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.

We are into our third can of this flavorful and easy mix and it just seems to get better and better! Sunday is pancake day at our house, and today we had blueberry pancakes with real maple syrup. This mix holds fresh blueberries nicely - don't over-mix the ingredients and you will get nice, fluffy fruit-filled (or not) pancakes that are absolutely first-rate.

This is ridiculous. The best gourmet ketchup I have ever tasted. It is pricey, but wow..love this stuff. It would make a great gift for someone who is hard to buy for but loves their ketchup. Yummy!
