Mix flour, baking powder, salt and sugar in a bowl and set aside. In a large bowl, beat eggs, add milk and mix again. Stir in melted shortening. Add flour mixture all at once and beat until perfectly smooth.

Grease and heat a flat griddle to 325 to 350 degrees. Pour about ¼ cup batter for each pancake. Once bubbles start appearing, add a few blueberries to each pancake. When the pancake edges appear dry, flip. Bake until done. Regrease griddle after 8 to 10 pancakes.
