To get a tall muffin, fill the muffin pan to the very top with batter and start baking your muffins at a higher temperature and then after about five minutes lower the temperature.u003cbr/u003eu003cbr/u003eI start my muffins at 425°F and then lower the temperature to 350°F. Starting at a higher temperature gives the baking soda and baking powder a nice boost of heat that encourages rising.u003cbr/u003eu003cbr/u003eIt also allows the outside of the muffin to set quickly giving the inside the structure it needs to keep rising. This trick will only work with really thick muffin batters that have enough structure to support the muffin.
