Gluten-Free Flourless Double Chocolate Cake
Rich, dense flourless chocolate cake with deep cocoa and espresso notes, topped with silky chocolate ganache. The absence of flour creates an intensely fudgy crumb that's naturally gluten-free. Serve at room temperature for optimal flavor and texture. Perfect for chocolate lovers and elegant dinner parties. This version relies on melted chocolate and eggs for structure, delivering sophisticated results with minimal ingredients.

Tips
Stop and stir chocolate at 30-second intervals to prevent seizing. Patience ensures smooth, glossy results without grainy texture.
Cool cake 5 minutes before flipping to set structure slightly, reducing risk of breaking while removing from pan.
Ganache thickens as it cools. If it firms up too much before pouring, microwave 10-15 seconds to loosen.
Good to Know
Cover loosely and refrigerate up to 4 days. Ganache may crack slightly when cold; bring to room temperature 30 minutes before serving for best texture.
Cake can be baked 1 day ahead. Add ganache the morning of serving or up to 8 hours prior for cleaner appearance.
Serve at room temperature with whipped cream, fresh berries, or vanilla ice cream. Room-temperature cake highlights cocoa complexity.
Common Mistakes
Overheat chocolate to avoid seizing and grainy texture
Don't skip the 5-minute cooling before flipping to avoid structural collapse

FAQ
Can I substitute regular cocoa powder for Dutch process?
Yes, use equal amounts, but the flavor will be slightly more acidic and the crumb slightly drier. Dutch process is smoother and more chocolate-forward, but natural cocoa works in a pinch.
What if my ganache is too thick to pour?
Microwave in 10-15 second bursts, stirring between, until it reaches pourable consistency. Alternatively, whisk in cream 1 tablespoon at a time until the desired consistency is achieved.
How long can I keep this cake in the refrigerator?
Properly covered, the cake lasts 4 days refrigerated. It can be frozen up to 2 months without ganache; add glaze after thawing for best presentation.
