This sublime flourless cake is my all-time favorite chocolate cake, I return to it again and again. It is dense, supremely moist, tender, and has a little added texture from the ground almonds. It is a not-too-sweet cake, with a perfect balance of butter, toasted almonds and cocoa. Full-flavored yet mellow, it isn't as intense as the Chocolate Oblivion (also Cake Bible). It pairs well with dark ganache spiked with either rum or coffee, or with whipped cream.

For the best flavor, use a full-fat, dutched cocoa, or if you must use a lower-fat cocoa, substitute by weight, 75% low-fat cocoa and 25% chopped unsweetened chocolate (this corrects the cocoa butter content).

For the best texture, use ground almonds that are as fine as possible. If you are grinding them yourself, start with room temperature toasted sliced almonds and grind with some of the sugar from the recipe.

This recipe is a little more time-consuming than some, due to egg whites that are beaten separately and due to the need to toast and grind almonds if you opt not to buy toasted almond flour. But I like it so well I still make it more often than any other cake recipe.

This is a lovely chocolate cake- rich, mellow, and with a finer crumb than the Perfect All-American. The flavor of the chocolate and sour cream remind me of a brownie, though the texture is that of a tender cake.

Although the author prefers serving this cake unadorned, I have found that it also pairs wonderfully with nut flavors. The photo shows this cake baked as cupcakes and topped with hazelnut mousseline (mousseline buttercream with white chocolate and hazelnut paste).

This recipe makes 15 cupcakes and they bake in about 20".

This is a glorious flourless chocolate cake, and it only uses 3 ingredients. Simple and elegant. It really does taste like a chocolate truffle. It's a crowd pleaser and received many compliments.

A Make-Ahead, Sit-Out-All-Night Cake:
I chose this because I could make it a couple of days in advance, and because it could sit out during a party and wouldn't get dry the way a traditional flour- or egg-based cake would. It was still perfectly moist and delicious at the end of the night. However, it is a bit messy to cut if you don't follow the suggestion to use a hot sharp knife.

Chocolate Percentage:
I've made this twice, and used a 53% chocolate one time and 60% the other time. Even though I'm a not-too-sweet person, I found the 60% a little too intense and bitter. I'll stick to 53-57% chocolate for this in the future.

When it's Done:
According to the author, this should bake to an internal temp of 150F, and the water bath should also be about 150F. For me, the water bath worked well when I filled a tea kettle and brought it to a boil while the eggs were beating, then pulled it off the heat and allowed it to cool a bit while I was folding the chocolate/butter mixture and eggs together. Both times I made this, my torte took longer than the specified baking time for the internal temp to come up to 150F.

Hot Fudge Variation:
I also tried the "chocolate torture" variation, with espresso and homemade hot fudge, and have to say that the hot fudge is outstanding and only takes a few minutes to make in the microwave. However, it needs to be quite liquid in order to spread out into a reasonably uniform layer on the cake. Mine was too thick and sunk into the batter in places. Tasted great, but wasn't very pretty.

A second attempt at the hot fudge variation worked well when I used the lukewarm fudge as a topping to pour over the finished, chilled cake. It set up glossy and beautiful at room temp.

The espresso stays in the background and enhances the chocolate, it doesn't come across as a mocha cake.

This buttercream is silky smooth, rich and not too sweet, which means I'll never again suffer through gritty or overly sweet powdered sugar frostings. It's bascially whipped butter lightened with Italian Meringue. It is a little more challenging to make than a powdered sugar frosting, but very worthwhile to master.

There is an updated technique on the author's Youtube video, which basically involves dumping all of the cooled meringue onto the whipped butter at once and then whipping at med-high or high speed. This is much faster and simpler than the tablespoon-at-a-time method in the book, and I've done it several times now, it works well.

An important tip is that this buttercream almost always curdles a little bit just before it forms an emulsion- keep beating on med-high or high and as long as it's at the right temperature it will come together. The ideal temperature for both the whipped butter and the cooled meringue is about 70F.

If the temperature of the buttercream is too cool and it curdles, even badly, it can still be saved by bringing the mixture to the correct temp and then beating on high speed.

Another point is to err on the lower side of the 248-250F for the temperature of the cooked sugar syrup. Going over 250F will produce an overly firm, hard-to-pipe and unpleasant-to-eat buttercream. If the sugar syrup does overshoot 250F, it's easy to swirl in a little water (the temp will lower) and then try for 248F again.

Finally, unsalted butter is a must. Salted butter doesn't taste good in this.

My favorite flavors are the lemon curd and the white chocolate. Normally, I don't care for white chocolate at all, but in this buttercream it doesn't come across as too sweet and it does something incredibly dreamy to the texture.
