If coconut butter is solid, you’ll need to warm it up to make it easily stirrable. It will scorch easily if microwaved, so it is better to place in a pan of hot water, in front of the vent of your oven while it is on, wrap in a hot pad or place in a very low (200 degrees or less) oven for 5 minutes at a time. Whatever method you use, check it often. Once you can easily stir it, pour half the contents into a pourable measuring cup or bowl. Add cacao powder, vanilla and salt, stir. Add remaining coconut butter and stir until well combined.
