Trail Mix Muffins

I changed up my favorite blueberry muffin recipe tonight and made some "Trail Mix Muffins." Except they're not really trail mix-ey. I always think of trail mix as having peanuts and fake m&ms, and I really really don't like trail mix. But, I couldn't come up with a better name, so Trail Mix Muffins it is. I bought some walnut pieces and dried cranberry and pomegrantes the other day, and I thought they would make excellent muffins together. And they do!!
Trail Mix Muffins

1/2 c butter or margarine
1 1/4 c white sugar
1/2 tsp salt
2 eggs
1 3/4 c flour
2 tsp baking powder
1/2 c buttermilk *
nuts, dried fruit, fresh fruit, or whatever else you like in Trail Mix
2 Tbsp Turbinado sugar

Preheat oven to 375. Spray muffin tin with Pam or other nonstick baking spray (or use paper liners). In a large bowl cream together butter, sugar, and salt. Stir in eggs one at a time. In another bowl, mix flour and baking powder. Stir dry ingredients into egg mixture, alternating with the buttermilk. Stir just until mixed. Fold in nuts/fruits/other items. Fill muffin cups almost to the tops, and sprinkle a little Turbinado sugar on top. Bake approximately 30 minutes or until golden brown.

* I don't ever have buttermilk and never remember to buy it, so I make my own. To make one cup buttermilk, pour 1 Tbsp white vinegar into a 1 cup measuring cup and fill the rest of the way with regular milk (whole milk preferably).
