Heat your griddle to medium heat (350°F if it has a temperature.)
Beat the eggs in a large bowl. Add in the milk, oil, and vanilla extract. Whisk ingredients together.
2 large eggs, 2 cups milk, 4 tablespoons vegetable oil, 1 tablepsoon vanilla extract
Combine flour, granulated sugar, baking powder, salt, and cinnamon in a separate bowl.

Add the dry ingredients to the egg mixture. Mix the ingredients together with a rubber spatula or large spoon until you no longer see flour, but do not overmix. The batter should be a medium consistency - not too thin yet not too thick.
Gently fold in the finely diced apples.
