Bruce Bogtrotter’s Chocolate Cake

Recently, when filling out an application for a food-writing job, I was asked to name my favorite food writers. I began to compile a list of the obvious suspects—Ruth Reichl, Laurie Colwin, MFK Fisher, Gabrielle Hamilton, all of whom I love and admire—but I simply could not get Roald Dahl out of my head. Sure, he isn’t actually a “food writer” but his books were what first made me fall in love with food descriptions. Dahl writes about food from a child’s perspective, with no pretension and none of the weird adult anxieties about food that come with growing old.


To his characters food is still exciting and overwhelming, powerful, visceral, spell-binding, rich. Food is used as a weapon, reward, healing agent and instrument of destruction. Think the peach in James and the Giant Peach, Willy Wonka’s chocolate factory, Mr. Twit’s food-filled beard, snozzcumbers in The BFG, and of course, the enormous chocolate cake that the Trunchbull forces poor Bruce Bogtrotter to eat in Matilda. I never heard back from that food writing job—shocking, I know—but what I did get out of answering that question was a very real and nagging hankering for a chocolate cake the size of my torso.


I am lucky enough to live right down the street from a real life chocolate factory, and one that, in my opinion, gives Willy Wonka’s some serious competition. This undying need for the richest, chocolatiest cake imaginable gave me a good excuse (and trust me, I am always looking for a good excuse) to go and visit The Mast Brothers Chocolate Factory and pick up some chocolate.

If you aren’t familiar with the Mast Brothers the video below will give you some background. A little warning before you watch: you will feel devastated that you aren’t one of them.

Now, back to Bogtrotter.

I feel a kindred connection with poor Brucie, a slave to chocolate cravings so all-encompassing he will even risk the wrath of a principal who has “a lock-up cupboard in her private quarters called The Chokey” (104). An all-school assembly is held and Bruce is called up onto the stage, where the Trunchbull announces to everyone that he “sneaked in like a serpent into the kitchen and stole a slice of my private chocolate cake from my tea-tray! That tray had just been prepared for me personally by the cook! It was my morning snack! And as for the cake, it was my own private stock! That was not boy’s cake! You don’t think for one minute I’m going to eat the filth I give to you? That cake was made from real butter and real cream! And he, that robber-bandit, that safe-cracker, that highwayman standing over there with his socks around his ankles stole it and ate it!” (120).

Then, in a move wholly unexpected, the Trunchbull has her cook bring to the stage  “an enormous round chocolate cake on a china platter. The cake was fully eighteen inches in diameter and it was covered with dark-brown chocolate icing” (124).


She then tells him that he will eat the entire cake right there, and quickly, because “Greedy little thieves who like to eat cake must have cake!” (128). The whole school watches in horror, waiting for Bruce to be sick, or beg for mercy, or be hauled off to the Chokey, but to everyone’s surprise he keeps on “pushing the stuff into his mouth with the dogged perseverance of a long-distance runner who has sighted the finishing-line and knows he must keep going” until “the very last mouthful disappeared” (131).


It is a moment of victory for children and chocolate addicts alike, and one that I still get immense pleasure out of. Only the densest cake would do for Bruce so I subbed sour cream where I would usually use buttermilk, omitted baking powder, and added espresso powder to make the chocolate flavors even more intense. The chocolate frosting got sour cream too, as a nod to Trunchbull’s poor cook who “looked as though her mouth was full of lemon juice” (124).


Bruce Bogtrotter’s Chocolate cake

Makes 1 triple layer cake (I doubled this)


  • 3 cups brown sugar, packed
  • 1 cup of soft butter
  • 4 eggs
  • 2 teaspoons good vanilla extract
  • 2 2/3 cups AP flour
  • ¾ cup cocoa powder
  • 1 tablespoon baking soda
  • ½ teaspoon salt
  • 1 1/3 cup sour cream
  • 1 1/3 cup boiling water
  • 1 tablespoon instant espresso powder


Chocolate Sour Cream Frosting:

  • ½ cup softened butter
  • 6 ounces of good quality semi-sweet chocolate
  • 5 cups confectioner’s sugar
  • 1 cup sour cream
  • 2 teaspoons good vanilla



In a mixing bowl, cream brown sugar and butter. Add eggs and beat on high speed until light and fluffy. Blend in vanilla. Combine flour, cocoa, baking soda and salt; add alternately with sour cream to creamed mixture. Mix on low just until combined. Add espresso powder to hot water and add to batter until blended. Pour into three greased and floured 9-in. round baking pans. Bake at 350 for 35 minutes. Cool in pans 10 minutes; remove to wire racks to cool completely. For frosting, in a medium saucepan, melt butter and chocolate over low heat. Cool several minutes. In a mixing bowl, combine sugar, sour cream and vanilla. Add chocolate mixture and beat until smooth.

SOUR CREAM? INSTANT ESPRESSO POWDER? Cara, you’ve returned with some serious power. BRAVO. DO NOT STOP NOW.

Oh Matilda!! How we loved reading that book together! And of course who could ever forget the unlikely hero Bruce Bogtrotter?! The chocolate cake you baked is exactly the one I picture him eating in the book…but you added so much panache to Trunchbull’s (“much too good for children”) most likely basic confection. The chocolate from the Mast Brothers and the espresso powder… genius.
Also, I love the new look of the site!! Keep cooking/baking/writing/reading- we are all the better for it!!
So when will you bake this for me?!

You are so talented! I love the way you write and your pictures are beautiful. Any plans to write a cookbook? I’d be the first in line at Barnes and Noble! Keep up the amazing work.
a big fan,

I remember when I was young, Gary Rhodes did a childrens cookery program based around the stories of roald dahl’s revolting recipes, he presented it inside a giant peach. The sad thing is I can’t find any of this on the internet other than his cookery book… I think we need to bring it back… and I think you should be the new presenter! yey for dahl!

I have the revolting recipes books but we definitely didn’t have that program here in the states–I wish we had! If you ever find a clip let me know, I would love to see Gary Rhodes inside of a giant peach. Thanks for reading, Amy, love your blog!

Love it! I am looking at your blog with my 3 year old daughter. She loves all your pictures. You are very talented in so many ways.

The next time you pop into the Mast Brothers shop, please ask them if they need an apprentice. I can’t decide which one is cuter. Seriously.

Isn’t it torturous? I think I would pay them to work there, just to bask in their handsomeness

Brilliant blog! I’ve linked to you today from my Roald Dahl Day post :)

WOW!!! my favorite story and my favorite food!!! I cant handle this.


Kate May 14, 2015 at 12:56 pm

I made this for my daughter’s 9th birthday bc she is a huge Matilda fan. We are going to see the musical next week for her birthday. I thought it was very fitting to make this for her birthday cake. The moment I lifted the cake lid she knew it was Bruce’s cake. She devoured it so fast it would have made Bruce proud. I am keeping this recipe as a favorite. Amazing cake!
