When I was a kid, we thought Nestle crunch bars were the best. We couldn’t get them in Canada, so we would stock up when we went south of the border. They really weren’t all that exciting so I can’t quite remember why we liked them so much.
But making my own Keto Crunch Bars is a whole different kettle of fish. Don’t worry, though, there are no fish in these fun keto candy bars. Just delicious peanut butter chocolate sweetness with a satisfying crunch.
I love making my own healthier candy options like Keto Turtles and Keto Twix Bars. It’s truly amazing to turn old favorites into treats you can enjoy guilt-free!
Why you should try this recipe
I had an older recipe for Keto Crunch Bars but it was based on a crunchy keto cereal that no longer exists. So I took it off my website while I searched for a suitable replacement.
Because I loved these bars so much, and because readers have been asking about them, I decided to try using Magic Spoon cereal. They’ve been around for a while and they don’t look like they are going anywhere. But just in case, I have a few alternatives for you!
Other than sourcing the crisps, these keto chocolate bars are so easy to make. Honestly, they will take you all of about 10 minutes. And then you need a little patience to let them set and harden.
And with the switch in cereals, these bars also have almost 10g of protein. So they really are a healthy sweet treat!

- Crispy protein cereal: I took the cocoa Magic Spoon cereal and crushed it up a bit for these bars.
- Peanut butter: You can use creamy or crunchy, it’s up to you. I like Santa Cruz organic for recipes like this. You can also use another nut or seed butter.
- Unsweetened chocolate: This is not the same as sugar-free chocolate. This is pure chocolate with no sweetener whatsoever. I usually use Guittard because it has a smooth finish and doesn’t seize as easily as others.
- Oil: This helps thin out the mixture so you can whisk in the sweetener more easily. You can use coconut oil or avocado oil.
- Sweetener: Make sure that you use a powdered sweetener so that the bars don’t end up gritty. I used Swerve Confectioners.
- Collagen: This is technically optional but I recommend adding it, since it ups the protein and the health quotient. I used chocolate collagen protein. If you use plain you may want to add a little more sweetener.
- Hemp seeds: These tasty little guys are a nutritional powerhouse and add lots of protein and additional crunch. If you skip them, you may want to use more of the crispy cereal.
- Pantry staples: Vanilla and salt.
Step by step directions
1. Break up the crisps: Place the protein cereal in a re-sealable bag. Use a kitchen mallet or a rolling pin to break up the cereal into smaller pieces. (You don’t have to hit it hard, it breaks up easily).
2. Melt the chocolate and peanut butter: In a heatproof bowl set over a bowl of barely simmering water, combine the peanut butter, unsweetened chocolate, and oil, stirring until smooth and melted.
3. Sweeten the mixture: Remove the pan from heat and stir in the vanilla extract and salt. Then add the sweetener and collagen and whisk vigorously until smooth.
4. Add the crisps: Stir in the protein crisps and hemp seeds and stir to coat.
5. Spread in the pan: Press the mixture into a parchment-lined 8×8 inch baking pan as evenly as you can. Refrigerate until firm, about 1 hour. Lift the bars out by the edges of the parchment and cut into bars.
Tips for success
Always melt the chocolate double-boiler style, to prevent it from seizing. Don’t let the water underneath boil or simmer too vigorously. You want gentle heat here and you want to stir frequently until smooth.
If you can’t use this particular crispy protein cereal, you have some other options. I came across these plain whey protein crisps on Amazon that are entirely free from soy, corn, and gluten. I have purchased some, and although I haven’t tried them out yet, I can’t see why they wouldn’t work.
You can also use crushed pork rinds. Try to get them as plain as you can, with perhaps just some salt and no other seasonings. And don’t add them to the chocolate mixture while it’s still warm, as they will soften and be less crisp.
You can sweeten this recipe with your favorite sweetener. Just make sure it’s powdered to avoid any residual grittiness. Some brands of allulose dissolve well enough that you can use them even if they aren’t powdered.

This recipe turned out perfectly. The entire family said it is a keeper! Chocolatey goodness with a substantial crunch and just the right sweetness. At first I thought I could eat more than one, but one was perfectly satisfying.

Loved the crunch of these! Perfect to satisfy my sweet tooth. I am not a fan of the the cereal so may experiment with more hemp seeds and less cereal.

Hi! I was wondering if I could sub Roasted peanuts in place of the cereal for a MR. GOODBAR type of bar?
Shelly says
I couldn’t see why not! That sounds pretty delicious.
