Combine flour, baking powder, salt, and milk, mixing well.
Add in the sugar, eggs, and vanilla. Continue mixing until well combined.
Fold in the blueberries, blackberries, and strawberries.
Heat a griddle or skillet to medium heat and spray with non-stick cooking spray.
Spoon out the batter into about sand dollar size and let it cook on one side until the batter begins to bubble, then flip over and cook until done. This typically just takes 2-3 minutes. It should release fairly easily from the griddle and you can be sure that the bottom is browned.
Continue until all pancake batter is used.
Warm up the maple syrup and add a little butter on the pancakes along with warm syrup plus a few more berries.
