    I've made this recipe several times, and it has turned out perfectly every time. It is luscious, so creamy, and not overly sweet. This is so much better than standard buttercream which can form a crust, and can be too sweet. I am perplexed by other reviewers who found fault with the directions; they seemed straightforward. The only problem is that I have to rely on testing the sugar as it forms the soft ball, because it reaches that stage long before my candy thermometer reaches 238 degrees. I have added lemon juice and zest to make an amazing lemon frosting, and raspberry reduction to make a beautiful raspberry frosting. This frosting can be flavored a number of ways. This is a generous recipe that easily frosts a 3 layer 9 inch cake. Everyone raves over this frosting. It's a winner!

    I made this recipe and loved it!!! The only thing is that my cakes are filled with fillings that need to be refrigerated and when this icing is refrigerated it gets so hard like butter.. Any suggestions??

      It's supposed to get hard, as it's buttercream! If you make it ahead of icing your cakes, then give it about a 30-45 minutes sitting out at room temperature, and I give it a whip through again. If the cake is all done, then just take it out, the same amount of time, to come to room temperature. If you're going to decorate, it's a lot easier when it is hard and cold. This is what I've made since pastry and baking school and everyone loves it, even non-cake eaters. It's versatile and easy!

    This is my go-to buttercream that I also add different flavors to (white chocolate, coconut extract, strawberries, etc). I usually find that I need about 3/4 Lb of butter instead of the whole pound. I usually add a dash of salt as well. I find this is an easier method of making buttercream than swiss meringue. Anyway, thanks marthastewart.com.

      Hi! I made this icing and love it! Except I filled my cake with Canoli filling which needs to be refrigerated but the buttercream hardens in the refrigerator.. Any suggestions or just use a different filling that does not need to refrigerated?

    I followed this recipe exactly as written and had zero problems. My niece, a pastry chef, directed me to this recipe (she informed me that Martha's recipes are 'tight'). The only change I made, upon her suggestion, was to use a vanilla bean in lieu of vanilla extract. My husband - not a frosting fan - did not push any aside. I will use this recipe again for sure!

    I live in a very hot climate, but this recipe does work! After adding the butter, it did not hold any shape at all. I refrigerated the IMBC (in its mixing bowl) then took it out and whipped it (using a paddle attachment) and the frosting just came together! It took a few minutes - like whipping cold cream. After frosting the cake, I kept it in the fridge. The frosting held up the whole time it was being served and stayed out of the ref!

    Your directions suck butt! Please do yourself a favor: if you are not a Bakery Chef, please find other directions or you will either drive yourself mad or never bake again. Thanks for nothing Martha Stewart

    Don't refrigerate this. The butter will separate into their separate components of water, milk fats etc. That's why it weeps. It is good at room temperature for 3 days.
