- Step 8: Replace the parchment strips in the pan and press the remaining dough evenly into the pan.
- Step 9: Spread the strawberry preserves evenly over the dough in the pan.
- Step 10: Remove the frozen first layer from the freezer, peel off the parchment, and carefully place it on top of the jam layer. Press firmly to secure.
- Step 11: Bake the bars 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 paper to lift the bars out of the pan and flip them upside down so the bottom becomes the top.
- Step 14: Whisk together powdered sugar, whole milk, and vanilla extract until smooth to make the glaze.
- Step 15: Pour the glaze evenly over the bars and decorate with rainbow sprinkles.
- Step 16: Allow the bars to sit at room temperature for 1–2 hours until the icing sets. Cut into 15 bars and enjoy.
Tips & Variations
- For precise flour measurement, spoon the flour into your measuring cup and level off with a knife to avoid dense cookie bars.
- Try swapping strawberry preserves with raspberry or apricot for a different fruity flavor.
- Chilling the dough helps prevent it from spreading too much during baking, ensuring clean layers.
- If you prefer a thicker glaze, add less milk, or for a thinner glaze, add more milk a teaspoon at a time.
Storage
Store the Poptart Cookie Bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week or freeze for up to 3 months. When ready to eat, bring to room temperature and refresh the glaze if needed.

FAQs
Can I use frozen preserves instead of fresh?
Frozen preserves work fine; just make sure they are fully thawed and not watery before spreading to avoid soggy bars.

- 1 ½ – 2 tablespoons whole milk
- ½ teaspoon vanilla extract

Instructions
- Prepare Pan and Oven: Line an 8×8 inch square metal baking pan with parchment paper, letting the edges hang over the sides for easy lifting later. Preheat the oven to 375°F (190°C).
- Cream Butter and Sugar: In a stand mixer, cream the room temperature butter and granulated sugar for about 3 minutes until the mixture is light and fluffy. Scrape down the bowl to ensure even mixing.

- Combine Dry Ingredients: Add the flour, sea salt, and baking soda, mixing until the dough just begins to come together.

- Press First Layer: Press half of the chilled cookie dough evenly into the prepared baking pan (about 348 grams).
- Freeze First Layer: Lift out the dough layer by grabbing the parchment paper edges and transfer it to a baking sheet. Place it in the freezer to firm up while preparing the next layer.

- Add Filling: Spread the strawberry preserves evenly over the cookie dough in the pan.

- Glaze and Decorate: Pour the glaze over the top of the bars and sprinkle with rainbow sprinkles.
- Set and Serve: Let the bars sit at room temperature for 1 to 2 hours until the icing sets. Then cut into 15 bars and enjoy.
Notes
- For best results, measure flour by spooning it into the measuring cup and leveling it off rather than scooping directly to avoid dense dough.
- Using parchment paper strips hanging over the pan edges helps to easily lift the bars out after baking.
- Chilling and freezing the dough layers helps maintain distinct layers and easier handling.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
- You can substitute strawberry preserves with any other jam or fruit preserves of your choice.
