Crumbl Blueberry Muffin Cookies with Streusel
Soft, cakey blueberry muffin cookies topped with buttery cinnamon streusel and a sweet vanilla glaze, a bakery-style Crumbl copycat you can make at home in under an hour.
The Cookie That Tastes Like a Muffin (In the Best Way)
If you have ever stood in front of the Crumbl weekly menu hoping the blueberry muffin cookie would make a comeback, you already know why this recipe exists. It is soft, it is cakey, it is studded with juicy blueberries, and it is topped with a crumbly cinnamon streusel and a sweet vanilla glaze. Basically, it is a blueberry muffin that decided to become a cookie, and honestly, we are not mad about it.
The best part is that you do not need to wait for a specific day on the Crumbl rotation. This copycat blueberry muffin cookie comes together with pantry staples, a handful of fresh blueberries, and about 40 minutes of your time.
Before we get cooking, the right tools and ingredients make a real difference here. A good cookie scoop keeps every cookie the same size so they bake evenly, and a sturdy hand mixer makes creaming the butter and sugar effortless. Fresh, plump blueberries and real butter also go a long way toward getting that authentic bakery flavor.
What Makes These Blueberry Muffin Cookies So Good
This is not your average drop cookie. A few small details take it from good to genuinely tastes like Crumbl:
- Greek yogurt or sour cream keeps the crumb soft and tender, almost like a cake.
- Flour-coated blueberries stay evenly distributed instead of sinking to the bottom.
- A buttery cinnamon streusel pressed into the top adds crunch and warmth.
- A simple powdered sugar glaze ties everything together with just the right amount of sweetness.
Chef's Tip: Toss your blueberries in a tablespoon of flour before folding them into the dough. This small step keeps the berries from bleeding purple streaks into your dough and helps them stay put instead of sinking.
Getting That Signature Crumbl Texture
Crumbl cookies are known for being thick, soft, and almost underbaked-looking in the center, and that is exactly the texture we are going for here. The trick is twofold: do not overmix the dough once you add the flour, and pull the cookies out of the oven when the edges are just set but the centers still look a little soft. They will continue to cook slightly as they cool on the hot baking sheet, which keeps that irresistible cakey middle intact.
The streusel matters too. Pressing it gently into the top of each dough ball before baking helps it stick and toast slightly in the oven, giving you that classic crumb topping texture in every bite.

Crumbl Blueberry Muffin Cookies with Streusel
Soft, cakey blueberry muffin cookies topped with buttery cinnamon streusel and a sweet vanilla glaze, a bakery-style Crumbl copycat you can make at home in under an hour.
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 cup unsalted butter, softened
- 3/4 cup granulated sugar
- 1 large eggs, room temperature
- 1 tsp vanilla extract
- 1/4 cup plain Greek yogurt, or sour cream, for a cakey texture
- 1 cup fresh blueberries, tossed in 1 tbsp flour to prevent sinking
- 1/2 cup all-purpose flour, for streusel topping
- 3/8 cup brown sugar, packed, for streusel
- 1/2 tsp ground cinnamon, for streusel
- 3 tbsp unsalted butter, melted, for streusel
- 1 cup powdered sugar, for glaze
- 2 tbsp milk, plus more as needed, for 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, stir together the flour, brown sugar, and cinnamon, then mix in the melted butter with a fork until clumpy. Set aside.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large bowl, cream the softened butter and granulated sugar together until light and fluffy, about 2 minutes.
Beat in the egg, vanilla extract, and Greek yogurt until smooth.
Gradually mix the dry ingredients into the wet ingredients until just combined, being careful not to overmix.
Gently fold in the flour-coated blueberries.
Scoop the dough into 12 large balls, about 3 tablespoons each, and place them on the prepared baking sheets.
Flatten each ball slightly and press a generous pinch of streusel topping into the top of each cookie.
Bake for 12 to 14 minutes, until the edges are just set and the tops are lightly golden. The centers should still look soft.
Cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.
Whisk the powdered sugar and milk together until smooth and drizzly, adding more milk a teaspoon at a time if needed.
Drizzle the glaze over the cooled cookies and let it set for a few minutes before serving.
Equipment

Notes
Serving, Storing, and Variations
These blueberry muffin cookies are best enjoyed the day they are glazed, when the streusel is still slightly crisp and the glaze has just set. That said, they hold up beautifully for days if you store them properly.
- Room temperature: Keep glazed cookies in an airtight container for up to 3 days.
- Fridge: For longer storage, refrigerate for up to a week, then let them sit out for 10 minutes before eating.
- Freezer: Freeze the unglazed, baked cookies for up to 2 months. Thaw at room temperature and add fresh glaze before serving.
Want to switch things up? Try swapping the blueberries for raspberries or blackberries, or add a handful of white chocolate chips to the dough for extra sweetness. However you make them, these cookies bring all the charm of a bakery favorite right into your own kitchen, no waiting for a specific day of the week required.
