Welcome Autumn Rosette Cake

 Simple rosette cake to welcome the first day of autumn.  

With cookies too.

The hardest part of this cake was mixing the colors.  I mixed the colors based on a Pretty Autumn Color Palette blog post by Sweet SugarBelle.  The darker colors in the piping bag (the orange and brown) look like they are separating a bit, but the icing on the cake looked okay.  I'm not sure why some of the colors separate like this.  I have read that it happens when you put too much gel color in the buttercream, but I'm not positive.  Maybe it was the heat, maybe it was the humidity.  The first day of fall calendar-wise does not mean the temperature won't reach 90 degrees F.

So any buttercream experts have any tips to keep this from happening???  

 

Happy Decorating,
