1cup2 sticks unsalted buttermelted and slightly cooled
1cupgranulated sugar
¼cuplight brown sugar
1large egg
1tablespoonlemon juicefresh is best
1teaspoonvanilla extract
2 ½cupsall-purpose flour
1teaspoonbaking soda
½teaspoonsalt
Zest of 1 lemon
1cupfresh or frozen blueberries
¾cupwhite chocolate chips
Instructions
Preheat oven to 350°F.
Line a baking sheet with parchment paper.
In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Stir in the egg, lemon juice, and vanilla extract.
Add flour, baking soda, salt, and lemon zest (if using). Stir just until a dough forms.
Gently fold in blueberries and white chocolate chips. Be careful not to overmix — especially if using fresh berries.
Drop heaping tablespoons of dough onto the baking sheet, leaving 2 inches between each cookie.
Bake for 12–14 minutes, until the edges are lightly golden and the centers are just set.
Let cookies cool on the pan for 5 minutes before transferring to a wire rack.
Notes
Don’t overmix: Be gentle when stirring the dough, especially if you’re using fresh blueberries, to avoid breaking the berries and making the dough streaky.
Pat dry fresh blueberries: Carefully dry fresh berries with a paper towel before adding them so there isn’t too much extra moisture.
Let butter cool: Melt the butter just until smooth, then let it cool slightly before mixing so it doesn’t scramble the egg.
Freeze leftover dough: Bake a few cookies at a time and freeze the rest of the dough to enjoy fresh cookies whenever you’d like.
Use parchment paper: Lining your baking sheet makes cleanup easier and helps the cookies bake evenly without sticking.
Space cookies properly: Leave about 2 inches between each scoop of dough so the cookies have room to spread without merging together.
Check early: Start checking the cookies at the 12-minute mark since oven temperatures can vary — you want golden edges with soft centers.
Cool before moving: Let cookies rest on the baking sheet for a few minutes before transferring them to a rack, which keeps them from falling apart.
