Crumbl Blueberry Muffin Cookies with Streusel
Soft, cakey blueberry muffin cookies topped with a buttery cinnamon streusel and a sweet vanilla glaze, a spot-on Crumbl copycat you can bake at home.
The Crumbl Blueberry Muffin Cookie You Can Bake at Home
If you have ever stood in front of the Crumbl case debating between flavors, you already know the pull of the blueberry muffin cookie. It is soft, cakey, studded with juicy berries, and topped with a crumbly streusel that makes it feel more like a bakery muffin than a cookie. This homemade version nails that same experience, and honestly, I think it might even beat the original.
This is one of those recipes that turns a regular afternoon into an event. The smell of cinnamon streusel baking is impossible to ignore, and by the time the vanilla glaze goes on, you will have people wandering into the kitchen asking what smells so good.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy cookie scoop keeps every cookie the same generous bakery size, and a good quality butter makes the streusel taste rich instead of flat. Fresh blueberries in season are wonderful, but a reliable bag of frozen wild blueberries is a great pantry staple for baking year round.
Why This Recipe Works
The magic of a blueberry muffin cookie comes down to three things working together.
- A cakey, muffin-like base. These cookies use a touch more flour and a gentler mixing method than a typical chewy cookie, which gives them that soft, tender muffin texture instead of a crisp cookie snap.
- Real blueberries, not extract. Coating the berries in flour before folding them in keeps them from sinking and bleeding into the dough, so you get little bursts of fruit in every bite.
- A buttery cinnamon streusel. This is the detail that makes people say wait, is this from Crumbl? Pressing the streusel firmly onto the dough before baking helps it stay put instead of crumbling off.
Chef's Tip: Chill your streusel while you mix the cookie dough. Cold streusel holds its shape better in the oven and gives you those satisfying, craggy little crumbs on top instead of a melted layer.
Getting That Bakery Look and Texture
A few small habits separate a good homemade cookie from a true copycat.
- Use a large cookie scoop, roughly a third of a cup per cookie, so you get that generous, bakery style size.
- Do not overmix once the flour goes in. Overmixing develops gluten and turns a cakey cookie chewy and tough.
- Pull the cookies out when the centers still look slightly underbaked. They will continue setting on the hot pan and stay wonderfully soft in the middle.
- Wait until the cookies are completely cool before glazing, or the glaze will slide right off instead of setting into that classic drizzle.
These little details are exactly how to make Crumbl blueberry muffin cookies taste like the real deal instead of just a regular blueberry cookie with a fancy name.

Crumbl Blueberry Muffin Cookies with Streusel
Soft, cakey blueberry muffin cookies topped with a buttery cinnamon streusel and a sweet vanilla glaze, a spot-on Crumbl copycat you can bake at home.
Ingredients
- 2 1/2 cups all-purpose flour, spooned and leveled
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1/2 tsp ground cinnamon, for the cookie dough
- 3/4 cup unsalted butter, softened
- 3/4 cup granulated sugar
- 1/4 cup brown sugar, packed
- 1 large egg, room temperature
- 1 tsp vanilla extract
- 1 cup fresh blueberries, tossed in 1 tbsp flour, or use frozen and do not thaw
- 3/8 cup all-purpose flour, for the streusel topping
- 3 tbsp brown sugar, for the streusel topping
- 1/2 tsp ground cinnamon, for the streusel topping
- 3 tbsp unsalted butter, cold and cubed, for the streusel topping
- 1 cup powdered sugar, for the glaze
- 2 tbsp milk, plus more as needed for the glaze
- 1/4 tsp vanilla extract, for the glaze
Instruction
Preheat the 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 a fork or your fingers until it forms coarse, pea-sized crumbs. Set aside in the fridge.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon for the cookie dough.
In a large bowl, cream the softened butter with the granulated sugar and brown sugar until light and fluffy, about 2 minutes.
Beat in the egg and vanilla extract until fully combined.
Gradually mix the dry ingredients into the wet ingredients until just combined, being careful not to overmix.
Gently fold in the flour-coated blueberries, taking care to keep them mostly whole.
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.
Flatten each dough ball slightly with your palm, then press a generous layer of the chilled streusel firmly onto the top of each cookie.
Bake for 12 to 14 minutes, until the edges are just set and the tops look lightly golden. The centers should still look a touch underbaked.
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, milk, and vanilla extract for the glaze until smooth and drizzly.
Drizzle the glaze generously over the cooled cookies and let it set for a few minutes before serving.

Notes
Serving, Storing, and Variations
These cookies are best served the day they are made, ideally slightly warm, when the streusel is crisp and the inside is soft and pillowy. They pair beautifully with a glass of cold milk or a cup of coffee.
For storage, keep them in an airtight container at room temperature for up to three days. If you want to prep ahead, freeze the unglazed cookies in a single layer, then thaw and add fresh glaze right before serving so it looks freshly made.
Want to switch things up? Try swapping the blueberries for raspberries or diced peaches, or add a handful of white chocolate chips to the dough for an extra layer of sweetness. However you make them, these blueberry streusel cookies are proof that you do not need a Crumbl run to satisfy that craving. Your own kitchen will do just fine.
