Here are a few tricks you can try when making any muffin recipe: -Don't overmix your ingredients. You should combine the wet and dry ingredients until just incorporated and nothing more. -Use room-temperature ingredients. The milk, eggs, and butter should all be at room temperature for a light and fluffy batter. -Let them cool. Remove the muffins from the tin right out of the oven and allow them to cool on a baking rack for 5 minutes. This will allow the air to circulate around the entire muffin.
