01 - Line a 12-cup mini muffin tin with paper liners.
02 - Melt the dark chocolate and coconut oil together in a heatproof bowl set over simmering water (double boiler) or in short 20-second bursts in the microwave, stirring until smooth.
03 - Spoon about 1 teaspoon of melted chocolate into each liner and use a spoon to coat the bottom and sides. Reserve the remaining chocolate.
04 - Chill the muffin tin in the freezer for 10 minutes until the chocolate is set.
05 - In a small bowl, mix almond butter, maple syrup, vanilla, and sea salt until smooth.
06 - Divide the almond butter mixture evenly among the chocolate cups (about 1 heaping teaspoon per cup). Flatten the tops gently.
07 - Cover each cup with the remaining melted chocolate, smoothing the tops.
08 - In another small bowl, whisk together miso paste, maple syrup, and warm water until smooth to make the miso glaze.
09 - Drizzle a small amount of miso glaze over each cup. Swirl gently with a toothpick for a marbled effect.
10 - Sprinkle with chopped roasted almonds and flaky sea salt if desired.
11 - Chill the cups in the refrigerator for at least 30 minutes, or until completely set.
12 - Serve chilled or at room temperature. Store leftovers in an airtight container in the refrigerator.
