Yes, just put the mix into a cake tin instead of into muffin cases.
Not much other than muffins... One big muffin?
yes if you get a gluten free muffin mix
You'll have fudge in a muffin tin, it won't be a fudge muffin.
12 muffins in one tray, unless you have a really big muffin tray then it's different. :D
Usually it just serves as the molder and the means of which you can hold the muffin when you eat it. It also prevents the batter to stick to the muffin molder. It also affects the look of the muffin.
It is not necessarily the kind of flour as it is how much you BEAT IT. Muffins should never be beaten. You beat the eggs, etc but once you get to adding the flour, it needs to be GENTLY folded in. The more you mix it, the tougher the batter becomes. Then you have a cake rather than a muffin.
Yes, spicy muffins do exist. Anyone can make spicy muffins by adding spices to the muffin mix. One spice that is good for some added heat is cayenne pepper spice.
yes. If you want to end up with corn bread/muffins, yes.
How many muffins you'd get from a one pound package of muffin mix, depends on how big your muffin pans are. The package should say what the expected yield would be if you use a standard size muffin tin that aren't over filled.
It's available at Amazon.
Overstirring most any batter mix (muffins, cake, cookies, ect.) can cause it to come out wrong. This is especially true in muffins. When you mix the batter, usually it is to incorportae all the ingredients together. If you mix it after the components are already combined, you begin to alter certain ingredients. Stirring can create minor amounts of heat, which can begin to cook eggs or cause milk to gather a different taste. Mixing can also eliminate needed air pockets, or whip the batter to be too light and airy.
I'm sure that you can otherwise you just have raw cake mix? If you mean reheating it after its cooked, I find that a quick short microwave blitz will help freshen the muffin.
