Line a baking sheet or tray with parchment paper.
In a microwave-safe bowl or using a double boiler, melt the dark chocolate until smooth. If using a microwave, heat it in 20-second intervals, stirring each time until fully melted.
Stir in the unsweetened almond butter into the melted chocolate until well combined.
Add in the chopped mixed nuts, unsweetened shredded coconut, chia seeds, erythritol (or your chosen sweetener), and a pinch of sea salt. Mix everything together until the nuts and other ingredients are evenly coated with the chocolate mixture.
Pour the mixture onto the prepared parchment paper, spreading it out to form a thin, even layer. You can use a spatula to help with this.
Place the baking sheet in the refrigerator for about 1-2 hours or until the chocolate bark has hardened.
Once the bark is set, remove it from the refrigerator and break it into pieces or cut it into squares using a sharp knife.
Store the low-carb chocolate nut bark in an airtight container in the refrigerator to keep it fresh. Enjoy as a delicious low-carb treat!Feel free to adjust the ingredients and measurements to your taste and dietary preferences. You can also experiment with different nuts or seeds to customize the flavor to your liking.
