This “Dirty Thirty” brownie cake is built with three thick layers of rich, fudgy chocolate brownie and filled with smooth dulce de leche (also known as manjar blanco). Finished with a glossy caramel drip and elegant gold accents, it’s an indulgent birthday cake made for serious chocolate lovers. Handcrafted in our nut‑free Montreal kitchen, it’s perfect for 30th birthdays, milestone celebrations, or anyone who wants a decadent twist on a classic brownie cake.
