Place the dark chocolate chips in a heatproof bowl.

Use a double boiler or microwave to melt the chocolate. If microwaving, heat in 15-second increments, stirring between intervals to prevent burning.

Once the chocolate is fully melted, stir in the chili powder and salt. Ensure the spices are evenly distributed for a uniform flavor.

Mix in the banana pepper sauce.

Pour the spiced chocolate mixture into a Ziploc bag. Snip off the end of one corner and pipe onto a wax paper sheet or into silicone chocolate molds. Spread it evenly for a thin bark or use molds for shaped chocolates.

Let the chocolate set at room temperature or refrigerate for faster results.

Once firm, break the chocolate into pieces or remove from molds. Serve as a standalone treat or pair with nuts, dried fruits, or cheese for a gourmet touch.
