Epic Failure! Anyone know what I did wrong?

So, the ginger cupcakes (on the left) turned out great (post/recipe to come later today/tomorrow) but my vanilla recipe (on the right) I did by totally making it up as I was going along turned out to be an epic failure.  Must add, they tasted oh so yummy - but caved and did not rise.  I used 1 tsp each of B. powder and B. Soda - pinch of salt, flours, egg, buttermilk, butter and vanilla.

Any ideas???

OK, so I think perhaps baking while on muscle relaxers and painkillers is not such a great idea ;-)   I did the same ones again and they turned out brilliant.  I must have either did something twice or forgot something??  Anyway, here are the 2nd batch - can not wait for them to cool so I can decorate!!!!
