Half a ripe avocado with a sharp knife and remove the pit. Remove the skin, by inserting a spoon between the flesh and the skin. Add the peeled avocados to the bottom of a blender cup.
Add the scoops of protein powder to the blender cup. Feel free to use any neutral-flavored or vanilla-flavored protein powder for this step.
Add the unsweetened coconut milk and the syrup to sweeten the smoothie ingredients. Again, feel free to use powdered erythritol or liquid stevia here instead. You can also choose to use any Keto-friendly unsweetened milk (think almond milk, cashew milk etc.).
Blend all the ingredients together using a stick blender until very smooth. You can use a small smoothie blender as well, but since the amount to be blended is small, stick to using a small blender so the blades can reach all the ingredients. The smoothie is on the thicker side so you can eat it with a spoon. If you want it a bit thinner, add more unsweetened coconut milk.
Pour the smoothie into a chilled bowl. You can keep a bowl in the fridge to be sure that is it nice and chilly. This will help keep your smoothie cold and enjoyable.
Top with berries to the one side, chopped dark chocolate on top of the berries, and the coconut flakes. Feel free to add additional syrup over the top of the smoothie for another kiss of sweetness.
