Granola - In a medium bowl add the brown sugar, oats, chopped nuts, and cinnamon mix together. Add the melted butter to the dry ingredients and mix well. Set aside.

Muffins - Preheat oven to 375 degrees F. Sift together the flour, sugar, baking soda, and salt. To this mixture mix in the chocolate chips. In another bowl mix the 1/2 cup melted butter, milk, eggs, and vanilla. Pour the milk mixture into the dry mixture and mix just until blended. Line muffin tins with paper cups and fill about 3/4 of the cup. Top with the granola mixture and with fingers press the granola lightly into the dough. Bake for 17 to 19 minutes until the muffins are lightly brown. Place on cooling racks for 2 or 3 minutes and remove the muffins from tins and set on cooling racks and cool completely.
