Frosted Brown Sugar Cinnamon Pop Tart Bars.

Frosted Brown Sugar Pop Tart Bars: Homemade and delicious gooey cinnamon brown sugar is sandwiched between two layers of salted brown sugar shortbread cookie dough, baked until flaky, and finished with a sweet cinnamon maple icing. These easy-to-make pop-tart bars are sweet, salty, very gooey in the center, and heavy on the cinnamon. Finish with a sprinkle of salt for that classic “pop tart” look. Every sweet brown sugar cinnamon bar is so delicious. Some might even say they’re addictive!

I’ve wanted to make these ever since I made my Chocolate Fudge Pop Tart Bars back in March. I grew up eating pop tarts only on very rare occasions. My favorite was always a toasted chocolate pop tart, and my runner-up was always the brown sugar cinnamon pop tart. I remember them both being so good.

The funny thing is that a few months ago, someone actually sent me a box of brown sugar cinnamon pop tarts. They sat on the shelf until I decided to make these bars just last week. It was then that I decided to open a package and see what they looked like up close.

They didn’t smell like anything, and they looked so sad compared to the photo on the box. They needed a homemade upgrade. I can say with so much confidence that these homemade bars are so much better. You have to try these.

For starters, this is a brown sugar shortbread cookie, so it’s sweet, buttery, salty, and has a delicious base. It’s probably one of my favorite types of cookie.

And then there’s the special filling. Since we’re approaching fall, I couldn’t help but double the cinnamon and add a few spoonfuls of apple butter – it’s DELICIOUS!

For the icing, I used an old favorite, my cinnamon maple icing from everyone’s favorite apple cider doughnuts.

Here are the details

Step 1: make the shortbread dough

In a bowl, mix the flour, brown sugar, and cinnamon. Next, take the cold butter and shred it using a box grater, just like you’d do with cheese. Mix the butter into the flour, then beat in water until the dough holds onto the bowl.

It’s important to use a COLD and SALTED butter. Cold butter will give the dough flakiness and the salt makes it all come together. You have to bake with salted butter.

Step 2: press the dough out

Take the dough and divide it in half. Press half the dough down into a 9×9 inch square baking dish fitted with parchment paper.

Take the remaining dough and use a rolling pin to roll it out into a square that’s just larger than a 9×9 inch square. To help guide you, trace the outline of the 9×9-inch baking dish onto a sheet of parchment paper. Now roll the dough out on the parchment to just past the edges of the outline. Set this aside for a quick minute.

Step 3: the filling

Mix everything in a bowl.

Brown sugar, apple butter, cinnamon, melted butter, and a pinch of salt. These will all smell so scrumptious together.

Step 4: assemble

Spread the brown sugar mix over the dough in the baking dish. Now, invert the reserved sheet of dough over the filling, trimming as needed to fit the dough into the pan.

I like to chill the bars before baking them to ensure they bake up nicely. 15 minutes in the freezer is perfect!

Then bake, bake, bake!

Step 5: the icing

While the bars are cooling, make the frosting.

The frosting is a mix of powdered sugar, cinnamon, maple syrup, and vanilla—simple ingredients that, when combined, are so very delicious.

If you’d like a shiny, glossy finish to your pop tart bars, use a couple of teaspoons of meringue powder. Meringue powder will give your frosting shine. It helps it set up and dry nicely so that the frosting doesn’t smudge when touched. This step is completely optional, though; it’s certainly not required.

Frost the bars and let the frosting stiffen for a few minutes, then sprinkle with pretzel salt. It’s delish and adds a salty crunch with every bite. Again, this, too, is optional though.

Let the bars harden, or enjoy them right away—they’re so yummy! Each bar is flaky and extra gooey. Everyone loves these! They’re perfect for back-to-school and the fall season ahead.
