I was going to call this recipe "sugar free flapjacks", because that's what we call granola bars over here in the UK. However, when I did a bit of research I found that in the US, flapjacks are not granola bars at all, but pancakes!
It's a bit of a biscuit / scone situation (read more in my post Speedy Savoury Scones). So, to keep things very clear and simple, let's stick with granola bars for this one.
Are granola bars keto friendly?
Traditional granola bars have a base of oats and contain copious amounts of honey, golden syrup or dried fruit such as dates to stick everything together. Yum, but a combination that will send your sugar levels sky-high.
However, with a few ingredient changes it's easy to make a sugar free granola bars recipe that is fit for a low carb diet. You simply replace the oats with nuts and seeds and use a low carb sweetener such as erythritol.

How do you get low carb granola bars to stick together?
There are many low carb snack bar recipes out there that use sugar free syrup (aff link) as a binder. It behaves similar to golden syrup - it's nice and sticky.
I like the taste of fibre syrup and tolerate it well. However, some people have reported that it raises their insulin.
When I made my Apple Cinnamon Granola Bars I used flaxseed to stick the bars together. Chia would be another good alternative.
This time I went for a mix of flax and a whisked egg white, which worked great.
How to make keto granola bars - step by step:
1.) Pulse the nuts and seeds in a food processor until you have some smaller and some larger pieces.
Some nuts you can buy pre-chopped to save this step.
2.) Stir all dry ingredients in a bowl, leaving a few chocolate chips to decorate on top.
Then whisk an egg white and add it to the bowl together with the vanilla extract and almond butter. Stir until combined.
Check the sweetness and add more erythritol or sweetener of choice to your liking. (I don't have much of a sweet tooth).
3.) Pour the mix into a baking tray lined with parchment paper and press down well to compact. (I did not press the mixture much in my first attempt which made my bars more fragile and prone to crumbling).
Press the remaining chocolate chips on top and bake for circa 20-25 minutes or until lightly browned.
Healthy granola bars recipe tips
Let your keto granola bars cool completely before cutting. They are quite soft when hot, but firm up and get nice and crispy when cold.
If you use 90% dark chocolate, the nutritional values stay the same as with sugar free chocolate. With 85% dark chocolate, net carbs increase to 3g per bar.
It does not matter whether you measure the nuts whole or chopped when using cups - the volume is similar.
Do not omit the ground flax - it helps to bind the bars together with the egg. You could swap it out for chia seeds though.
Homemade granola bars variations
You can use any nuts you like (or have available at home). I've made lovely chewy granola bars using macadamia nuts, hazelnuts and even pistachios. Just be aware that cashews are higher in carbs than other nuts.
If you like coconut, you can use desiccated unsweetened coconut here too. Just swap out some of nuts and seeds.
The chocolate chips are entirely optional - if you're not keen, simply leave them out. You could use freeze-dried raspberries or dried cranberries if you're up for a fruity variation.
You can swap out the almond butter for peanut butter. If you want to omit nut butters altogether, use 1 tbsp coconut oil instead.
Optional chocolate drizzle
Melt either ¼ cup of sugar free chocolate chips or 4 squares of dark chocolate (85% or 90% cocoa solids) and drizzle over the bars. This is not included in the nutrition calculation.
Store in an airtight container at room temperature for 4-5 days or in the fridge for about 1 week.
And yes, you can freeze them, too!
