Ingredients

½ cup unsalted butter (room temperature)
1 cup granulated sugar
2 large eggs (room temperature)
1 teaspoon vanilla extract or vanilla bean paste
2 ½ cups + 2 tbsp all-purpose flour
½ teaspoon fine sea salt
½ teaspoon baking soda
2/3 cup strawberry preserves
1 cup powdered sugar
1 ½–2 tbsp whole milk
½ teaspoon vanilla extract
Rainbow sprinkles (for decorating)

Instructions

Step 1: Line a square 8×8 inch metal baking pan with parchment paper, allowing it to hang over all sides. Preheat the oven to 375°F (190°C).
Step 2: In a stand mixer bowl, cream the butter and sugar together for about 3 minutes until light and fluffy. Scrape down the bowl.
Step 3: Add the eggs and vanilla extract, mixing until just combined. Scrape down the bowl again.
Step 4: Stir in the flour, salt, and baking soda until the dough begins to come together.
Step 5: Chill the dough in the refrigerator for 20 minutes to make it easier to handle and spread.
Step 6: Press half of the chilled cookie dough evenly into the prepared pan (about 348 grams).
Step 7: Carefully lift this dough layer out of the pan using the parchment overhang and transfer it to a baking sheet. Place it in the freezer to chill while you prepare the rest.
Step 8: Replace the parchment paper in the pan, ensuring all sides are covered. Press the remaining dough evenly into the pan.
Step 9: Spread the strawberry preserves evenly over the dough layer in the pan.
Step 10: Remove the chilled dough layer from the freezer, peel off the parchment, and place it on top of the jam layer. Press gently to secure.
Step 11: Bake the bars in the oven for 25–28 minutes or until the top is golden brown.
Step 12: Allow the bars to cool completely on a wire rack.
Step 13: Use the parchment overhang to lift the bars out of the pan and flip them upside down so the bottom becomes the top.
Step 14: Whisk together the powdered sugar, milk, and vanilla extract until smooth to make the glaze.
Step 15: Pour the glaze over the bars and sprinkle with rainbow sprinkles.
Step 16: Let the bars sit at room temperature for 1–2 hours until the glaze sets, then cut into 15 bars and enjoy.

Tips & Variations

For a cleaner cut, chill the bars in the refrigerator before slicing.
Try swapping strawberry preserves for raspberry or apricot for a different fruit flavor.
If you prefer a thicker glaze, reduce the milk slightly or add more powdered sugar until desired consistency is reached.

Storage

Store the Poptart Cookie Bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to one week or freeze for up to 2 months. When ready to serve, thaw frozen bars at room temperature and refresh the glaze if needed.

FAQs

Can I use a different size pan?

An 8×8 inch pan is ideal for these bars to achieve the right thickness. Using a larger pan will result in thinner bars and shorter baking time, while a smaller pan may require longer baking. Adjust accordingly and watch for doneness.

Why do I need to chill the dough?

Chilling the dough firms it up, making it easier to press evenly into the pan and layer without sticking. It also helps prevent the bars from spreading too much during baking, resulting in a neater appearance.

Ingredients

Scale

Cookie Dough

½ cup unsalted butter (room temperature)
1 cup granulated sugar
2 large eggs (room temperature)
1 teaspoon vanilla extract or vanilla bean paste
2 ½ cups + 2 tbsp all-purpose flour
½ teaspoon fine sea salt
½ teaspoon baking soda

Filling and Topping

2/3 cup strawberry preserves
1 cup powdered sugar
1 ½–2 tablespoons whole milk
½ teaspoon vanilla extract
Rainbow sprinkles (for decorating)

Instructions

Prepare the Pan and Oven: Line an 8×8 inch square metal baking pan with parchment paper, making sure the paper hangs over all sides for easy removal. Preheat your oven to 375°F (190°C).
Cream Butter and Sugar: In a mixing bowl, cream together the unsalted butter and granulated sugar for about 3 minutes until the mixture is light and fluffy. Scrape down the sides of the bowl.
Add Eggs and Vanilla: Mix in the eggs and vanilla extract until just combined. Scrape down the bowl again to ensure even mixing.
Add Dry Ingredients: Sift together the all-purpose flour, fine sea salt, and baking soda, then add them to the wet ingredients. Mix until the dough starts to come together.
Chill the Dough: Cover the dough and refrigerate it for 20 minutes to firm up, which will make it easier to press into the pan.
Press First Layer: Press half of the chilled dough (approximately 348 g) evenly into the prepared baking pan to form the bottom layer.
Freeze First Layer: Lift the parchment paper with the dough from the pan and transfer it onto a baking sheet. Place it in the freezer to firm up while you prepare the next layer.
Prepare Second Layer: Replace the parchment paper strips in the pan to cover all sides again, then press the remaining half of the cookie dough evenly into the pan to create the base for the top layer.
Spread Filling: Evenly spread 2/3 cup of strawberry preserves over the cookie dough layer in the pan.
Top Layer Assembly: Remove the chilled first dough layer from the freezer. Peel away the parchment paper and place this dough layer over the jam to sandwich it.
Bake: Bake the assembled cookie bars in the preheated oven for 25 to 28 minutes or until the top is golden brown.
Cooling: Remove from the oven and let the bars cool completely on a wire rack.
Invert Bars: Using the parchment paper handles, lift the bars out of the pan and flip them upside down so the bottom becomes the top.
Prepare Icing: Whisk together powdered sugar, milk, and vanilla extract until smooth to make a vanilla glaze.
Ice and Decorate: Pour the glaze over the top of the bars and immediately sprinkle with rainbow sprinkles for decoration.
Set the Icing: Allow the bars to sit at room temperature for 1 to 2 hours so the icing can fully set.
Serve: Cut the bars into 15 equal pieces and enjoy this nostalgic and delicious treat!

Notes

Use a metal 8×8 inch baking pan lined with parchment paper to easily lift the bars out of the pan.
Measure flour carefully by spooning into the measuring cup and leveling off with a knife to avoid dense dough.
Chilling and freezing the dough layers help maintain structure and ease assembly.
The icing can be adjusted in thickness by adding more milk to thin or more powdered sugar to thicken as needed.
Store leftovers in an airtight container at room temperature for up to 3 days.
