In a large mixing bowl, whisk together 1 cup of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon of ground cinnamon, a pinch of ground nutmeg, ¼ teaspoon of salt, and 2 tablespoons of granulated sugar until well blended.

In a separate bowl, crack 1 large egg and whisk it lightly. Then, add 1 cup of milk, 2 tablespoons of melted unsalted butter, and 1 teaspoon of vanilla extract. Mix until fully combined and smooth.

Pour the wet mixture directly into the bowl with the dry ingredients. Using a spatula, gently fold the mixtures together until just combined.

Take 1 medium apple, peel it if desired, and chop it into small pieces or grate it. Fold the diced apples into the pancake batter.

Allow the pancake batter to rest for about 5-10 minutes.

Preheat a lightly oiled griddle or skillet over medium heat, about 350°F (175°C). Test if the surface is ready.

Using a measuring cup, pour ¼ cup of batter onto the heated griddle for each pancake.

Cook the pancakes on the first side for about 2-3 minutes or until you see bubbles forming.

Carefully flip the pancakes and cook for an additional 2-3 minutes, or until they turn golden brown.

If you're making multiple batches, keep the finished pancakes warm by placing them in a low oven set at 200°F (93°C).
