This chocolate swirl walnut pound cake made me look back these past years.

A few years ago I ventured into the gastronomic business with a small café, something you probably know if you come here often. I closed it (sold it) a few months ago, have absolutely no regrets whatsoever of any shape, size or form, just in case you’re thinking how sad, and got my life back.

Gastronomy.
It’s a hard life, which you hear about endlessly, and yet nothing compares to reality. Especially when you dive into it with another job going on and not a drop of experience. Molly of Orangette, brilliantly explains the feeling ‘A couple of years ago, not long after we opened Delancey, back in the days when I was still cooking there every night and trying to write on the side and living on pizza and cookie dough and adrenaline and contemplating a third career as a mass murderer, ..’

Now that I have more time, and before it magically disappears again, for whatever reason, I decided to start investigating certain things I had on my mind for the longest time, like nut pastes and creams. I am very familiar with the well known frangipane (almond cream), a mixture of almonds, sugar and eggs mainly, and an extraordinary base for fruit tarts, like pears, peaches, plums, figs, or apples as in this crackly apple almond tart.

The almond paste is the first step when making almond cream, where the nuts are ground with powdered sugar and a binding ingredient is added, in my case egg whites, though I’ve made it with honey and corn syrup too.

I often wondered why other nuts where not used as often as almonds. I mean, pistachios, hazelnuts, walnuts, all marvelous flavors to use in fruit tarts. Or as is the case here, in a gooey, tender walnut chocolate pound cake.

So, taking matters into my own hands, I made a walnut cream and used it in this cake, where it is treated almost as a butter and then swirled with chocolate, before a crumble is added on top. Simply wonderful.

This is a pound cake with a texture unlike a regular pound cake. It is more buttery, not so doughy. Any nut goes well with chocolate, so feel free to change the flavor.
The crumble is a nice and crunchy surprise, which might seem too much, but it works.

Being this a very rich cake, if you have to feed many people, it’s a good idea to bake it in square form, and cut it in smaller pieces. Or serve it with coffee after a meal for a perfect sweet bite to end the night.

Just checking that only 1/4 cup of cane sugar is the correct amount. I know there is sugar in the walnut paste that is added to the cake, but just wanted to confirm the measurement.

  Yes June, only 1/4 cup. The rest is provided by the overly sweet walnut paste.

As a kid I loved Sara Lee chocolate swirl pound cake which was taken off the market, then returned and taken off again.The chocolate was distinct and you could really taste the swirls. It also had almond extract. Your pictures look pretty convincing that I might be able to nearly replicate the swirl experience. One question- the cake call for 1/4 cup of sugar- is that correct? I realize the the walnut paste has 1 cup of confectionery sugar but I just wanted to confirm the sugar measurement before trying the recipe. Thanks

OMG, Paula! This looks absolutely incredible! I am very familiar with Nancy Silverton's wonderful recipes…I've made her bran muffins on my blog, and they are the best ever, so I'm positive this is no different!
