1. Line a baking sheet with parchment paper and set it aside.

2. In a microwave-safe bowl, combine the dark chocolate and coconut oil. Microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth.

3. Stir in the vanilla extract into the melted chocolate mixture.

4. Add the almonds to the chocolate mixture and stir until all the almonds are evenly coated.

5. Using a fork or a slotted spoon, remove the almonds from the chocolate mixture, allowing any excess chocolate to drip off, and place them onto the prepared baking sheet.

6. Optional: Sprinkle a pinch of sea salt or cinnamon over the chocolate-covered almonds for added flavor.

7. Place the baking sheet in the refrigerator for about 15-20 minutes, or until the chocolate has hardened.

8. Once the chocolate is completely set, transfer the dark chocolate covered almonds to an airtight container or enjoy them right away!

Note: You can store these dark chocolate covered almonds in an airtight container at room temperature for up to two weeks. Enjoy them as a delicious keto-friendly snack!
