Place the chopped bittersweet chocolate in a heatproof mixing bowl.
Gently melt the chocolate using a microwave in 20-second bursts, stirring between each, until smooth and glossy.
Add the vanilla extract and a pinch of sea salt to the melted chocolate, stirring until well combined.
Fold in the cocoa powder to deepen the chocolate flavor and create a rich, even color.
Stir in the chopped roasted almonds for bursts of crunch in each bite.
Spoon the mixture into a mini muffin tin or silicone mold, filling each cavity almost to the top for a compact, bite-sized shape.
Chill the mini bites in the refrigerator for 15 minutes until set and firm.
Once chilled, gently pop the bites out of the mold—expect a shiny, slightly crackled surface with a dense, fudgy interior.
Arrange the chocolate almond bites on a serving tray and enjoy immediately or store in an airtight container in the fridge for up to a week.
