This is not your usual apple butter because there are no apples in this recipe. It has all of the amazing flavours of apple butter but a fraction of the carbs!

From the bucket of “not sure this is going to work”, to duping my partner that he was actually eating apples, this keto “apple” butter is definitely a success story.

I’ve used zucchini to make this apple butter which is all I had access to, but I imagine that other varieties of summer squash would also work well. And to flavour this butter I’ve kept it simple and used cinnamon, however you could add some additional autumnal spices like nutmeg or cloves for a richer, spicier flavour if you prefer.

We used zucchini to replace apples in other low-carb recipes and it was always a success. If you love apples, give these keto recipes a go!

Just finished making this. It’s been years since I could eat apple butter. It’s a personal favorite. This turned out Delian’s I’m beyond grateful to you

Thank you for your lovely feedback! 😊

I made this yesterday and served it with pork steaks.  My family LOVED it!  The kids couldn't believe that it was zucchini when I told them.  Great job.

Thank you Jennifer, it's our favourite too! 😊 It's incredible how much is tastes like apples!

1 tbsp was way too much cinnamon.  I think 1 tsp would almost be too much. It was so yummy, and tasted like apples before the cinnamon was added. Bummer.  

I'm sorry to hear that Jan, that must have been disappointing! I actually use more than that so I added a note to the post as this is the kind of ingredient that should be used to taste.

I used to make apple butter in a slow cooker, I bet it would work for this recipe too. I’m definitely going to try out this recipe!

Oh I bet it would work great in a slow cooker!
