One word - DELICIOUS.
A few more words --- This tastes just like I remember. You need very few ingredients, although, it's tough to see just how much butter goes in here! We also made a homemade buttercream (bag of confectionary sugar, more butter, vanilla, a bit of milk) and it turned out great! Super moist, flavorful, not crumbly or dry. WOW - I'm impressed Betty Crocker.
I still need to try the cookies, brownies and vanilla cake -- all of which I've read mixed reviews.
