Preheat oven to 350°F. Line two cookie sheets with parchment paper.
Thoroughly combine flour blend, brown sugar, baking powder, baking soda and cinnamon in a large bowl. Cut in butter until mixture resembles coarse meal.
In a separate bowl, beat eggs, yogurt and vanilla for 1 minute. Add to dry ingredients and beat until smooth. Fold in blueberries and cereal.
Scoop dough onto prepared cookie sheets, leaving about 1 inch between each. Use plastic wrap to gently press and smooth cookies into ½ inch-thick disks. Brush with yogurt and sprinkle with brown sugar.
Place in preheated oven and bake 19 to 20 minutes until done. Serve warm.
