2.5 ounce portion of white store bought cake with yep, the sickly sweet buttercream frosting..it came from Kroger if it matters. Thanks! p.s. it was good but I don't want anymore for some time!

According to this, 1/8 of a sheet is 280.

Actually, that's for 1/12th of a 1/8 sheet cake. A full sheet cake is HUGE - like what you see at some parties - so they are commonly sold as quarter-sheets or even eighth-sheets. So 1/12th of a 1/8th sheet is basically a normal-sized piece of cake.

I am guessing it was a lot of calories too--I am marking 400 to be sure.

Oh yeah, that's what I meant.

I just had the same was wondering what to mark. Ours came from jewel bake shop. Im gonna go with 400 as well since I had a 2x2 inch piece and I know those huge Costco buttercream frosted muffins are like 800 apiece so this serving of cake seems to be about half than one of those or a litl less than half. 1/4 sheet cake serves 22 people 2x2 or 16 people if the slices are 2x3 according to most cake sites. I dont find calories anywhere though and I guess it would vary greatly depending on how much of the frosting. 220 sounds more like for JUST the cake alone with no frosting and I think thats what some sites mean when listing this amount per serving. Im gonna go with 1/2 a costco buttercream iced muffin cuz I know what I had wasnt worse than that and those things are piled high with the frosting like crazy. I just comment here in case anyone else gets curious like me for an exact figure or something to put down on our journals since most dont list any nutritional information and only list the ingredients. Costco has some enormously high caloric stuff and extremely large not even possible to eat portions of things but one thing I do find is that u can pretty much always find the caloric content of their stuff online on one of the food log sites and it can be a good judge or gage for guessing at other stuff sometimes for those of us who really just GOTTA have some kinda number or something comparable to log on our journals.

chances are the frostings from the store were made with shortening, and not butter. That might help you in figuring out the calories.

I lost all concentration just at the sight of the word "buttercream"

I'm not kidding.

Vex: I haven't had cake and frosting in so long I can't even remember what it tastes like. But I do have a brand new Yankee Candle in the Buttercream scent and I'm afraid I might take out a spoon to try and eat it, it smells so good.

I have a great cupcake recipe. 4 ingredients. 110 calories with frosting.

Box of cake mix. Don't follow directions on the box. Mix the cake mix with a 12 oz can of sprite zero (any diet soda will work really but u won't taste the sprite. Put approx 1/4 cup of the mix in each cupcake paper and bake 20 mins at 350°.
Cool completely.
Frosting: don't follow directions on the pudding box. Just mix small box of instant sugar free pudding mix with fat free cool whip (8oz)

You'll love them! You're welcome.

(try chocolate cake, chocolate pudding frosting, and use diet cherry vanilla dr pepper in the cake. Top each cupcake with a maraschino cherry. Great for Valentines!

Also, diet cream soda is harder to find but works really good. Might help with the buttercream craving.
