Step 1: Line a 12 cup muffin pan with liners, then lightly spray the liners with cooking spray
Step 2: Pour oats in a food processor bowl, then whirl until very finely ground, about 2 minutes. Add cocoa, flax meal, baking powder, baking soda and salt. Whirl until combined, about 30 seconds.
Step 3: In a large bowl, whisk egg whites with applesauce, yogurt, agave syrup and vanilla until combined. Add to the food processor bowl along with the hot water. Whirl until combined, about 30-60 seconds.
Step 4: Scrape the batter back into the large bowl. It will be runny. Let the batter stand until thickened to the consistency of oatmeal, about 20 minutes.
Step 5: Preheat oven to 350F. Stir the chopped chocolate into the thickened batter, then divide the batter among the muffin cups.
Step 6: Bake in the center of the oven until the muffins have risen and a toothpick inserted in the center comes out slightly sticky but not wet - about 25-27 minutes.
Step 7: Let muffins cool in the pan for 15 minutes, then transfer to a rack to finish cooling completely.
Step 8: In a small saucepan, combine agave syrup with 2 tbsp. water and vanilla over medium-high heat. Bring to a boil, then remove it from the heat.
Step 9: In the bowl of a stand mixer, beat the egg whites with cream of tartar on high, until soft peaks form, about 1 minute.
Step 10: Slowly pour the hot syrup in a stream down the side of the bowl, beathing until stiff peaks form, about 2-3 minutes more. The frosting should hold it's airy texture.
Step 11: Spread or pipe the frosting onto the muffins. Sprinkle with the grated dark chocolate.
