These Lemon Blueberry Swirl Cookies are soft, lightly crisp at the edges, and filled with ribbons of thick blueberry swirl. Fresh lemon zest gives the dough a clean citrus flavor, while the glaze adds a simple finish. The combination of lemon and blueberry creates a balanced cookie that is sweet without being heavy. The marbled swirl also gives each cookie a bakery-style look without complicated steps.

Ingredients
Blueberry Swirl
Lemon Cookie Dough
Lemon Glaze
Instructions
Blueberry Swirl
In a small saucepan over medium heat, combine blueberries, sugar, and lemon juice.
Cook 5–7 minutes, stirring occasionally, until berries break down.
Stir in cornstarch slurry and cook 1–2 more minutes until very thick.
The swirl should be thick like jam, not runny.
Remove from heat and cool completely.
Measure out ⅓–½ cup for the dough.
Lemon Cookie Dough
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
In a large bowl, cream butter, brown sugar, and granulated sugar until light and fluffy (2–3 minutes).
Mix in lemon zest, lemon juice (if using), and vanilla.
Beat in egg until fully combined.
In a separate bowl, whisk flour, salt, baking soda, and baking powder.
Gradually mix dry ingredients into wet ingredients until just combined.
Gently fold or lightly swirl in ⅓–½ cup blueberry mixture. Do not fully mix — you want visible streaks.
Cover and chill dough 30–60 minutes.
Chilling is recommended for thicker cookies with less spread.
Scoop 2-tablespoon portions onto baking sheet, spacing 2 inches apart.
Bake 13–15 minutes, until edges are lightly golden and centers look slightly soft.
Cool on baking sheet 5 minutes, then transfer to a wire rack.
Lemon Glaze
Whisk powdered sugar and 1 tablespoon lemon juice.
Add more lemon juice a few drops at a time until drizzle consistency.
Once cookies are completely cool, drizzle glaze over top.
Let set 20–30 minutes before serving.
Tips for Success
Chill the Dough
Chilling for 30–60 minutes helps control spread and improves texture.
Don't Overbake
Remove the cookies when the centers still look slightly soft. They will continue to set on the baking sheet.
Add Swirl on Top
Press a small spoonful of blueberry mixture onto each dough ball before baking for a more defined pattern.
Keep the Swirl Thick
The blueberry mixture should cook down until it resembles jam. If it is too thin, it will blend fully into the dough and lose the marbled look.
Equipment
Storage & Make-Ahead
Room Temperature Store in an airtight container at room temperature for up to 3 days.
Refrigerator Refrigerate in an airtight container for up to 5 days. Let chilled cookies come to room temperature before serving for the best texture.
Freezer Cookie dough can be portioned and frozen for up to 2 months. Bake directly from frozen, adding 1–2 minutes to the baking time.
Troubleshooting
| Problem | Likely Cause | Solution |
|---|---|---|
| Blueberry swirl disappeared into the dough | Swirl mixture was too thin or was overmixed into the dough | Cook the blueberry mixture until it is thick like jam. When folding into the dough, only fold a few times and stop while streaks are still visible. |
| Cookies spread too flat | Butter too warm or dough not chilled | Make sure butter is softened but not melted. Chill the dough for 30–60 minutes before scooping. |
| Cookies are tough or dense | Overmixed dough or too much flour | Mix just until the dry ingredients are incorporated. Measure flour by spooning into the cup and leveling off. |
| Glaze is too thick | Not enough lemon juice | Add lemon juice a few drops at a time until you reach a drizzle-able consistency. |
| Glaze is too runny | Too much lemon juice | Add more powdered sugar a tablespoon at a time until thickened. |
