The image shows flower-shaped layered cookies stacked in piles on a round black cooling rack. Each cookie has three layers with a gradient from purple on top, fading into light lavender in the middle and creamy white at the bottom, all with a smooth texture. The main stack is centered with four cookies, and one cookie leans against it, showing the side layers clearly. In the background, more stacks of these cookies are slightly blurred, all placed on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 cup blueberries (150g)
2 tbsp lemon juice
1 tbsp lemon zest (zest of 1 lemon)
½ cup granulated sugar (100g)
1 pinch citric acid (optional)
1 cup unsalted butter (225g), room temperature
¾ cup powdered sugar (150g)
1 large egg, divided
½ tsp vanilla extract
½ tsp kosher salt
1 ½ tbsp lemon juice
1 tbsp lemon zest (zest of 1 lemon)
3 ⅓ cup all-purpose flour (420g), sifted

Instructions

Step 1: Bring butter to room temperature by removing it from the refrigerator the night before or a few hours before baking.
Step 2: Make the blueberry reduction: In a medium saucepan, combine blueberries, 2 tbsp lemon juice, granulated sugar, lemon zest, and optional citric acid over medium-high heat. Bring to a boil, then remove from heat.
Step 3: Blend the mixture using a blender or immersion blender, then strain through a sieve back into the saucepan.
Step 4: Return to low boil and cook for 7–10 minutes, stirring occasionally until sauce thickens. Remove from heat and cool completely.
Step 5: Prepare cookie dough: In a stand mixer bowl fitted with a paddle attachment, cream together butter and powdered sugar on low speed until combined.
Step 6: Add egg yolk, half of the egg white (reserve the remainder), vanilla extract, salt, 1 ½ tbsp lemon juice, and 1 tbsp lemon zest; mix until combined.
Step 7: Gradually add sifted flour in thirds, mixing just until combined after each addition.
Step 8: Divide dough into 4 equal balls. Set one aside for the plain lemon layer.
Step 9: For the colored layers, knead in blueberry sauce: 2 tbsp in the first ball (darkest layer), 1 ½ tbsp in the second, and ½ to 1 tbsp in the third. Add blue/purple food coloring if desired to intensify colors.
Step 10: Wrap each dough ball and chill in the refrigerator for at least 2 hours.
Step 11: Roll out each dough ball between parchment or plastic sheets to about ⅛-inch thickness.
Step 12: Mix a splash of reserved egg white with a little water to create a “glue” for layering.
Step 13: Layer the doughs starting with the plain lemon layer: brush lightly with the egg white mixture, then add the lightest blueberry layer, brush again, add the next darker layer, brush, and finish with the darkest layer on top. Press gently to remove air bubbles.
Step 14: Use a 2-inch cookie cutter or your preferred shape to punch out cookies and place them 1 inch apart on a parchment-lined or silicon baking tray.
Step 15: Preheat the oven to 350°F (175°C).
Step 16: Freeze the cookie tray for about 10 minutes to solidify cookies before baking.
Step 17: Bake cookies for 7 minutes, then remove and wait 5 minutes. Return tray to the oven, turn oven off, and let cookies finish baking inside for 20 minutes to preserve vibrant colors.
Step 18: Cool cookies completely on a wire rack before serving or storing.

Tips & Variations

Using room temperature butter is crucial for a smooth dough and tender cookies.
Adding a pinch of citric acid enhances the lemon tang but can be omitted if unavailable.
Food coloring is optional but helps intensify the blueberry hues in the dough.
You can substitute frozen blueberries for fresh if needed; just thaw and drain before using.
Try different cookie cutter shapes to match seasonal themes or celebrations.

Storage

Store baked cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze baked cookies for up to 2 months, then thaw at room temperature. To refresh, warm briefly in a low oven. Dough can be refrigerated for up to 3 days before baking or frozen for up to 1 month.

How to Serve

The image shows a white marbled surface with several dough balls in different stages: two small round dough balls at the bottom left, one pale yellow ball, and one pink dough ball at the top left. Near the center is a larger piece of pale dough with a circular indentation filled with dark purple blueberry jam. To the right, there is a clear glass bowl filled with fresh blueberries, and next to it, a halved lemon with bright yellow flesh. In the lower right corner, a white dough scraper rests on the surface. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work well. Thaw and drain excess liquid before making the blueberry reduction to avoid soggy dough.

Why do I need to freeze the cookies before baking?

Freezing helps the cookies keep their shape and vibrant layered colors during baking, preventing the dough from spreading too much.
