ cup granulated sugar

• 1 egg

• 1 teaspoon vanilla extract

• 1 tablespoon lemon zest

• 2 tablespoons lemon juice (fresh is best!)

• 1½ cups all-purpose flour

• ½ teaspoon baking powder

• ¼ teaspoon salt

• 1 cup fresh or frozen blueberries (if frozen, do not thaw)

For the White Chocolate Drizzle:

• ½ cup white chocolate chips

• 1 teaspoon coconut oil or butter (optional, for smoothness)

How to Make Blueberry Lemon Cookie Bars

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

2. Cream the butter and sugar together until light and fluffy. Add the egg, vanilla, lemon zest, and lemon juice, and mix until smooth.

3. Whisk the dry ingredients (flour, baking powder, salt) in a separate bowl, then gradually mix them into the wet ingredients until just combined.

4. Fold in the blueberries gently so they stay whole and evenly distributed.

5. Spread the batter into your prepared pan and smooth the top.

6. Bake for 25–30 minutes, or until the edges are golden and a toothpick comes out mostly clean.

7. Cool completely before adding the drizzle.

Add the White Chocolate Drizzle

In a microwave-safe bowl, melt white chocolate chips with coconut oil in 20-second intervals, stirring until smooth. Drizzle over the cooled cookie bars using a fork or piping bag. Let the drizzle set before slicing into squares.

Tips for Perfect Cookie Bars

• Use fresh lemon juice and zest for the brightest flavor.

• Don’t overmix the batter — you want soft, chewy bars.

• For a tart kick, add a touch more lemon zest or a few drops of lemon extract.

• Chill the bars before cutting for clean, even slices.

Serving Ideas

Serve these Blueberry Lemon Cookie Bars with tea, lemonade, or iced coffee for a refreshing treat. They’re perfect for brunch, dessert trays, or gifting. For a special twist, serve them warm with a scoop of vanilla ice cream or a dollop of whipped cream.
