The History

While the exact origin of this cake is a bit mysterious, its rise to Pinterest fame began in the early 2020s when home bakers started sharing their versions online. Inspired by classic chocolate layer cakes and rich fudge brownies, this cake combines the best of both worlds. Its popularity soared due to its simplicity, show-stopping appearance, and mouthwatering taste — perfect for both novice and experienced bakers.

Ingredients Breakdown

This cake is made from scratch using high-quality ingredients to ensure the best flavor and texture. The cake layers are fluffy and moist, while the fudge layers are thick, rich, and ultra-chocolaty. Here’s what makes it so special:

Butter and Oil: Provides moisture and a tender crumb.
Cocoa Powder: Adds deep chocolate flavor without overpowering sweetness.
Semi-Sweet Chocolate: Melts into a silky, rich fudge layer.
Buttermilk: Keeps the cake soft and adds a slight tanginess.
Baking Soda & Vinegar: Creates a light and airy texture.

Step-by-Step Recipe

Prep: Preheat oven to 350°F (175°C). Grease and flour three 8-inch round cake pans.
Mix Dry Ingredients: In a large bowl, sift together flour, cocoa powder, baking soda, and salt.
Add Wet Ingredients: Stir in sugar, oil, eggs, buttermilk, and vanilla until smooth.
Activate Leavening: Mix in vinegar until just combined — the batter will bubble slightly.
Bake: Divide batter into pans and bake for 25–30 minutes. Cool completely.
Make Fudge Layers: Melt chocolate and butter together, then spread between each cake layer.
Frost and Decorate: Frost the entire cake with chocolate buttercream and top with chocolate shavings or sprinkles.

Tips

Cool Completely: Let the cake layers cool for at least 1 hour before assembling to prevent melting the fudge.
Use Room Temperature Ingredients: For smooth mixing and even baking, ensure eggs and buttermilk are at room temperature.
Don’t Overmix: Once you add the dry ingredients to the wet, mix just until combined to avoid a tough texture.
Chill the Cake: Refrigerate the assembled cake for 30 minutes before serving for cleaner slices.

Variations and Customizations

Flavor Boosts: Add espresso powder to the cake batter for a mocha twist.
Gluten-Free: Substitute the flour with a 1:1 gluten-free all-purpose flour blend.
Dairy-Free: Use vegan butter and coconut milk in place of dairy ingredients.
Layer Variations: Add a layer of ganache, caramel, or peanut butter between the fudge layers.
Decoration Ideas: Top with fresh berries, edible gold dust, or crushed candy canes for festive flair.
