The keto ingredient landscape is truly changing faster than you can bat an eye. It’s really quite mind-blowing! And for this baking obsessed gal, I can hardly tell you what a boon it is, all the new ingredients I get to play with.

Heretofore, something like Homemade Crunch Bars wouldn’t really have been possible on a keto diet. There just wasn’t a really good replacement for the rice crisps that conventional crunch bars use.

Well, there was, but it wasn’t an option that everyone completely embraced. I used crushed pork rinds in my Keto Scotcheroos and while it worked really well and is virtually carb free, not everyone found that so tempting.

But I will say, don’t knock it until you try it.

Keto protein cereals – crispy goodness!

I honestly don’t quite understand how they do it, but a number of brands have turned protein powders into crispy cereal bites. These are not something you could easily achieve at home – trust me, I’ve tried!

The three brands that I know of that are truly keto friendly are The Cereal School, Magic Spoon, and HighKey.

I have tried them all and of the three, I like HighKey the most by far. I like it best for flavor, as both the others have an aftertaste for me. My kids feel the same way. But that’s not to say you won’t like the other two brands.

Plus the HighKey Protein Cereal is more like little rice crisps, so it’s going to be really fun to play with for other desserts and treats.

Starting with these easy no-bake Keto Crunch Bars. So delicious, so crispy, so chocolatey!

How to make Keto Crunch Bars

These no bake keto chocolate bars are so easy, you can whip up a batch right now and enjoy them within the hour. I do still have some tips and suggestions, so you get the crunchiest, crispiest homemade Crunch Bars.

You will see I simply said nut butter of choice. You really can use what you like here. I used my homemade Keto Nutella because I can never get enough of it. But you could use peanut butter, almond butter, or sunflower seed butter.
Do make sure your nut butter isn’t too oily. If it’s the kind where the oil separates out, make sure to stir it well before measuring.
Use a powdered sweetener and sweeten to taste. It needs to be a confectioner’s style sweetener to avoid grittiness. And how much you decide to add depends on whether your nut butter is pre-sweetened or not.
Melt everything except the sweetener and the crisps together double boiler-style, to keep the heat very gentle. You don’t want to overheat your chocolate.
Remove the mixture from heat before stirring in the protein cereal crisps. An overly hot mixture will make your crisps less crispy!

Can you make these bars without the protein cereal?

You can indeed, but you’re looking at using crushed up pork-rinds. Please see my Keto Scotcheroos (linked above) for the full instructions.

Can you make these dairy-free?

Again yes, but you won’t be able to use the protein cereals, as almost all of them are made with whey protein. Sorry, my dairy-free friends, looks like you’re stuck with pork rinds again.

How to store your Keto Crunch Bars

These easy bars are best kept in the fridge, as they get rather soft at room temperature. Cut them into individual pieces and place in an airtight container.

There’s nothing here that will spoil so they can last several weeks.
