The Keto Ingredients in Keto Protein Bars

Keep reading for more details on the ingredients, substitutes and step by step instructions on how to make our delicious keto protein bars

Keto Protein Powder – I use an unflavored Whey Protein Isolate. You can choose from your best keto protein powders both flavoured or unflavored for this recipe.

Sukrin Syrup – You will need a sticky keto sweetener like Sukrin Gold to make these bars. It is what holds the bar together.

MCT Oil – I use MCT Oil but you can use coconut oil or a neutral taste olive oil if preferred.

Chefs Tip!

Tip #1 – Don’t add all the WPI at once.

I like to add about three-quarters of the powder and add as I mix the protein bars.

It makes it easier to mix and allows me to judge whether I need more. Some WPI powders are more absorbent. If the mixture is dry add some more syrup or oil to make it smooth.

Tip #2 – Mix with your hands. I put on gloves and mix this way. It helps make a better smoother bar and you can feel if the mixture needs more of any particular ingredients.

How to Make Keto Protein Bars

Step 1. Heat the syrup. It doesn’t need to be too hot, especially if you are mixing by hand. If you do not have a microwave this can be done over a saucepan of simmering water.

Step 2. Add the ingredients to the bowl. (See above for tips).

Step 3. Mix with gloved hands until it is smooth. It should stick together and be slightly sticky.

Step 4. Line a slice tray with cling film and press the mixture into the tray evenly. As you can see from my picture I chose to top with extra toasted almonds. Cover and chill. Cut into bars or bites and enjoy!

FAQS and Hot Tips!

Are keto bars a meal replacement?

That is up to you. Depending on the protein powder used the bars can be a good source of protein and may give you the feeling of fullness. Personally, I wouldn’t use a bar as a replacement for real food though.

What store bought bars are keto friendly?

Most bars found in the supermarket do contain maltitol. If buying a protein bar look for brands like Locako.

Are low carb bars good for weight loss?

Weight loss is linked to what you eat overall and when. I wouldn’t say a keto protein bar could tip it either way.

What is the best keto protein powder to use?

Up to you. I choose a WPI but if you need a dairy-free protein powder I would go with pea protein.

  • Heat the syrup in a large heat-safe bowl in the microwave for 45 seconds or until you see it start to bubble.
  • Add all the remaining ingredients and stir.
  • Using your hands really mash these ingredients until it starts to form a sticky but dry consistency.
  • Press into moulds of choice or slice tray. Refrigerate until set


I use syrups like Allulose Syrup, Nothing Naughty (tapioca derived) or a non-gmo brand like ChocZero.
This recipe yields approximately 12 servings. Actual number of servings will depend on your preferred portion sizes. The bars can easily be made into smaller bite size portions.
To calculate the weight of one serving, prepare the recipe as instructed. Weigh the finished recipe, then divide the weight of the finished recipe by 12. Result will be the weight of one serving. 
Nutritional values shown are guidelines only. They are for 1 serving using the ingredients listed. Actual macros may vary slightly depending on product brand and types of ingredients used. 
I do not use weight per portion for the nutritional as it would require exacting ingredients and uniform bars and ingredients distribution in each bar e.g. does each bar have exactly 15 pieces of almond weighing X. This is why recipes are based on the ingredients used and divided into portions as a rough guide only!
All recipes have been tested using all of the cooking methods included by various recipe testers.
Store in an airtight container in the fridge for up to 10 days. Alternatively, store in an airtight container and freeze.

    So good! They are in the freezer now for a long plane trip coming up next month! It’ll keep me happy during the trip! So much better than ANYTHING I can buy in stores. Super easy recipe too. Oh, I had only WPC so made them with that. They remind me a bit of Halva, which I absolutely love, but without any guilt!!

    Hi, I tried these but they did not set. I used maple syrup because I didn’t have Sukrin. Could this be the reason? Any other substitutes I could use?

    1. Megan Mad Creations Hub

      If you used real maple syrup then yes they should have set. If you used sugar free maple syrup then it is likely your problem as many brands are mostly water. Sukrin syrup has zero water where say Lakanto syrup is mostly water and will not work.

    I make these with natural pea protein and Fibre syrup from Nothing Naughty in NZ (the closest thing I can find to Sukrin syrup). Have made with both natural and a mix of natural/caramel fiber syrup and both are good. Ran out of MCT oil today so used coconut oil instead. Thanks Megan 🙂

    1. Megan Mad Creations Hub

      So happy you improvised Paula.

    These Protein Bars are so good. Make your own and you will see they are better than bought ones. They are quick and so easy to whip up. Low carb and so delicious 😋🥰

      I love them too Lucy. Thanks for taking the time to leave a review.

    I am from Germany and there is a recipe as a substitute for sweet sirup.
    If you use it instantly
    106 ml of water
    54 g of erythrit
    1g xanthan
    An a messerspitze (a tini little bit of) Stevia
    Boil water with eritryth until clear, than put the xanthan and stevia in the pot… Stir like crazy as the xanthan will want to build pieces and not want to be a cristal clear part of the sirup if you don’t stir stir stir
    Now you start at step 2 of the recipe above.
    Works for me… It is some fluffy stuff. Tomorrow I want to dip them in selfmade chocolate… Yummi

    If you want to prepare sirup you have to use “destilliertes Wasser” – Water für ironing? Without any minerals… So the sirup will stay clear. And you must! fill it in a glas bottle.


    1. Megan Mad Creations Hub

      Hi Nio, I am totally going to try this and see how it goes. Thanks for the recipe and tips.

  8. Tracy

    I was DESPERATE to try this but didn’t have the syrup… but I did have Inulin! I heated a cup of Inulin with half a cup of water and when it was boiled for a bit and clear I added it to the dry ingredients. The WPI I used stayed soft and really sticky too so I added some micellar that I bought for another recipe. Not too shabby!

    1. Megan Mad Creations Hub

      That sounds super interesting Tracy I hope you show us what it looks like through social media

    Could I use sugar free maple syrup instead of the fiber syrup? Thanks!

    1. Megan Mad Creations Hub

      Hi Lauren, no it does not work. The SF maple syrup has zero viscosity vs fibre syrup.

  10. Bridget

    Is there any substitute for the fiber syrup? It contains IMO’s which I’m trying to avoid as they raise blood sugars. Many thanks.

    1. Megan

      Hi Bridget, I tend to address all substitutions in the blog posts. The Sukrin fibre currently has no keto alternatives in Australia.

  11. Kim

    Hey, just wondering as i don’t have a microwave would you heat this up on double boiler or in thermomix? Also just brought 3 books and a microwave used for pastry recipes what method would you suggest??
    Thanks Kim

  12. Kristen

    Can these be frozen? If not, how long would they last in the fridge?

  13. Chelsea

    I have pea protein isolate vegan powder as it was on sale at Aldi’s. Could I use this?

    1. Megan

      You could Chelsea but it may make it crumblier and just taste the protein powder first. If it is nice and neutral in flavour than it should be fine. If it doesn’t taste good then I wouldn’t use it in this recipe as the taste will come through

  14. Susan

    Hello, Looks good! Do you think heated Sukrin Gold would work as I don’t have the syrup? Thank you. 🌻

    1. Megan

      I dont think it will, even the gold syrup is different in this recipe than the clear

    I really enjoy 2 of these at night with a herbal tea 🙊.
    I also use Macadamia nuts instead of the slithered almonds. Such a good recipe!

  16. 5 stars
    I made this and went back for thirds to make sure it tasted so good and wasn’t me being a guts! And in my head I said Omg I felt guilty but if the whole batch is 4 g net carbs … my guilt appeased and ok just one more piece… try this it is ohhh so good!!

  17. Leisa

    5 stars
    Megan these are so good. I made a few changes as I didn’t have all the ingredients but still yummy. I used the sukrin gold syrup instead of the clear, coconut oil instead of MCT and also put them in silicone candy moulds. Even hubby liked them so a winner in our household.
