Place the almonds, oats, coconut, and lucuma powder in the bowl of a food processor fitted with the steel chopping blade. Process until finely ground. Transfer to a bowl and set aside.
Place the pitted dates into the food processor. Pulse a few times, then turn on high and let process until a thick paste forms. Stop motor, remove top, and scrape down sides. Add the coconut oil, honey, vanilla extract, and sea salt. Process again until well-combined.
Add the almond, oat, coconut, and lucuma mixture to the food processor, along with the activated charcoal. Pulse a few times, then process until the mixture comes together into a ball. There will be chopped nuts visible, but the mixture should be well-combined. If it doesn't come together or if it's dry and crumbly, add a little more honey and process again. It should feel soft and pliable like playdough.
Line an 8-inch square baking pan with parchment or waxed paper. Press the bar mixture into the pan in a smooth, even layer. Refrigerate or freeze until firm enough to cut into bars, then cut into 8 rectangles.
To store, keep well-wrapped in waxed or parchment paper in an airtight container in the fridge or freezer. Will keep about one week refrigerated, or several months frozen.
