Did you think keto jelly without all the artificial stuff was impossible? I did too for a while, but then I got to thinking and testing out a few ideas I had for keto friendly jelly that’s actually made with real fruit and guess what? It WORKED! This sugar-free jelly recipe is made with just 3 simple ingredients and after the mixture chills in the refrigerator overnight, you’ll be topping all of your keto bread with it!

If you’re missing fruit on keto, then add blackberries to your list. They are one of the lower-sugar fruits and a great way to enjoy natural sweetness while keeping keto. Try my sugar-free frozen yogurt, blackberry cobbler, or even putting blackberries on keto yogurt for a sweet treat without the sugar crash.

And, it makes a perfect grape substitute for keto friendly jelly, since it happens to be the same color and the flavor isn’t too far off. (But see the ingredient section below for a way to make it taste even more like grape jelly!)

The key to the best sugar-free jelly? Besti Monk Fruit Allulose Blend! This keto sweetener tastes and acts just like sugar, and dissolves effortlessly, so it gives the jelly the sweet flavor you are used to without any of the cooling or aftertaste effects that are typical with many keto sweeteners. More importantly, it won’t crystallize when you store your jelly in the fridge.

I served the jelly over bread made from my favorite keto bread mix (shown in the photos), which is by far the closest texture to real bread that I’ve ever had or made.

Sugar-Free Jelly Ingredients

This keto friendly jelly is made with just 3 simple ingredients!

Blackberries – The star of this jelly! Blackberries give the keto friendly jelly great purple color as well as fruity flavor.
Besti Monk Fruit Allulose Blend – This keto sweetener acts just like real sugar, but doesn’t have the sugar and carbs that go along with it.
Gelatin – Use an unflavored gelatin. It will thicken the jelly, but not impart any flavor.
Grape extract (optional) – If you want a grape-flavored jelly, add in some grape extract. (It’s totally optional, but makes it tastes like classic grape jelly.)

How To Make Keto Jelly

This sugar-free jelly recipe is fairly simple to make, let me show you how:

Boil. Combine water and blackberries in a medium saucepan. Bring to a boil and stir and mash berries as they soften. Simmer.

Strain. Pour berry mixture into jelly or nut milk bag over a sieve and press with the back of a spoon or spatula to push the juice into the bowl. You should end up with about 2 cups juice. Add water to reach this amount if you don’t get enough.

TIP: If you want a little texture in your jelly, you can stir some of the strained pulp into the liquid – not all of it, just a tablespoon or two.

Bloom. Sprinkle gelatin over more water in a small bowl. Stir together and set aside to bloom – it will be very thick.

Dissolve. Heat juice and Besti in a small saucepan, and stir until sweetener is dissolved. Then, stir in gelatin until it dissolves.

TIP: Adjust sweetener to taste here. It will seem less sweet after it sets, so at this step, make it a little sweeter than you want.

Chill. Pour liquid into a jar and refrigerate for 5-6 hours, or overnight, until set.

Sugar-Free Jelly FAQs

Is sugar-free jelly keto?

Store bought sugar-free jelly is pretty rare to find, and even if you did, grapes are not keto friendly to begin with, even before you add sugar or sweeteners.

On the other hand, sugar-free jams are commmon. These would be considered dirty keto, as they are made with highly processed ingredients and artificial sweeteners, like sucralose.

This keto jelly recipe is made with Besti, which is a natural sweetener that is used just like sugar, blackberries, and gelatin. That’s it!

Does sugar-free jelly have carbs?

Yes, sugar-free jelly will always have some carbs from the fruit, and sometimes from pectin if that is used. This sugar-free jelly recipe is made with real fruit and uses gelatin to set, so it has just 2 grams of carbs per serving.

Can I use a different sweetener?

For keto friendly jelly to work, you need an allulose-based sweetener with no sugar alcohols (i.e. no erythritol). This will ensure that it dissolves smoothly and doesn’t crystallize after cooling.

I recommend Besti Monk Fruit Allulose Blend, but you can also use plain allulose. Both granulated and powdered versions of these will work just fine because they dissolve so easily, but with most keto sweeteners, that’s not the case. Check my keto sweetener conversion chart, but keep in mind that erythritol-based sugar alternatives won’t work well.

Can I make different flavors?

Yes! You can use raspberries, blueberries, or strawberries, but I haven’t tested them to confirm how much you’d need. As long as you use 2 cups of juice after straining, it should work fine.

Keto Jelly Recipe Storage Instructions

Store jelly in the refrigerator for 4-6 weeks. The allulose in Besti actually acts as a natural preservative, but you still need to refrigerate it.

How to Eat Carb Free Jelly

You may not need any ideas on how to enjoy this keto jelly substitute, but I’ll share a few just in case!

Toast – Simple, delicious, and you may have thought you could never have toast with jelly on keto! Try white keto bread, almond flour bread, coconut flour bread, fathead bagels, or my very own keto bread mix.
Sandwiches – Keto peanut butter and jelly is a classic, but you can also spread some over cream cheese for a sweet and creamy meal.
Desserts – Swirl into keto ice cream, brownies (trust me on this one!), or even a low carb vanilla shake.

Nut Milk Bag – Use this to strain the blackberry juice from the solids.
Glass Jars – Store your keto friendly jelly in these glass jars, it’s just like the real thing!

3/4 cup Water (divided into 1/2 cup and 1/4 cup) ▢
24 oz Blackberries (~5 cups) ▢
1 1/2 cup Besti Monk Fruit Allulose Blend (to taste, see instructions) ▢
5 tsp Unflavored gelatin powder ▢

Instructions

Tap on the times in the instructions below to start a kitchen timer while you cook.

Combine 1/2 cup water and blackberries in a medium saucepan. Bring to a boil, stirring and mashing as berries soften.
Reduce heat to medium-low. Simmer for 5 minutes.
Line a mesh sieve with a jelly bag or nut milk bag and place over a bowl. Pour the berry mixture over the sieve. Press with a spoon or spatula to push the juice into the bowl. You should get about 2 cups of juice (add water to reach this amount if you don't get enough).
Meanwhile, pour the remaining 1/4 cup water into a small bowl. Sprinkle the gelatin powder into the bowl. Stir together, then set aside to bloom for at least 5 minutes.
Pour juice into a small stainless saucepan over medium heat. Add Besti and stir to dissolve. Taste and adjust sweetener to taste if needed - keep in mind it will seem less sweet after it sets, so make the liquid a bit sweeter than you want.
Reduce heat to low. Stir in the bloomed gelatin and heat, stirring, for about 2 minutes, until gelatin dissolves.
Pour the liquid into a jar. Refrigerate for at least 5-6 hours, or overnight, until set. Stir with a butter knife or spreader.

I read the question from a year ago about canning this recipe. Has anyone since then tried it with success?

What is the shelf life of this recipe in the fridge? Probably eat it all before then but just in case.

I will try this soon.

This tastes great and turned out perfect. I doubled the recipe and only used about 2/3`s of the allulose because we prefer it less sweet. We use it over your keto almond flour pancakes.

    I want to double and maybe triple the recipe. When I use the scale adjuster it still states 1/2 cup and 1/4 cup water no matter how many berries I use. Also the ounces of berries change but it still calls for 5 cups. And how do I determine how much gelatin? I am not sure if the scale converter works correctly.

      Hi Deborah, You can’t go by what is in the parentheses, those are notes for the original recipe. The measurements change when you increase the servings so you need to use those numbers if you want to double/triple the recipe.

Hi! It’s me again, Gladys🇨🇦
Today, I became very brave and tried to prepare a breakfast jelly…without fruit!
My inspiration was turning CHINESE WHITE TEA into a jello dessert, yesterday. It was amazing. And that was born out of preparing bulletproof coffee and adding gelatine to that as a late night something, something. Coffee jello. I have been haunted by a childhood memory of my grandmother serving me her home made BLACKCURRANT jam on her very unique pancakes. It is the BLACKCURRANT flavour I miss and seek. Finally, something that tastes like the BLACKCURRANT I seek. A tea AHMED brand… pricey, but all the comments raved that the flavour is so good … the tea is worth every penny. I ordered a box of 20 bags. Yes, the tea is exquisite. It has taken me a few months to courageously ask for guidance from people like you! Your blackberry jam recipe nudged me to try today. To a coffee mug, I added 1/2 tbsp gelatine. I added 1/2 tsp NOW stevia powder…where 1/2 tsp stevia is = 1/2 cup sugar. I placed the fruity teabag in the cup and poured the boiling water over the bag. Stirred well and tasted a few drops of the hot tea. Plenty sweet as a cup of tea…but not for a spread for bread. So, I added another 1/4 tsp powdered stevia and stirred again. Plus 2 x 1/16 tsp BLACKCURRANT flavouring extract. And walked away for about 20 minutes. Returned and pulled out the teabag surrounded by thickening goo gel. And again tasted… delicious. And then placed the coffee mug in the fridge to really set. I just retrieved that mug. It smells divine. It tastes wonderful. It is set like Welch’s grape jelly. I love it…but being tough on myself, I think it could use 1/16 tsp more extract….so it really pops those taste buds on bread! And this is from a tea bag that includes added black tea. Let’s call it a caffeinated jelly. So, today, I ordered the WILD STRAWBERRY HERBAL TEA by AHMED and it is on its way from Amazon.ca. It is herbal, no tea added. I bet I can do the same and make a truly zero carb, no fruit jelly to enjoy on great PSMF keto bread, or toast. Now I wait for my new Amazon delivery. I am so proud of myself… did it and had to share!

  Gladys, how interesting! You’re very innovative. I have little food imagination and as such, I have no desire to experiment. Thanks for sharing your good results and detailed information about how to do it. I may be trying it. (For me, that’s close to a commitment.😉)

Is there a way of preparing jelly for toast without fruit…. Just fruit extract flavouring!
But sweet and thick like Welch’s Grape Jelly.
And can I sweeten it with NOW stevia powder which dissolves completely.
Here in Canada,🇨🇦Allulose is hard to find and over the top expensive.
I purchase NOW stevia powder by the pound and use it for most things.

  Hi Gladys, I’m not aware of a way to make this without fruit. Besti is available here, including in Canada — just select the Canadian flag at the top.

I tried this and mine came out like Jello – in other words, it doesn’t spread. I feel like I am bound to have done something wrong. Should I maybe reduce the amount of gelatin? By the way, the flavor was great!

  Hi Jim, Stir it with butter knife to help break up your jam. This should help you be able to spread it. Feel free to adjust the amount of gelatin if you prefer for the next batch.

  Hi can I use concord grapes in this recipe and after I seal in jars can I freeze this .Thanks in advance
  - Wholesome Yum M
    0 September 21, 2021Reply
    
    Hi Kim, Concord grapes are significantly higher in sugar than blackberries. Using grapes instead of blackberries would make the carbs too high to be a keto or low carb recipe. If carbs are not an issue, then the recipe would work using grapes. Keep in mind that you may need to adjust the amount of gelatin needed if your yield is more than 2 cups of liquid. Enjoy!
