No one was more surprised that I when a <gasp!> mix I bought from our local kosher store <gasp! again!> turned out to not only "suffice until I can get around to my baking - after all, my husband will eat almost anything chocolate regardless of pedigree. Our store had the hadar cake mixes on sales from $3.89 to 99 cents a box - maybe they were lasts years, maybe they are being discontinued, I have no idea.
I added coffee chocolate chips to the chocolate cake and frosted it with a mocha icing I made. I only added cinnamon to the nut cake, and, to the coffee cake I added some thinly sliced apples. There are certain cakes I make every year (mocha brownies!) and sadly some I don't (no one could bake all year round like my mother-in-law A"H, and especially for Passover - I'll never have the likes of her sponge cake again, so far as I can tell or have tried.)
I would use these cakes in the future if they continue to produce them. I'm going to increase the amount of apples I used with the crumb cake mx and make an apple kugel for during Yom Tov.
Again, who knew?
Matzoh and butter - I don't have much of either during the year and can't WAIT for Passover in order to indulge. Love it. I'm fortunate in that I have none of the "stereotypical" problems others have with matzoh.
