1teaspooncinnamon (if you really love cinnamon you can add another 1/2 teaspoon)
2apples,peeled, cored, and diced
Preheat a skillet to medium-high heat (275 degrees).
Whisk together the milk and vinegar and allow to rest for 5 minutes.
While milk is curdling, whisk together flour, sugar, baking powder, baking soda, and salt in a large bowl.
Whisk egg and oil into milk. Add wet ingredients to dry ingredients and stir until combined (don't over-mix, it should still have some lumps).
Spray skillet with cooking spray. Use a 1/4 cup measuring cup to pour batter onto skillet. Cook about 2 minutes until bubbles form and the edges start to look "dry". Use a spatula to flip the pancake and cook another 1-2 minutes on the other side. Set pancakes aside and repeat with remaining batter.
Add butter, apples, brown sugar, and cinnamon to a medium sauce pan. Stir over medium heat 3-5 minutes until apples are very tender. Stir in syrup. Serve apple topping over warm pancakes.
