Fiona Gallagher. Played by Emmy Rossum. Fiona Gallagher. Fiona is in the difficult position of being the oldest of the Gallagher children, so most of the responsibility and child-rearing falls on her young shoulders. This young woman takes it all in stride -- she's clearly been doing it for a long time.
Take a look at a typical pancake recipe - it tends to ask for eggs and milk, i.e. protein. Pancake mix only needs water, so it will have a higher protein content than normal flower (and is probably flavoured). So you probably can't replace flour with pancake mix in a recipe and expect the same results.
Instead of using butter, substitute canola oil or olive oil. The fat content in the oil will make the resulting cupcakes moister than when you use butter. If your original recipe uses butter, use a ratio of 1 cup butter to 3/4 cup oil to substitute. The science behind this is that oil reduces gluten formation. Gluten is a protein substance found in wheat that binds the baked products together. If they are less bonded, it will result in softer cupcakes.
