In general, most people think of fresh cranberries for one thing and one thing only: cranberry sauce.
That’s not a “bad” thing! Cranberry sauce brings me back to my mother’s kitchen.
To this day she makes the best cranberry sauce for Thanksgiving. I don’t even need the turkey to eat it…just hand me a spoon!

However, there are so many other uses for this versatile fruit besides cranberry sauce and I am excited to share one of those ways with you – a fresh cranberry bar!
First off, let’s talk health benefits:
The fresh cranberries in these bars not only add a unique flavor and beautiful color, but also heaping amount of Vitamin C and fiber. Plus, cranberries are naturally low in sugar!
Additionally, cranberries offer whole body health benefits. Scientists are actually exploring how the bioactive compounds found in cranberries may positively affect glycemic response, prevent recurrent UTIs, support gut health, improve heart health and reduce inflammation.
Did I lose you yet?
I hope not!

To simplify: Cranberries may improve your glucose response if you have type 2 diabetes, the compounds found in cranberries may feed good bacteria to support your gut health, and cranberry consumption can help prevent reoccurring Urinary Tract Infections (UTIs). Woo!
Now that we know cranberries are beneficial to our health…how are cranberries grown?
Cranberries are grown on vines. (Yes – cranberries grow on vines, not in water! The cranberry bogs are only flooded to harvest the cranberries!)

Most cranberries are grown in Wisconsin, Massachusetts, New Jersey, Washington and Oregon!
Let’s chat about this recipe…
Fresh Cranberry Bars with Oat Crumble Topping…
- Easy-to-make
- Tart and sweet at the same time!
- Rich in fiber and vitamin C
- A easy fall dessert…or breakfast! No judgement here!
- Takes less than 45 minutes to make
- You probably have most of the ingredients in your pantry already
- It’s a new Holiday favorite in my house!
What if I don’t have coconut sugar?
- You can use granulated sugar – I just really love the flavor coconut sugar gives this dish!
Can I use oranges instead of lemon in the cranberry layer?
- Yes! If you don’t have lemons, oranges are a fantastic substitute for both the juice and zest!

Can I use dried cranberries?
- While dried cranberries are absolutely wonderful, this recipe works best with fresh cranberries.
I love that the crumble topping and crust to this cranberry bar recipe is the same recipe!
Makes life just that much easier! You enjoy as is, or with a scoop of vanilla bean ice cream. Perfect for Thanksgiving or Friendsgiving and a fun way to enjoy this Fall fruit!

Instructions
- Preheat oven to 350°F.In a large bowl, mix all of the crumble topping ingredients together. The melted butter will combine the dry ingredients into a crumble.Press half of this mixture into an oven safe 8×8 baking dish and bake for 15 minutes.
- Meanwhile, in a saucepan over medium heat – make the cranberry mixture! Add the cranberries, juice, zest and sugar to the sauce pan. The cranberries will begin to pop and cook down. You may need to add a little bit of water. Add a tablespoon at a time! Let this cook down until it looks like, well…cranberry sauce!
- Pour this on top of the crust layer, and then top with the remaining oat crumble. Bake again for 20 minutes. Let rest for 30 minutes before cutting into it. (Trust me, I know it’s hard!)

I’m allergic to oats any ideas to make them without the oats?
I am sorry I haven’t tested this recipe without the oats so I cannot advise. If you try something and it works well please let me know how it goes!
This was just what I was looking for! Even better than a version I used to make. I love the tangy gooey cranberry layer so much, I want to try to maybe do it a little thicker or do like 3/4 or the crumble part next time. So delicious! I’m saving this in my little handwritten recipe book where I keep only the best 🙂
Awww I am soo so glad!! Thank you so much 🙂
So much butter!! Are 12 tablespoons really necessary?
I haven’t recipe tested it with less so I am not sure. So sorry!
These look delicious! I’m wondering if I can replace the white flour with almond or oat flour?
Hi Sharon! Thank you so much! Unfortunately I have never recipe tested it with those flours, I’m so sorry!
Hi! Do you think this would work with artificial sugar, for diabetics? Also, do they freeze well? Thanks!
Hello! I have not personally tested the recipe that way but I would recommend a product such as Swerve as a replacement. xo, Tawnie
