Brown Butter Buttercream -

I've never even heard of brown butter...sorry.
 

i make brown butter buttercream all the time but not a meringue based one...an american buttercream. Everyone LOVES it! It has a deep, rich, almost nutty flavor that pairs really well with banana, spice, pumpkin and apple cakes.

Where does one buy brown butter? are you talking about using brown sugar instead of regular sugar?

I make it also for regular b/c or cream cheese b/c. I make smbc , but i dont,think you could use brown butter. You melt your butter to a lite brown color. Just google , how to make brown butter butter cream or just brown butter. Don,t know if you can buy it, but, i think most people make it. I used it with a banana , chocolate chip cake. It was delicious. All loved it. Again, don,t know if anyone has used it with smbc. I don,t see any recipes using it. I have looked the internet over. hth  You could also p/m FromScratchsf on this site . I think she would know. Or even Leah_s

Does this really make a difference in the taste of the cake?  How many of you people out there brown your butter? Just curious?
 

Browned butter is incredible.  It's not something you buy.  You cook the butter on the stove until it gets to be a golden brown and have a nutty smell.  The milk solids are what turn the butter brown.  It's best to use a stainless steel pot or skillet, as it will be difficult to judge the color of the butter in something with a black or dark non-stick surface.

You can swap browned butter for regular butter.  Obviously, you would want to use it at the same temperature as called for in the recipe.  Even though the moisture might be slightly reduced in the butter after cooking, I have not personally noticed any differences in recipes where it was swapped with regular butter.  In buttercream, browned butter is awesome, especially when used with caramel, pumpkin, or nuts.  I made browned butter pecan pies at Thanksgiving and everyone freaked out about how delicious they were.

It will definitely change the color of your buttercream, but I guess that's not a big deal if you are covering in fondant.
 

I didn,t cover my cake in fondant. It was a banana chocolate chip cake with brown butter cream cheese icing. Delicious!!!! Yes, it changed the color, but the flavor with the banana cake was what it was all about. wish i had a piece now. lol!!!  The recipes for  using it in cake, cupcakes, and icings are all over the internet all on these great decorators blogs. That is where i first learned of it. Glad i was lurking around. Its very popular.
