Introduction
Poptart Cookie Bars are a delightful twist on the classic breakfast treat, combining buttery cookie layers with a sweet strawberry jam filling. Topped with a smooth glaze and colorful sprinkles, these bars are perfect for snacks, desserts, or even breakfast on the go.

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 tablespoons 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 the paper to hang over all sides. Preheat your oven to 375°F (190°C).
- Step 2: In a stand mixer, cream the butter and sugar together for about 3 minutes until the mixture is light and fluffy. Scrape down the sides of the bowl.
- Step 3: Add the eggs and vanilla extract to the bowl and mix 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 firm it up, which will make spreading easier.
- Step 6: Press half of the chilled cookie dough evenly into the prepared pan.
- Step 7: Lift the first dough layer out of the pan using the parchment paper and transfer it to a baking sheet. Place it in the freezer to keep firm.
- Step 8: Replace the parchment paper in the pan to cover all sides again. Press the remaining half of the dough evenly into the pan.
- Step 9: Spread the strawberry preserves evenly over the dough in the pan.
- Step 10: Remove the chilled first dough layer from the freezer, peel off the parchment, and carefully place it on top of the jam layer. Press gently to secure.
- Step 11: Bake the assembled cookie 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 edges to lift the bars out of the pan, then 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 top of the bars and sprinkle with rainbow sprinkles.
- Step 16: Allow the bars to sit at room temperature for 1–2 hours until the icing sets, then cut into 15 bars and enjoy.
Tips & Variations
- For a different flavor, swap strawberry preserves with raspberry or apricot jam.
- Make sure the butter and eggs are at room temperature to help the dough come together smoothly.
- Use parchment paper with a good overhang to easily lift the bars out of the pan without breaking.
- If you prefer a thicker glaze, reduce the milk slightly.
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. Reheat briefly in the microwave to soften before serving if desired.

FAQs
Can I use frozen jam for this recipe?
Yes, frozen jam that has been thawed works fine. Just ensure it’s not too watery, as excess liquid can affect the dough’s texture.
Can I make these bars gluten-free?
You can substitute the all-purpose flour with a gluten-free flour blend suitable for baking, but results may vary depending on the brand. Adding a binding agent like xanthan gum might help maintain the texture.

Ingredients
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 tbsp 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 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 the room temperature butter and granulated sugar together for 3 minutes until the mixture becomes light and fluffy. Scrape down the sides of the bowl to ensure even mixing.
- Add Eggs and Vanilla: Mix in the eggs and vanilla extract just until combined, being careful not to overmix. Scrape down the bowl once more.
- Incorporate Dry Ingredients: Add the flour, salt, and baking soda to the wet ingredients. Mix until the dough just begins to come together.
- Chill the Dough: Refrigerate the dough for 20 minutes to firm it up, which will make it easier to spread into the pan.
- Press First Layer: Press half of the chilled cookie dough evenly into the lined baking pan—approximately 348 grams.
- Freeze the First Layer: Carefully lift the first dough layer out using the parchment paper and place it on a baking sheet. Freeze this layer to keep it firm while you prepare the rest.
- Prepare the Pan Again: Replace the parchment paper strips in the pan to maintain coverage on all sides.
- Add Second Dough Layer: Press the remaining half of the cookie dough evenly into the pan.
- Spread Strawberry Filling: Evenly spread the 2/3 cup of strawberry preserves over the top of the cookie dough in the pan.
- Add the Frozen First Layer: Remove the frozen dough layer from the freezer, peel off the parchment, and carefully place and press it over the strawberry preserves, securing it firmly.
- Bake: Place the pan in the preheated oven and bake for 25-28 minutes, or until the top is a golden brown color.
- Cool: Remove from the oven and allow the cookie bars to cool completely on a wire rack.
- Remove from Pan and Flip: Use the parchment paper overhang to lift the bars from the pan. Flip them upside down so the original bottom becomes the top.
- Make the Icing: Whisk together powdered sugar, milk, and vanilla extract until smooth to create the glaze.
- Glaze and Decorate: Pour the glaze over the top of the bars and sprinkle with rainbow sprinkles for a fun, colorful finish.
- Set and Serve: Let the bars sit at room temperature for 1-2 hours until the icing is set. Cut into 15 bars and enjoy!
Notes
- For accurate flour measurement, spoon the flour into your measuring cup and level it off with a knife to avoid packing.
- Using an 8×8 inch metal pan provides even heat for proper baking; glass pans may alter baking time.
- Chilling the dough helps to handle it easily and maintain its shape.
- Freezing the first dough layer before assembling helps prevent the layers from mixing during baking.
- Ensure eggs and butter are at room temperature for smooth blending and better dough texture.
