This scrumptious keto low carb apple cake is a great recipe to serve to family and friends and just 3 g net carbs per serving! Yes, apple desserts can be enjoyed on a keto diet!

Are Apples Keto?

Keto or ketosis is a metabolic state in which your body is uses ketones for fuel instead of glucose so you can burn the fat on your body.

When you are on a ketogenic diet, many believe that certain foods are either "keto" or not keto, but everyone is different in how their own body stays in ketosis. 

While eating an entire apple for some people may kick them out of ketosis, using a small amount in a recipe like this, that has 16 servings using just one cup of apple, can be enjoyed on a keto diet and should not spike blood sugar.

In my opinion apples are a whole food, not a processed refined food and enjoying a little bit of the real thing is how to enjoy and have a sustainable low carb keto lifestyle. 

Low Carb Sugar Free Apple Cake

The fall is here and that means apple everything become the new favorite desserts of the season! Technically not a sugar free cake because apples do have natural sugar, there are no added sugars coming from white refined regular sugar or white refined flours.

Maybe enjoying a whole apple yourself would kick you out of ketosis, but 1 cup in a cake with 16 servings is a very small amount.

Once slice is just 6 total carbs and only 3 net carbs. I believe, enjoying seasonal items makes this a sustainable lifestyle I can stick with forever, how about you? 

What is Glucomannan?

I opted to use glucomannan powder in this recipe instead of xanthan gum as a thickener for this cake. I've used it to make an incredible gravy in my keto salisbury steak recipe. If it's an unfamiliar ingredient to you, let me explain why it's such a great option. 

Glucomannan is a natural, water soluble, dietary fiber made from the root of the konjac plant. This fiber is the same ingredient used to make Miracle noodles or Shiritayaki noodles. 

It's been used for a very long time in Japanese cooking as a thickener. Before I discovered it, I was using xanthan gum as a thickener for my gravy, but it gets somewhat goopy and a bit to gel-like.

Many people don't like the slimy texture that can often happen with xanthan gum. I'd recommend trying glucomannan if you're not a fan of xanthan, it's definitely a must in my keto kitchen!

Can I use Xanthan Gum instead?

Yes you can swap the glucomannan with xanthan gum if you prefer.

Nut Free Cake with Coconut Flour

I'd like to clear up this constant question get asked almost daily about whether coconut is a nut. While the US Food & drug Administration (FDA) claims that coconut is a tree nut becomes it comes from a tree, it is in fact a FRUIT.

People who have tree nut allergies may be allergic to coconut as well, but being allergic to coconut is not the same as having a tree nut allergy.

My own son was diagnosed with a Peanut and Tree Nut allergy at the age of 2. He has safely eaten coconut all these years without issue and he is now 14. Coconut is a fruit, called a drupe. It's like a peach with a pit. 

The American College of Allergy, Asthma and Immunology says it well: "Coconut is not a botanical nut: it is classified as a fruit, even though the FDA recognizes coconut as a tree nut.

While allergic reactions to coconut have been documented, most people who are allergic to tree nuts can safely eat coconut. If you are allergic to tree nuts, talk to your allergist before adding coconut to your diet."

Can I Make this an Almond Flour Apple Cake instead?

You really can not evenly swap coconut flour with almond flour. Coconut flour requires more liquids, eggs and is very dense so you use a lot less.

You would need to double or even triple the amount of almond flour to create the correct texture that the coconut flour provides.

Directions

Preheat your oven to 325 degrees F. Grease a silicone 9 inch bundt cake pan and place on a small baking sheet pan lined with parchment paper. Set aside.

Place chopped apples and cinnamon together in a large bowl and stir to coat the apples. Set aside.

Whisk dry ingredients together; the coconut flour, brown sugar sub, baking soda and powder, apple pie spice, salt and glucomannan and add to a stand mixer or large mixing bowl.

Pour the sour cream, butter and heavy cream into the dry mixture in the stand mixer or medium bowl. Blend until combined. Mix in the remaining ingredients; apple extract and stevia.

Add one egg at a time into the batter until combined.

Take half of the apples and spread them all around the bottom of the bundt pan. Spread half of the cake batter over the apples in the bundt pan. Spread the remaining apple slices over the batter and then the remaining batter over the apples.

Place the pan in the middle of the oven and bake for 50-60 minutes or until a toothpick in the center comes out clean.

Allow to cool. Once cooled, place your serving plate over the top of the bundt pan and flip cake over. It should easily release from the silicone pan. Slice into 16 servings.
