Save to Pinterest These nostalgic dessert bars combine a soft, buttery sugar cookie base with sweet strawberry jam filling and a classic vanilla glaze. The crumbled cookie topping creates that beloved poptart texture while colorful sprinkles add festive flair. Perfect for bake sales, potlucks, or whenever you crave childhood comfort food. Simple enough for beginner bakers yet impressive enough for any occasion.
My college roommate used to keep a box of strawberry pop tarts in our tiny dorm kitchen, and every Friday night we'd share them while studying. These bars capture that same joyful, breakfast-for-dinner energy but with a homemade touch that makes people's eyes light up when they take their first bite.
Last summer I made these for my niece's birthday, and she declared them better than the fancy bakery cookies we'd ordered. The way the jam gets bubbling and hot in the oven creates these little pockets of fruit that burst when you bite into them.
Ingredients
- Unsalted butter: Room temperature butter creates the best texture and helps the sugar incorporate properly
- Granulated sugar: Cream this thoroughly with the butter for that signature cookie bar crunch
- Large eggs: Add these one at a time to prevent the mixture from separating
- Vanilla extract: Pure vanilla makes a noticeable difference in the final flavor
- All-purpose flour: Measure by weight if possible for consistent results every time
- Baking powder: This gives the bars just enough lift without making them cakey
- Salt: A half teaspoon balances all the sweetness perfectly
- Strawberry jam: Use a high-quality jam with real fruit pieces for the best texture
- Powdered sugar: Sift this before making your glaze to avoid any lumps
- Milk: Start with two tablespoons and add more to reach your desired consistency
- Sprinkles: Add these immediately after glazing so they stick properly
Instructions
- Get your oven ready:
- Preheat to 350°F and line a 9x13-inch pan with parchment paper, letting the edges hang over for easy removal later.
- Make the cookie dough:
- Cream the butter and sugar until fluffy, beat in eggs and vanilla, then gradually mix in the flour, baking powder, and salt until just combined.
- Layer it up:
- Press two-thirds of the dough into the pan bottom, spread jam evenly over it, then crumble the remaining dough on top and press gently.
- Bake to perfection:
- Bake 23 to 27 minutes until edges are golden and center is set, then cool completely in the pan before glazing.
- Finish with flair:
- Whisk powdered sugar, milk, and vanilla until smooth, drizzle over cooled bars, and top with sprinkles right away.
Save to Pinterest My neighbor asked for the recipe after I brought these over for a casual dinner, and now she makes them for every school event. There's something about that combination of buttery cookie and sweet jam that makes people feel instantly at home.
Jam Swapping
Raspberry works beautifully if you want something a bit more tart, while apricot creates this lovely subtle sweetness that pairs perfectly with the vanilla glaze.
Make Ahead Magic
You can bake these a day in advance and store them tightly covered at room temperature. Add the glaze and sprinkles a couple hours before serving for the freshest look.

Recipe Questions & Answers
- → Can I use different jam flavors?
-
Absolutely! Raspberry, blueberry, apricot, or mixed berry jam all work beautifully. Choose your favorite fruit preserve or try multiple flavors for variety.
- → How should I store these bars?
-
Store in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. The glaze may soften slightly at room temperature.
- → Can I make these gluten-free?
-
Yes! Substitute the all-purpose flour with a 1:1 gluten-free flour blend. The texture remains similar, though bars may be slightly more tender.
- → Why do I press only part of the dough?
-
Pressing two-thirds creates an even base layer. The remaining dough gets crumbled over the jam, creating that signature poptart-style textured topping that bakes golden and crisp.
- → Can I freeze these cookie bars?
-
Yes! Freeze undecorated bars for up to 3 months. Thaw completely before adding glaze and sprinkles. Already glazed bars can be frozen but sprinkles may bleed slightly.
