These buttery sugar cookie rounds are filled with strawberry jam, baked until edges are lightly golden, then glazed and decorated with sprinkles. Dough comes together in one bowl; form balls with 1 tbsp, seal 1/2 tsp jam inside, bake 12 minutes at 350°F. Cool before glazing. Seal edges well to prevent leaks; try raspberry or a pinch of cinnamon for variation.
My sister dared me to make cookies that tasted like Saturday morning cartoons, and these strawberry jam filled beauties were the delicious result.
I brought a batch of these to a neighborhood potluck last summer and watched three adults completely ignore the fancy pie table just to grab seconds of these cookies.
Ingredients
- All purpose flour (2 1/2 cups or 315 g): The backbone of the cookie, giving it that tender sugar cookie texture that holds the jam without crumbling apart.
- Baking powder (1/2 teaspoon): Just enough lift to keep these soft without turning them into cakey little domes.
- Salt (1/2 teaspoon): Trust me on this, the salt makes the sweetness sing instead of becoming cloying.
- Unsalted butter, softened (1 cup or 225 g): Room temperature butter is non negotiable here because cold butter will leave you with lumpy dough and uneven cookies.
- Granulated sugar (3/4 cup or 150 g): Provides the classic sweetness and helps those edges turn a lovely pale gold.
- Packed light brown sugar (1/4 cup or 50 g): A small amount adds chew and a whisper of caramel that plain white sugar cannot manage alone.
- Large egg (1): Binds everything together and contributes to that rich, tender crumb.
- Vanilla extract (2 teaspoons): Use the good stuff if you have it because the vanilla flavor really comes through in such a simple dough.
- Strawberry jam (1/2 cup or 160 g): The star of the filling, so pick a jam you would happily eat on toast.
- Powdered sugar (1 cup or 120 g): The base of that iconic Pop Tart style glaze.
- Milk (2 tablespoons): Thins the glaze to the perfect drizzly consistency.
- Vanilla extract for glaze (1/2 teaspoon): Rounds out the sweetness of the glaze beautifully.
- Red or pink food coloring (optional): A drop or two gives the glaze that nostalgic pink frosting look.
- Rainbow sprinkles: Completely necessary for the full Pop Tart experience and they make people smile every single time.
Instructions
- Get your oven ready:
- Preheat to 350°F (175°C) and line two baking sheets with parchment paper so nothing sticks.
- Whisk the dry stuff:
- In a medium bowl, whisk together the flour, baking powder, and salt until evenly combined and set aside.
- 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 absolutely irresistible.
- Add the wet ingredients:
- Beat in the egg and vanilla extract until everything is smooth and well combined, scraping down the sides of the bowl as needed.
- Bring the dough together:
- Gradually add the dry ingredients to the wet mixture, mixing just until the dough comes together and no dry streaks remain.
- Stuff and seal each cookie:
- Scoop one tablespoon of dough and flatten it in your palm, place half a teaspoon of strawberry jam in the center, then top with another tablespoon of dough and pinch the edges shut 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 lightly golden.
- Cool completely:
- Let the cookies rest on the baking sheet for five minutes, then transfer to a wire rack to cool completely before glazing.
- Glaze and decorate:
- Whisk the powdered sugar, milk, vanilla, and food coloring if using until smooth, then spread over cooled cookies and shower with rainbow sprinkles before the glaze sets.
The afternoon my niece helped me make these, she ate so many sprinkles off the counter that she declared it the best cooking day of her entire life.
Jam Swaps and Flavor Twists
Raspberry jam makes a slightly tarter version that balances the sweet glaze beautifully, and blueberry jam turns them into a deep purple surprise that kids find magical. You could even try apricot preserves for something unexpected and sophisticated enough for adult palates.
What to Watch Out For
These cookies contain wheat, dairy, and egg, so be mindful when sharing with friends who have allergies. Check your sprinkles and jam labels carefully since some brands process near nuts and that cross contamination risk is real.
Storing Your Cookies
Keep them in an airtight container at room temperature and they stay wonderfully soft for up to five days. The glaze may soften over time but the cookies only get more tender and jammy as they sit.
- Freeze unglazed cookies for up to three months and thaw before decorating.
- Layer parchment between stacked cookies so the glaze does not smudge.
- Always add sprinkles immediately after glazing before the surface skins over.
These cookies are pure joy in pastry form, and sharing them with someone who needs a little sweetness is the best reason to make them.
Questions & Answers
- → How do I prevent jam from leaking during baking?
-
Seal the dough edges thoroughly by pinching and smoothing the seams; chill formed cookies on the sheet for 10 minutes before baking to help them hold shape. Use a small amount of jam (about 1/2 tsp) to reduce leakage.
- → Can I use a different jam?
-
Yes. Raspberry or blueberry work well; choose a thicker preserve or gently cook down a runnier jam to reduce moisture and keep fillings from oozing during bake time.
- → How do I get a smooth glaze?
-
Whisk powdered sugar with milk slowly until satin-smooth and slightly thick. Add liquid a teaspoon at a time to control consistency; thin glaze runs, thicker spreads and sets with a shiny finish.
- → What temperature and bake time should I use?
-
Bake at 350°F (175°C) for about 12 minutes, or until edges are just turning golden. Ovens vary, so watch the first batch and adjust by a minute or two as needed.
- → Can I make the dough ahead or freeze cookies?
-
You can chill dough for up to 48 hours or freeze unbaked sealed cookie balls for up to 3 months. Bake from frozen, adding a couple minutes to the bake time and watch for golden edges.
- → Any tips for decorating with sprinkles?
-
Apply sprinkles while the glaze is still wet so they adhere evenly. For even coverage, gently press a few sprinkles into the glaze rather than shaking them on from high above.
