In a dry skillet, toast the quinoa on medium heat until it begins to pop and is fragrant, about 1 - 2 minutes. Toss it a few times to ensure even toasting.
Add quinoa to a high powered blender and blend on high until it resembles the texture of flour. Transfer to a food processor.
Add dates, cocoa powder and coconut oil. Process until combined.
With processor running, add water 1 tablespoon at a time until a dough has formed.
Line a small container (sandwich sized works great) with plastic wrap. Press dough into container and smooth with hands. Sprinkle with sea salt (if using).
Place in freezer for 3 - 4 hours until set.
Remove from freezer, a cut into small, 1/2" squares (remember these are bite sized!). Store in freezer and enjoy whenever the chocolate craving hits!
