Whisk the coconut oil, cocoa powder, sweetener, and a pinch of salt. Fill a muffin tin with paper liners. Pour a small amount of the cocoa mixture (1-2 tablespoons) into the paper cups. Drop a small spoonful of the almond butter (2-3 teaspoons) into the center of each cup. Divide remaining chocolate amongst the cups. If almond butter is sticking up, just gently press it down so each cup has a smooth top layer. Sprinkle each almond butter cup with a pinch of coarse sea salt. Freeze for one hour or until solid.
