Inspired by brown sugar cinnamon pop tarts, this super buttery shortbread is baked with a layer of cinnamon sugar in the middle. It’s basically a grown up version of a brown sugar cinnamon pop tart with elevated flavors and a delicious soft and tender texture.
How to make buttery shortbread
Taking direct inspiration from my strawberry pop tart shortbread recipe, I used the exact same shortbread recipe because it’s just too good!
When developing the recipe for the shortbread, I was very drawn to Scottish shortbread. It’s typically more rich, dense, and thick compared to regular shortbread due to its high fat content. In other words, it’s just better.
So for this pop tart shortbread, I made sure to up the butter and bake these bars low and slow. By doing so, you’re left with a dense but buttery tender shortbread bar that just melts in your mouth.
Another ingredient I used to boost the richness of these bars is almond flour. By swapping out some of the regular flour with almond flour, I’ve decreased the absorbency of the dry ingredients. Almond flour does not absorb as much liquid as regular flour, so these bars are able to remain extra buttery but with a dense and closed texture.
Layered brown sugar cinnamon shortbread
The one and only tricky part of this recipe is sandwiching the brown sugar cinnamon between two layers of shortbread dough, especially because the dough is soft and sticky. It requires some slight arts and crafts, but works like a charm!
First, take a sheet of parchment paper and place it under your baking dish. Trace the outline of the dish onto the paper using a marker. Then flip over the sheet (to conceal the marker) and set it aside.
Then, spread half of the shortbread dough into a prepped square baking dish. Spread the brown sugar cinnamon on top and press into an even layer.
Scoop the remaining shortbread dough into the center of the paper square and spread it even to fill that entire square. It can be a bit tricky, so I recommend holding the paper opposite the side you are spreading to prevent the sheet from moving around.
Once smooth, quickly flip the sheet of wax paper overtop the second half of the dough inside the pan. Peel back the paper and voila! Your brown sugar shortbread is now sandwiched. Gently smooth out the edges and it’s ready to bake.
Brown sugar shortbread baking tips
- Properly measure the flour – I say this in every post, and for good reason. It’s the number one reason why most recipes fail, especially for cookie dough. If there’s too much flour, this shortbread will turn out dry and crumbly. If you can, measure the flour with a food scale. Otherwise, to ensure you use the exact amount needed, gently spoon the flour into your measuring cup and level if off with a flat edge. If you scoop directly into the flour container, it packs it down into the cup which could leave you with 1/4 cup or more of added flour.
- Softened butter – Before you start, make sure your butter is softened to room temperature. This will create a smooth shortbread dough that bakes into a delicious melt-in-your-mouth texture. Alternatively, you can pop the butter bars in the microwave and heat in 5 second intervals, turning the bars between each time. Be careful not to overdo it as you don’t want MELTED butter. Then, place just the butter in the mixing bowl and mix on high speed until smooth.
- Powdered sugar – This is the secret to a buttery shortbread. Powdered sugar blends seamlessly into the dough, creating a soft texture. I don’t recommend replacing this with any other sugar as the outcome will be very different.
- Mixing – After adding the flour, gently mix together the dough. Over mixing will create a tough shortbread.
Chilling brown sugar shortbread bars
Once the bars are baked, it’s VERY important to let them chill for at least 1 hour. If you dig in right away, they’ll fall apart and turn into a buttery mess.
It’s the same reason why you must let brownies cool before slicing. When chilled, the butter will solidify giving you a dense but soft texture. So if your shortbread come out of the oven looking TOO buttery, don’t worry. Chilling will completely set these bars.
How to store brown sugar cinnamon shortbread
Keep the shortbread in the refrigerator in an air tight container. It will keep for up to 5 days.

Description
My absolute favorite pop tart flavor reinvented in this delicious brown sugar shortbread! Buttery shortbread is baked with a layer of brown sugar cinnamon in the center. It smells just like a freshly toasted brown sugar cinnamon pop tart, but tastes ten times better!
Ingredients
Shortbread
- 1 1/2 cups (195g) all purpose flour
- 1 cup (100g) almond flour
- 1/2 tsp kosher salt
- 1 cup (220g) unsalted butter, room temp
- 1 1/2 cups (170g) powdered sugar
- 1 large egg
- 1 tsp vanilla extract or vanilla bean paste
Brown Sugar Cinnamon Filling
- 1 cup (205g) light brown sugar, packed
- 1 tbsp cinnamon
- 2 tbsp all purpose flour
- 2 tbsp unsalted butter, melted
- 1 tbsp pure maple syrup
Cinnamon Maple Icing
- 3/4 cup (75g) powdered sugar
- 1 tsp cinnamon
- 2 tbsp unsalted butter, melted and cooled
- 1 tbsp pure maple syrup
- 1–2 tbsp milk, room temp
- Flaky sea salt, for sprinkling (optional)
Instructions
Shortbread
- Preheat the oven to 325F and coat a square 8×8 dish with nonstick spray and line all 4 sides with parchment paper, allowing it to hang over the edges of the pan for easy release.
- Trace a square outline of the pan on a separate sheet of parchment paper and set aside.
- In a medium bowl, whisk together the salt, almond flour, and flour. Set aside.
- In a large mixing bowl, using a hand or stand mixer with the paddle attachment, mix together the butter and sugar. Start on a low speed then slowly work your way up to prevent the sugar from flying out of the bowl.
- Once smooth and fluffy, mix in the egg and vanilla.
- Switch to a rubber spatula, add in the dry ingredients and mix by hand until combined. The consistency should be similar to mashed potatoes.
- Scoop half of the dough into the prepared baking pan and spread it even. I recommend using a small offset spatula or the back of a spoon to get it as even as possible.
- With the other half of the dough, spread it onto the sheet of parchment paper that we outlined earlier. Spread it to fit the square as best as possible.
Brown Sugar Cinnamon Filling
- In bowl, combine all of the ingredients. It should resemble wet sand.
- Crumble and lightly press an even layer of the filling on top of the shortbread dough that’s inside the pan.
- Then carefully flip the parchment paper dough on top of the filling layer and peel back the paper. The dough my stick a bit, so use your offset spatula or a butter knife to scrape it away as you carefully peel the paper.
- Once all the paper is peeled back, the top layer of dough won’t be perfect so spread it as even as possible.
- Bake the shortbread for 40-45 minutes or until it’s evenly puffed and the edges are a light golden brown.
- Let the shortbread rest at room temperature for 30 minutes, then transfer to the refrigerator to chill uncovered for about an hour.
Cinnamon Maple Icing
- Once the bars have chilled, make the icing.
- Whisk together all of the ingredients, starting with just 1 tablespoon of milk.
- If the icing appears too thick, mix in the additional tablespoon.
- The icing will set up quickly, so spread it on top of the shortbread as soon as you’re done mixing it.
- Top with a light sprinkle of sea salt, slice, and enjoy!

‘scuse me while i just sit and eat the icing by the spoonful!! SO delicous!! I made them with gluten free flour (I used 1:1 and substituted coconut flour for the almond flour) and they are amazing!! Thanks so much for this delicious recipe!
Erin says
These are incredible! Thank you!
Marlo says
Holy crap! I have missed poptarts! This is amazing! I regularly bake and my husband said that this is his favorite recipe. Seriously, thank you for creating this!!
Emily says
These were absolutely insane. Brought them to a Super Bowl party and they were a huge hit. Will definitely make again and again!
MG says
These are sooo tasty! I only used 1T of milk for the icing but it still has not really set after an hour. Any suggestions for next time? Thank you!
Jenna says
It won’t fully set like a regular pop tart, but you can add a little bit of meringue powder which will help dry it out.
Kellie says
These are delicious. But wondering the nutritional information
Emily says
These came out amazing!! My dough was pretty sticky and tough to work with though – is this normal or should I have added more flour? I did use a kitchen scale to measure. I used Trader Joe’s All Purpose
Jenna says
Yes the dough will be more sticky than your typical shortbread dough!
Vee says
I doubled the salt (which I almost always do with baking recipes). Rolled the top layer of shortbread in between two pieces of parchment to get it uniform, and refrigerated while I was preparing the filling to firm it up a little before peeling off.
These were a bit too sweet for me when they were warm, but serving the next day got rave reviews and taste fabulous!!!
Julie says
This recipe has a lot of steps and halfway through the recipe I was regretting the decision to make them. Even my hubs said he hoped I wouldn’t just chuck it all. All I can say is holy cow, WHAT A PAYOFF! These are delicious! I probably could have baked mine another 2 minutes but overall they turned out really well. One tip I would suggest: because the batter is a bit sticky, after spreading your batter onto the parchment for the top layer put it in the fridge while you make and press on the filling layer. Just that few minutes of chill time allowed me to pop the batter right onto the filling layer in one solid piece and peel back the parchment with ease yet it’s still malleable enough to press down and smoosh into any corners or press dough over to any low spots. I cut them with my serrated bread knife for perfectly sharp, clean cuts. Really glad I didn’t give up. Make these today!
Theresa says
Hi! I’m so excited to try these. I made the cookie base tonight and I’m wondering if I need to ice them tonight or if I can wait until the morning? They smell AMAZING! Thanks 🙂
Jenna says
Yes you can ice them the next day!
Stephanie says
These look like my dream. Can you make them gluten-free?
Jenna says
I haven’t done this but some readers have with success! Swap the all purpose flour with gluten free baking flour.
Kali says
These look insanely delicious! Do you think I could make these dairy free? Subbing for
Jenna says
Yes you can try using plant based ingredients!
Maggie says
I never comment on recipes but I was the star at thanksgiving with these and I have been asked to make them 3 times since! I use dairy free butter and it works like a charm.
Kyla says
I just got done baking (and eating) this delicious treat. Thanks so much for sharing this recipe! 🤍
Cassie says
I’ve made this recipe 3 or 4 times. It is SUCH a beautiful recipe and a total crowd pleaser. I use an offset spatula to spread the layers & have never used the extra parchment and haven’t had an issue doing it that way. Make this & youll repeat it a thousand times. Love it!!
Michelle says
I want to make these but there’s a nut allergy in my house. Can I substitute ap flour for the almond flour?
Jenna says
Sub oat flour 🙂
