These buttery sugar cookie rounds are filled with strawberry jam, sealed at the edges, and baked until the edges are lightly golden. Start by creaming butter with granulated and brown sugars, add egg and vanilla, then fold in flour mixed with baking powder and salt. After baking and cooling, whisk powdered sugar with milk and vanilla for a smooth glaze, tint if desired, spread atop cookies and finish with sprinkles.
My kitchen smelled like a childhood Saturday morning the moment I sandwiched strawberry jam between two rounds of buttery cookie dough. Pop Tarts were the one thing my grandmother never made from scratch, and honestly, that always felt like a challenge she was quietly issuing me from across the years. These cookies are my answer: soft, jammy, glazed, and utterly unapologetic about how much fun they are to eat.
My neighbor Clara stopped by unannounced the afternoon I was testing my third batch, and she ended up sitting on my kitchen floor eating four of them straight off the cooling rack. We laughed until we cried about the sprinkles stuck to her sweater, and now she texts me every Saturday asking if the cookies are ready.
Ingredients
- All-purpose flour (2 1/2 cups, 315 g): The backbone of the dough, and you really do want to spoon and level it rather than scooping directly from the bag.
- Baking powder (1/2 teaspoon): Just enough lift to keep these tender without puffing them into domes.
- Salt (1/2 teaspoon): Don't skip it, because salt makes butter taste more like itself.
- Unsalted butter, softened (1 cup, 225 g): Pull it out an hour ahead, and if you forget, cut it into cubes and wait fifteen minutes.
- Granulated sugar (3/4 cup, 150 g): Provides clean sweetness and helps the edges crisp just barely.
- Packed light brown sugar (1/4 cup, 50 g): A small amount that adds chew and a whisper of caramel depth.
- Large egg (1): Binds everything together and enriches the texture.
- Vanilla extract (2 teaspoons): Use the real stuff here since it is a flavor you will actually notice.
- Strawberry jam (1/2 cup, 160 g): A thick, quality jam makes all the difference, so avoid anything too runny.
- Powdered sugar (1 cup, 120 g): The base for that iconic frosted look on top.
- Milk (2 tablespoons): Thins the glaze to the perfect spreadable consistency.
- Vanilla extract for glaze (1/2 teaspoon): Rounds out the sweetness of the icing.
- Red or pink food coloring (optional): A tiny drop goes a long way toward that nostalgic Pop Tart aesthetic.
- Rainbow sprinkles: Nonpareils work beautifully but Jimmies are less likely to bleed into the glaze.
Instructions
- Get your oven ready:
- Preheat to 350 degrees F (175 degrees C) and line two baking sheets with parchment paper so nothing sticks.
- Whisk the dry ingredients:
- In a medium bowl, whisk the flour, baking powder, and salt together until evenly combined.
- Cream the butter and sugars:
- Beat the softened butter, granulated sugar, and brown sugar in a large bowl until the mixture looks pale, fluffy, and lighter than you think it needs to be.
- Add egg and vanilla:
- Drop in the egg and vanilla, then mix until just incorporated without overworking the dough.
- Bring the dough together:
- Gradually add the dry ingredients to the wet, mixing gently until a soft dough forms and no dry streaks remain.
- Stuff and shape the cookies:
- Scoop one tablespoon of dough, flatten it in your palm, add half a teaspoon of jam to the center, then top with another tablespoon of dough and seal the edges completely before gently rolling into a ball.
- Arrange and bake:
- Place the cookies two inches apart on the prepared sheets and bake for twelve minutes or until the edges are just barely golden.
- Cool completely:
- Let them rest on the baking sheet for five minutes, then move to a wire rack and wait until they are fully cool before glazing.
- Glaze and decorate:
- Whisk the powdered sugar, milk, vanilla, and food coloring until smooth and thick enough to coat the back of a spoon, then spread over each cookie and finish with a generous shower of sprinkles.
The moment I watched my own daughter lick glaze off her fingers and declare these better than the real thing, I knew this recipe had earned a permanent spot in our family binder.
Jam Swaps and Flavor Twists
Raspberry jam tastes slightly more grown up and pairs beautifully with a pinch of cinnamon folded into the dough. Blueberry jam gives a milder, almost pancake-like quality that kids gravitate toward instantly.
Storage and Make Ahead
These cookies keep beautifully in an airtight container at room temperature for up to four days, though the glaze may soften slightly. You can freeze the unbaked stuffed dough balls on a sheet pan, then transfer them to a bag and bake from frozen, adding two extra minutes to the timer.
Tools You Will Want Handy
Nothing fancy is required here, but a few things make the process smoother and less messy.
- A small cookie scoop keeps portioning consistent and your hands cleaner.
- Parchment paper is essential for preventing jam leaks from becoming permanent pan damage.
- A wire rack ensures the bottoms cool evenly and the glaze sets without sticking.
Make a batch this weekend and watch how quickly they disappear from the plate. These little cookies have a way of turning an ordinary afternoon into something worth remembering.
Recipe Q&A Section
- → How do I prevent jam from leaking during baking?
-
Seal the edges firmly by pressing the dough layers together and smoothing the seams with your fingers. Chill assembled cookies briefly before baking to help the dough set, and avoid overfilling—about 1/2 teaspoon of jam per cookie works well.
- → Can I swap the strawberry jam for other fillings?
-
Yes. Raspberry, blueberry, or apricot preserves make great alternatives. Firmer, thicker jams or preserves reduce the chance of spreading; if using runnier fillings, use slightly less and ensure a good edge seal.
- → What is the best way to shape and fill the cookies?
-
Scoop uniform tablespoons of dough, flatten one, add a small dollop of jam, then top with another flattened tablespoon and crimp edges to seal. Roll gently into a ball to ensure an even shape before baking.
- → How should I store these cookies?
-
Keep glazed cookies in an airtight container at room temperature for 2–3 days. If stacking, place parchment between layers to protect the glaze. Uniced cookies can be stored longer or frozen for future glazing.
- → Can I freeze the dough or baked cookies?
-
You can freeze shaped, unbaked cookies on a tray until firm, then transfer to a sealed container for up to 3 months; bake from frozen with an extra minute or two. Baked cookies freeze well; thaw at room temperature before glazing.
- → How do I get the glaze the right consistency?
-
Start with powdered sugar and add milk a teaspoon at a time until you reach a spreadable but not runny texture. The glaze should hold on the cookie without pooling; add a drop of food coloring if you want a pink hue.
