3 Ingredient No Bake Pumpkin Bars (Keto, Low Carb)

Super moist pumpkin cake bars topped with frosting that don’t require any cooking or baking. These pumpkin bars are just three ingredients and so easy to make. They are also a keto-friendly and low carb dessert.

These bars took me about 10 minutes to make and then into the fridge they went to set. Not only are they easy to make but they are also healthier than traditional pumpkin bars.


  • Pumpkin Puree
  • Powdered Erythritol
  • Coconut Flour

These three ingredients are all you need to make the pumpkin bars. If you want the bars to taste more like pumpkin pie, I highly recommend adding pumpkin pie spice.


These cake bars taste like a very moist cake. The texture is similar to the inside of a cake pop. Cake pops are usually made by mashing together cake with frosting, creating a very moist cake ball. That is what these pumpkin bars are like, especially when you eat them with the frosting.

Frosting Options

Pumpkin bars are usually topped with cream cheese frosting. And you can definitely do that for these. But cream cheese frosting does require a little bit of work and I didn’t want a frosting that was more work than the pumpkin bars.

So I topped mine with a very easy 2-ingredient frosting that takes about two minutes to make. You can add a little cinnamon or pumpkins spice to it as well but I wanted the frosting to stay white in color so I didn’t add any spice.

  • 8 oz pumpkin puree
  • 4 tbsp powdered erythritol
  • 1/2 cup coconut flour
  • pumpkin pie spice optional, see notes


  • 1/2 cup powdered erythritol
  • 1/4 cup heavy cream see notes for substitutions
  • water as needed to thin out frosting


  • Line an 8 inch by 4 inch loaf pan with parchment paper.
  • In a large bowl, add pumpkin and powdered erythritol. Mix until evenly and completely combined. Taste and add more sweetener if desired. If using pumpkin pie spice, add it at this time also.
  • Stir in cocout flour until your batter becomes very thick, like a very moist cake. You may need a little more coconut flour to reach your desired consistency. Spread batter into prepared pan, pressing down to compact the batter.
  • To make the frosting, add powdered erythritol and heavy cream to a small bowl and whisk until evenly combined. Add a little water at a time until frosting reaches desired thickness.
  • Spread frosting across surface of pumpkin bars. Place loaf pan into the fridge for about 1 hour or until pumpkin bars firm up enough to slice.
  • Slice pumpkin bars with a sharp knife. Store any uneaten bars in the fridge.


  • If you want the bars to taste like pure pumpkin, then don't add any spice. If you want them to taste like pumpkin pie bars, add 1/2-1 tsp of pumpkin pie spice or a blend of cinnamon, nutmeg, ground cloves and ground ginger.
  • I made a very basic white frosting for these bars. If you want to add more flavor to the frosting you can add a splash of vanilla or a dash of pumpkin pie spice or cinnamon.
  • You can make the frosting with milk (soy, almond, coconut, or oat milk will also work) instead of heavy cream but I prefer the heavy cream as it makes the icing tastes richer and it makes it thicker. If you are using milk you will need less of it, so I recommend adding it in 1 tbsp at a time and mixing in between.
  • Pumpkin bars are often served with cream cheese icing. If you prefer cream cheese icing, I have a low carb cream cheese icing recipe here.
  • You must use powdered erythritol for the bars and the frosting. Granular sweetener will not melt into the pumpkin bars. I used Anthony's Confectioner's powdered erythritol*

  1. Oh my! This is so delicious! I’m not brave enough to try substitutions, but there was no need! Thank you so much for sharing such a fabulous dessert! ?

  2. LOVE these!!! The consistency is perfect and they taste just like pumpkin pie and not too sweet. Paired it with a keto cream cheese frosting and even my non keto family members loved it!! Will be making these for thanksgiving for sure. Thanks for this recipe!!

  3. Could you substitute stevia? These look yummy!

  4. Has anyone tried freezing the bars? Do they defrost well?

  5. I tried the recipe, but unfortunately it turned out more like a pumpkin pudding. It simply would not set. I wound up having to bake it and it took over an hour in the oven to set. Not sure if the amount of flour just wasn’t enough or the lack of eggs. Have you had this result with your recipe? If so, what did you do?

    • You need to make sure you add enough coconut flour so that the batter is already quite thick before you put it into the fridge. Depending on the brand of coconut flour, you may need to add a little more as I state in the recipe.

  6. Can I use almond flour

  7. If I do not have an 8×4 loaf pan handy, would it be okay to use an 8×8? I have everything else besides the loaf pan haha. 

  8. If you love pumpkin pie, it will be hard not to eat the whole pan!

  9. Can I substitute stevia?

  10. Waiting for daylight to get up and try it. I don’t have powdered but will put erythritol granulated in the coffee grinder. I will order powdered from your site. Will make these when it’s daylight. Thanks for the recipe. Love pumpkin. Looking forward to more. Thanks

  11. Is the powdered Erythritol the same consistency as powdered sugar (like on a powdered donut)? Do you think Splenda (sucralose) would work? I’ve found it blends in nicely with fruit and desserts. 

    • Yes powdered erythritol is the same consistency as powdered sugar. I don’t know if Splenda will work. If it will dissolve into the puree without needing heat or cooking then it should be fine.

  12. can almond flower be swapped for coconut? 

  13. That erythitol is elusive and hard to find. Whats a good sub? 

    • if you’re not on keto you can use powdered sugar. erythritol is not too hard to find. Swerve brand is sold at many grocery stores and other brands are available on Amazon

  14. Allergic to coconut, any suggestions for a suitable substitute?

    • Sorry I don’t have one at this time

    • I think the ratio of coconut flour to almond flour is 1/4 C to 1 C. Coconut flour absorbs more than almond, but if you can use almond flour, just mix it in slowly until you get the consistency that feels about right.

      • That is generally the rule though it will vary depending on the recipe. I think the issue is that you would need so much almond flour in this recipe that it wouldn’t taste right.

  15. On the three ingredient pumpkin bars, can I use almond flour instead of coconut flour?

  16. This looks and sounds delicious, I cannot wait to try it! Thank you for the recipe :)!

  17. Powdered erythritol. Yup, there’s always that one crazy ingredient not in the pantry… And it’s not currently available on Amazon…

    • the one I linked to may not be available but there are many other brands of it available on Amazon. You can also find it at Whole Foods. And if you have granular erythritol you can turn it into powdered using a food processor or a blender

    • I use the Swerve brand erythritol & have been able to purchase from Amazon.

  18. I used sweet potato and cinnamon and vanilla extract instead of pumpkin pure’ and pumpkin spice. Wonderful results. I hate pumpkin and pumpkin pie spices.

  19. I’m not so sure if we have this in our place. Any suggested alternative for erythritol powder? Frankly, I havn’t tried cooking any recipe you forwarded to me, I’m so sorry. Anyways, many many thanks to what your sent. Good day.

  20. 11g carbs, 1g fat is the exact opposite of keto

    • There are 3 net carbs per bar. And while the recipe is low fat, this is meant to be a dessert, not a meal. You should be using actual meals to get the needed fat. I labeled this dessert keto-friendly because most people on a keto diet should be able to eat it without going over their carb count.

    • Making a cream cheese frosting would add fat and get it closer to a better keto ratio also.
