Brown sugar icing is easy to make and is a perfect with butter cake, chocolate cake, banana cake and more! It comes together in just a few minutes and you can spread it while it is warm for the perfect smooth finish.
This butterscotch icing has all the flavor you would want in a butter brown sugar confection. Spread it over a cake or some yummy pumpkin or apple bars for an out of this world treat.
This penuche icing is no different. It adds that pop of sweetness along with rich brown sugar notes that make it amazing.
The best part is it uses just six simple ingredients. If you are an avid baker, you almost certainly have everything on hand already.
So it likely won’t even require a trip to the grocery store. And you don’t have to wait for your butter to soften, because you are going to melt it anyway.
If first got this recipe back in 2015. One of my coworker’s, Diane, sent it over along with a fun recipe for banana cake.
It instantly became a favorite recipe in my family. And because it was shared only a month into the existence of this website, it quickly became one of the first recipes that other people were making and reporting back.
It is always fun to hear that you enjoyed a recipe that you found here. That is, of course, the reason why I keep on posting them.
In a way, it feels like we are cooking together. And I have the best time cooking with you!
Making the frosting
The beauty of this frosting is how easily it comes together. Just put the milk, brown sugar, and butter in a small saucepan.
Heat it over medium-low heat until the butter is melted and the sugar is dissolved. You don’t want it to boil, this step is just to ensure there is no grainy texture from the brown sugar in the finished icing.
Pour the mixture into a mixer, or just use a hand mixer to stir in the vanilla. Then add the powdered sugar and whip it until it is smooth.
I like to pour it over the cake while it is still a little bit warm. That way it spreads easily and forms a smooth, almost shiny finish.
If you want it to thicken a bit, just keep whipping it until it has come to room temperature. You can even add a little bit more powdered sugar if you want an even thicker consistency.
Just be careful not to make it too sweet. Taste it and add a little more salt to balance it out if you need too.
I mean, really. Just give me a spoon… and a glass of milk… I’m ready to dive in!
