This is from allrecipes.com - pretty tasty! I put my changes in bold type:
- Preheat oven to 350 degrees F (175 degrees C). Lightly grease 12 muffin cups.
- In a large bowl, combine flour, baking powder, salt, cinnamon and nutmeg. In a separate bowl, beat together oil, sugar, egg and milk. Stir egg mixture into flour mixture, just until moistened. Spoon batter into prepared muffin cups.
- Bake in preheated oven for 15-20 minutes, until a toothpick inserted into a muffin comes out clean.
- While muffins are baking, make cinnamon sugar (we have a shaker of it in our spice rack). While muffins are still hot, dip tops in melted butter and then in cinnamon sugar mixture. I brushed the tops with butter and sprinkled the cinnamon sugar on them.
