I bought a pkt mix (I never buy pkts & make all cakes etc from scratch) But at NQR I saw a pkt of Betty Crockers White Choc Chip muffins.
So I grabbed them & on the side it said for a variation add raspberries or blueberries...

So I grabbed a pkt of frozen raspberries (worked out cheaper than the fresh ones)
I added 1.5 cups to the Pkt mix (made as per pkt) & cooked & OMG, these are DELICIOUS!!!!!

I went back & grabbed 2 more pkts & served some up for our dinner party on Saturday night & my BIL (whom is a chef) said they were so delicious & asked for my recipe, so I snuck away & made a hamper for him... I popped a spare box of muffins & the frozen raspberries ina basket for him with a wooden spoon!!! Noone could believe it was a pkt (as I am renowned for me cakes etc)

SO EASY!!!!!
