To a blender, add the flour, cottage cheese, sweet potatoes, oil, eggs, cinnamon, salt, and 1 tbsp water. Blend until smooth. If batter is too thick, add another 1 tbsp water and blend.
Coat a 12-inch nonstick skillet with the cooking spray and heat on medium. Add the batter, ¼ cup at a time, to form pancakes and cook 1–2 min., until edges begin to set and bubbles start to form.
Flip pancakes and cook another 1 min., until bottoms are golden brown. Repeat with remaining batter. Serve with the Greek yogurt, mixed berries, honey, and coconut flakes, if desired.
