    This WAS unbelievably good! I used yellow cake mix, Blackberry Fusion and Raspberry jello (cause that's what was in my pantry!) along with a 12-oz package of frozen blackberries and four large, fresh strawberries. The recipe yielded 12 cupcakes (about 20 min.) and a large loaf (about 35 min.). A couple of things that I was unsure about in the recipe: the fruit was to be "unthawed" but that didn't make sense, so I thawed them by running warm water over the bag. Also, I wasn't sure if I was supposed to use my electric mixer to blend the fruit in the batter or just stir them in...but I did use the mixer and it turned out GREAT. Thanks for the delicious recipe!

    This is a wonderful cake. I used raspberry-blackberry fusion jello. Not sure if they still make it..Also I added a little Raspberry syrup to the cream cheese frosting. This is one recipe I will definately make again, but I think I will use a little more cream chese in the frosting. it was a little soft.

    This cake had great flavor however it sunk in the middle once out of the oven.

    Very, Very moist, very, very good. Everyone loved it. I used sugar free geletin (raspberry) and added 1 cup of fresh strawberries with the fresh blackberries. Definately a keeper.
