Toast the almonds (optional but recommended): Preheat the oven to 325°F (165°C). Spread almonds on a baking sheet and toast for 8–10 minutes until fragrant.
Let them cool. Toasting adds depth and extra crunch.
Melt the chocolate: Add chocolate and coconut oil to a heatproof bowl. Melt gently over a double boiler or in the microwave in 20–30 second bursts, stirring between each session until smooth.
Don’t overheat.
Sweeten and flavor: Stir in the keto sweetener and vanilla, if using. Taste a small dab and adjust sweetness. If adding cinnamon or cacao nibs, stir those in now.
Combine with almonds: Add the almonds to the melted chocolate and stir until every nut is coated.
If using coconut or other nuts, fold them in evenly.
Form the clusters: Line a baking sheet with parchment. Use a spoon to drop small mounds (about 1–2 tablespoons each) onto the sheet. Aim for similar sizes so they set evenly.
Finish and set: Sprinkle with a light pinch of flaky sea salt.
Chill the tray in the fridge for 20–30 minutes or until firm. For a snappier texture, chill a bit longer.
Serve: Enjoy straight from the fridge or allow them to sit at room temperature for 3–5 minutes if you like a softer bite.
