Poptart Cookie Bars Recipe
Introduction
These Poptart Cookie Bars combine the nostalgic flavors of your favorite toaster pastry into a fun, homemade treat. With a buttery cookie base, a sweet strawberry filling, and a glossy vanilla glaze topped with rainbow sprinkles, they’re perfect for a snack or dessert.

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 an 8×8 inch square 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, cream the butter and granulated sugar for about 3 minutes until light and fluffy. Scrape down the bowl.
- Step 3: Add the eggs and vanilla extract, mixing just until combined. Scrape down the bowl again.
- Step 4: Mix in the flour, salt, and baking soda until the dough starts to come together.
- Step 5: Chill the dough in the refrigerator for 20 minutes to firm up—it will be easier to spread.
- Step 6: Press half of the chilled dough evenly into the lined baking pan.
- Step 7: Carefully lift this layer out of the pan using the parchment overhang and place it on a baking sheet. Put it in the freezer while you prepare the next layer.
- Step 8: Ensure the pan is still lined with parchment on all sides, then press the remaining dough evenly into the bottom of 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 carefully on top of the jam layer. Press firmly to seal.
- Step 11: Bake the assembled bars in the oven for 25–28 minutes, or until the top is golden brown.
- Step 12: Let the bars cool completely on a wire rack.
- Step 13: Use the parchment overhang to lift the bars from 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 decorate with rainbow sprinkles.
- Step 16: Allow the icing to set at room temperature for 1–2 hours before cutting into 15 bars and serving.
Tips & Variations
- Pressing the chilled dough layer out of the pan and into the freezer before assembling makes it easier to handle without breaking.
- For a different flavor, substitute strawberry preserves with raspberry, apricot, or blueberry jam.
- If you prefer a sweeter glaze, add more powdered sugar a little at a time until desired consistency is reached.
- Use parchment paper strips hanging over the sides to easily lift the bars from the pan without breaking them.
Storage
Store the bars in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly and freeze for up to 2 months. Thaw at room temperature before serving. If the glaze softens after refrigeration or freezing, let the bars sit at room temperature to firm up again.

FAQs
Can I use a different size pan?
While an 8×8 inch pan is recommended for best thickness and balance, you can use a slightly larger pan but the bars will be thinner and may bake faster. Adjust baking time accordingly and keep an eye on the color.
Do I have to chill the dough twice?
Chilling the dough before pressing helps with spreading and prevents it from sticking. Freezing the first dough layer makes it easier to handle when assembling the bars. Skipping these steps may make the process messier and could affect the texture.

Instructions
- Prepare Pan and Oven: Line an 8×8 inch square metal baking pan with parchment paper hanging over all sides for easy removal. Preheat the oven to 375°F (190°C).
- Cream Butter and Sugar: In a stand mixer bowl, cream together the room temperature butter and granulated sugar for about 3 minutes until light and fluffy. Scrape down the sides of the bowl.

- Incorporate Dry Ingredients: Add the all-purpose flour, fine sea salt, and baking soda to the wet ingredients and mix until the dough starts to form.

- Press Half the Dough: Press half of the chilled dough (approximately 348 grams) evenly into the prepared baking pan.
- Freeze First Layer: Lift the parchment paper with the dough out of the pan and place it on a baking sheet, then freeze it to set aside while preparing the rest.

- Bake: Bake the assembled cookie bars for 25-28 minutes, or until the top is golden brown.
