04 - Pour whole milk into the wet ingredient mixture and stir well until fully incorporated.
05 - Add wet ingredients to dry ingredients and gently fold until just combined; do not overmix to maintain tender texture.
06 - Gently fold in peeled, diced apples until evenly distributed throughout the batter.
07 - Divide batter evenly among prepared muffin cups, filling each about three-quarters full.
08 - Mix granulated sugar with ground cinnamon in a small bowl, then sprinkle the blend over the top of each muffin.
09 - Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
10 - Allow muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving.
