My All-Vegetable Shortening Buttercream Did Not Crust Even With A 1:1 Ratio

Hi Everyone,

Typically I use  1 cup butter and 1 cup vegetable shortening (crisco container and measured out in a cup) and 2 lbs powdered sugar and my buttercream crusts just fine.

Yesterday, I didn't have butter so I ended up using just the crisco vegetable shortening from the container and measured out 2 cups, and used 2 lbs powdered sugar, but it didn't crust.

Anyone know if I need to use more powdered sugar if it's just an all vegetable shortening buttercream? did I not measure it out correctly maybe?

Thanks!

All shortening icing doesn’t really crust. Shortening in it’s natural state is soft, so it won’t harden/crust,  unlike butter which is hard in it’s natural state. The only way a all shortening icing will crust is with an addition of either a couple of tablespoons of meringue powder, or 1/4-1cup of royal icing.

When I want crusting b'cream icing I reduce the shortening to sugar.  If you used only 1 1/2 C Crisco to 2#s of sugar it would crust -- at least some.    Read about it in these recipes:  https://www.cakecentral.com/recipe/22469/2-icing       https://www.cakecentral.com/recipe/7445/the-original-wasc-cake-recipe  (at the bottom of this long post)

You can use Dream Whip when you want the frosting to crust.  This was in the wilton frosting recipe I learned with in the 70's. (I'm getting a little on the old side!)

I am happy to see this thread because I recently had a similar experience.  Since my frosting needed to be white, I used all Crisco.  I added a ton of extra sugar making the icing very stiff, but it still didn't crust worth a hoot.  As long as it was in the fridge, it had a slight crust, but almost melted as soon as I brought it our of the refrigerator.  I had a heck of a time even frosting the cake.  I've never had this happen before, so I am blaming it on the new regulations on shortening with zero transfats.  I usually use butter, but am glad to see the recommendations for making it more firm, in the event I must use all shortening again.

I’m wondering if they have made more changes very recently   I never had such problems   It’s been months since I’ve made icing— like close to a year I guess but even w-the original removal of the  trans fat I didn’t think there was any major difference in my icing especially w-it crusting

Well meringue powder/royal icing is definitely your friend in this scenario!!

kakeladi, I was thinking the same thing.  The Crisco I am buying now does not seem to work at all like the Crisco I used before I learned about high ratio shortening.  Since the transfats have been removed, I just went back to Crisco.
