Start by preparing your baking sheet—line it with parchment paper to prevent the chocolate-covered beans from sticking once set.
In a medium-sized heatproof bowl, combine the dark chocolate chips and coconut oil. If you desire a hint of vanilla, stir it in at this stage as well.
Set the bowl over a pot of gently simmering water (this is the double boiler method) on medium heat. Stir the mixture continuously until the chocolate is completely melted and smooth. Be cautious to ensure that no water comes into contact with the chocolate, as this can cause it to seize up.
Once the chocolate is fully melted, remove the bowl from the heat. Introduce the roasted espresso beans to the bowl and stir them gently, ensuring that each bean is fully coated in the glossy chocolate layer.
Using a fork or a slotted spoon, carefully lift the chocolate-covered beans from the bowl, allowing any excess chocolate to drip off. Arrange them artfully onto the prepared baking sheet in a single layer to avoid clumping.
After all the beans are coated and spread out on the sheet, lightly sprinkle sea salt over them. This garnish will provide a delightful contrast to the rich sweetness of the chocolate.
Transfer the baking sheet to the refrigerator and chill for about 30 minutes, or until the chocolate is completely firm and set.
Once the chocolate has hardened, take the espresso beans out of the refrigerator. If any beans are stuck together, gently break them apart to separate.
Notes
These make a great gift when packaged in a decorative jar.
