The Best Healthy Apple Tart Recipe (keto-friendly)

Healthy Apple Tart Recipe

“An apple a day keeps the doctor away” isn’t just an old wives’ tale. Apples contain Vitamin C and antioxidants, which support the immune system among numerous other benefits, so why not make a healthy apple tart and allow yourself to have a guilt-free dessert?

This is such a super simple recipe, and you can use almost any firm fruit in season, such as pears, peaches, apricots, plums, or rhubarb. I am partial to apples, especially this time of year, and not just any apples, I really enjoy the Granny Smith variety.

I created this crust using almond flour and erythritol sweetener to keep things low in carbs, and by combining it with melted Kerrygold butter, there is no need to chill it ahead of time. It stays flaky, yet crisp, and complements the tartness of the apples, offering a nice balance.

Topping this healthy apple tart recipe with some whipped heavy cream mixed with BioTrust Platinum Premium Grass-Fed Whey Protein really completes the dish.

Chef Notes: I have also made this healthy apple tart recipe using coconut flour and coconut sugar, and it came out just as delicious. I have also used both Vanilla Cupcake Protein blend and Apple Pie Protein Blend. Really, any of the protein blends would be remarkable in this.
