After the chaos subsided and I managed to clean up the mess, I finally got back to baking. Despite the hiccup, the cookies turned out to be a massive hit, and now, they’re a staple in my recipe collection.

Ingredients You’ll Need for Jammy Blueberry Cookies

For the Blueberry Jam:

12 oz (340 g) fresh blueberries
1 tbsp (15 ml) lemon juice
1/4 cup (50 g) granulated sugar
1 tsp vanilla extract
1/2 tbsp (4 g) cornstarch

For the Cookie Dough:

1 cup (224 g) unsalted butter, softened
1 1/4 cups (250 g) granulated sugar
1 large egg, room temperature
1 tbsp vanilla extract
2 1/2 cups (313 g) all-purpose flour
1/2 tsp baking powder
1/2 tsp salt

Step-by-Step Instructions

Prepare the Blueberry Jam
Begin by making the jam, which serves as the star ingredient of these cookies. In a medium saucepan, combine the fresh blueberries, sugar, lemon juice, vanilla extract, and cornstarch. Cook the mixture over medium-low heat, stirring occasionally, for about 30-40 minutes. As it cooks, gently mash some of the blueberries to release their juices and create a jammy texture. Once the mixture has reduced to about 1/2 cup and thickened, remove it from the heat and allow it to cool completely.

Prepare the Cookie Dough
In a large mixing bowl, whisk together the flour, baking powder, and salt. Set this dry mixture aside.

In another large bowl, use an electric mixer to cream the softened butter and granulated sugar together until the mixture is light and fluffy, about 2 minutes. Add the egg and vanilla extract, mixing until the ingredients are fully incorporated. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.

Incorporate the Blueberry Jam
Once the blueberry jam has cooled completely, fold it into the cookie dough using a rubber spatula. Be careful not to overmix; the goal is to create beautiful swirls of jam throughout the dough.

Bake the Cookies
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. Using a large cookie scoop, portion out the dough onto the prepared baking sheets, spacing the cookies about 2 inches apart. For an added touch, sprinkle a bit of granulated sugar on top of each dough ball before baking.

Bake the cookies for 10-12 minutes, or until the edges are set but the centers remain slightly undercooked. This will ensure the cookies stay soft and tender. Let them cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Tips for Success

Cool the Jam Completely
It’s crucial to let the blueberry jam cool completely before incorporating it into the dough. If it’s too warm, it can melt the butter in the dough and affect the texture of the cookies.

Don’t Overmix the Jam
To achieve those signature swirls, gently fold the jam into the dough. Overmixing will blend the jam completely, and you’ll lose the beautiful marbled effect.

Storage Tips
Store these cookies in an airtight container at room temperature for up to 3 days. If you’d like to keep them longer, you can freeze them in a sealed container for up to a month. Simply thaw them at room temperature before serving.

Variations to Try for Jammy Blueberry Cookies

Lemon-Blueberry Bliss
For a bright citrusy twist, add 1 tsp of lemon zest to the cookie dough. The combination of lemon and blueberry is always a winner.

Chocolate-Blueberry Fusion
If you’re a chocolate lover, toss a handful of white chocolate chips into the dough along with the jam. The sweetness of the white chocolate complements the tangy blueberry flavor beautifully.

Nutty Addition
For extra crunch, fold in 1/4 cup of chopped pecans or almonds to the dough. The nuts add a delightful texture and nutty flavor.

Perfect for Any Occasion

Picnics and Potlucks
These cookies are a great choice for outdoor events. Their vibrant swirls of blueberry jam make them a visually stunning addition to any dessert table.
