Today I made a gâteau opéra to take to dinner with Allen's parents. I used The Splendid Table's recipe, which was excellent. A few notes on the recipe:
- The cakes should bake seven minutes exactly, at least in my oven.
- I needed about two tablespoons extra butter (to total two cups) in order for my buttercream to set up.
- It helps to switch to the paddle attachment when you add the butter to the buttercream.
- The cake is meant to be decorated with the word "opéra" and a piece of edible gold leaf, but alas, my pantry wants for gold leaf. To make the "opéra,"print out the word in whatever font you like (mine was sized 130 pt for a five by ten-inch cake), and cut out the letters, making sure to leave paper connecting the "holes" in the o, p, e, and a. Place your stencil over your cake, and sift dutch-process cocoa powder or confectioner's sugar over it.
