Molten-Style Fudgy Brownies

Molten-Style Fudgy Brownies

Time

  • Prep: 15 min
  • Cook: 35 min
  • Total: 1 hr (10 min inactive)

Servings: 12
Pan: 9x13-ish ceramic baking dish
Serving: 1 brownie (105 g / ~3.5 oz)

Ingredients

Brownie batter

  • Dark chocolate: 12 oz (340 g) — chopped; Ghirardelli 60% works well
  • Unsalted butter: 1 cup (227 g)
  • Granulated sugar: 1¾ cups (350 g)
  • Eggs: 4 large
  • Egg yolks: 1 large
  • Vanilla extract: 2 tsp
  • All-purpose flour: ¾ cup (90 g)
  • Kosher salt: ½ tsp — Diamond Crystal; use a little less if using finer salt

Optional molten pockets

  • Dark chocolate: 4 oz (115 g) — roughly chopped; optional but recommended

Instructions

1. Heat oven and prepare the dish

  • Heat oven to 325°F / 165°C.
  • Grease the baking dish well, or line it with parchment for easier removal.

2. Melt the chocolate and butter

  • Gently melt 12 oz (340 g) chopped dark chocolate and 1 cup (227 g) unsalted butter together:
    • Microwave: short bursts, stirring between each.
    • Stovetop: low heat or a bowl over barely simmering water.
  • Stir until smooth.

3. Whisk in sugar, eggs, and vanilla

  • Whisk in 1¾ cups (350 g) granulated sugar.
  • Add 4 large eggs one at a time, then whisk in 1 large egg yolk and 2 tsp vanilla extract.
  • Whisk until the batter looks glossy and smooth.

4. Add flour, salt, and optional chocolate

  • Stir in ¾ cup (90 g) all-purpose flour and ½ tsp kosher salt just until combined. Do not overmix.
  • Fold in 4 oz (115 g) chopped dark chocolate, if using.
  • Pour the batter into the prepared dish and spread evenly.
  • For even more molten pockets, reserve a handful of the chopped dark chocolate and press it lightly across the center of the batter before baking.

5. Bake

  • Bake 30-40 minutes, until:
    • The edges look set.
    • The center is still a little soft and slightly jiggly.
    • A toothpick comes out with wet, fudgy crumbs rather than clean.
  • Ceramic pans can run a little slower than metal, so start checking near the 30-minute mark and pull as soon as the center is softly set.

6. Rest briefly and serve warm

  • Rest 10-15 minutes only if you want the most lava-cake-like texture.
  • Cut and serve warm.
  • Good with vanilla ice cream.

Notes / Make-ahead / Variations

  • Sweeter, more classic brownie profile: increase the granulated sugar to 2 cups (400 g).
  • Darker, richer profile: keep the sugar at 1 3/4 cups (350 g).
  • The brownies will continue to set as they stand. If you bake until fully firm in the center, they will lose the molten texture.
