Crumbl Blueberry Muffin Cookies with Streusel
Soft, bakery-style Crumbl blueberry muffin cookies loaded with juicy berries and topped with a buttery cinnamon streusel and sweet vanilla glaze.
The Bakery Treat You Didn't Know You Needed at Home
If you have ever stood in line at Crumbl just to get your hands on their blueberry muffin cookie, you already know the appeal. It is soft, cakey, studded with juicy blueberries, and finished with a crumbly cinnamon streusel and a sweet glaze drizzle. The good news is you do not need a trip to the mall to enjoy one. This homemade Crumbl blueberry muffin cookie copycat delivers that same bakery magic right from your own kitchen, and it is easier than you might think.
Think of this as a blueberry muffin and a soft sugar cookie that fell in love. You get all the cozy, cinnamon-kissed streusel topping of a muffin, baked into a giant, pillowy cookie. It is the kind of treat that disappears fast whenever I set a plate of these out for family or friends.
Before we get cooking, the right tools and ingredients make a real difference here. A good stand mixer helps you cream the butter and sugar to the right fluffy texture, a sturdy cookie scoop keeps every cookie uniform so they bake evenly, and using real butter along with fresh, plump blueberries gives you that true bakery flavor instead of something flat or artificial.
What Makes These Blueberry Streusel Cookies So Special
This is not your average drop cookie. A few details set this blueberry muffin cookie apart from a basic blueberry cookie recipe:
- A thick, muffin-like dough. These cookies are scooped large and baked into soft, domed rounds, just like a bakery muffin top.
- A buttery cinnamon streusel. Pressed right onto the dough before baking, it turns golden and slightly crisp while the inside stays soft.
- A simple vanilla glaze. Drizzled on after baking, it adds just the right touch of sweetness without overpowering the fruit.
Chef's Tip: Toss your blueberries in a spoonful of the flour from the recipe before folding them into the dough. This keeps them from sinking to the bottom and prevents the dough from turning an unappetizing shade of blue-gray.
Tips for Getting That Crumbl-Style Texture
The secret to a great Crumbl cookie blueberry muffin copycat is all about texture contrast. You want soft, tender cake-like cookie underneath a slightly crunchy streusel top. Here is how to nail it every time:
- Use room temperature butter and eggs so everything creams together smoothly.
- Do not overmix once the flour goes in, this keeps the cookies tender instead of tough.
- Keep your streusel cold until it goes onto the dough, this helps it hold its crumbly texture instead of melting flat in the oven.
- Slightly underbake rather than overbake. Pull the cookies when the centers still look a touch soft, they will finish setting as they cool.
These small details are exactly how to make Crumbl blueberry muffin cookies taste like the real thing, rather than just an ordinary blueberry cookie.

Crumbl Blueberry Muffin Cookies with Streusel
Soft, bakery-style Crumbl blueberry muffin cookies loaded with juicy berries and topped with a buttery cinnamon streusel and sweet vanilla glaze.
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
- 1 1/2 cups fresh blueberries, or frozen, tossed in 1 tbsp flour
- 1/2 cup all-purpose flour, for the streusel
- 3/8 cup brown sugar, packed, for the streusel
- 1/2 tsp ground cinnamon, for the streusel
- 3 tbsp unsalted butter, cold, cubed, for the streusel
- 1 cup powdered sugar, sifted, for the glaze
- 2 tbsp milk, plus more as needed, for the glaze
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, combine the flour, brown sugar, and cinnamon. Cut in the cold cubed butter with a fork or your fingers until the mixture forms coarse, pea-sized crumbs. Set aside in the fridge.
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 until light and fluffy, about 2 minutes.
Beat in the eggs one at a time, then mix in the vanilla extract until fully combined.
Gradually add the dry ingredients to the wet mixture, mixing on low speed just until no streaks of flour remain.
Gently fold in the flour-coated blueberries, being careful not to overmix or crush the berries.
Scoop the dough into 12 large balls, about 1/3 cup each, and place them on the prepared baking sheets, spacing them a few inches apart.
Press each dough ball down slightly and generously top with the chilled streusel mixture, pressing lightly so it adheres.
Bake for 12 to 14 minutes, until the edges are set and lightly golden but the centers still look soft.
Let the cookies cool on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
While the cookies cool, whisk together the powdered sugar and milk until smooth and pourable, adding more milk a teaspoon at a time if needed.
Drizzle the glaze generously over the cooled cookies and let set for a few minutes before serving.
Equipment

Notes
Serving, Storing, and Make-Ahead Tips
These cookies are best enjoyed the same day they are glazed, still slightly warm with the streusel adding a little crunch against the soft muffin-like center. That said, they hold up beautifully for days if you need to plan ahead.
- Room temperature: Store glazed cookies in an airtight container for up to 3 days.
- Freezer friendly: Freeze unglazed, unbaked dough balls topped with streusel for up to 2 months. Bake straight from frozen, just add a minute or two to the bake time.
- Reheating: Warm leftover cookies in the microwave for about 10 seconds to bring back that fresh-baked softness.
Chef's Tip: If you are serving these for a brunch or gathering, a light dusting of extra powdered sugar right before serving makes them look even more like a bakery display case treat.
Variations to Try
Once you have mastered the base recipe, there is plenty of room to play. Swap the blueberries for raspberries or diced strawberries for a different fruity twist, or add a handful of lemon zest to the dough for a bright, muffin-shop flavor boost. However you make them, these blueberry streusel cookies are guaranteed to become a new favorite in your baking rotation, one that rivals anything you would find behind the bakery counter.
