Molten Nutella Skillet Lava Brownie with Crackly Top

This skillet brownie is the ultimate dessert for chocolate lovers. A crackly, shiny top hides an ultra-fudgy interior, and the center holds a molten river of Nutella that flows out the moment you dig in.

Baked in a cast iron skillet, the edges turn chewy and crisp while the middle stays soft and gooey. Served warm with cold vanilla ice cream and toasted hazelnuts, every scoop is a contrast of textures and temperatures.

Molten chocolate desserts have a magic that never gets old, and this skillet version takes the idea to a new level. Instead of a single molten center, a frozen disk of Nutella is buried in rich brownie batter, so when the brownie bakes, the center stays liquid while the surrounding batter sets.

The result is a dessert that delivers a dramatic lava flow with every spoonful. The brownie itself is deeply chocolatey, with a thin, crackly crust that gives way to a dense, fudgy crumb. A scoop of vanilla ice cream adds cool creaminess, and toasted hazelnuts bring a welcome crunch. This recipe is straightforward, forgiving, and perfect for sharing straight from the pan.

Ingredients

Why this recipe works

The key to the crackly top is beating the eggs and sugar vigorously for a full 2 minutes. This aerates the mixture and creates a foam that sets into a shiny, crisp crust as it bakes. Skipping this step leads to a denser, less crackly top. The high sugar content also helps form that signature shell, so do not reduce the brown sugar.

Freezing the Nutella into a disk is what makes the lava effect work. As the brownie bakes, the frozen spread stays solid longer than the batter, so it melts slowly and creates a distinct molten pocket.

If the Nutella were at room temperature, it would blend into the batter and the center would be merely soft, not lava-like. The cast iron skillet also helps: it heats evenly and gives the edges a chewy, slightly crisp texture that contrasts with the soft center.

Notes and substitutions

Use a good-quality dark chocolate that you enjoy eating, since it is the main flavor. Semisweet or bittersweet both work. The brown sugar adds moisture and a hint of caramel, while the eggs provide structure. All-purpose flour and cocoa powder are the only dry ingredients, so the brownie stays fudgy rather than cakey.

A 10-inch cast iron skillet is ideal, but an 8-inch or 9-inch oven-safe skillet will also work; adjust the baking time slightly. If you do not have a skillet, an 8-inch square baking pan works, but the edges will not be as crisp.

The Nutella disk can be frozen in a small bowl or on a plate lined with parchment. For a nut-free version, skip the hazelnuts on top and use a chocolate spread without nuts.

• Nutella: Any chocolate-hazelnut spread can be used; freeze it in a disk as directed.
• dark chocolate: Semi-sweet or bittersweet chocolate works well; use a good melting variety.
• brown sugar: Light or dark brown sugar both work; dark adds more molasses flavor.
• hazelnuts: Skip the nuts or use toasted pecans or walnuts for crunch.
