Description
This structural chocolate cake is specifically engineered for 3D sculpting and architectural carving. Paired with a firm bittersweet ganache and sleek marshmallow fondant, it provides the perfect balance of stability and rich flavor for creating edible automotive art.
Ingredients
- Unsalted butter, softened
- Granulated sugar
- Large eggs
- 500g all-purpose flour
- Baking powder
- Baking soda
- Salt
- Whole milk
- 510g bittersweet chocolate (couverture)
- Heavy cream (38% fat)
- Vanilla extract
- Marshmallow fondant
- Silver luster dust
- Clear alcohol (for painting)
Instructions
- Preheat oven to 350°F (177°C) and line a 15×17 inch sheet pan with parchment paper.
- Cream the butter and sugar in a stand mixer until light, then add eggs one at a time, allowing each to fully incorporate.
- Incorporate dry ingredients (flour, baking powder, baking soda, and salt) alternately with milk in three batches, mixing until just combined.
- Bake for 50–55 minutes on the middle rack until a skewer comes out clean, then cool completely on a wire rack.
- Prepare the ganache by melting bittersweet chocolate and heavy cream together in short microwave bursts; stir in vanilla and let set until it reaches a spreadable peanut butter consistency.
- Stack cake layers using ganache as an adhesive, then use a scale template and a serrated knife to carve the car’s silhouette and details.
- Apply a thin crumb coat of ganache over the carved cake, chill for 15 minutes, then apply a second thicker layer of ganache and smooth until perfectly defined.
- Roll out fondant to 3mm thickness, drape over the chilled cake, and smooth from the top down to eliminate air bubbles.
- Cut and attach fondant details like windows and bumpers using a small amount of water, then paint metallic accents with luster dust mixed with alcohol.
Notes
For the most precise carving results, wrap your cooled cake layers in plastic and chill them in the refrigerator for at least two hours or overnight; the cold fat makes the crumb significantly easier to shave without tearing. If you encounter any air bubbles under your fondant, use a tiny pin to prick the bubble and gently press the air out with a fondant smoother for a seamless finish.
