Ingredients You’ll Need

All of these ingredients come together to create an enticing symphony of flavors and textures. Each plays an important role in making sure your Blueberry Crumble Cake Cookies Recipe turns out just right.

• Fresh blueberries: For sweet bursts of juicy flavor inside the cookie and the filling.
• Granulated sugar: Sweetens the dough and the crumble topping perfectly.
• Lemon juice: Adds a bright, tart note that balances the sweetness wonderfully.
• Cornstarch: Thickens the blueberry filling for a luscious texture.
• All-purpose flour: The base for the cookie dough and crumble, providing structure.
• Baking powder and baking soda: Leavening agents that create the perfect tender lift.
• Kosher salt: Enhances all the flavors and balances sweetness.
• Unsalted butter: Adds richness and moisture to dough and crumble alike.
• Eggs: Bind the dough together and keep the cake-like texture tender.
• Whole milk: Moistens the dough, enhancing softness.
• Vanilla extract: Adds warmth and depth to the flavor profile.
• Light brown sugar: Adds caramel notes to the crumble topping.

Ingredient Substitutions & Tips

• Fresh blueberries: Frozen blueberries can be used, but thaw and drain them well to avoid excess moisture.
• Unsalted butter: You may substitute with salted butter—reduce added salt slightly to balance flavors.
• Whole milk: You can swap for buttermilk or any plant-based milk, but note texture differences.
• Light brown sugar: Replace with dark brown sugar for a richer, molasses flavor or white sugar in a pinch.

How to Make Blueberry Crumble Cake Cookies Recipe

Step 1: Prepare the Blueberry Filling

Start by heating fresh blueberries with sugar and lemon juice in a small saucepan over medium heat. This melts the sugar and helps the berries release their sweet juices, forming a natural syrup. Whisk together cornstarch and water separately, then stir this slurry into the berry mixture to thicken it. Cook for an extra 1-2 minutes until luscious and glossy. Remove from heat and let it cool while you prepare the dough.

💡 Pro Tip: Stir constantly after adding cornstarch slurry to avoid lumps and get that perfect jammy consistency.

Step 2: Mix the Dry Ingredients for the Cookies

Whisk together all-purpose flour, baking powder, baking soda, and kosher salt in a medium bowl. This ensures your leavening and seasoning are evenly distributed for uniform rise and flavor.

💡 Pro Tip: Sifting or whisking breaks up any clumps and adds aeration for fluffier cookies.

Step 3: Cream Butter and Sugars

In your stand mixer fitted with a paddle attachment, beat room-temperature butter and granulated sugar on medium speed until light and fluffy. This process incorporates air, making your cookies irresistibly tender and moist.

💡 Pro Tip: Scrape the sides of the bowl occasionally for even mixing and smooth batter.

Step 4: Add Wet Ingredients

Blend in eggs one at a time, then add milk and vanilla extract. Each addition enriches the dough, ensuring a delicate crumb and rich taste.

💡 Pro Tip: Use large eggs and room temperature milk for best blending and dough texture.

Step 5: Combine Wet and Dry Ingredients

Lower mixer speed and gradually add your flour mixture. Mix until just combined to avoid tough cookies. Gently fold in fresh blueberries for pockets of juice within the dough.

💡 Pro Tip: Resist the urge to overmix here — the tender cake-like crumb depends on it!

Step 6: Make the Crumble Topping

Whisk flour, granulated sugar, brown sugar, lemon zest, salt, and melted butter together in a small bowl until it forms crumbly clumps. This topping adds a delightful contrast to the soft cookie and sweet filling.

💡 Pro Tip: Chill the crumble mixture briefly if your kitchen is warm so it stays crumbly and doesn’t melt into the dough.

Step 7: Assemble the Cookies

Spread half of the cooled blueberry filling over the cookie dough in the mixing bowl but don’t mix it in. Use a 1 ½ tablespoon scoop to portion out half the dough onto your lined baking sheet. Then spread the remaining blueberry filling over the leftover dough, scoop out the rest, and place alongside. This layering creates surprise pockets of filling inside each cookie.

💡 Pro Tip: Use your scoop to keep cookies evenly sized for uniform baking.

Step 8: Add the Crumble and Bake

Top each cookie with a spoonful of crumble, gently pressing it into the dough. Bake at 350°F for 14-16 minutes until edges are lightly browned but centers remain soft.

💡 Pro Tip: Check cookies at 14 minutes to prevent overbaking — centers should look just set but still soft.

Step 9: Cool and Enjoy

Let the cookies cool on the baking sheet for a few minutes to set before transferring to a wire rack. The crumble will crisp while the centers remain tender and gooey. Enjoy your Blueberry Crumble Cake Cookies warm or at room temperature with a glass of milk or a cup of tea.

💡 Pro Tip: These cookies taste even better the next day once flavors meld, so don’t be shy to bake ahead.

Common Mistakes to Avoid

Learn from these common pitfalls:

• Overmixing the dough: Leads to tough cookies instead of tender, cake-like bites.
• Using wet or frozen blueberries without drying: Can cause the dough to be too soggy and spread too much.
• Skipping the cornstarch slurry in filling: Leaves your blueberry filling runny and watery.
• Baking too long: Results in dry cookies with hard centers instead of soft cakey texture.
• Not cooling cookies properly: Removing too soon makes crumble toppers fall off or cookies break apart.
• Ignoring room temperature ingredients: Makes mixing difficult and dough tough.

Mixed Berry Medley

Combine blueberries with raspberries and blackberries in both the dough and filling for a wild, colorful berry explosion.

Make Ahead and Storage

Storing Leftovers

Store cooled cookies in an airtight container at room temperature for up to 3 days. Layer parchment paper between them to protect the crumble topping.

Freezing

Freeze baked cookies in a single layer on a baking sheet, then transfer to a freezer-safe bag or container. They keep beautifully for up to 3 months. Thaw at room temperature before serving.

Reheating

Warm cookies for 10-15 seconds in the microwave or 5 minutes in a 300°F oven for that fresh-baked softness and melty filling.

FAQs

Can I use frozen blueberries in this recipe?

Yes! Just thaw and drain them well to avoid excess moisture that could make your dough soggy.

How do I make the crumble topping extra crunchy?

Use cold melted butter and don’t over-mix the crumble ingredients. You can also sprinkle some coarse sugar on top before baking.

Can I make these gluten-free?

Try a 1:1 gluten-free baking flour blend, but be mindful it may slightly alter texture.

What if I don’t have cornstarch?

Arrowroot powder is a great substitute for thickening the blueberry filling just as effectively.

How do I store leftover cookie dough?

Wrap tightly and refrigerate for up to 2 days or freeze for up to 1 month. Thaw in the fridge before baking.

Can I add nuts to the cookies?

Absolutely! Chopped walnuts or pecans in the crumble or dough add a lovely crunch.

Should I flatten cookies before baking?

Use your scoop to shape the dough evenly but no need to flatten; the batter’s cake-like texture bakes into a perfect shape on its own.

Why are my cookies spreading too much?

Make sure butter is just room temperature, not melted. Over-soft butter causes excessive spreading.
