Ingredients Overview

This cake requires pantry-friendly ingredients, but it’s all about balance — richness from butter and sour cream, deep chocolate from cocoa and real melted chocolate, and a frosting that feels like fudge in frosting form.

For the Cake Layers

• All-purpose flour – Forms the base structure.

• Unsweetened cocoa powder (Dutch-processed preferred) – Intensifies chocolate flavor and gives a dark color.

• Baking soda & baking powder – Ensures a moist, tender crumb with enough lift.

• Salt – Essential to balance the sweetness.

• Granulated sugar + brown sugar – A mix that adds both sweetness and depth.

• Eggs – Help structure the cake and provide richness.

• Sour cream – Adds moisture and a subtle tang.

• Buttermilk – Keeps the crumb ultra-soft.

• Vegetable oil – Makes the cake moist and keeps it soft, even when cold.

• Hot coffee or boiling water – Intensifies chocolate flavor and thins the batter slightly for a silky texture.

For the Chocolate Fudge Frosting

• Unsalted butter – Provides the creamy base.

• Powdered sugar – Sweetens and stabilizes the frosting.

• Cocoa powder – For deep chocolate richness.

• Heavy cream or milk – Smooths the texture.

• Dark chocolate, melted – Makes the frosting ultra-fudgy and glossy.

• Vanilla extract + pinch of salt – To round out and enhance flavor.

Step-by-Step Instructions

This cake involves baking rich layers and whipping up a luscious frosting. It’s a classic build — no tricks, just the good stuff.

Step 1: Make the Cake Layers

1. Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.

2. In a large bowl, sift together:

   • 1¾ cups all-purpose flour

   • ¾ cup cocoa powder

   • 1½ tsp baking soda

   • 1½ tsp baking powder

   • ½ tsp salt

3. In another bowl, beat:

   • 1 cup granulated sugar

   • ½ cup brown sugar

   • 2 large eggs

   • ¾ cup sour cream

   • ½ cup vegetable oil

   • 1 tsp vanilla extract

4. Stir in ¾ cup buttermilk.

5. Slowly add dry ingredients to wet, mixing until just combined.

6. Stir in ½ cup hot coffee (or hot water). Batter will be thin — that’s good!

7. Divide evenly into pans and bake for 30–35 minutes, or until a toothpick comes out with a few moist crumbs.

8. Cool in pans 10 minutes, then transfer to wire racks. Chill cakes in the fridge if frosting later.

Step 2: Make the Fudge Frosting

1. In a large bowl, beat 1 cup unsalted butter (room temp) until creamy.

2. Add:

   • ¾ cup cocoa powder

   • 3½ cups powdered sugar (in batches)

   • ½ tsp salt

3. Mix in:

   • 1 tsp vanilla extract

   • ½ cup heavy cream (adjust to preferred consistency)

4. Fold in 4 oz melted dark chocolate (cooled slightly) for an ultra-fudgy texture.

5. Beat for another 1–2 minutes until smooth and glossy.

Step 3: Assemble the Cake

1. Level the cake layers if domed. Place the first layer on a cake stand or plate.

2. Spread a generous layer of frosting. Top with the second cake layer.

3. Frost the top and sides with remaining frosting.

4. For the full Matilda look, use an offset spatula to create soft swirls or leave the frosting thick and rustic.

Optional: Top with chocolate curls, shavings, or a light sprinkle of sea salt.

• Fold chocolate chips or chopped chocolate into the batter for extra gooeyness.

• Use Nutella or peanut butter between layers for a twist.

Dietary Modifications

FAQs

Q1: Why is it called “Matilda Chocolate Cake”?

It’s inspired by the infamous chocolate cake scene in Matilda, where Bruce Bogtrotter is forced to eat a massive chocolate cake in front of his classmates. It’s since become the gold standard for over-the-top chocolate cakes.

Q2: Can I make this cake ahead of time?

Yes! Bake and cool the cake layers, then wrap and refrigerate for up to 2 days. Frost the day you plan to serve it. You can also freeze the cake (unfrosted) for up to 2 months.

Q3: Can I make this cake as cupcakes?

Absolutely. The batter yields about 24 cupcakes. Fill liners ¾ full and bake at 350°F for 18–20 minutes.

Q4: How do I store the cake?

Keep it covered at room temperature for up to 2 days, or refrigerate for up to 5 days. Let it come to room temp before serving for the best texture.

Q5: Can I use milk chocolate instead of dark?

Yes, but reduce the added sugar slightly in the frosting — milk chocolate is sweeter. It will give the cake a lighter, creamier flavor.

Q6: What’s the texture like?

This cake is moist, rich, and dense, but not heavy. The frosting is smooth and fudgy — somewhere between ganache and buttercream.

Q7: How do I get perfectly clean slices?

Chill the cake for at least 1 hour before slicing, and use a sharp knife dipped in hot water. Wipe between each cut.
