Crumbl Blueberry Muffin Cookies with Streusel
Soft, bakery-style blueberry muffin cookies topped with a buttery streusel crumble, just like the Crumbl Cookie favorite, made easily at home.
The Bakery Cookie That Tastes Like a Muffin
If you have ever stood in line at Crumbl and walked out with a blueberry muffin cookie the size of your palm, you already know why this recipe exists. It is everything a blueberry muffin promises and rarely delivers: soft, buttery, bursting with juicy berries, and finished with a crackly cinnamon streusel and a sweet glaze drizzle. The best part is that you do not need a Crumbl nearby to enjoy one. This copycat blueberry streusel cookie recipe comes together with basic pantry staples and a little patience while the dough chills, and the payoff is a dozen bakery-style cookies that taste like a fresh-baked muffin top in cookie form.
What makes these blueberry muffin cookies so special is the texture contrast. The cookie base stays pillowy soft thanks to creamed butter and a touch of brown sugar, the blueberries pop with brightness in every bite, and that streusel topping adds a buttery, slightly crunchy crumble that mimics the best part of any muffin, the top. A simple milk glaze ties it all together with just enough sweetness.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy cookie scoop keeps your dough balls uniform so they bake evenly, and a good hand mixer makes creaming the butter and sugar effortless. Fresh, firm blueberries (not overripe or mushy) will hold their shape far better once baked. These are the products that genuinely help this recipe shine:
Why This Recipe Works
There are a few small techniques that take this from "good cookie" to "Crumbl dupe":
- Tossing the blueberries in flour keeps them from sinking to the bottom of the cookie and bleeding too much color into the dough.
- Chilling the streusel while you make the dough keeps the crumbs distinct so they bake into little golden nuggets instead of melting flat.
- Slightly underbaking the centers is the secret to that soft, muffin-like crumb Crumbl cookies are known for. They will firm up as they cool.
Chef's Tip: Resist the urge to flatten your dough balls before baking. Crumbl-style cookies are baked tall and a little rounded, which is exactly what gives them that thick, muffin-top texture once they spread.
Ingredient Notes Worth Knowing
A few swaps and substitutions to keep in mind as you shop and bake:
- Lemon zest is optional, but it brightens the blueberry flavor in a way that tastes remarkably close to an actual blueberry muffin. Do not skip it if you have a lemon on hand.
- Brown sugar in both the dough and streusel adds moisture and that warm, slightly caramelized flavor you want in a muffin-style cookie.
- Cold butter is essential for the streusel specifically. Soft butter will turn the crumble into a paste instead of forming those signature crumbs.
This recipe is endlessly adaptable too. Swap the blueberries for raspberries or chopped strawberries for a different fruit-cookie mashup, or add a handful of white chocolate chips to the dough for extra sweetness.

Crumbl Blueberry Muffin Cookies with Streusel
Soft, bakery-style blueberry muffin cookies topped with a buttery streusel crumble, just like the Crumbl Cookie favorite, made easily at home.
Ingredients
- 2 3/4 cups all-purpose flour, spooned and leveled
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt, fine sea salt
- 3/4 cup unsalted butter, softened to room temperature
- 3/4 cup granulated sugar
- 1/4 cup brown sugar, packed, light or dark
- 2 large eggs, room temperature
- 1 1/2 tsp vanilla extract, pure, not imitation
- 1 tsp lemon zest, from about half a lemon, optional but recommended
- 1 1/2 cups fresh blueberries, tossed lightly in 1 tbsp flour to prevent sinking; frozen can be used if not thawed
- 1/2 cup all-purpose flour, for the streusel topping
- 3/8 cup brown sugar, packed, for the streusel topping
- 3 tbsp unsalted butter, cold, cubed, for the streusel topping
- 1/4 tsp ground cinnamon, for the streusel topping
- 1/2 cup powdered sugar, for the glaze, sifted
- 1 1/2 tbsp milk, for the glaze, plus more as needed
Instruction
Preheat your oven to 350 degrees F (175 degrees C) and line two baking sheets with parchment paper.
Make the streusel first: in a small bowl, mix the flour, brown sugar, and cinnamon, then cut in the cold cubed butter with your fingers or a fork until the mixture forms small, pea-sized crumbs. Set aside in the fridge while you make the dough.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
In a large bowl, cream the softened butter, granulated sugar, and brown sugar together with a hand mixer until light and fluffy, about 2 minutes.
Beat in the eggs one at a time, then mix in the vanilla extract and lemon zest until fully combined.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed just until a soft dough forms. Do not overmix.
Gently fold in the flour-coated blueberries by hand, taking care not to crush them.
Scoop the dough into 12 large balls, about 3 tablespoons each, and place them several inches apart on the prepared baking sheets.
Press a generous spoonful of the chilled streusel crumble firmly onto the top of each cookie dough ball.
Bake for 12 to 14 minutes, until the edges are just set and the streusel is lightly golden. The centers will look slightly underdone, that is exactly what you want.
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
While the cookies cool, whisk together the powdered sugar and milk until smooth and drizzly. Add more milk a few drops at a time if it is too thick.
Drizzle the glaze over the cooled cookies in a zigzag pattern and let it set for about 10 minutes before serving.

Notes
Serving and Storing Your Blueberry Muffin Cookies
These cookies are at their absolute best within the first day or two, when the streusel is still slightly crisp and the centers are soft and tender. Let them cool fully before glazing so the drizzle sets properly instead of melting into the streusel.
To store, keep cookies in an airtight container at room temperature for up to 3 days. If you want to stretch their life a bit longer, refrigerate them for up to a week, just bring them to room temperature or give them a few seconds in the microwave before serving so they soften back up.
Chef's Tip: If you are making a big batch for a party or bake sale, freeze the unbaked, streusel-topped dough balls on a tray until solid, then transfer to a freezer bag. You can bake a fresh batch straight from frozen any time the craving hits, just add two to three extra minutes to the bake time.
