Baking with B: Lucy’s Chocolate Chocolate Cake



Somehow (somehow!) I was roped into making a birthday cake for one of the office staff.

Okay. So it wasn’t really that hard to convince me. And when my co-worker Lucy requested that her cake could be anything that was “chocolate chocolate” (that is, chocolate cake with chocolate icing), I was totally game.

And don’t even try to tell me that it should be “double chocolate”. She asked for “chocolate chocolate” and I think I delivered.

2 oz./55g semisweet chocolate, chopped

2 tbsp milk

1 1/2 c. all-purpose flour

1 tbsp baking powder

3/4 c. unsalted butter, softened

generous 1/4 c. dark brown sugar

3 eggs, beaten

1 tsp vanilla extract

Filling and Frosting

31/2 oz./100 g semisweet chocolate, chopped

4 tbsp unsalted butter, softened

1 1/2 c. icing sugar

1 tsp vanilla extract

1 tbsp milk

Preheat the oven to 350F. Grease a 9-inch round cake pan and line with parchment paper.

First, take a picture of the chopped chocolate and post it on Instagram just to be a huge tease. When you’re done gloating about how many likes your picture got (you’re welcome), gently heat the chocolate and milk in a saucepan just until melted, without boiling. Remove from heat.

Sift the flour and baking powder together and add the butter, brown sugar, eggs and vanilla extract. Beat well until smooth, then stir in the melted chocolate mixture.

Spoon the batter into pan smooth level. Bake for 50-60 minutes, or until firm to the touch and just beginning to shrink away from the sides of the pan.

Let cool in the pan for 10 minutes, then turn out onto wire racks to finish cooling. When cold, carefully slice the cake horizontally into 2 layers.

B’s Tip: For the love of all that is good, please test all your willpower and do not try to cut the cake before it has cooled! I learned that the hard way- my first round of this cake got totally smooshed.

For the filling and frosting, melt the chocolate with the butter in a small pan over low heat. Remove from the heat and stir in the confectioner’s sugar, vanilla extract, and milk, then beat well until smooth.

Sandwich the cake layers together with half the chocolate mixture, then spread the remainder on top of the cake, swirling with a spatula. Sprinkle with leftover grated chocolate, if desired.

I substituted milk with cream with no difficulties (so sue me, I was all out!) and instead of a layered option I used the extra icing to frosting the sides of the cake as well. The result? A rich, chocolatey cake with a dense, moist texture. It keeps in the fridge wonderfully if you’re making it ahead of time- just remember to cover with tin foil and let rest at room temperature a few minutes before serving.

Lucy said that it was everything she wanted and the rest of the office seemed pleased as punch, too. Considering my first stab at this recipe turned out a disaster, I was pretty happy with the results too. I’m definitely not waiting until Lucy’s next birthday to try this cake again!

Happy baking!
