How to Make Pumpkin Bars with Brown Sugar Frosting
Best Pan for Baking Pumpkin Bars
- I love this 8-inch square pan by USA Pan
- Feel free to double the recipe and use a 9 by 13-inch pan
- I don’t recommend baking these bars in a glass, ceramic, or silicone pan – learn why here!
- I also don’t recommend using a dark-colored pan. These types of pans heat too aggressively and can dry out these bars.
What Type of Pumpkin is Best for These Bars?
Make sure to use canned pumpkin puree, NOT pumpkin pie filling in these bars. Also be sure to check out my Fresh vs. Canned Pumpkin article for the differences between using fresh pumpkin puree, regular canned pumpkin, and organic canned pumpkin. Just take a look at the images below to see how different each variety look, even before baking!
Brown Sugar Frosting
- This brown sugar frosting retains a little crunch to it, which sets it apart from a typical buttercream using much finer powdered sugar.
- I personally love it, and the slight crunch almost reminds me of eating raw cookie dough!
- If that doesn’t appeal to you, feel free instead use a half batch of my Best Buttercream Recipe
- You can alternatively use a batch of my Cream Cheese Frosting recipe.
- Add 1/2 teaspoon ground cinnamon to either recipe, if desired.
How to Store Pumpkin Bars with Brown Sugar Frosting
Store Pumpkin Bars in an airtight container at room temperature for up to 1 day or in the fridge for up to 5 days.
Can you Freeze Pumpkin Bars with Brown Sugar Frosting?
We haven’t tried freezing these bars, but it should work just fine. For best results, freeze unfrosted. Allow the bars to cool completely, then store inside an airtight container for up to a month. Allowing it to defrost at room temperature before icing and serving.

Pumpkin Bars with Brown Sugar Frosting
Ingredients
For the bars:
- 1 1/2 cups (190 grams) all-purpose flour
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground ginger
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1 stick (113 grams) unsalted butter, melted
- 2/3 cup (133 grams) packed light brown sugar
- 1 large egg, at a cool room temperature
- 1 teaspoon vanilla extract
- 1 cup (212 grams) pumpkin puree
For the frosting:
- 1 stick (113 grams) unsalted butter, at room temperature
- 1/4 cup (50 grams) packed light brown sugar
- 1/2 teaspoon ground cinnamon
- 1/8 teaspoon salt
- 1 1/2 cups (188 grams) powdered sugar, sifted
- 1/2 teaspoon vanilla extract
- 1 tablespoon milk, plus more if needed
Instructions
To make the bars:
- Preheat the oven to 350°F. Line a 8 by 8-inch baking pan with foil or parchment paper, leaving an overhang.
- In a large bowl, combine the flour, cinnamon, ginger, nutmeg, baking soda and salt.
- In a separate medium bowl, whisk together the butter, brown sugar, egg, vanilla, and pumpkin. Add the butter mixture to the flour mixture, stirring until just combined. Pour the batter into the prepared pan.
- Bake for 25 minutes, or until a cake tester inserted into the center comes out clean. Be careful not to overbake. Set the pan on a wire rack to cool completely.
To make the frosting:
- In a large bowl, use an electric mixer to beat the butter and brown sugar on medium-high speed until light, fluffy, and smooth. Add in the cinnamon and salt. On low speed, gradually add in the powdered sugar until incorporated. Add in the vanilla and milk and increase the speed to medium-high. Beat until very light and fluffy. If the frosting becomes too runny, add more powdered sugar. If the frosting is too thick, add a splash more milk. Spread the frosting evenly all over the pumpkin bars.
- Cut into squares before serving. Store in an airtight container at room temperature for up to 1 day or in the fridge for up to 5 days.
Perfection! This is a great twist on a pumpkin bread! A little more dense, very moist, FULL of fresh flavor! The Brown Sugar frosting is DIVINE and it’s the first time I’ve successfully made a frosting – my tip? Do not rush it! Let your butter sit out (I let mine out for an hour) so it can be soft enough to make your end result light and fluffy! I whipped my butter/brown sugar for 6 or 7 minutes, took my time adding the powdered sugar, and then let it get really extra whippy at the end. It was more frosting than we like so I didn’t use it all but for those who like extra frosting, this recipe provides for that. ENJOY! (We devoured it before any pics could be taken for evidence!)
So happy you loved this recipe!
Wow! This was amazingly good. Dense and delicious. That frosting… Yummmy!
Hi there!
What adjustments would need to be made to bake these in a 9×13 cake pan? Or a 1/2 sheet pan?
Thank you!
Karin
Hi Karin! You would double the recipe completely to bake in a 9×13 pan and add a few minutes onto the baking time 🙂 We haven’t tried a 1/2 sheet pan with this recipe, but the common rule is to make 1.5x the amount. Doubling will result in an overflowed pan! Here’s a great article by King Arthur Baking that may help you in the future! CLICK HERE
I doubled the recipe and I’m glad I did because these are awesome!!! I found them to be easy to make. The frosting is SO GOOD!! Everybody loved them! Another perfect recipe. Thank you!!
Loved this recipe!! The bars were perfectly moist and spiced and the icing was so fluffy and the perfect sweetness to complement the bars 🙂 Definitely recommend as this was also so easy to make!
Yay! So glad you loved this recipe, thanks so much for letting us know!
Hi,
Everyone loved these bars but, when I made the brown sugar frosting it was crunchy. I looked online for suggestions about how to fix it and none of them worked, so I re-made the frosting but sifted the brown sugar before combining it with the butter, and made sure not to under beat it because of what happened the first time I made it. (I keep the brown sugar in a canning jar canister with a tightly sealed lid, so it wasn’t hard or dried out) Even after sifting there was still a little crunch to it, so I threw it out again and just made a buttercream. But I really would like to make that brown sugar frosting, what did I do wrong? Ultimately the bars were a HUGE hit, but I was disappointed about the whole frosting thing. (And, call me crazy but, I’m going to try buying a fresh box of brown sugar and remaking it a third time because I REALLY want to make that frosting work! Haha!) Thanks for the recipe and any tips you may be able to send my way.
Hi Sil! This brown sugar frosting is just not as smooth by its nature as a powdered sugar frosting. We think of it as being a bit like cookie dough! You could try using a different brand of sugar or even a different buttercream if you don’t care for the texture of brown sugar. Here’s a link to our Best Ever Buttercream recipe — vanilla, cinnamon, or even maple buttercream would be absolutely delicious with these bars. I hope that helps!
If the brown sugar is too gritty for your likes, I would just make a cream cheese frosting instead!
Delicious, made for neighbors party and everyone loved them
Can these bars be made with almond flour vs all purpose flour. The sound and look awesome
Hi Linda! We haven’t tried that, we don’t use almond flour in our recipes. Good luck!
Hi Emily! Thank you for a wonderful recipe! It was just the right spicy mix and the lighter frosting really complemented the moist pumpkin bars. Everyone loved it!!!
Aw yay!! So happy to hear that, thanks so much for sharing! 🙂
Amazing recipe! The pumpkin bars are a hit with my family. Easy recipe to whip up for everyone to enjoy. HTH knocked this one out of the park.
Hooray!! So happy to hear they were such a hit!! Thanks so much for sharing! 🙂
Hi, I have been dying to make these bars! I have a fresh jar of McCormick pumpkin spice. How can I substitute that for the spices you have listed? Thank you so much!
We haven’t tried that, so I can’t say for sure! Your best bet is to substitute in an equal amount of pumpkin spice for the individual spices, then add more to taste. Keep in mind that the end result won’t taste quite the same though as pumpkin pie spice is only about half cinnamon. Please let us know how it goes if you give it a try!
Hi- my friend made these bars and gave me the recipe so can’t wait to bake them this weekend – they were heavenly!
One question – for the frosting – do I sift the powdered sugar before measuring? Or just sift it after measuring?
thanks –
Hi Eve! Excited for you to enjoy them! You will measure the powdered sugar, then sift. Just for future reference, anything listed after a comma for an ingredient will be done after measuring the ingredient. So if the ingredient is listed instead as “1 1/2 cups sifted powdered sugar”, then you would sift prior to measuring. I hope that makes sense!
