These ultra-fudgy brownies are rich, gooey, and packed with dark and white chocolate chunks. Baked in a standard 9×13-inch pan and finished with a golden butterscotch drizzle, they’re the perfect cozy treat.

If you’re looking for the kind of brownies that make people stop mid-bite and say “whoa”, you’ve just landed on your signature bake. These thick, fudgy brownies come together in one bowl and are baked in a standard 9×13-inch pan for that perfect slab-style indulgence. They’re loaded with melty dark chocolate, sweet white chocolate chunks, and a handful of toasted walnuts (optional but delightful). The crackly top is that glossy, paper-thin magic layer we all chase. But the twist? A warm butterscotch drizzle that takes them over the top.

Tips for Perfect Brownies

Whip your eggs and sugar well: 1–2 minutes of vigorous whisking after adding eggs gives the big volume.

Do not overbake: Fudgy brownies need to come out when a toothpick has moist crumbs—not totally clean.

Chill to slice: For clean, bakery-style cuts, chill the full pan before slicing.

FAQ

Can I add nuts?
Yes, you don’t have to change anything in the batter.

How do I store the brownies?
Once fully cooled, store in an airtight container at room temp for 3–4 days or in the fridge for up to a week. They also freeze beautifully (wrap individually and freeze for up to 2 months).

Do I need a mixer?
Nope! You can make the whole batter with just a whisk and spatula.

Ingredients

Yield: 12-16 brownies
Pan: 9×13-inch or 26×22 cm
Bake Time: 25–30 minutes
Total Time:
~1 hr + cooling

For the Brownies
  • 225g (1 cup) unsalted butter
  • 200g (7 oz) 70% dark chocolate, chopped or chips
  • 250g (1 ¼ cups) granulated sugar
  • 100g (½ cup, packed) light brown sugar
  • 4 large eggs, room temperature
  • 1 ½ tsp vanilla extract
  • 70g (¾ cup) unsweetened cocoa powder
  • 120g (1 cup) all-purpose flour
  • ½ tsp salt
  • 100g (3.5 oz) white chocolate, chopped
  • Optional: 100g (3.5 oz) toasted walnuts, chopped
For the Butterscotch Drizzle
  • 60g (¼ cup) unsalted butter
  • 100g (½ cup, packed) brown sugar
  • 120ml (½ cup) heavy cream
  • ½ tsp vanilla extract
  • Pinch of salt

Directions

  1. Prep & Preheat
    • Preheat oven to 170°C (340°F). Grease and line a 26×22 cm (or 9×13-inch) pan with parchment paper, leaving overhang.
  2. Melt chocolate + butter
    • In a large bowl, melt butter and dark chocolate together over a double boiler or in short microwave bursts. Stir smooth and let cool for 10 mins.
  3. Whisk eggs + sugar
    • Add both sugars and eggs into a bowl and whisk well. Add vanilla. Whisk for 1–2 minutes until glossy—this step gives the crackly top.
  4. Add the cooled chocolate-butter mixture to the whipped eggs and sugar and mix gently.
  5. Add dry ingredients
    • Sift in cocoa powder, flour, and salt. Fold until mostly combined.
  6. Mix-ins
    • Fold in white chocolate chunks (and any optional mix-ins).
  7. Bake
    • Spread batter into pan. Bake for 25–30 minutes until the top is shiny and crackled, edges are set, and a toothpick comes out with moist crumbs (not raw batter).
  8. Cool & Chill (Important!)
    • Cool in the pan for 20–30 minutes.
    • Move to the fridge (covered or uncovered) and chill for 1 hour before slicing. This helps set the texture and gives cleaner cuts.
  9. Make the butterscotch sauce
    • In a small pan, melt butter and brown sugar.
    • Stir until sugar dissolves.
    • Add cream slowly, stir continuously.
    • Let simmer 3–4 mins until slightly thickened.
    • Remove from heat, add vanilla and salt.
    • Let cool slightly before drizzling.
  10. Slice & Serve
    • Cut brownies into squares and serve with a drizzle of warm butterscotch sauce. Optional: sea salt flakes on top.

What’s New

Notes

Want a deeper chocolate flavor? Add 1 tsp espresso powder to the dry mix.

For thicker brownies, don’t spread to edges—leave a border to pile the batter higher.

These are even better the next day once the flavors settle.
