Gooey, Fudgy, Chocolate Bliss
This hot fudge chocolate cake is not your average chocolate cake recipe – it’s rich, melty, and downright irresistible. Think of it as a cross between a fudgy chocolate cake and a lava cake, but better. Because not only is it decadent and deeply chocolatey, it’s also a sneaky protein cake with 10g of protein per serving. That means you can totally justify going in for seconds.

Why You’ll Love this Hot Fudge Chocolate Cake
If you’ve ever had one of those warm desserts where you cut in and a pool of chocolate sauce floods your plate…yeah, this is that. Except instead of stuffing it with fudge, the hot fudge layer forms all on its own as it bakes. Magic? Almost. The trick? A layer of hot water poured right on top before it hits the oven. What comes out is a beautifully soft cake on top, and a luscious, warm fudge sauce underneath. Scoop it up while it’s hot and serve with a scoop of vanilla protein ice cream for the ultimate experience.
You don’t need any fancy ingredients or baking skills to make this work. Just stir together a thick batter, fold in chocolate chunks (non-negotiable), and get ready for your kitchen to smell like a dream. It’s a single-pan dessert that checks every box – easy, high-protein, and ridiculously good.
Whether you’re craving comfort or need something quick and indulgent to wrap up the night, this fudgy chocolate cake delivers. No one would ever guess it’s a better-for-you version… and honestly, they don’t need to.
