Quadruple Chocolate Loaf Cake

by amy on 13 November 2013

Quadruple Chocolate Loaf CakeI’m just going to dive in + tell y’all, this cake is AMAZING. First, let me explain the name – it’s called a Quadruple Chocolate Cake because it has 4 different sources of chocolate – a chocolate-based cake, with chocolate morsels mixed throughout, topped with a cocoa syrup, + even more flaked chocolate on top of that. SWOON. I first ate this cake a few months back, when my friend Alexandra made it for a girls’ night party. It was one of the most chocolatey, rich, decadent cakes I’d ever eaten + I couldn’t stop going back for more bites.

So, when my chocolate-loving husband had a birthday last week + he requested, simply, “something really chocolatey” for his birthday dessert, I knew I had to give this cake a try. And surprisingly, it was really easy to make, coming together quickly + easily. The end result is a super rich, sticky, sweet, perfectly chocolatey loaf cake. It is amazing for dessert, topped with ice cream + hot sauce, or as a mid-afternoon pick-me-up, with a cup of tea. And if you love chocolate as much as we do, you *must* put it on your to-make-soon list – you will love it!

Quadruple Chocolate Loaf Cake

Quadruple Chocolate Loaf Cake

serves 8-10, adapted from Nigella Lawson

Ingredients

1 2/3 cups all-purpose flour
1/2 teaspoon baking soda
1/2 cup unsweetened cocoa
1 1/2 cups superfine sugar
1 1/2 sticks soft unsalted butter
2 large eggs
1 tablespoon vanilla extract
1/3 cup sour cream
1/2 cup boiling water
1 cup bittersweet chocolate chips

For the syrup:
1 teaspoon unsweetened cocoa
1/2 cup water
1/2 cup superfine sugar
1 oz bittersweet chocolate (from a thick bar)

Directions

Take whatever you need out of the fridge so that all ingredients can come to room temperature.

Preheat the oven to gas mark 325 degrees F, putting in a baking sheet as you do so, and line a 2lb loaf tin (mine measures 9.5″ x 4.5″ x 3″ deep and the cooking times are based on that) with greased foil – making sure there are no tears – and leave an overhang all round. Or use a silicon tin.

Put the flour, baking soda, cocoa, sugar, butter, eggs, vanilla + sour cream into the processor and process till a smooth, satiny brown batter. Scrape down with a rubber spatula and process again while pouring the boiling water down the funnel. Switch it off then remove the lid and the well-scraped double-bladed knife and, still using your rubber spatula, stir in the chocolate chips or morsels.

Scrape and pour this beautiful batter into the prepared loaf tin and slide into the oven, cooking for about 1 hour. When it’s ready, the loaf will be risen and split down the middle and a cake-tester, or a fine skewer, will pretty well come out clean. But this is a damp cake so don’t be alarmed at a bit of stickiness in evidence; rather, greet it.

Not long before the cake is due out of the oven – say when it’s had about 45-50 minutes – put the syrup ingredients of cocoa, water and sugar into a small saucepan and boil for 5 minutes. You may find it needs a little longer: what you want is a reduced liquid, that’s to say a syrup, though I often take it a little further, so that the sugar caramelizes and the syrup has a really dark, smokey chocolate intensity.

Take the cake out of the oven and sit it on a cooling rack and, still in its tin, pierce here and there with a cake tester. Then pour the syrup as evenly as possible, which is not very, over the surface of the cake. It will run to the sides of the tin, but some will have been absorbed in the middle.

Let the cake become completely cold and then slip out of its tin, removing the foil as you do so. Sit on an oblong or other plate. Now take your bar of chocolate, wrapped in foil if you haven’t got much of its wrapper left, and cut with a heavy sharp knife, so that it splinters and flakes and falls in slices of varying thickness and thinness.

I’ve specified a weight for the chocolate flakes, but really go by eye: when you think you’ve got enough to scatter over the top of the loafcake, stop slicing. Sprinkle these chocolate splinters over the top of the sticky surface of the cake.

How embarrassing that I didn’t even recognize this cake! I remember, now, making it. But your riff [and photos]? DEEEEEELICIOUS. Imma have to recreate *this* very recipe next time. Looks, so so good!

I can’t believe you didn’t remember this – it was sooooo amazing! I think it was for one of our girls’ nights (maybe a Bachelor/Bachelorette viewing party?) so you had made lots of other distracting noms, too. But this is the one that stuck with me! Of course, I was a crazy sweets-obsessed pregnant lady at that point. =)

You cannot go wrong with chocolate in my mind. Adding for kinds to one baked good is right up my alley! Lovely!

5 Stephanie @ Plain Chicken November 13, 2013 at 8:31 am

WOW! I am in chocolate heaven! :)

6 Maggie @ A Bitchin' Kitchen November 13, 2013 at 9:09 am

As a full blown chocolaholic, this recipe is calling my name.

my kind of cake! I love what sour cream does in cake batter too! Definitely pulling this out next time I need a chocolate fix!

12 Mimi @ Culinary Couture November 13, 2013 at 1:23 pm

There is absolutely nothing better than chocolate on top of chocolate on top of chocolate on top of chocolate. This is my dream cake!

wow, I love how much chocolate goodness is in here! it looks and sounds incredible! my chocolate lover hubby would be over the moon if i made this for him – thanks for sharing Amy and can’t wait to try this :)

23 Adri November 14, 2013 at 9:33 am

Wow! A glass of Prosecco, and I’m in! This looks great. Years ago, and I do mean MANY years ago, a dear friend asked me if I had ever found a good recipe for what was essentially a chocolate pound cake. Over time, she and I tried many recipes. They were all either too heavy, too sweet, not chocolatey enough – you get the picture. This one, with the addition of sour cream and the use of cocoa and chips, coupled with the chocolate is, I bet, the answer. Thanks!

24 amy November 14, 2013 at 9:44 am

That is awesome, Adri! I hope you and/or your friend try it, and find that it’s just the cake you’ve been looking for! And I agree – a glass of prosecco would be pure perfection with this. =)

25 Lesley Eats November 14, 2013 at 12:34 pm

I’m having a touch of chocolate-induced arrythmia just looking at the pics. Wow!

26 Beth November 14, 2013 at 1:14 pm

That cake looks unbelievable! Next time I’m looking for a chocolate overload, I’ll know where to start.

27 Tara @ Chip Chip Hooray November 14, 2013 at 2:17 pm

Yup, it’s official…I would call this a quickbread so I could eat it for breakfast. ;)

28 sarah k @ the pajama chef November 14, 2013 at 2:46 pm

whoa, 4 kinds of chocolate?! i definitely need to give this cake a go! yum!

29 Luv What You Do November 14, 2013 at 9:49 pm

This looks fantastic! I love quick breads and haven’t made a chocolate one in forever!

Quadruple chocolate?! I’m in heaven! I can have this for breakfast, lunch and dinner. A big glass of milk is a must. ;) Have a great week Amy!
