These jam-stuffed sugar cookies pair a buttery sugar dough with a pocket of strawberry jam and a sweet vanilla glaze topped with sprinkles. Mix dry ingredients into creamed butter and sugars, sandwich 1/2 teaspoon jam between flattened dough rounds, seal edges well, and bake 12 minutes at 350°F. Yield about 20 cookies; chill dough for neater shaping and prevent leaks by sealing edges firmly.
My sister called me at midnight on a Tuesday to tell me she was craving childhood, and I knew exactly what she meant because I had been staring at a jar of strawberry jam and a bag of flour for twenty minutes already. Pop Tarts were the forbidden fruit of our house growing up, something my mother dismissed as candy disguised as breakfast, which only made them more mythical. These cookies are my way of reclaiming that glossy frosted rectangle on my own terms, with real butter and no foil wrapper required.
I brought a batch of these to a potluck last spring and watched a grown man eat six of them while telling me about his Saturday morning cartoon rituals. Something about that familiar strawberry filling tucked inside a soft sugar cookie unlocks a specific kind of joy that nobody pretends to be too cool for.
Ingredients
- All-purpose flour (2 1/2 cups, 315 g): The backbone of the cookie, and spooning it into the cup rather than scooping prevents dense little hockey pucks.
- Baking powder (1/2 teaspoon): Just enough lift to keep the cookies soft without making them cakey.
- Salt (1/2 teaspoon): Brings out the butter and keeps the sweetness honest.
- Unsalted butter, softened (1 cup, 225 g): Real butter is nonnegotiable here because the flavor carries the entire dough, so pull it out of the fridge an hour ahead.
- Granulated sugar (3/4 cup, 150 g): Gives the cookie its crisp edge and clean sweetness.
- Packed light brown sugar (1/4 cup, 50 g): A small amount that adds warmth and chew to the texture.
- Large egg: Binds everything together and contributes to that tender crumb.
- Vanilla extract (2 teaspoons): Split between dough and glaze, it rounds out the strawberry flavor beautifully.
- Strawberry jam (1/2 cup, 160 g): Use a quality brand you would happily eat on toast because it is the star of the filling.
- Powdered sugar (1 cup, 120 g): Creates that signature Pop Tart glaze that sets up smooth and sweet.
- Milk (2 tablespoons): Thins the glaze to the perfect spreading consistency.
- Red or pink food coloring (optional): A drop or two gives the glaze that iconic rosy hue.
- Rainbow sprinkles: The finishing touch that makes these impossible to look at without smiling.
Instructions
- Get your oven ready:
- Preheat to 350°F (175°C) and line two baking sheets with parchment paper so nothing sticks and cleanup is effortless.
- Whisk the dry team:
- In a medium bowl, whisk together the flour, baking powder, and salt until evenly combined and you see no clumps.
- Cream the butter and sugars:
- Beat the softened butter with both sugars in a large bowl until the mixture turns pale, fluffy, and smells like warm caramel, then beat in the egg and vanilla until just incorporated.
- Bring the dough together:
- Gradually add the dry ingredients to the wet on low speed, mixing only until the last streak of flour disappears into a soft, cohesive dough.
- Stuff and shape:
- Scoop one tablespoon of dough, flatten it in your palm, dollop half a teaspoon of strawberry jam in the center, then cap it with another tablespoon of dough and pinch the edges shut before gently rolling into a ball.
- Arrange and bake:
- Space the filled dough balls two inches apart on your prepared sheets and bake for 12 minutes until the edges are lightly golden but the centers still look soft.
- Cool properly:
- Let the cookies rest on the baking sheet for five minutes to firm up, then transfer to a wire rack to cool completely before glazing.
- Glaze and celebrate:
- Whisk powdered sugar, milk, vanilla, and food coloring if using until smooth and thick enough to coat the back of a spoon, then spread over cooled cookies and shower with sprinkles.
One rainy afternoon my niece sat on the kitchen counter and demanded we make pink cookies, and these were the result of that gentle ultimatum. She licked the glaze off every single one before eating the cookie beneath, and honestly I understood the impulse completely.
Jam Swaps Worth Trying
Raspberry jam brings a tartness that cuts through the sweet glaze in a way that tastes almost sophisticated, which is a strange word to apply to something covered in rainbow sprinkles. Blueberry jam turns the filling a deep violet and pairs wonderfully with a tiny pinch of cinnamon added to the dough. Apricot preserves create a milder, more grown up flavor that still looks beautiful under that familiar pastel frosting.
Storage That Keeps Them Right
These cookies keep beautifully in an airtight container at room temperature for up to four days, though the glaze will soften slightly over time as it interacts with the moisture from the jam. If you stack them, place a sheet of parchment between layers so the frosting does not smear onto the bottom of the cookie above. You can freeze the unglazed baked cookies for up to a month, then thaw and glaze fresh when you need a burst of nostalgia on short notice.
Quick Reference Before You Start
Having everything measured and ready before you begin makes this recipe flow smoothly from start to finish in under forty minutes. The dough is forgiving and easy to work with, which makes this a great project for cooking with kids or friends who claim they cannot bake.
- Pull your butter out early so it reaches true room temperature for the best creaming results.
- A cookie scoop makes portioning the dough fast and ensures even baking across the whole batch.
- Remember that the cookies will continue to set up as they cool, so pull them from the oven when the edges are just barely golden.
These cookies are a reminder that the best recipes are not always the most refined ones, sometimes they are just butter, sugar, and strawberry jam arranged with a little love and a lot of sprinkles.
Recipe FAQs
- → Can I use other jams instead of strawberry?
-
Yes. Raspberry, blueberry, or apricot jams work well—choose a thicker jam to reduce leakage during baking.
- → How do I stop the jam from leaking out?
-
Press edges firmly to seal and smooth the dough around the filling. Chill the assembled cookies briefly before baking and use slightly thicker jam to minimize seepage.
- → Can I make the dough ahead of time?
-
Absolutely. Refrigerate the dough for up to 48 hours or freeze portions for longer storage. Let chilled dough soften slightly before shaping.
- → How do I get a smooth glaze?
-
Whisk powdered sugar with a small amount of milk and vanilla until smooth and thick but pourable. Add liquid a teaspoon at a time to avoid thinning the glaze too much.
- → Will the cookies keep their texture after glazing?
-
Yes—allow cookies to cool completely before glazing and let the glaze set fully on a wire rack to keep the crisp edges and tender centers.
- → Any tips for decorating with sprinkles?
-
Apply sprinkles while the glaze is still wet so they adhere. Use nonpareils or jimmies and check labels if nut cross-contamination is a concern.
