Baking
Muffins should be baked in the center of a preheated oven and are done when a toothpick inserted in the center comes out clean and the edges start to come away from the sides of the pan, usually 20-25 minutes at a 350° - 400°F (175° - 205°C) oven.
Spoon the muffin batter into the muffin tin using two spoons or a disher.Only fill each cup 1/2 to 2/3 full. Even during this step, handle the batter as little as possible as too much handling will cause a tough muffin. Fill any unused cups halfway with water to prevent over browning of the muffins or warping of the pan. Turn the pan halfway during baking for even browning. Make sure you do not overbake muffins or they will be dry. When done, remove from oven and place on a wire rack to cool slightly (5-10 minutes) before removing from pan.
