Pre-heat oven to 350 degrees and spray a 9 x 13 baking pan with cooking spray.
In a food processor, pulse together dried tart cherries, oats, walnuts, flax seed meal and salt until finely chopped, roughly the consistency of sand.
In a large bowl, whisk together eggs, honey, cocoa powder and vanilla until smooth. Add the oats mixture to the bowl and stir until evenly coated with the chocolate honey mixture.
Add dark chocolate chips to the bowl and stir again. Pour mixture into prepared baking dish and spread out in an even layer.
Sprinkle additional tart cherries and chocolate chips on top before baking 20-25 minutes.
Let bars cool completely before slicing.
While the bars will taste delicious warm or room temperature, they slice best when chilled in the refrigerator 3 hours or up to overnight. Wrap individually in plastic wrap and store in the refrigerator for up to 10 days.
