Pumpkin Chocolate Chip Muffins

1/2 cup melted butter
2 eggs
1 cup pumpkin
1 Tbsp. pumpkin spice
1 cup sugar
1 tsp. baking soda
1/4 tsp. baking powder
1/4 tsp. salt
1 2/3 cup flour
1 cup chocolate chips (I use semi sweet, but you can use milk chocolate also)

Mix together wet ingredients. Combine dry ingredients in a separate bowl. Then fold in the dry combination until wet. Place dough into muffin tins. Cook on 350 for 20-25 minutes.
