These low carb apple muffins have a buttery cinnamon crumble topping and make a delicious breakfast or gluten free sweet treat.
If you enjoy my mock apple crumble but can’t trust yourself with portion control, then enjoy one of these muffins at under 4g net carbs each. Baked with almond flour and chayote they are a great low carb muffin.

The muffin has a firm yet moist texture with the cinnamon coated chayote pieces giving a good impression of apple. The crispy crumble topping is not too sweet and provides an added crunch. I took a batch of these to my midweek art class and disappeared in almost record time. No-one else is following low carb or gluten free, so I took that as a great compliment to these low carb muffins!
Can I Replace the Chayote with Zucchini?
Zucchini makes a great low carb mock apple replacement, but I would use the yellow variety if you can use it as it is a bit sweeter than the green zucchini. Simply chop the zucchini into to small pieces, gently fry them in butter until brown and add the spices with a dash of lemon juice.
You may want to add an additional drop of apple extract if you are looking for a strong apple flavour.

Low Carb Sweetener
I have baked these low carb apple crumble muffins a few times and have enjoyed them with erythritol as well as Lakanto Golden. The golden sweetener adds another layer of taste and is great in the crumble topping. If you use xylitol, keep firmly away from your animals as it is extremely toxic. If your house is animal free, it’s a great alternative to erythritol and often easier to obtain.
These muffins can be a dessert on their own if you serve with cream, cinnamon ice cream or a drizzle of keto caramel sauce.

Can I Use Coconut Flour?
If you do not like almond flour or have a nut allergy, you can substitute the flour with coconut flour. Reduce the quantity of the flour to ¼ cup as you don’t need as much volume. You might need to add additional liquid if the batter is too dry.
