It may be true that you cannot make a perfect cupcake using your gut feel on the measurements of the ingredients. There is a need to carefully and properly measure them to come up with fluffiest and yummiest cupcakes. First of all, get all the baking equipment you need from a good, trustworthy store such as http://www.makebake.co.uk/. It is better to measure wet ingredients like water and oil in glass cups. Make sure they are placed on a level surface. For the dry ingredients like such as sugar and flour, nesting cups should be used for measurement. Make sure to level the dry ingredients before putting them to the mixing bowl.
In pouring the cupcake batter, make sure to use an ice cream scoop. If you use a freehand, this may result in cup cakes with different sizes. Sometimes, others may be overcooked, while the rest can be undercooked. Just make sure that you are always consistent with filling each cup in the cupcake pan. Professionals would say it would be good to fill them between 1/2 and 1/3 full. This, of course, depends on the recipe one is using. To make sure that you get the best results, it would be good too to do a trial run for the baking of the cupcakes based on the recipe used. One other important thing in baking cupcakes is the filling. Contrary to the belief that fillings are just for doughnuts, cupcakes can have fillings too. Upon the cooling of the cupcakes, you can use a decorating bag and tip, so that you can put in the filling you want for your cupcakes.
Again, you always need to check your recipe because even the baking times and temperatures may vary for cupcake baking. It will always be based on the recipe. For almost all of the recipes, 350 degrees Fahrenheit (176 degrees Celsius) is the standard and will do fine. If you are using a mini-muffin pan, however, it is important to have the smaller amount of batter, since this just needs less cooking time. Miniature cupcakes only need eight to 10 minutes as opposed to the 18 to 20 minutes for cup cakes in standard size. The bigger the cupcake, the more time it needs to get baked.
