Ingredients
Blueberry Sauce
- 1 cup fresh blueberries (stems removed)
- 2 teaspoons granulated sugar
- 1 tablespoon fresh lemon juice (not bottled)
Dry Ingredients
- 2 cups all purpose flour
- 1½ tablespoons cornstarch
- 1½ teaspoons baking powder
- ½ teaspoon kosher salt
Wet Ingredients & Dough
- ½ cup unsalted butter (room temperature)
- 1½ cups granulated sugar (divided, 1¼ cups + ¼ cup)
- 2 tablespoons milk
- 1 large egg
- ¼ teaspoon purple food dye (liquid, optional)
Instructions
- Make the blueberry sauce: In a medium pot over medium-low heat, combine fresh blueberries, sugar, and lemon juice. Cook stirring frequently until the blueberries break down and thicken, about 5-8 minutes. Set aside to cool.
- Combine the dry ingredients: In a large bowl, whisk together flour, cornstarch, baking powder, and kosher salt. Set aside.
- Cream the butter and sugar: In another large bowl, beat the unsalted butter with 1¼ cups of granulated sugar until light and fluffy, about 2-3 minutes.
- Add the blueberry sauce: Scoop 3 tablespoons of the cooled blueberry sauce and fold it into the creamed butter and sugar mixture. Reserve any extra sauce for another use.
- Add remaining liquid ingredients: Mix in milk, the large egg, and purple food dye if using. Stir just until combined.
- Add dry ingredients: Gradually add the dry flour mixture to the wet mixture, stirring gently until just combined and no dry flour remains.
- Chill the dough: Cover the bowl tightly with plastic wrap and refrigerate for 3 hours to firm up the dough and enhance flavor.
- Prep your tools: Preheat oven to 325ºF (163ºC). Line a baking sheet with parchment paper or a Silpat mat and set aside.
- Pour sugar: Place the remaining ¼ cup granulated sugar onto a shallow plate for rolling.
- Form the cookies: Scoop approximately 1 heaping tablespoon of chilled dough and roll it into balls.
- Roll in sugar: Roll each dough ball in the sugar on the plate to coat completely. Place on prepared baking sheet spaced apart (about 6 cookies per sheet).
- Chill the extra dough: Return unshaped dough to refrigerator while baking the first batch or prepare a second baking sheet if available.
- Bake: Bake cookies in preheated oven for 15 minutes or until cracks form on the surface.
- Cool: Remove from oven and allow cookies to cool on baking sheet for 10 minutes before transferring to a wire rack to cool completely for an additional 20 minutes. Handle gently to avoid breaking.
Notes
- Using fresh lemon juice, not bottled, ensures a bright flavor in the blueberry sauce.
- Chilling the dough is essential for proper texture and to prevent spreading during baking.
- Extra blueberry sauce can be saved and used as a topping for pancakes or yogurt.
- Optional purple food dye adds a fun color but can be omitted without affecting taste.
- Handle cookies gently after baking as they are soft when warm.
