Buttercream is just the best! I had no idea that it can be frozen!
This buttercream frosting looks incredibly delicious!
This is exactly what I need. I am going to make a dessert tomorrow!
You can never go wrong with a good homemade buttercream! 🙂
This frosting was literally the icing on the cake for my daughter’s birthday cupcakes! Perfectly light, fluffy, and delicious!
I love how easy this is to make! So delicious!
Made it yesterday, the best!!!! Not too sweet and so creamy!!!
The recipe was delicious, but it wasn’t as firm as I thought it should have been. I’ll retry tomorrow.
Hi, I am using this recipe for my daughter’s birthday cakes. I am making a sheet cake (9×13) and a round, 2 layer cake. Can you give me an idea of how much frosting this recipe makes? Thank you!
Hi Joelle – This recipe makes enough to frost 18 standard cupcakes. A normal 9×13 sheet cake is equivalent to 24 standard cupcakes. I would triple this recipe in order to frost a sheet cake and 9-inch round double layer cake. You might have a little leftover, but it’s safer to have extra to work with.
Hi. Can you add food coloring to it?
Hi – Yes you can. I prefer the gel food coloring. It’s more concentrated color so it doesn’t affect the consistency of the frosting.
How can I make this recipe more temperature tolerant? Could I had some crisco to help the frosting hold up butter?
Hi Jamie – Yes, butter-flavored shortening may be uses in place of some or all of the butter so help keep it more stable.
This frosting tasted so good, but I wish I had known that it does not harden. I used it on sugar cookies and I have to put them in the refrigerator to get the frosting to harden. Then after I take them out they soften up again.
This is the best buttercream frosting I’ve ever had! I was skeptical at first but it came out perfect.
Hello, I am planning to try this recipe for my next cake, but wanted to inquire about the salt. Is it optional? Only four ingredients are identified in your commentary – butter, confectioners’ sugar, vanilla & milk – so I was surprised when I saw a pinch of salt in the recipe ingredients.
