  1. Preheat oven to 400F/205C and heavily grease a 12 cup standard muffin pan.
  2. In a medium bowl mix together flour, quick oats, sugars, baking powder, cinnamon, cloves, allspice, nutmeg, and salt. Set aside.
  3. In a large bowl mix together eggs, sour cream, milk, oil, and vanilla. Slowly mix in dry ingredients, just until no flour streaks remain. Fold in apple chunks.

Streusel Topping

  1. To make streusel topping in a medium bowl mix flour, brown sugar, butter, oats, a pinch of cinnamon, nutmeg and cloves. Use clean fingers to rub the butter in to the dry streusel ingredients. You want clumps of streusel. 
  2. Fill muffin pans all the way to the top with batter. Sprinkle streusel on top. Bake for 5 minutes then reduce the temperature to 350F/180C and bake for an addition 13- 15 minutes. Until a toothpick inserted in comes out clean. Place on wire rack to cool.

Maple Glaze

  1. In a small bowl mix together powdered sugar, maple syrup, maple extract and hot water. If too thick add a teaspoon of water at a time to reach desired consistency. Drizzle on top of muffins. Best eaten on the day they are made, but leftovers can be stored in an air-tight container for up to 3 days.
