The pox on you guy, I'm a diabetic since last year.
Yeah, my wife is fighting it too.
But and occasional splurge can be budgeted for in your daily carbs, unless you are really out of control.
And little tricks, like for the mug cake, swap Splenda for the sugar, and divide it into small ramekins or demi-tasse (obviously change the cooking time).
Pancakes, make 'em silver dollar size and forgo the glaze on them.
