Pumpkin Chocolate Chunk Muffins

Hi guys! I'm almost fall, so it's time for a new recipe...And what would make more sense than a Pumpkin recipe???  I stumbled upon this recipe from PumpkinRecipes.org a while back and I accidentally made this healthier by omitting the melted butter. Who knew, they still tasted great, so I'm sticking with it!

1-1/2 C. flour
1/2 C. sugar
2 tsp. baking powder
1/2 tsp. cinnamon
1/2 tsp. salt
1 C. milk
1/2 C. pumpkin puree
1 egg
3/4 C. chocolate chunks
1/3 C. chopped walnuts

Preheat oven to 400 degrees. Combine the dry ingredients in a large bowl. In another medium sized bowl, whisk together the milk, pumpkin, and egg. Add the wet mixture to the dry ingredients. Barely stir together, then add in chocolate chunks. Try to not over stir the batter and allow for visible pockets of flour. Fill muffin cups 2/3 full. Top with chopped nuts. Bake 15-18 minutes until slightly golden.
