Coconut butter is expensive. I attempted to make my own using coconut oil and shredded coconut and came up with a fairly nice batch, which I used in my Greek chocolate recipe. Turned out fantastic. You will need a good mixer to ensure the mixture gets creamy.
1 cup shredded coconut
1 TBSP coconut oil
1. Blend in a blender on medium power (Vita-mix preferred) for about 5 minutes, pulsing on high every 30 seconds. Refrigerate to set, about 1 hour.
