Kristin of Fat Girl Cakes tells us the story behind her cake:

“Every year, after Christmas I start working on some new display cakes for the upcoming bridal shows I attend.  I used to only bring fondant displays because they traveled better, held up longer, etc.  Of course about 80% of my cakes, both wedding and special occasion cakes, are iced in buttercream, so I felt like I wasn’t showing off much of what I actually do.  On top of that, I feel like the bridal world is starting to feature more buttercream-iced cakes, so I set out to do a buttercream display to really showcase the different buttercream techniques and textures.

When I started designing the cake, I knew I wanted to alternate heavy textures with some “lighter” tiers for balance.  Balance is big thing with me as my degree is in mathematics, and yes, I know it doesn’t need to be that way for everyone, but I need it to be!  I wasn’t sure all the textures would work together, but I figured it was worth giving it a shot.

My original plan was to make it all white, but in trying to add a little violet gel to whiten my icing, I added a little too much.  Instead of starting over, I decided to just go with it and make it ombre instead.  It ended up working out great as it was a real eye-catcher at the shows.  Hopefully this year I will get to step outside of the traditional smooth and rustic buttercream cakes, and start doing some interesting combinations of the fun techniques we have been seeing a lot lately.”

Kristin of Fat Girl Cakes tells us about her technique:

“The base tier was done with a large rose petal tip, just wiggling it up and down while spinning the tier on the turntable. I love the large ruffle look the tip gives without using fondant. The middle tier was the rosette technique you see all over the place. I did this one with the 2D tip instead of the 1M tip, just to see if there was a difference in the way it turned out.  The top tier was done using a large round tip, making dots, smearing them across the cake and then piping the next row of dots over the end of the smear.

The two plainer tiers were done using a #3 tip and doing various drop lines.  I just added a little bit of corn syrup to thin out the buttercream and add a little elasticity.”

Not that buttercream cakes ever ‘went away’…. but today’s feature is a gorgeous example of ‘the new’ buttercream cake.  Modern buttercream style at it’s best.  Full of texture, elegance and delicious details.  I think buttercream may just have a new outlook on life.

    Absolutely beautiful!! Can someone please post a buttercream frosting that holds up to be able to do these techniques. I have tried with my recipe and it always starts to melt/droop.. any help on to what I am doing wrong would be great. I always use all butter in my recipe, is that my problem? Thanks

    Did you decorate each cake by itself, than stack or the other way around? Making something similar for my sister’s birthday Saturday.
