Preheat oven to 400-degrees F. Grease muffin tins; set aside.
In a medium mixing bowl, mix the cereal and milk together. Set aside for 10 minutes to allow cereal to absorb the milk.
Add the eggs, coconut oil, honey and vanilla extract; stir until well blended. Stir in the chopped apple.
In a large mixing bowl, whisk together the flour, baking powder, cinnamon, baking soda and salt. Add the chopped dates. If the dates are fresh, they will likely be quite sticky. With clean hands, toss the dates with the flour mixture, breaking up the date pieces that are sticking together.
Add the wet ingredients and the pecans to the dry ingredients. Stir just until combined. Over-mixing will result in tough muffins with tunnels.
Fill prepared muffin tin(s) 3/4 full. A 3 tablespoon scoop, slightly over filled with batter, works well. Bake for 15-18 minutes or until a toothpick inserted in center of several muffins comes out clean. Watch the muffins carefully during the baking process. Do not over-cook them because it will result in dry, tough muffins. Suggestion: Every oven bakes differently. Check the muffins at the 14 minute mark. If the toothpick comes out very wet with batter, bake muffins for an additional 2 minutes and re-check. However, if the muffins test only a little bit wet, bake for an additional 1 minute and re-check.
Remove muffins from pan(s) and cool on cooling rack. When cool, either wrap individually in plastic wrap or place several muffins together in plastic bags. Store in refrigerator or freezer.
