These cookies are the perfect balance of sweet, tangy, and creamy. With bright lemon flavor, melt-in-your-mouth texture, and creamy white chocolate chips, they’re a bakery-style treat that stays soft for days.

Ingredients
For the Cookies:
- 1¼ cups granulated sugar
- 1 Tbsp lemon zest (use more for a stronger lemon flavor)
- ¾ cup unsalted butter, softened
- 3 cups all-purpose flour, spooned and leveled
- 1 tsp cornstarch
- ½ tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- 1 large egg, room temperature
- ½ cup sour cream, room temperature
- 1 Tbsp freshly squeezed lemon juice
- 1 tsp lemon extract
- 1 tsp vanilla extract
- 1 cup white chocolate chips (plus extra for topping)
For the Lemon Glaze (Optional):
- ¼ cup granulated sugar
- 2 Tbsp freshly squeezed lemon juice
Instructions
- Infuse the sugar with lemon zest
In the bowl of a stand mixer, combine granulated sugar and lemon zest. Rub the mixture between your fingers to release the lemon oils and create aromatic lemon sugar. - Cream the butter and sugar
Add the softened butter to the lemon sugar. Beat on medium speed for 2–3 minutes, scraping down the sides as needed, until light and fluffy. - Mix dry ingredients
In a separate bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt. Set aside. - Add wet ingredients
To the creamed butter mixture, add the egg, sour cream, lemon juice, lemon extract, and vanilla extract. Beat until fully combined. - Combine dry and wet ingredients
Gradually add the dry ingredients to the wet mixture, mixing on low speed just until the dough comes together. Do not overmix. - Add white chocolate chips
Using a spatula, gently fold in the white chocolate chips until evenly distributed throughout the dough. - Chill the dough
Cover the bowl and refrigerate for at least 1 hour. The dough is sticky due to the sour cream, so chilling helps firm it up and enhances the flavor. - Preheat and prepare baking sheets
Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper. - Shape the cookies
Scoop about 2 tablespoons of dough per cookie. Roll each ball in granulated sugar to coat, then place on the prepared baking sheet. Press down slightly to flatten. - Bake
Bake for 8–10 minutes, until the edges are just set and the centers look slightly underbaked. Avoid overbaking to keep the cookies soft and moist. - Add the lemon glaze
While the cookies bake, whisk together the granulated sugar and lemon juice for the glaze. When cookies come out of the oven, gently brush the glaze over the tops to lock in flavor and moisture. Press a few extra white chocolate chips on top and add lemon zest for garnish, if desired. - Cool and serve
Allow cookies to cool on the baking sheet for a few minutes, then transfer to a parchment-lined wire rack to finish cooling.
