Are Blackberries Keto?

Blackberries can be enjoyed on a keto and low carb diet due to their high fibre content. In small amounts, like most berries, they are a great low carb fruit. When you need your fruit fix on a low carb diet, reach for a berry!

How to Make Keto Lemon Blackberry Cupcakes

Coconut flour is used with these keto lemon cupcakes as it’s one of our favourite low carb flours.  It is highly absorbent and take happily take a lot of moisture.  If the cupcake batter looks too thick add more water or perhaps a tablespoon of coconut milk.  It should be a smooth consistency.

Whilst the cupcakes are baking, make the blackberry cream cheese topping and place it in the fridge so it can firm up a bit to make it easier to pipe. If you don’t care about the piping, simply slather the topping over the lemon cupcake, pop a blackberry on top and you are done!
