How to make Keto Snack Bars

These are chewy bars (as most keto bars are without added sugars and starches etc.) with a rich, ganache like flavor which pairs perfectly with hazelnuts, almost like nutella!

These keto friendly snacks can be prepped in 15 minutes or less, perfect to prepare in advance.

After an hour or so in the fridge these come out with the just the right amount of firmness to eat without them disintegrating like so many low-carb bars do.

Being so rich in flavor, you might wonder about the carb content? These do not contain any sugar or overly processed ingredients. So these are 100% Keto friendly snack bars with only 2 net carbs per bar.

Upgrade Your Low Carb Snack Bars

Working out a lot? You can add some more protein to these these bars by adding some Keto protein powder, chocolate or vanilla flavor, or even hazelnut if you can find one.

We like the Perfect Keto collagen protein powder as a well rounded addition to the keto diet, ideal if you’re more active and do regular exercise/weightlifting and want to add more protein to your keto diet.

Another great tweak to these Keto snack bars is to add a pinch of instant coffee granules for more of a nutty, mocha flavour and a caffeine boost.

Those would go brilliantly with our Coffee Mocha Smoothie for a quick, fat fuelled start to the day.

Once you make these, be sure to store in the fridge, wrapped individually in parchment paper. As they have a high-fat content from the nuts and coconut oil, they may melt and bind to one another if allowed to warm up.

For longer shelf life, you can freeze the bars in the freezer. Make sure you remove from the freezer at least 10-15 minutes before consuming it.

Tips and Recommendations for the Best Keto Chocolate Bars

  1. Check your nut butter: Some people find their keto candy bars don’t set well in the fridge, others find that the mixture can be too dry to spread. This can usually be traced back to the huge variety you find between different brands of nut butter.
    For the best low carb chocolate bars, try to find nut butters without any added ingredients (especially sugar to keep things keto), but also look out for other additives, as these can alter the texture and ability of the mixture to set.
    Use a nut butter that is somewhat runny, not the dried, hard bits you often find at the bottom of an older jar. You want to be able to bind all the ingredients together well so they don’t crumble.
  2. Chill your bars thoroughly: It’ll be tempting to cut the time short, but these really do need a decent amount of time in a cold fridge, an hour is the minimum really. If for some reason they don’t set, try putting your keto snack bars in the freezer, you can store them in here then move the fridge shortly before eating if you prefer a more solid bar.
    Just remember to put a layer of parchment paper or similar between bars when storing, so they don’t stick together!

  1. These look good but why not use hazelnut butter instead, since we want to end up with a paste? I’m new to keto recipes so, is there a reason here to start from whole hazelnuts instead of hazelnut butter? Thanks

  2. Does the size of the loaf pan make any difference and I assume parchment paper is lining the pan OR do you need one in an aluminum pan-size sprayed w/cooking or baking spray-8.5 x 4.5 x 2.5 Inch
    Please advise-thank you👍🏼

    • Hi Amber, I’ve just updated with cup measurements for you – I’m in the UK here so more used to using grams, sorry! If you give it a go with those measurements let me know how it goes. Thanks!

  3. Hi, these are delicious but I can’t get them to set…I’ve had to put them in the freezer, do you know why this would be?

    • Hi Amy, thanks for your comment! I’m not too sure exactly what the cause would be. I would first check the nut butter you’re using – I find the consistency can vary a lot from different brands, some much more oily than others. The other thing to watch for is any additives to the nut butter, as some have additives put in specifically to prevent the butter from getting too hard when refrigerated.

      Let me know how they get on in the freezer. I’ll do a little more research and add a note to the recipe for future if I can find the cause!

    • Hi Jessica, thanks for your comment! Not too sure what would cause the mix to be too dry, it could be a few different things. It does need to blended for a long time for the hazelnuts to get the hazelnuts to really break down, release their oils into the mix and go smooth.

      It may also come down to the consistency of your nut butter. Brands tend to vary a lot so it’s worth experimenting. As you can see from the pictures, the almond butter we used was quite smooth and spreadable, but I know I’ve bought plently of nut butters that were almost rock solid coming out of the jar!

      If in doubt, you can always increase the amount of oil or nut butter slightly to soften up the mix further next time.

  4. I use ground almonds as I dont find any difference except price and added a bit extra peanut butter with the tablespoon of extra of coconut flour and they worked out perfect. I just use a nutra bullet as well. I didn’t have all almonds but had a pack of flacked almonds worked just the same

  5. Hi mine did not set in the fridge, they remained the same texture
    Can I put it in the freezer? Also where do u think I went wrong?

    • Hmm not too sure, did you make any substitutions? In particular the coconut oil or nut butters as they’re going to help set the mixture.

      I would check the ingredients on your nut butter for any additives etc. Often they add stuff to keep the nut butter spreadable even at low temperatures, this could be the cause perhaps?

    • Hi Nicole, thanks! You can swap out the almond flour for coconut flour, although it tends to be more absorptive than almond flour and dry things out. To balance that out I’d use a little more coconut oil.

      Let me know how it goes!
