Preheat oven to 350 degrees. In a large bowl, combine dry ingredients, except nut mix. In a separate bowl, combine all the wet ingredients. Stir the wet ingredients into the dry ingredients and mix very well. Fill each muffin tin about 1/3 with oatmeal mixture. Divide 1/2 the nut mixture between each muffin cup. Fill the cups with the remainder of the oatmeal. Sprinkle each muffin with the other half of the nut mixture. Gently press each with the back of a spoon. This helps ensure it sticks to the muffins as it bakes. Bake for 30 minutes until liquid is absorbed.
