01 - Line a 12-cup mini muffin tin with paper liners and set aside.
02 - Melt the dark chocolate and coconut oil together in a heatproof bowl set over a pan of simmering water, stirring until smooth and fully combined.
03 - Spoon about 1 teaspoon of melted chocolate into the bottom of each muffin liner. Tilt or tap the tin gently to spread the chocolate evenly. Place in the freezer for 10 minutes to set.
04 - In a small bowl, mix almond butter, maple syrup, chopped roasted almonds, vanilla extract, and sea salt until well combined. Fold in the crispy rice cereal until evenly distributed.
05 - Remove the muffin tin from the freezer. Place about 1 tablespoon of the almond butter mixture onto the set chocolate layer in each cup, gently pressing to flatten and create an even surface.
06 - Cover each cup with the remaining melted chocolate, ensuring the almond butter layer is completely sealed and no filling is visible.
07 - Sprinkle a pinch of flaky sea salt on top of each cup while the chocolate is still soft, if desired.
08 - Return the muffin tin to the freezer for at least 20 minutes, or until the chocolate is fully set and firm to the touch.
