To make this dark chocolate bark, start by toasting the quinoa. Heat a small pan, on the stove, over medium-low heat.
Once the pan is hot, add in the quinoa, stirring it frequently so that it gets toasted but doesn't burn. After approximately 4-5 minutes, the quinoa will turn a golden brown color and start to pop.
Once the quinoa begins to pop, stir it for another minute, then remove it from the heat and set it aside.
Next, prepare the chocolate. Add the chocolate chips and coconut oil to a bowl and microwave it in 2-3, 30 second increments, until the chocolate is smooth. Be sure to stir the chocolate and coconut oil together in-between microwaving, to ensure that they are fully incorporated.
Then, chop the raspberries into small pieces and add them into the bowl with the melted chocolate. Stir until the raspberries and quinoa are fully incorporated into the chocolate.
Line a baking sheet with parchment paper, then spread the chocolate mixture out across it in an even layer. You can use a spatula to ensure that it is all spread out evenly.
Add additional raspberries to the top of the chocolate, as well as a pinch of flaky salt, if desired.
Transfer the baking sheet into the freezer for a minimum of one hour, or up to overnight, until the chocolate has solidified.
Once it's done, remove it from the freezer, break it into pieces, and enjoy! Store any leftovers in the refrigerator for up to one week, or in the freezer for up to one month.
