Yummy birthday cake

A little while ago, I made a birthday cake for someone to have at their “Free Cake Day” party (not wanting to have a Birthday Party, or really celebrate their birthday in general – I know!  How odd.)

I’d recently acquired Rose Beranbaum’s newest cake book (Heavenly Cakes), and wanted to make something from that . I settled on Woody’s Lemon Luxury Layer Cake (page 43), because the lemon flavor seemed bright and cheery, and I hadn’t really done anything interesting with white chocolate in a while.  Plus, I wanted to try out my new transfer sheets.

The cake is a lemon butter cake, baked in two 9″ layers that are split and filled with homemade lemon curd (Rose’s fabulous recipe, that works like a charm and tastes amazingly zingy).

The white chocolate lemon buttercream was the real surprise in this recipe.  The technique Rose calls for is one that I’d never come across before – essentially, you make a white chocolate custard, cool it, beat in butter and then beat until stiff peaks form – and then leave it at room temperature for up to 2 hours until “slightly thickened and spongy”.  Then you beat until smooth, and beat in the lemon curd.

Why the fermentation period?  The buttercream was smooth and creamy and tasty – everything you want – but I can’t quite figure this one out.  It’s easier, overall, than doing either French or Italian buttercream, but you have to have those two hours of downtime.  Does anyone know what’s going on, here?

In any case, the cake and buttercream both came out delicious, I put it all together and decorated with white chocolate shards, and served with either raspberry or blackberry cabernet sorbet.  The not-birthday-boy and his friends/family were highly pleased; very little of this cake was left after the party!  Another hit, Rose.
