This keto apple pie is a fun twist on the more traditional Low-Carb Pumpkin Pie but it uses zucchini, a rather unusual ingredient that works perfectly in this cake.

So is zucchini the new cauliflower?

Do you remember when people started turning cauliflower into everything from steaks to smoothes and our minds were blown? That’s how I feel about this Keto Apple Butter recipe. How can that be zucchini?

I guarantee you will never know. Those who tasted this keto recipe couldn't tell it was made with zucchini. Everyone thought it was apples! That is how good our sugar-free Apple Butter is. If you need to make this recipe nut-free, simply swap the almond flour with the same amount of ground sunflower seeds.

Using our low-carb apple butter as the filling for this lush and unique pie, with all the familiar spices and flavours of fall, will make you a dessert hero. Enjoy!

This looks delicious and I love the ingredients, they are so healthy! Beautiful recipe, can’t wait to try!

Thank you! You'll never know there are no apples, so good!

I have made this recipe today and I must say it is very good! I had a problem with quantities and I have concluded that, although I used 10cm tart pans, they must not have been as deep as those used to develop the recipe as I had too much pastry dough and filling, and the tarts cooked very quickly (almost burned them). Nonetheless, it was very tasty and next time I will use one 23 cm pan. Thank you, a very good recipe!
BTW, I made the crust with equal amount of sunflower seed flower and it worked very well.

Thank you so much Diane, that's good to know! I'll add a note. Glad you enjoyed!
PS: I amended the crust instructions based on this recipe: No Fail Low-Carb Pumpkin Pie (this way the crust will not brown too quick).

UPDATE: I tested this recipe as I was making pie crusts for a cranberry curd tart and I realised that it's not 4 but 8 mini pie crusts! I think what happened here is that the mini pie crusts Naomi used were much bigger. You can make up to 8 pie crusts if you press the dough in really thin, otherwise it will definitely make 6 pie mini pie crusts.

Yes,  I could definitely had made and filled 6 small (10cm or 4") pie crusts....but I think in the future I will make one large pie as it is easier to cut a small piece and manage my macros.  Perhaps making the crust with sunflower seed flour made it a bit thicker than fine almond flour would.  Nonetheless, it is a very good recipe....I have not had the flavour of apple pie in years and I thoroughly enjoyed it!
