Prepare all of your ingredients.

At the same time prepare your double boiler either the traditional way over the stove with a Bowl or a smaller pot above a big pot of boiling water.

Heat up your double boiler and make sure the water is simmering and the bowl is warm.

Into the dry bowl add your Cocoa Butter and let it melt fully.

Once your Cocoa Butter is completely melted, add your sweetener and let that melt into the liquid fully.

With your Cocoa Powder, I would suggest adding it only once you take the bowl out of the double boiler.

As this step is very optional it is up to you if you would like to add a few drops of vanilla or not.

Once everything is fully melted pour into your Silicone Chocolate Bar Molds and place it into the refrigerator.

With a dark chocolate bar, it should be ready after about 2 to 3 hours but I usually keep it always cool down overnight and only then store it wherever planned.
