Plum Cookies Recipe: Jammy Fruit Filling in Every Bite

This plum cookies recipe transforms tart plums into a buttery, jammy center that makes every bite unforgettable. The secret lies in baking down plums until they form a concentrated, fruity filling that stays soft yet holds its shape—no soggy centers here.

I perfected this technique after years of experimenting with fruit-filled cookies, and the result is a delicate balance of crisp edges and tender, jam-packed centers that taste like summer in every mouthful.

The dough comes together in just 15 minutes, with a simple combination of flour, butter, and sugar that stays tender without being crumbly. Fresh plums work best when cooked down into a thick purée, but dried plums can be rehydrated for a deeper, more concentrated flavor.

For an extra touch of sophistication, a sprinkle of flaky sea salt on top enhances the natural sweetness of the fruit while adding a sophisticated contrast.

Baking at 350°F for 12-15 minutes ensures the cookies develop a golden, crisp exterior while keeping the plum filling warm and gooey inside. The aroma alone—warm butter, caramelizing sugar, and ripe plums—will fill your kitchen with the kind of cozy, homemade magic that makes these worth every minute of prep.

These aren’t just cookies; they’re a taste of nostalgia wrapped in a delicate, buttery shell.

Perfect for holiday gift-giving, potlucks, or simply treating yourself to something special, these plum cookies freeze beautifully and taste even better the next day. Whether you use fresh summer plums or dried ones from winter, the technique remains the same—delivering that perfect jammy surprise in every bite. Let’s get baking!

Plums are the star, so pick firm but ripe ones—they should yield slightly to gentle pressure. Local farmers markets often have the best selection, but grocery store plums work too if they're vibrant and fragrant. Avoid overripe or mealy plums—they'll turn mushy when baked. For dried plums, soak them in warm water for 1 hour first. The cornstarch trick is non-negotiable—it's what keeps that jammy filling from leaking out and turning your cookies soggy. Trust me, it's worth the extra 30 seconds of mixing.

No fresh plums? Dried plums (prunes) work perfectly—just rehydrate them first. Short on butter? Vegetable shortening keeps the texture tender, though it lacks flavor. Want extra richness? Swap half the butter for heavy cream—it makes the dough ultra-tender. The vanilla and lemon juice might seem small, but they're what elevate the plum flavor from 'good' to 'unforgettable.' If you're feeling fancy, add a pinch of cardamom or orange zest to the dough for a sophisticated twist. And yes, you can use frozen plums—just thaw and drain them first.

These cookies freeze like a dream. Bake them, cool completely, then store in an airtight container for up to 3 months. For extra freshness, keep them in the fridge for up to 1 week—they taste even better the next day as the flavors meld. The filling thickens as it cools, so they're perfect for gifting. Wrap them in parchment-lined boxes with a ribbon for a holiday-worthy treat. Pro tip: Sprinkle the turbinado sugar right after baking while they're still warm for that crunchy contrast.

Step-by-step instructions for plum cookies recipe

Here's how to create these incredible jammy plum cookies with a perfect balance of tender dough and fruit-filled surprises.

Begin by pitting the 2.5 lbs of fresh plums and cutting them into small, even chunks—about ½-inch pieces. The plums should be ripe but still hold their shape when cut. Transfer the plum pieces to a medium bowl and toss them with the 1 tbsp lemon juice and 1 tbsp cornstarch. This mixture prevents the filling from bleeding too much into the dough later.

Let the plum mixture sit for 10 minutes while you prepare the dough. The lemon juice brightens the flavor, and the cornstarch helps thicken the filling so it stays intact in the center of each cookie. You'll notice the plums release a little juice—this is normal and will cook off during baking.

In a large mixing bowl, combine the 1 cup of cold, cubed unsalted butter with the 1 cup of granulated sugar. Using a hand mixer or stand mixer, beat on medium speed until the mixture is light and fluffy—about 2-3 minutes. This step incorporates air into the dough, which helps create that classic cookie texture.

Add the 0.25 cup of heavy cream and 1 tsp vanilla extract, mixing until fully combined. In a separate bowl, whisk together the 3 cups of sifted all-purpose flour, 1 tsp baking powder, 0.5 tsp fine sea salt, and 0.5 tsp ground cinnamon. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix—the dough should come together but still look slightly shaggy.

Using a silicone spatula, gently fold the plum mixture into the dough until it's evenly distributed. The dough will look slightly messy, but that's okay—this ensures each bite has that delicious plum surprise. If the dough feels too sticky, you can add a little more flour, but don't overdo it or the texture will change.

Divide the dough into 24 equal portions (about 1.5 oz each) and roll them into balls. Place them on a parchment-lined baking sheet, spacing them about 2 inches apart. Sprinkle each ball with a pinch of the 0.25 cup turbinado sugar for that classic crunchy topping and extra sweetness.

Preheat your oven to 350°F. Bake the cookies for 12-15 minutes, or until the edges are golden brown and the centers look slightly underdone. The cookies will continue to set as they cool, so don't overbake them. You'll know they're done when the edges are set but the tops still have a soft, pillowy look.

Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes before transferring them to a wire rack. The centers should still be warm and slightly gooey—this is where the magic happens. Serve them warm for the best experience, with a glass of milk or a cup of coffee.

Flavor customization for this dish

Citrus Brightness Boost

Add 1 tbsp orange zest or ½ tsp grated lime zest to the dough for a zesty twist that cuts through the plum's natural sweetness. I find that orange zest pairs especially well—it adds a subtle floral note that makes the cookies taste like a sunny afternoon.

For extra brightness, replace the lemon juice in the plum filling with 1 tbsp lime juice instead. 🍊

Spiced Warmth Variations

Infuse the dough with ½ tsp cardamom or ¼ tsp nutmeg for a cozy, aromatic depth that complements the plums beautifully. I love adding both spices together—they create a warm, almost chai-like complexity.

For a Middle Eastern touch, swap the cinnamon for ½ tsp ground ginger and a pinch of allspice. These spices work best when toasted lightly in a dry pan for 30 seconds before mixing into the dough.

Nutty Crunch Additions

Fold ½ cup chopped walnuts or toasted pecans into the dough for texture contrast. Toast the nuts in a dry skillet over medium heat for 3-4 minutes until fragrant, then chop them finely. I recommend adding them right after mixing in the plums so they distribute evenly.

For extra indulgence, sprinkle ¼ cup chopped candied pecans on top before baking—this adds a sweet, caramelized crunch that balances the tart plums.

Chocolate-Dipped Luxury

Dip half of each cooled cookie into melted dark chocolate (I use 70% cacao) and sprinkle with crushed hazelnuts or flaky sea salt while the chocolate is still wet. The bitterness of the chocolate contrasts perfectly with the plum's jammy sweetness, creating a sophisticated flavor profile.

For a quicker version, melt ½ cup chocolate chips with 1 tbsp coconut oil in 30-second intervals in the microwave, then drizzle over cooled cookies.

Herbal Infusions

Add 1 tsp fresh rosemary or thyme leaves (finely chopped) to the plum filling for an unexpected herbal note that pairs surprisingly well with the fruit. I find rosemary adds an earthy depth, while thyme brings a subtle floral brightness.

For a more pronounced herbal flavor, steep 1 tbsp dried lavender buds in ¼ cup warm water for 10 minutes, then strain and mix the infused water into the plum filling. Use sparingly—lavender can be overpowering!

Boozy Elevations

Swap 1 tbsp of the lemon juice in the plum filling with 1 tbsp brandy or rum for a subtle boozy depth that caramelizes beautifully during baking. I recommend using a good-quality vanilla extract infused with ½ tsp bourbon in the dough for an extra layer of warmth.

For a festive touch, brush the baked cookies with a 50/50 mix of powdered sugar and rum while still warm—let it dry completely before serving. 🍷
