After much googling and comparing, I put together my own recipe based on the basic similarities of other mug cake recipes (mostly chocolate ones, blah) that I found.
It took me a couple of tries to get this one just to my liking, so I hope you enjoy it too!
mix all dry ingredients together
add all wet ingredients and mix
add nuts now if you want them, or chocolate chips if you prefer
microwave on HALF POWER for 3 min
(my first round was on full power and I ended up with a super dense rubbery cake...ick!)
