How to Make This Fudgy Chocolate Cake

Make the Cake Layers

Preheat oven to 350°F. Grease and line three 9-inch cake pans or cake tins with parchment paper.
In a large mixing bowl, whisk together all dry ingredients: sugar, flour, cocoa powder, espresso powder, baking soda, baking powder, and salt.
Add eggs, buttermilk, sour cream, oil, and vanilla. Mix using a hand mixer or bowl of a stand mixer with paddle attachment on medium speed until smooth.
Slowly pour in the boiling water while mixing on low speed. The chocolate cake batter will be thin.
Divide evenly between pans and bake 28-32 minutes. Use a toothpick to test for doneness.
Cool for 10 minutes, then remove the cakes from the pans and cool completely on a wire rack.

Make the Cake Soak

Combine water, cocoa powder, sugar, and vanilla in a saucepan over medium heat. Stir with a wooden spoon just until sugar dissolves. Cool before using.

Make the Chocolate Frosting

Beat softened butter in a large bowl until creamy.
Mix in cocoa powder, then slowly alternate adding powdered sugar and milk.
Add vanilla extract and beat on medium-high speed until fluffy frosting forms. Adjust with more milk for spreading consistency.

Assemble the Cake

Place the first cake layer on a cake stand or serving plate.
Brush the top with a few spoonfuls of cake soak.
Spread a thick layer of chocolate frosting on top.
Repeat with remaining layers, using soak and frosting between each.
Frost the outside of the cake and smooth with a spatula or cake scraper.
Allow the cake to sit for 30 minutes before digging in.

Quick Tips for the Perfect Chocolate Cake

Use boiling water or hot coffee to bloom the cocoa for a richer, darker color and deeper flavor.
Let your room temperature eggs and dairy blend more easily for smooth batter.
For the best chocolate cake, don't skip the cake soak-it makes a big difference in moisture and taste.

How to Store Matilda's Chocolate Cake

For best results, store the cake in an airtight container or cover it with a cake dome at room temperature for up to 2-3 days.

Tip: If your kitchen runs warm, you can refrigerate the cake instead-just be sure to wrap the entire cake or individual slices in plastic wrap to keep it from drying out. Let chilled cake come to room temperature before serving so the frosting stays soft and the moist chocolate cake layers are at their best.

This Matilda's chocolate cake recipe could become your favorite. Save it, and don't be surprised if it becomes the go-to dessert for special occasions or random Tuesdays. One bite will show you why it's perfect.
