- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- 1/4 teaspoon baking soda
- 1/2 cup (1 stick / 113 g) unsalted butter, room temperature
- 3/4 cup (150 g) granulated sugar
- 2 large eggs, room temperature
- 1 tablespoon whole milk, room temperature
- 1 teaspoon vanilla extract

Crumble Topping
- 1/4 cup (31 g) all-purpose flour
- 3 tablespoons granulated sugar
- 1 tablespoon light brown sugar, packed
- 1/4 teaspoon kosher salt
- 2 tablespoons unsalted butter, melted and cooled slightly
Instructions
- Make Blueberry Filling: In a small saucepan over medium heat, combine ½ cup fresh blueberries, 2 teaspoons granulated sugar, and 2 teaspoons lemon juice. Heat for about 5 minutes, stirring occasionally, until the sugar dissolves and the blueberries release their juices.
- Thicken Filling: In a small bowl, whisk together 2 teaspoons cornstarch and 2 teaspoons water until smooth. Slowly add this mixture to the blueberry mixture, stirring constantly, and cook for 1-2 more minutes until the filling thickens to your desired consistency.
- Cool Filling: Remove the blueberry filling from heat and let it cool slightly while preparing the cookie dough.
- Preheat Oven and Prepare Baking Sheet: Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Mix Dry Ingredients: In a medium bowl, whisk together 1 ¾ cups all-purpose flour, 1 teaspoon baking powder, 1 teaspoon kosher salt, and ¼ teaspoon baking soda. Set aside.
- Cream Butter and Sugar: Using a stand mixer fitted with the paddle attachment, beat ½ cup unsalted butter and ¾ cup granulated sugar on medium speed for about 2 minutes until light and fluffy.
- Add Wet Ingredients: Add 2 large eggs, 1 tablespoon whole milk, and 1 teaspoon vanilla extract to the creamed mixture. Mix until fully combined, stopping to scrape down the bowl sides as needed.
- Incorporate Dry Ingredients: Reduce mixer speed to low and gradually add the dry flour mixture. Mix until just incorporated.
- Add Blueberries: Gently fold in 1 cup fresh blueberries into the dough.
- Prepare Crumble Topping: In a small bowl, combine ¼ cup all-purpose flour, 3 tablespoons granulated sugar, 1 tablespoon packed light brown sugar, ¼ teaspoon kosher salt, and 2 tablespoons melted and cooled unsalted butter. Mix until the mixture forms crumbs.
- Assemble Cookies: Spread about half of the cooled blueberry filling over the cookie dough in the bowl without mixing it in. Using a 1½ tablespoon cookie scoop, scoop 8 cookies onto the prepared baking sheet.
- Top Remaining Dough: Spread the remaining blueberry filling over the leftover dough. Scoop the remaining 8 cookies onto the baking sheet, totaling approximately 16 cookies.
- Add Crumble Topping: Spoon crumble topping onto each cookie, pressing gently to adhere.
- Bake: Bake cookies in the preheated oven for 14-16 minutes, until edges are set and lightly browned but centers remain soft.
- Cool Cookies: Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely. Enjoy!
Notes
- Ensure all wet ingredients like eggs and milk are at room temperature for better mixing and texture.
- Do not overmix the dough after adding flour to keep the cookies tender and cake-like.
- Use fresh blueberries for the best flavor; frozen blueberries may add extra moisture and alter texture.
- The crumble topping adds a lovely contrast of texture and subtle sweetness — don’t skip it!
- Store cookies in an airtight container at room temperature for up to 3 days or freeze for longer storage.
