Ingredients You’ll Need

To make it, you’re going to be using butter and sour cream. These add fat and make the cake nice and luscious.

Then for added sweetness, you’ll use erythritol. I love using erythritol for my baking.

1. Erythritol

It’s not too sweet and won’t spike your blood sugars. If you need to stock up on some for your holiday baking, you can do so here.

2. Almond Flour

You’ll also be using almond flour instead of regular flour. Almond flour has fewer carbs and more fat than regular flour, making it perfect for low carb baking.

It also has a low glycemic index and is an excellent source of magnesium. So, it may even help reduce your blood sugars.

And using almond flour in your baking is pretty easy. Simply substitute the same amount of almond flour for wheat flour in your recipes.

If you’re new to almond flour, definitely give it a try. Here is the almond flour that I recommend.

3. Cocoa Powder

To add the chocolatey layers of flavor, you’ll need some cocoa powder and sugar-free chocolate chips.

These not only add flavor but a ton of nutrition as well.

For instance, just 1 tablespoon of unsweetened cocoa powder contains 10% of your daily copper and manganese needs and 7% of your magnesium needs.

Magnesium and manganese are important for healthy bones. While copper is an important antioxidant.

4. Coconut Flour

And for the coconut flavor, you’ll be adding unsweetened coconut chips.

Coconut is not only yummy but good for you as well. It contains fats called medium-chain triglycerides that can promote ketosis.

It also contains tons of minerals. Some of these include manganese, copper, selenium, magnesium, phosphorus, iron, and potassium.

Do note that this cake has a slight hint of coconut. That’s because you’re only using 1 teaspoon of coconut chips.

But, if you like more of a coconut flavor, feel free to add more coconut chips.

5. Eggs

And let’s not forget about the eggs. You’ll need one egg to bind everything together.

Eggs have had a bad rap in the past because they’re high in cholesterol. High blood cholesterol increases your risk of heart disease.

However, research shows that eggs don’t affect your blood cholesterol levels. In fact, eggs may actually be good for your heart because they can increase your heart-protecting HDL “good cholesterol” levels.

So, don’t be afraid to use eggs in your baking or in your other recipes as well.
