Introduction

Blueberry Coffee Cake Cookies combine the tender crumb of a coffee cake with the convenience of a cookie. Bursting with fresh blueberries and a sweet streusel topping, these treats are perfect for breakfast or an afternoon snack. Their soft texture and fruity jam filling make them a delightful homemade indulgence.

The image shows a stack of crumbly blueberry pastries with three main layers: a base golden crumbly crust, a middle layer filled with vibrant deep purple blueberry jam mixed with whole blueberries, and a top layer of chunky golden crumble dotted with a light drizzle of white icing. The top pastry has a bite taken out, revealing the soft, gooey blueberry filling inside. Fresh blueberries are scattered around the pastries, sitting on a white marbled surface.

Ingredients

6 oz (170 g) fresh blueberries
2 tbsp (25 g) granulated white sugar
1 tbsp fresh lemon juice
1/2 tsp vanilla
3/4 tsp cornstarch
1/2 cup (112 g) unsalted butter, softened
1 cup (220 g) brown sugar, packed
1 cup (125 g) all purpose flour, spooned and leveled
1/4 tsp salt
2 1/2 cups (313 g) all-purpose flour, spooned and leveled
1/2 tsp baking powder
1/2 tsp salt
1 cup (224 g) unsalted butter, softened
1 1/4 cups (250 g) granulated white sugar
1 egg, at room temperature
1 tbsp vanilla
8 oz (226 g) fresh blueberries
Jam from above (blueberry jam)
1 cup (130 g) powdered sugar
3-5 tsp whole milk

Instructions

Step 1: Make the blueberry jam by combining blueberries, sugar, lemon juice, vanilla, and cornstarch in a small pot. Cook over medium-low heat for 25-30 minutes, mashing some berries about 8 minutes in, until thick. Stir frequently near the end to prevent sticking. Transfer to a bowl, cover with plastic wrap, and let cool completely.
Step 2: Prepare the brown sugar streusel by mixing butter and brown sugar in a medium bowl with an electric mixer on high until combined. Add flour and salt, mixing until the mixture looks like large crumbs. Chill in the fridge for 30 minutes.
Step 3: Preheat oven to 350 ℉ (175 ℃). Line two baking sheets with parchment paper.
Step 4: In a large bowl, whisk together the flour, baking powder, and salt. Set aside.
Step 5: In another large bowl, cream softened butter and granulated sugar on high speed with an electric mixer until fluffy, about 2 minutes. Add egg and vanilla, mixing on medium speed until pale and fluffy, about 1-2 minutes.
Step 6: Gradually add the dry ingredients to the wet, mixing on low just until dough comes together. Scrape bowl sides as needed.
Step 7: Push some dough aside to create space, then gently fold in fresh blueberries using a rubber spatula.
Step 8: Use a spoon to make small indentations in the dough and add half the blueberry jam into the holes. Fold jam gently into dough without fully mixing.
Step 9: Flatten dough with a spatula, create indentations again, and add the remaining jam. Fold gently again to create swirls.
Step 10: Scoop dough with a 2-tablespoon cookie scoop onto baking sheets. Use a tablespoon to make a small indent in each dough ball.
Step 11: Top each cookie with a heaping tablespoon of streusel, pressing gently to adhere. Return any fallen crumbs on top.
Step 12: Bake for 12 minutes. Remove from oven and use a circular cutter slightly larger than the cookies to shape and thicken them by pressing around each cookie. Return to oven and bake for 2 more minutes.
Step 13: Let cookies cool on baking sheets for at least 10 minutes to firm up, then transfer to a rack to cool completely.
Step 14: Mix powdered sugar with 3 teaspoons of milk in a small bowl, adding more milk until the icing is pourable but not runny.
Step 15: Drizzle icing over cooled cookies and enjoy!

Tips & Variations

Use a gentle folding technique with the jam to create beautiful swirls without fully blending, which preserves the burst of berry flavor in each bite.
For a dairy-free option, substitute butter with a plant-based alternative and use almond or oat milk for the icing.
Chilling the streusel helps it hold together better during baking, giving a perfect crumbly topping.
Fresh blueberries can be substituted with frozen ones (do not thaw to avoid adding excess moisture), just add them gently to the dough.

Storage

Store cooled cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze the cookies in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Thaw at room temperature before icing. Reheat gently in a microwave for 10-15 seconds if you prefer them warm.

How to Serve

FAQs

Can I use frozen blueberries instead of fresh?

Yes, you can use frozen blueberries, but it’s best not to thaw them before adding to the dough to avoid extra moisture that can affect texture. Fold them in gently while still partially frozen.

Why do I need to shape the cookies with a cutter after baking?

This step helps the cookies maintain a thick, round shape and prevents excessive spreading, ensuring a soft center with a crisp edge—key to the coffee cake cookie texture.
