Banana Bundt Cake with Penuche Frosting

Quick and easy fun bundt cake to make using up ripe bananas.  What makes it so easy is that it is made from a yellow cake mix.  I was a little intimidated with the idea of making a cooked frosting but it turned out not to be that hard.  It actually went fast.  You just have to work fast and ice the cake while the frosting is still warm.  I sifted the powdered sugar first and put it in the mixing bowl,  Measure out the milk and set aside.  That way I only had to reach for it and keep moving.

It is an impressive cake and great to show off with on special occasions.  You can leave the walnut out if you want.  The frosting really compliments the cake.

    Sounds yummy! Bet it would be good using a spice cake mix, too.

      This was the first time I have made this type of frosting. I think I let it beat just a little too long because it got stiff very quickly. After the cake has been in the cake dish for a couple of days, it even tastes better. The frosting is perfect with a banana cake.

      I think you are right about the spice cake. The frosting is so good and not that hard to make. Like making candy there is a little art to it.

      Thanks for your comment.
