This blueberry cookie recipe transforms sweet, jammy blueberries into delicious treats that taste just like miniature blueberry pies. Each bite delivers soft, chewy goodness with pops of intense blueberry flavor that will have everyone reaching for seconds.
I first made these during blueberry season last summer when my kitchen was overflowing with berries. What started as a creative way to use extra fruit quickly became my most requested dessert for family gatherings and potlucks.
Ingredients
- Fresh blueberries: essential for creating the rich jammy filling that makes these cookies special
- Cornstarch: thickens the blueberry filling to the perfect consistency preventing soggy cookies
- Lemon juice: brightens the blueberry flavor and balances the sweetness
- Vanilla extract: enhances both the jam and cookie dough with warm aromatic notes
- Butter: use unsalted and properly softened for the ideal cookie texture
- Granulated sugar: provides sweetness and helps create crisp edges
Step-by-Step Instructions
- Make the Blueberry Jam:
- Cook blueberries, sugar, lemon juice, vanilla and cornstarch over medium-low heat for 30-40 minutes, stirring occasionally. The mixture should reduce dramatically and become thick enough that when you draw a spoon through it, the path remains visible for a moment. About 15 minutes into cooking, gently crush some berries with the back of a wooden spoon to release more juice. Cool completely before adding to cookie dough.
- Prepare the Cookie Dough:
- Cream butter and sugar together until light and fluffy, taking a full two minutes. This incorporates air into the mixture creating a tender cookie. Add the egg and vanilla, mixing until the batter becomes noticeably paler and increases in volume. The proper creaming technique here is crucial for the right cookie texture.
- Combine Dry and Wet Ingredients:
- Add the flour mixture gradually to the butter mixture, mixing just until incorporated. Overmixing develops gluten, making cookies tough rather than tender. Use a gentle touch when incorporating the dry ingredients, stopping as soon as no dry spots remain.
- Fold in Blueberry Jam:
- Use a rubber spatula to gently fold in the cooled blueberry jam with just a few strokes. The goal is to create beautiful streaks of jam throughout the dough, not to fully incorporate it. This creates pockets of intense blueberry flavor in the finished cookies.
- Scoop and Bake:
- Use a cookie scoop for even sizing, placing only six cookies per sheet to allow proper spreading. The sprinkle of sugar on top creates a subtle sparkle and extra sweetness that complements the jammy blueberries. Bake just until the edges begin to set but centers still look slightly underdone for perfectly soft cookies.

The blueberry jam is truly the star of this recipe. I discovered by accident that allowing it to cool completely before folding into the dough creates those beautiful purple streaks instead of turning the entire cookie blue. This happy accident has become my signature touch when making these cookies.
Storage Information
These blueberry cookies stay fresh in an airtight container at room temperature for up to 3 days. If you notice them beginning to dry out, add a slice of bread to the container to help maintain moisture. For longer storage, refrigerate for up to a week or freeze for up to three months. When freezing, place parchment paper between layers to prevent sticking.
Seasonal Variations
While fresh blueberries create the best flavor, this recipe adapts beautifully to different seasons. In winter, use frozen blueberries without thawing first, though you may need to increase the cooking time slightly for the jam. During summer, try substituting other berries like raspberries or blackberries for delicious variations. For extra decadence, add white chocolate chips to the dough before folding in the jam.
Serving Suggestions
These cookies shine when served slightly warm, about 10 seconds in the microwave brings back that fresh-baked texture. Pair them with vanilla ice cream for an elevated dessert, or serve alongside afternoon tea. For brunch gatherings, arrange them on a platter with lemon scones and fresh fruit for a beautiful spread that will impress guests.
