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.
When my batter came out on the thick side, I thought I had messed it up somewhere but OMG was I wrong! I doubled the recipe and made these as a Thanksgiving dessert and everybody absolutely loved them. My 8 yr old son said “I could eat 3 pans of these!” lol. They are rich, decedent, full of flavour and the icing is amazing! This recipe is definitely going into my “keeper” desserts. Thank you for sharing 🙂
thanks a lot its really helpfull
im gonna make this today
Yay! Let us know what you think once you’ve given these a try 🙂
These are absolutely phenomenal. just what i was looking for- moist and dense, not airy/cakey like pumpkin roll. I went heavy on the spices and added some allspice to really amp up the pumpkin spice flavors on the second batch (yes I made this twice so far haha) and am happy with the extra kick.
I went with the cream cheese frosting recipe you linked- one batch of that is perfect for a double batch of these pumpkin bars.
I was wondering if you could use a jellyroll pan?
It’s possible, but our team hasn’t tried that so I can’t say for sure about the timing. Let us know how it goes if you give it a try!
Could these be made gluten free?
Hi Sarah! We don’t test our recipes with gluten-free ingredients, so we can’t say for sure, but feel free to experiment and see if you can modify the recipe to work for you 🙂
I’d love to try making these. I know butter is always the best option but it’s SO expensive where I live 🙁 Would I get the same outcome if I used margarine?
Hi Charlotte! No, unfortunately, margarine won’t produce the same results because it’s not made the same way butter is. Margarine is essentially a blend of oils. Nothing quite produces the same flavor and texture that butter does. Of course, feel free to experiment and see if you can achieve something you’re happy with using margarine, but we really do recommend real butter. Happy baking!
One of the best recipes I’ve made!!! I doubled the recipe, and baked in a 13 by 9 pan. It only needed a couple extra minutes in the oven. I didn’t double the frosting, and it was the perfect amount for me. Delicious!
These are soooooo good! Recipe was so easy to follow, the bars are so moist but thick, and the frosting just makes it. Will DEFINITELY make these again!
Hi! Is it possible to make these as cupcakes? I’d like to make this for a bake sale, and cupcakes are just easier
Hi Kate! While we haven’t tried that, I don’t see why it wouldn’t be possible – but just keep in mind that these bars don’t have the consistency most cupcakes do. Cupcakes are typically fluffy and fairly soft – these bars are a little more sturdy and chewy. Alternatively, give these Pumpkin Cupcakes with Nutella Frosting at try. Let us know how it goes! Happy baking 🙂
How did I miss those?! I will try them! Thank you!!
Why do you need to use a metal pan?
Hi Patty! Tessa explains about the pan in the pink tip box, above the recipe – but more info on glass vs. metal pans here! Let us know what you think of these bars once you have given them a try! 🙂
Hi, asking due to anaphylactic allergy to egg (& gluten sensitive) could this be made with “No Egg” replacer & GF flour? I understand it will change things a little bit but that’s my constant challenge. I love anything pumpkin & cinnamon.
Hi Donna! We haven’t tested this recipe with substitutions, but you’re welcome to experiment! Please let us know how it goes if you give it a try. Good luck!
I made these for Thanksgiving. They were a huge hit! The only thing I changed was in the frosting, I used pumpkin pie spice.
