Breadfurst in NWDC does a fudgy chocolate torte made with almond flour.

Thanks all! I somehow never found these responses.

All sound great. If anyone has a recommendation for a great chocolate-hazelnut cake, that would be greatly appreciated too!

Checkout Praline or Tout de Sweet (both in Bethesda)

Kinda depends on whether/with what they’d want their dark chocolate complemented with other flavors.

Les Delices Bakery in Rockville, best cakes ever!

Stellas in Rockville does excellent fancy cakes, all delicious. http://www.stellasbakeryonline.com/

Also, it's not fancy - not sure what vibe you're going for - but the chocolate bundt at Nothing Bundt Cakes is amazing. I have never seen anyone not devour it - even people who don't like chocolate cake.

no one is answering you! THere is a great one at Wegmans

Any recommendations for a bakery in NW DC or close in MoCo that makes really good dark chocolate cake? This is for a milestone birthday celebration of someone who loves dark chocolate. Thank you!
