I watched the Next Great Baker which is a competition show with the Cake Boss guy.

Also Sweet Genius

and Top Chef: Just Desserts.

It's more like which ones DON'T I watch! Any cake or cupcake show I can find, I record. I watch the three you have listed plus Cupcake Wars, Cake Boss (who's new season starts Monday), D.C Cupcakes. Two shows I can't seem to find anymore is Amazing Wedding Cakes & Have Cake, Will Travel. Amazing Wedding Cakes was my favorite & I picked up a lot of tips & ideas from the designers. Also Ace of Cakes but is that even on anymore?

Cupcake Wars
Cake Boss

Those are about it lol

If Cupcake wars is the one where they start with 4 contestants and in the end the last two remaining have to make huge displays of about 1000 cupcakes I've watched a few of those.

I'm in Ireland and we have Food Network channel on digital and I watch every cake show I can (except Ace of Cakes as I can't stand Duff!)

Cake Boss
Cake Boss Next Great Baker
Amazing Cakes
Staten Island Cakes
DC Cupcakes
Cupcake Girls
Cupcake Wars
Fabulous Cakes
Just Desserts with Anne Thornton

and I'm sure I'm forgetting a few more...

Top Chef Just Desserts- I like all the Top Chef franchises but this one is my favorite.

Sweet Genius- Ron Ben-Israel's on air presence was much better in the second season, it's obvious people from Food Network are working with him.

The Next Great Baker- like a train wreck to me...I hate it but watch it anyway.

I miss Challenge, it was my favorite. I liked duff and his crew, too. I'm over Cake Boss and not really into the cupcake shows although I've watched Cupcake Wars a few times.

I tried to watch sweet genius... Just because I love Ron Ben Israel... The show sucks.... I thought he would do a cake show and share his talent with the world... I was wrong... I want Ron to do cakes and flowers.... Anyone else feel the same way...
