The best way to ensure you will not have lumps is to start with the flour in a sauce pan over medium heat and very slowly pour in the milk, whisking the entire time. Also, so as not to get that gritty taste, I added the sugar to the flour mixture just before taking it off the heat. I then let the entire mixture cool in the fridge before whipping it into the butter. It turned out perfectly!


This was a wonderful recipe. After I cooled the milk and flour mixture I beat it with the mixer until it was creamy and then added the rest of the ingredients. The frosting came out light and creamy like whipped cream, but better. I made a second batch and added melted semi sweet chocolate and a ½ cup more of powder sugar . It was perfect every one raved over the frosting on both of my cakes.


Oh, my.. this is amazing frosting. I've made classic egg-based buttercreams before, but always found them too buttery. And I'm not a fan of powdered sugar/butter/shortening frostings personally. This recipe was the perfect medium between the egg-based and American buttercreams: incredibly silky texture, not too sweet, nice and buttery but without tasting like sweetened butter (I've tried this recipe both as written and using all butter, and I actually prefer it as written). The only things I would recommend specifically are: 1) Use a stand mixer; 2) Cream your butter, shortening, and sugar together for at least 5 minutes before adding the milk mixture; 3) Add a pinch of salt; 4) After adding the milk mixture, beat the frosting for at least 5-10 minutes to give the sugar crystals time to dissolve, otherwise you'll have gritty frosting.
