They were then all mixed thoroughly with a different spoon to ensure that no more or less baking powder went into another bowl. The bottom of the cupcake tins were marked to ensure that the right mixture was placed in the right tin and measured correctly. The mixture of each bowl was poured to 3 quarters of the corresponding cupcake tin. The mixture filled two cupcake tins to the correct height and half of the third row of cupcake tins. The third cupcake tins were used for observations against each other. The cupcakes were then placed in a fan-forced oven at 180 degrees to bake for 17minutes. At five minute intervals observe the cupcakes to see if there is any difference in the
