  I LOVE frosting.  As far as I am concerned, most of the time cake is mostly just an excuse for frosting.  I have had a particular crush for cooked frostings lately.  

There is something magic that happens when you cook milk and flour to a paste and then whip it into butter or cream cheese and make it into something so light and airy and so good.

     So I just knew I was going to love this caramel-y butterscotch frosting recipe Di sent.  I adjusted it slightly because I didn’t have any heavy cream and I wasn’t in the mood to go to the store.  It was still wonderful!

   Di sent this as the recommended topping for her now famous banana cake.  Since the banana cake requires a trip to the freezer, I just beat until the frosting is mixed but still warm.

    Then I pour the frosting on the cake fresh from the freezer.  You just pour and spread.  The frosting sets quickly on the frozen cake.

    Then set it aside and let it come to room temp.  You will never have a more moist and delicious banana cake in your life and the frosting is a perfect consistency too!

     If you are frosting a room temperature cake, just beat the frosting a little longer.  As it cools down it will become a spreadable consistency.

I mean, really.  Just give me a spoon… and a glass of milk… this frosting is a sweet one!

I love cooked frostings, they are so much lighter than normal frostings. I will be trying this one for sure, yum! :-)

I love cooked frosting too! But I love pretty much any kid of frosting, so it's a low bar!

You know I am a frosting girl too, not to mention loving Carmel so I'm sure this will be my favorite frosting of all!

It's a good one! I love that the cake I use it on is frozen so I can just pour it on while it is still warm and give it a quick spread and call it a day! I hope you're surviving ok, Andrea! I'm sure he'll do wonderful!
