Ingredients
- All-Purpose Flour: Provides the essential structure and soft foundation for the dough.
- Baking Soda & Baking Powder: Work together as powerful leavening agents to ensure proper spread and rise.
- Cinnamon: Infuses a warm, spiced undertone reminiscent of classic crumb cake.
- Unsalted Butter: Delivers a rich, tender crumb while acting as a crucial binding fat.
- Brown Sugar & Granulated Sugar: Granulated adds crisp sweetness, while the molasses in brown sugar guarantees a chewier, deeply flavored texture.
- Eggs: Act as the primary binder, holding the heavy crumb and fruit inclusions together.
- Vanilla Extract & Salt: Elevate and balance the overall flavor profile.
- Fresh Blueberries: Add sweet, tart bursts of moisture without weeping excessively into the dough.
- Confectioners’ Sugar: Creates a smooth, easily drizzle-able icing base.
- Water: Thins the icing to your exact desired consistency.
Tips To Get Your Recipe Right
- Measure Accurately: Always use a digital kitchen scale for your dry ingredients. Scooping by volume often packs too much flour, leading to dense, dry cookies.
- Mind the Temperature: Ensure your butter is properly softened to room temperature so it creams seamlessly with the sugars. Avoid melted butter, which causes flat cookies.
- Fold Gently: When adding the fresh blueberries, use a light hand. Over-mixing at this stage will crush the fruit and turn your beautiful dough purple and soggy.
- Use the Right Fruit: Stick exclusively to fresh blueberries. Frozen berries hold excess water that will compromise the thick, chewy texture of your baked goods.
- Space Them Out: Bake one sheet tray at a time on the middle rack of your oven to guarantee even heat distribution and perfectly baked centers.
- Indent the Dough: Use the back of your cookie scoop to gently press an indentation into each dough ball before adding the crumb topping, ensuring it stays in place while baking.
Storage Tips
- Room Temperature: Store baked and cooled cookies in an airtight container at room temperature for up to 3 days.
- Layering: If stacking the iced cookies, place a sheet of parchment or wax paper between the layers to prevent the icing from sticking.
- Freezing Dough: You can freeze the unbaked, scooped dough balls (without the crumb topping) in a freezer-safe bag for up to two months. Add the crumb topping right before baking.
- Freezing Baked Cookies: To freeze fully baked cookies, hold off on the vanilla icing. Freeze them in an airtight container for up to a month, then thaw and drizzle with fresh icing before serving.
FAQs
Can I use frozen blueberries instead of fresh?
It is highly recommended to use fresh blueberries. Frozen berries introduce too much moisture into the dough as they thaw, which can result in a soggy, flat cookie.
Why did my cookies spread too much?
This usually happens if the butter was melted instead of softened, or if the flour was under-measured. Using a kitchen scale is the best way to prevent flat cookies.
Do I have to chill the dough?
Not at all! This recipe is formulated to be scooped and baked immediately, saving you precious time in the kitchen.
Can I use salted butter?
Yes, you can substitute salted butter if that is what you have on hand. Just make sure to completely omit the additional 1/2 teaspoon of salt from the cookie dough recipe to avoid an overly salty flavor.
How do I adjust the icing consistency?
The vanilla icing starts out quite thick. Gradually add tiny splashes of water, mixing thoroughly between additions, until it reaches a smooth, drizzle-friendly texture.

Ingredients
- For the Cookie Dough
390 g (3 1/4 cups) All-Purpose Flour
226 g (1 cup) Softened Unsalted Butter
200 g (1 cup) Brown Sugar
200 g (1 1/3 cups) Fresh Blueberries
50 g (1/4 cup) Granulated Sugar
2 Whole Eggs
1 tsp Baking Powder
1 tsp Ground Cinnamon
1 tsp Vanilla Extract
1/2 tsp Baking Soda
1/2 tsp Salt
- For the Crumb Topping
120 g (1 cup) All-Purpose Flour
70 g (5 tbsp) Melted Unsalted Butter
66 g (1/3 cup) Brown Sugar
1/2 tsp Ground Cinnamon
1/8 tsp Salt
- For the Vanilla Icing
60 g (1/2 cup) Confectioners' Sugar
2 tsp Water
1/4 tsp Vanilla Extract
Directions
- Crumb Topping
- Whisk together the all-purpose flour, brown sugar, ground cinnamon, and salt in a medium-sized mixing bowl.
- Pour in the melted butter, tossing the mixture together until fully moistened.
- Using your fingers, pinch the mixture to form distinct, coarse crumbs. Set this aside for later.
- Cookie Dough
- Prepare your workspace by preheating the oven to 350°F and lining your baking trays with parchment paper.
- In a separate, small mixing bowl, thoroughly whisk the all-purpose flour together with the baking powder, ground cinnamon, baking soda, and salt. Leave this dry mixture to the side.
- In the bowl of a stand mixer equipped with a paddle attachment, beat the softened unsalted butter along with both the brown and granulated sugars. Cream them together until the mixture appears pale and fluffy.
- Incorporate the eggs one by one, followed by the vanilla extract, blending just until incorporated. Be sure to scrape down the edges of the bowl with a rubber spatula.
- Dump the dry flour mixture into the wet ingredients all at once. Pulse the mixer on its lowest speed until mostly blended, leaving a few visible flour streaks. Carefully tumble in the fresh blueberries, mixing gently on low just until dispersed. Stop immediately to avoid crushing the fruit and turning the batter blue.
- Portion out the dough using a 3-tablespoon cookie scoop, placing the mounds on your prepared trays. Use the rounded back of the scoop to press a shallow well into the top of each dough portion. Pack roughly 1 tablespoon of your prepared crumb topping firmly into each indentation.
- Transfer the trays to the oven and bake for roughly 12 minutes. Once baked, allow the cookies to rest and firm up directly on the hot baking sheets.
- Vanilla Icing
- Grab a small bowl and stir the confectioners' sugar, water, and vanilla extract until smooth. This glaze should be fairly thick, but if you prefer a looser drizzle, incorporate tiny drops of extra water until the right texture is achieved.
- Generously zigzag the icing over the fully cooled blueberry cookies before serving.
