In a large bowl, I whisk together the flour, sugar, cinnamon, baking powder, baking soda and salt until everything is evenly combined. Then I toss in the shredded apple and stir it right into the flour mixture so it doesn't clump together later. This little step keeps the apple shreds distributed evenly through every pancake instead of sinking to the bottom of the bowl.
In a separate bowl, I whisk the apple cider, buttermilk, eggs, oil and vanilla until smooth. I like to do this while the griddle is heating up so everything comes together at once. Getting the wet ingredients fully blended first means I won't need to overmix once they meet the dry ingredients.
I pour the wet mixture into the dry ingredients and stir gently with a wooden spoon, just until combined. The batter should still look a little lumpy, and that's exactly what I want. Overmixing at this stage is the number one way to end up with tough, flat pancakes instead of fluffy ones.
Once my griddle is hot over medium heat, I scoop out ¼ cup portions of batter and pour them on. I let them cook undisturbed until bubbles appear across the surface and the edges look set, then I flip and cook the other side for about two more minutes. I keep finished pancakes under foil on a plate so the whole stack stays warm.
While the pancakes cook, I melt butter in a small skillet and add the chopped apples, stirring often until they're soft but still hold their shape. Then I stir in the brown sugar and cinnamon and let it bubble into a glossy syrup before pulling it off the heat.
Once everything is ready, I spoon the warm cinnamon apples right over the stack of pancakes, letting the syrup drip down the sides. This is the moment I actually can't wait for every single time I make this recipe.
