Did someone say sugar free fudge? Wait, hang on. Did someone say keto rocky road fudge? Those words are music to my ears and I bet they are to yours too.
Ever since I perfected my recipe for sugar-free marshmallows, I’ve been dying to try it in some rocky road fudge. Because who doesn’t love their fudge filled with lots of extras like sweet tender marshmallows and pecans?
I made this creamy no-bake treat recently for a party and it disappeared so fast. I swear I turned around for a few moments and when I turned back, it was all gone. So I came home and made it again the very next day!

Why you will love this recipe
I love when I can re-vamp a recipe to simplify it and make it even better. And that’s what I did with this sugar free fudge. In the original recipe, I had you make a batch of sugar free condensed milk. But I realized that this was an unnecessary step.
Now you simply simmer the cream for a few minutes before whisking in the rest of the ingredients. The whole process takes only about 15 minutes!
You do still have to wait for this sugar free fudge to set in the fridge for 3 hours. I know, I know, it’s hard to have patience. But you do get to lick the spoon while you wait. And if you happen to leave a little bit of the mixture behind in the saucepan, no one can blame you.
I simplified them even further by using ChocZero marshmallows. But you can use my homemade version too!
Ingredients you need
- Heavy cream: Sugar free fudge uses heavy whipping cream to melt the chocolate. You can use coconut milk for dairy-free.
- Sweetener: I use a combination of Swerve Confectioners and allulose because it provides the best consistency with no recrystallization. See the Expert Tips section for more information on sweeteners.
- Unsweetened chocolate: This is 100% cacao chocolate with no sweetener whatsoever. Don’t use sugar-free chocolate, it won’t set properly.
- Cocoa powder: A little additional cocoa powder helps thicken the mixture.
- Collagen: Chocolate collagen powder provides nutrition but it also gives the fudge a chewier texture.
- Marshmallows: You can use store-bought keto marshmallows or make your own. If you use your own homemade, freeze them for a few hours before stirring them into the fudge, so they don’t melt away.
- Pecans: I recommend toasting the pecans lightly for added flavor. You can use other nuts if you prefer.
- Pantry staples: Vanilla extract and salt.
Step by Step Directions
1. In a large saucepan, whisk together the heavy cream and the sweeteners. Bring to a simmer, whisking occasionally.
2. Remove from heat and add the chopped chocolate. Let sit a few minutes to melt, then whisk in the cocoa powder, collagen, vanilla extract, and salt until the mixture is smooth.
3. Add the marshmallows and pecans and stir to coat. Spread the mixture in a 9×9 inch pan lined with parchment paper.
4. Refrigerate until firm, about 3 hours. Then remove the fudge by the edges of the parchment and cut into squares.
Expert Tips
If you use homemade keto marshmallows, you will want about half the recipe. Chop them into 1/2 inch pieces and freeze for a few hours before stirring them into the fudge. This way, they won’t melt with the warm chocolate mixture.
Unsweetened chocolate helps the sugar-free fudge set properly. If you choose to use a keto chocolate like Lily’s or ChocZero, you may have to add more cocoa powder to help it set. I recommend an additional tablespoon.
Collagen also helps the fudge set and provides a creamy, chewy texture. If you don’t have chocolate collagen, use plain and add an additional tablespoon of cocoa powder as well as a little more sweetener.
Other protein powders may work too but they don’t always dissolve as well in the mixture.
A combination of sweeteners like erythritol and allulose works best for this rocky road fudge. Erythritol has a tendency to recrystallize and make the fudge gritty, but allulose can make the fudge too soft. In combination, they offset each other and provide the proper texture. You can try other sweeteners but just know that your results may not be ideal.
Frequently Asked Questions
This Rocky Road Fudge has very few carbs compared to conventional recipes. A small piece of regular chocolate fudge can have upwards of 25g of carbs. But this keto sugar free fudge has only 6.6g of carbs and 3.5g of fiber. So it has 3.1g net carbs per serving.
Keto fudge can be grainy when it’s made only with erythritol-based sweeteners, as it recrystallizes as it cools. A combination of erythritol with another sweetener like allulose or BochaSweet will prevent the recrystallization.
Store this fudge in the fridge in a covered container for up to a week.

I cannot wait to try this!!
Should the Allulose of Bocha-Sweet be powdered, too?
No, it doesn’t need to be. It dissolves better than erythritol.
Hi Carolyn I made this today … it’s been in the fridge for 6 hours and I noticed the chocolate fudge is setting quite soft still. Is the end product supposed to be firmer/denser? I did follow your recipe exactly w/o any substitution. Please let me know. Thanks!
It’s supposed to be firm like fudge. Can you tell me more? What brand of chocolate and sweetener?
Not sure if I did anything wrong but I was very rubbery…it didn’t taste or feel like rocky road or even look like the picture. I followed the recipe to a t, (I did use Allulose instead of Bocha Sweet) so not sure what happened. Was really looking forward to this! Any advice? Also hubby mentioned it had no sweetness to it.
So the “rubberiness” comes from the allulose, I think. I’ve had trouble with it in dense chocolate recipes as well.
Hi. I enjoy all your recipes and just received your Keto baking cookbook. I’m reading your Rocky Road Fudge recipe. In your notes you speak about the condensed milk. It’s not listed in the RRF recipe. Is it to be omitted?
Thank you.
No, it’s not being omitted. Because you need more of it, it’s built right into this recipe with the cream and sweeteners.
Do you remember the squares that look like this but were with peanut butter? They were at every church event and always on Christmas cookie platters. Sometimes with coconut on the outside. I don’t suppose you have a recipe for those? Or would consider creating one! (-;
Were they peanut butter and cornflakes? I remember making those as a kid.
OMG!! Finally, someone has mastered fudge. This is absolutely delicious! I had a hard time with my gas stovetop regulating the simmer. I watched the whole time, constantly raising and lowering the temp. I also had to use 95% chocolate bars from Ghiradelli, but they worked out fine. I realize the sugar is a bit higher. I am so in my happy place. I too, can have a delicious treat. You are the best!!
It seems as though the butter is just kind of sitting on top of the fudge once I spread it in the pan. What did I do wrong?
Your chocolate split, which means it needed less heat. If you notice it doing that before you add the marshmallows and pecans, there’s an easy fix. Just pop it in a blender.
For now, you can scrape off the butter once it’s chilled.
Thank you!
This fudge is outstanding!! My husband is a huge fudge fan and even in years past only got it at Christmas. He had really missed it since going full keto about 2 years ago. I made your recipe exactly as written and it turned out so well! It was a birthday surprise for hubby and he was shocked to know it wasn’t a cheat at all and completely sugar free. Thank you so much!!! Chocolatey, fudgy, and absolutely delicious. ❤️
Happy birthday do your husband!
I made this for Christmas this year and it was a complete winner! The marshmallows I made a couple days before and they were really easy as Carolyn says. I only froze mine for about 30 minutes and they were fine – no melting or gooping problems. Some my butter did not get completely beat into the fudge but pretty sure this was from me not whisking long enough. I used walnuts and they were very good! May not wait til Christmas to make this again! It was just excellent!
I’m trying this for the first time and starting with making the marshmallows. I couldn’t find grassfed gelatin at the store, so I got unflavored gelatin. Fingers crossed that it works!
It should!
My Mom used to make something similar to this only it had peanut butter in it too. It was so good. Unfortunately she is no longer with us. Since we are from Canada and you seem to know all the great Canadian treats, I was wondering if you know the treat I am talking about and if you have something similar?
I don’t know that one specifically but here’s a recipe that might help you: https://alldayidreamaboutfood.com/keto-chocolate-peanut-butter-fudge/
I wimped out and bought sugar free marshmellows. They are pretty firm on their own so would I still need to freeze or could I just fold them in like you would for regular marshmellows ? Thank and Regards
I haven’t ever used them but if you think it’s good, I’d go with it.
Can I use sugar free chocolate chips instead of cocoa? If so would I just subtract sugars?
No, you don’t use cocoa or sugar-free chocolate, you use only unsweetened chocolate. Changing it would affect the consistency.
Please tell me what the amount of the marshmallows are eg. weight or cups.
I see that one can purchase sugar free low carb marshmallows at one of our local stores.
Sorry, I honestly didn’t measure them. It probably comes to 4 or 5 cups if you chop them up.
Rocky road is the best of all flavors! This fudge is delicious and it definitely didn’t last long in my house. Guess I’m going to have to be making this often.
