Fruit isn’t something that you can enjoy a lot of on the keto diet. Berries are the exception because of their low sugar content.

Berries are also one of the healthiest foods you can eat on the planet. They contain unique antioxidants called anthocyanins that are responsible for giving berries their vibrant colors.

Research shows that anthocyanins contain antimicrobial and antioxidant properties, improve neurological health and vision, and protect against many non-communicable diseases (1). 

They also have anti-obesity effects, antidiabetic properties, and may help improve autoimmune arthritis (2, 3).

The healthy fats  provided by the dairy products help you absorb the anthocyanins and other antioxidants in blackberries, which makes this recipe nutritionally-balanced. 

We recommend using organic dairy products, including pasture-raised eggs and antibiotic-free sour cream, butter, and cream cheese. This will help you get the most nutrition from your food. 

Collagen is the most abundant protein in the body. It is found in your connective tissues. It’s a very helpful supplement on the keto diet because it promotes the growth of healthy hair, skin, and nails. 

Make sure your collagen comes from clean sources, too. We like products that are made from organic, grass-fed collagen. This ensures that your collagen product contains all three types. For a list of recommended products, check here!

You can use any keto sweetener you have, including stevia or monk fruit. This recipe calls for erythritol because it does well in baking products. You will also get a bit of sweetness from the blackberries and the vanilla extract.

If you have extra time, we recommend making the frosting! It gives your cheesecake a decadent glaze that will perfectly please any guest. They won’t be able to tell it’s low-carb! 

This recipe should keep in the freeze well if you have any leftovers, but we don’t think you will!

Let’s Do It!

Place blackberries into a small saucepan. Add some erythritol and water. Heat the mixture and crush with a spoon to release juices.
