Everyone remembers the scene. Bruce Bogtrotter, a whole school watching, and a chocolate cake the size of a car tire. I rewatched the film with my nephew last winter and he asked whether that cake was real, which is how this Matilda cake started.
This Matilda cake recipe gives you three dark, damp layers held together with a thick fudge frosting. Nothing fancy, nothing tempered, nothing that needs a piping bag. The whole point is excess, so the frosting goes on in swirls rather than smooth.
Below the recipe I’ve covered what actually keeps the crumb this moist. There’s also a cooked fudge frosting variation, plus a decorating section aimed at birthdays and anniversaries.

Why You’ll Love This Recipe
The batter is a whisk job. Dry ingredients in one bowl, wet in another, hot coffee stirred in last. No creaming butter, which means no waiting for anything to reach room temperature.
Three layers do the heavy lifting. Each gap gets a thick spread of frosting, so every slice hits the same ratio the film cake had, which is roughly half cake and half chocolate.
It also survives being made ahead. The layers freeze well and the frosted cake sits happily in the fridge overnight, which matters when you’re making a Matilda cake at home for a party the next day.
Matilda Cake Ingredients & Substitutions
Two things do most of the work here: Dutch-process cocoa for color and hot coffee for depth. The coffee won’t make the cake taste like coffee. It just makes the chocolate read darker.
| Ingredients | Amount | Substitution or Note |
| All-purpose flour | 2 cups (250 g) | Spoon and level it |
| Granulated sugar | 2 cups (400 g) | Don’t reduce it, it holds moisture |
| Dutch-process cocoa | ¾ cup (75 g) | Natural cocoa gives a lighter color |
| Baking powder | 2 teaspoons | Check the date |
| Baking soda | 1½ teaspoons | Works with the buttermilk |
| Salt | 1 teaspoon | Balances all that sugar |
| Buttermilk | 1 cup (240 ml) | Milk plus 1 tbsp vinegar |
| Vegetable oil | ½ cup (120 ml) | Melted coconut oil |
| Large eggs | 2 | Room temperature |
| Vanilla extract | 2 teaspoons | Optional but worth it |
| Hot coffee | 1 cup (240 ml) | Boiling water works too |
| Butter for frosting | 1 cup (226 g) | Softened, not melted |
| Cocoa for frosting | ¾ cup (75 g) | Sift it first |
| Powdered sugar | 4 cups (480 g) | Sifted |
| Dark chocolate | 8 oz (226 g) | Melted and cooled |
| Heavy cream | ½ cup (120 ml) | Add slowly |
- Oil keeps the crumb damp for days. Butter cakes firm up in the fridge, and this one needs to survive a night under heavy frosting.
- Buttermilk softens the crumb and reacts with the baking soda. Its acidity is also what stops the cocoa tasting flat.
- Hot coffee blooms the cocoa, which deepens the flavor and the color at the same time. Boiling water does the same job slightly less well.
- Melted chocolate in the frosting is what separates fudge from plain buttercream. Cocoa alone gives you color without that dense, glossy set.
- Heavy cream loosens the frosting enough to swirl. Add it a tablespoon at a time, because too much and the swirls collapse.
How To Make a Matilda Cake
Step 1: Prep the Pans
- Heat the oven to 350°F, grease three 8-inch round pans, and line the bottoms with parchment circles.
- Dust the greased sides with cocoa rather than flour, so you don’t get white streaks on a dark cake.
Step 2: Whisk the Dry Ingredients
- Whisk the flour, sugar, cocoa, baking powder, baking soda, and salt in a large bowl.
- Keep going until the cocoa is fully mixed in, since lumps of dry cocoa stay bitter after baking.
Step 3: Add the Wet Ingredients
- Pour in the buttermilk, oil, eggs, and vanilla, then mix on medium speed for about two minutes.
- Stir in the hot coffee last and expect a very thin batter, which is exactly what you want.
Step 4: Bake and Cool
- Divide the batter evenly between the three pans, weighing them if you have a scale.
- Bake for 28 to 32 minutes, until a skewer comes out with a few damp crumbs rather than wet batter.
- Cool in the pans 10 minutes, turn out, and leave until completely cold before frosting.
Step 5: Make the Fudge Frosting
- Beat the softened butter for two minutes, then add the sifted cocoa and powdered sugar in stages.
- Pour in the cooled melted chocolate, the vanilla, and a pinch of salt, and beat until glossy.
- Add cream a tablespoon at a time until the frosting holds a peak but still falls off a spoon slowly.
Step 6: Stack and Swirl
- Level the domed tops with a serrated knife, then stack the layers with a generous cup of frosting between each.
- Cover the top and sides thickly, then drag the back of a spoon through it to make deep swirls.
- Chill the cake for 30 minutes so the slices hold their shape when you cut them.
Super Moist Chocolate Cake Recipe
People ask why this crumb stays damp when their usual bake dries out by day two. A super moist chocolate cake recipe almost always comes down to the same handful of choices, not to one secret ingredient.
What Keeps It Moist
- Oil instead of butter, since oil stays liquid at room temperature and butter sets firm.
- A high sugar ratio, because sugar holds on to water in the crumb rather than releasing it.
- Buttermilk or sour cream for acidity, which tenderizes the gluten strands.
- A thin batter, which sounds wrong but bakes into a softer, more tender crumb.
The other half is the baking itself. Pull the layers when a skewer still shows damp crumbs, because carryover heat finishes them off in the pan. An extra four minutes in the oven turns a moist cake dry, and no frosting hides that.
Chocolate Fudge Cake
If you want something denser than buttercream can give you, turn this into a proper chocolate fudge cake with a cooked frosting. It sets firmer, slices cleaner, and tastes closer to the glossy icing in the film.
Cooked Fudge Frosting
- Whisk 50 g cocoa, 30 g cornstarch, 280 g sugar, and a pinch of salt in a saucepan.
- Add 335 ml cold milk gradually, whisking until there are no lumps at all.
- Cook over medium heat, stirring constantly, until it thickens like a pudding.
- Take it off the heat, stir in 135 g chopped dark chocolate until melted, and cool before using.
This frosting thickens as it cools, so spread it while it’s still slightly warm. Once it sets, it holds the swirls firmly, which is why cut slices keep their shape on the plate instead of slumping sideways after an hour.
Matilda Cake Decoration
A Matilda cake isn’t meant to look neat, and copying it badly is the whole point. Good Matilda cake decoration means thick, uneven swirls and a glossy surface rather than sharp edges and a scraped finish.
How to Get the Look
- Use the back of a spoon in big sweeping arcs rather than an offset spatula.
- Keep the frosting thicker on top than on the sides, which is how the screen cake reads.
- Add a ring of maraschino cherries around the top edge, as in the musical version.
- Skip the drip, the sprinkles, and the piped borders entirely, since neatness fights the theme.
Serve it with cold milk in a glass jug if you’re photographing it. That single detail does more for the reference than any amount of decoration on the cake itself, and it costs you nothing beyond a clean jug.
Matilda Cake for Birthdays and Anniversaries
A birthday Matilda cake works for any age, which is unusual. Kids know the scene from the musical, and adults know the 1996 film, so the same cake lands at a seventh birthday and a fortieth.
- For an anniversary Matilda cake, bake it in two 6-inch pans instead for a taller, smaller cake that serves eight.
- Write names in white chocolate on a parchment sheet, chill them firm, and set them on top.
- A Leon and Matilda cake, or any two names sharing one party, works best with the names on a topper rather than piped into the frosting.
- Halve the recipe for cupcakes and finish each one with a single cherry.
Keep the portion size honest. Three 8-inch layers under this much frosting cuts into 16 rich slices, and most people won’t finish theirs, whatever Bruce Bogtrotter managed on screen.
Pro Tips
- Sift the cocoa for the frosting. Unsifted cocoa leaves gritty specks that you’ll feel in every bite.
- Freeze the layers for an hour before stacking. Cold layers barely shed crumbs, which keeps the frosting clean and dark.
- Keep a jug of hot water nearby and warm your knife between slices. It cuts through set fudge frosting without dragging.
- Store the cake covered in the fridge for up to 5 days, but let a slice sit out for 30 minutes first. Cold fudge frosting tastes dull.
- Bake the layers up to a month ahead if you’re planning. Wrap each one twice in plastic, freeze flat, and thaw them in the wrapping so the condensation stays outside.
Wrapping Up
Bake it a day ahead if your schedule allows. The layers settle, the frosting firms up overnight, and the whole thing slices far more cleanly than it ever does fresh from the oven.
A Matilda cake is supposed to look like too much of a good thing. Pile the frosting on, swirl it roughly with a spoon, and let it be the excessive thing it was written to be.
