I normally bake from scratch but when I saw this pink lemonade cake mix with matching frosting I just had to try them both. This cake can be made two ways: with or without egg yolks. I recommend with as the cake will be nice and moist as a result. This cake would also be just as good with plain white icing or just a dusting of powdered sugar. You can make it as a layer, bundt, or sheet cake, or as cupcakes. I picked it up at the grocery store recently for about $1.80 per box, the frosting was about the same price per can. I ended up going back and purchasing more for later as I believe this is just a seasonal flavor and Pillsbury will pull it from the market at some point. If they do I hope they bring it back every spring. Until then I'll be stocking up.

Ex Output:
Positive

I was excited for these. Got them on a Monday, on Tuesday I came in and my husband tells me you have to try these they are excellent. So I'm like Ok, I reach in the bag and I'm like ewwwww they feel slimey but none the less popped one in my mouth. I almost puked, I spit it right out terrible, disgusting, don't buy these. I love Amazon and buy a ton of stuff from them but these are a definite NO! I might add this was a joke to my husband because he had ate one and had to spit it out! He was just wanting to watch me eat one. :(

I just bought this item, 30-May-09, at my local supermarket for $4.29 per unit. How can it list for over $14.00 and be discounted on your site for over $7.00?
