The trend of pastry bars emerged as a way to simplify assembly—no precise folding required—while still delivering that beloved, portable pastry experience.

- 1 tsp salt
- 1 cup (226 g) unsalted butter, cold and cubed
- 1 large egg, lightly beaten
- 1 tsp pure vanilla extract
For the Filling
- 1½ cups (300 g) light brown sugar, packed
- 2 Tbsp ground cinnamon
- 2 Tbsp unsalted butter, melted
- 2 Tbsp all-purpose flour (to thicken)
For the Glaze
- 1 cup (120 g) powdered sugar
- 2–3 Tbsp milk or cream
- ½ tsp pure vanilla extract
- Optional coarse sugar or cinnamon for sprinkling

Tools & Equipment

9×13-inch baking pan
Mixing bowls (large and medium)
Stand mixer or hand mixer with paddle attachment
Rolling pin
Parchment paper
Offset spatula or bench scraper
Cooling rack

Step-by-Step Recipe Instructions

1. Prepare the Dough

In a large bowl, whisk together flour, sugar, and salt until combined.
Using a pastry cutter or mixer on low speed, cut in cold butter until mixture resembles coarse crumbs.
In a small bowl, whisk egg and vanilla; add to the flour mixture and mix just until dough clings together—avoid overmixing to keep flaky layers.
Divide dough into two equal portions, flatten into disks, wrap in plastic, and chill for at least 30 minutes.

2. Assemble the Bars

Preheat oven to 350 °F (175 °C). Line the baking pan with parchment, leaving an overhang for easy lifting.
Roll one dough disk between parchment sheets into a 9×13-inch rectangle; transfer to pan and press firmly into corners.
In a bowl, stir together brown sugar, cinnamon, melted butter, and flour until crumbly. Evenly sprinkle the filling over the dough layer.
Roll the second dough disk into the same dimensions; carefully drape over the filling. Use your fingers or a fork to seal the edges and patch any gaps.

3. Bake & Cool

Bake for 25–30 minutes, rotating halfway, until the top is golden brown and filling bubbles at the edges.
Remove from oven and let cool completely in pan on a rack—this prevents the filling from oozing out when slicing.

4. Glaze & Finish

Whisk powdered sugar, milk, and vanilla until smooth and pourable.
Use an offset spatula or a spoon to drizzle glaze over cooled bars.
Sprinkle optional coarse sugar or cinnamon on top for extra crunch and visual appeal.
Once glaze sets (about 15 minutes), lift bars via parchment overhang, place on cutting board, and slice into 12–16 bars.

Variations & Substitutions

Gluten-Free: Replace flour with a 1:1 gluten-free baking blend; add 1 tsp xanthan gum if blend lacks it.
Vegan: Swap butter for vegan margarine and use a flax “egg” (1 Tbsp ground flaxseed + 3 Tbsp water).
Flavor Twists:
- Maple Brown Sugar: Substitute brown sugar with pure maple sugar or add 2 Tbsp maple syrup.
- Apple Pie Spice: Use apple pie spice blend instead of plain cinnamon.
- Streusel Topping: Combine ½ cup flour, ¼ cup brown sugar, 3 Tbsp cold butter to sprinkle on top before baking.

Serving Suggestions & Pairings

Serve warm alongside:
- Freshly brewed coffee or cinnamon-spiced latte
- Creamy chai or hot chocolate
For a decadent twist:
- Top with a scoop of vanilla bean ice cream for a bar sundae
- Arrange on a brunch board with fresh berries and mini muffins

Storage & Make-Ahead

Room Temperature: Store in an airtight container for up to 3 days.
Refrigeration: Keeps up to 1 week; bring to room temperature before serving.
Freezing: Wrap individual bars in plastic and foil; freeze up to 3 months. Thaw overnight in fridge or 30 minutes at room temperature.

Frequently Asked Questions (FAQs)

1. Can I use dark brown sugar instead of light brown sugar?
Yes! Swapping in dark brown sugar will give your Brown Sugar Cinnamon Pop Tart Bars a deeper, more molasses-rich flavor. The texture and bake time remain the same—just pack the sugar firmly when measuring.

2. What’s the best way to roll out the dough evenly?
To ensure uniform thickness, roll your dough between two sheets of parchment paper. Rotate the dough 90° every few rolls and apply even pressure. This technique prevents sticking and helps you achieve perfectly sized sheets for your pan.

3. How do I prevent the filling from leaking out during baking?
Seal the edges well by pressing the top and bottom dough layers together with a fork or by pinching with your fingers. If needed, chill the assembled, unbaked bars for 10–15 minutes before putting them in the oven to help the dough hold its shape and reduce leakage.

4. Can I make these bars ahead of time for a party?
Absolutely! Bake and glaze the bars up to 24 hours in advance. Store them in an airtight container at room temperature. Slice and arrange on a platter just before serving to keep the glaze fresh and glossy.

5. How can I make a gluten-free version?
Replace the all-purpose flour with a 1:1 gluten-free baking blend. If the blend doesn’t include xanthan gum, add 1 teaspoon per batch. Chill the dough a bit longer if it feels extra sticky, and you’ll have delicious gluten-free pop tart bars that hold together beautifully.

There’s nothing quite like sinking your teeth into warm, Brown Sugar Cinnamon Pop Tart Bars fresh from your own oven.
