This looks like a knock0ff of Kate's cake in the The Great British Baking Show (Season 5). I like Kate's use of thin layers of a simple white sponge cake better than the crepes. She also created the caramel sugared nuts with the spikes for her cake.

I had no problems with the recipe- thank you previous commentors for your tips!- I have to say though that the cake wasn't nearly as high as the one pictured. I did use an 8" pan, so it's unclear to me why this would be.

The cake was much richer than I like but it went over well with everyone else. I had issues making my hazelnut cream and it was a little thinner than I had planned so as the 30+ crepes took shape it did begin to slowly slide so I put wooden skewers in it to hold it while it set in the refrigerator. Keep in mind this is not a big cake, it will be about 8 inches wide (given an 8in crepe pan and probably about 6 inches tall. I took two days making it, 1 for prep and chilling and 1 for finishing.

Also, when I look at the picture it seems like there is probably twice as much cream between the layers as what mine looked like (I used the 3 Tablespoons called for). For it to look like that cake I would probably have to have doubled the cream.

I made this for a dessert contest and won overall. For awhile though while making it I was ready to give up--it takes a long time to make and crepes aren't easy. I like to make the chocolate crepe recipe by itself... it'd be good with strawberries. Couple things.... I didn't have the hazelnut cream -whatever that is exactly- but I used part hazelnut coffee creamer and part ground-up hazelnuts. It worked really well; I food-processed the hazelnuts very fine. I halved the chocolate glaze recipe.

P.S. there is also a recipe for hazelnut cream here, that I think would work. http://www.marthastewart.com/355331/hazelnut-cream-tuiles The hazelnut cream that I found was simply sweetened nut butter. Be sure you are not using hazelnut coffee creamer, that is not what they are talking about.

This cake is epic, but it truly does take forever. I had no problems with stability, I am guessing those who did, did not whip the filling long enough after adding the butter. It is Swiss meringue buttercream, so after adding butter, it will get soupy, so whip the heck out of it until it's thick and fluffy again...it will be perfectly stable between the crepes if you do this. I also chilled my crepes before assembling. I made my own hazelnut cream in the food processor. It's just nut butter.

My third attempt to make this cake was this weekend, and it finally turned out perfect! I've had stability problems in the past as well, but this time I refrigerated the crepes until they were cold. Also, since we don't like hazelnut much, I used nutella chocolate creme or raspberry chocolate creme (found in the peanut butter aisle) instead and raspberry extract instead of vanilla (to cover up the faint hazelnut taste in the nutella) in the filling. It turns out amazing.

This was obnoxiously delicious!!!! Pure food pornography. ;-) I was a little nervous starting out as I read all the reviews about the stability of the cake but we had no trouble whatsoever. It did take about 8.5 hours of labor to pull it off however, so plan ahead! I think the most important part is to use actual hazelnut creme. I found it at Williams and Sonoma. I wasn't familiar with it prior, but it is basically the equivalent of the filling you find in a hazelnut creme filled chocolate.

I also had trouble with this cake's stability. Next time I will: whip the cream more to make it firmer, refrigerate the filling before using, and assembling the crepes in 4 stacks, then refigerating overnight, combine the stacks, and refigerate 30 min. That should do it, else just make a cake base and rod in the center to stack them on! Would also double the recipe of filling if you want to look like the pic. Instead of hazelnut cream/butter I used ground hazelnuts.
