What Makes This Recipe Awesome

These brownies hit the sweet spot: fudgy in the middle, slightly chewy at the edges, and crowned with that coveted shiny, crinkly top. Everything happens in one bowl, so your sink doesn’t turn into a regret factory.

The recipe is flexible—use chips, chopped chocolate, or cocoa only—and still lands with major chocolate flavor. Bonus: it’s beginner-proof but impressive enough for dinner parties (or Netflix marathons, no judgment).

Shopping List – Ingredients

• 1/2 cup (115 g) unsalted butter
• 4 oz (115 g) semisweet or dark chocolate, chopped (or chips)
• 3/4 cup (150 g) granulated sugar
• 1/2 cup (100 g) packed light brown sugar
• 2 large eggs (room temperature if possible)
• 1 large egg yolk
• 1 1/2 tsp vanilla extract
• 1/2 cup (60 g) all-purpose flour
• 1/3 cup (35 g) Dutch-process cocoa powder (natural works too)
• 1/2 tsp fine sea salt
• 1/2 tsp espresso powder (optional, boosts chocolate)
• 1/2 cup (85 g) chocolate chips or chunks (optional mix-in)
• Flaky sea salt for topping (optional, highly recommended)

Instructions

1. Preheat your oven to 350°F (175°C). Line an 8-inch square pan with parchment, leaving overhang for easy lift-out.

   Lightly grease the parchment.

2. In a medium, microwave-safe bowl, melt butter and chopped chocolate in 20–30 second bursts, stirring between each, until smooth. Let it cool 2–3 minutes so it doesn’t scramble the eggs.
3. Whisk in the granulated sugar and brown sugar until glossy and thick. This helps build that shiny top we all brag about.
4. Add eggs, egg yolk, and vanilla.

   Whisk vigorously for 30–45 seconds until the batter looks satiny and slightly lighter. Consider this your arm workout.

5. Sift or sprinkle in the flour, cocoa powder, salt, and espresso powder. Switch to a spatula and fold gently until just combined.

   Do not overmix unless you enjoy cakey disappointment.

6. Fold in chocolate chips or chunks if using. The batter will be thick—perfect.
7. Spread into the prepared pan, smoothing the top. Sprinkle with a pinch of flaky sea salt if you’re bold.
8. Bake for 22–28 minutes, until the edges are set and the center has a slight jiggle.

   A toothpick should come out with moist crumbs, not wet batter.

9. Cool in the pan for at least 30–45 minutes. Lift out and slice with a warm knife for clean edges. Or don’t wait and accept the glorious mess; your call.

Keeping It Fresh

Store cooled brownies in an airtight container at room temp for 3–4 days.

They stay fudgy and fabulous. For longer storage, wrap snugly and freeze up to 2 months; thaw at room temp or microwave in 10-second bursts for gooey revival. Pro move: slice first, then freeze with parchment between pieces for grab-and-go treats.

Health Benefits

Yes, they’re brownies.

But there are wins here. Cocoa and dark chocolate bring antioxidants that can support mood and circulation—your taste buds already knew. Using a mix of brown and white sugar adds depth, allowing you to keep sweetness balanced without overloading. And portion control?

These are rich enough that a small square satisfies, IMO.

Want to push it further? Swap part of the butter for tahini or almond butter for healthy fats, or add walnuts for omega-3s and crunch. Not a kale salad, but not a total villain either (FYI: joy counts).

Common Mistakes to Avoid

• Overbaking: The top sets before the center—don’t wait for a dry toothpick.

  Aim for moist crumbs.

• Hot batter + eggs: If the chocolate-butter mix is too hot, you’ll get scrambled eggs. Let it cool a bit.
• Overmixing after flour: This builds gluten and makes brownies cakey. Fold just until combined.
• Wrong pan size: An 8-inch pan keeps them thick and fudgy.

  A 9-inch bakes quicker and thinner—adjust time.

• Skipping salt: Salt = flavor amplifier. Don’t fear it.
• Measuring flour heavy: Spoon and level. Too much flour kills fudginess.

Alternatives

• Gluten-Free: Use a 1:1 gluten-free baking blend or 1/3 cup almond flour + 3 tbsp tapioca starch.

  Expect extra fudginess.

• Dairy-Free: Swap butter for dairy-free butter or refined coconut oil. Use dairy-free chocolate.
• Egg-Free: Replace 2 eggs + 1 yolk with 1/3 cup unsweetened applesauce + 2 tbsp aquafaba. Texture shifts slightly but still rich.
• Extra Dark: Use 70–80% chocolate and add 1–2 tbsp more sugar to balance.
• Mix-Ins: Walnuts, pecans, peanut butter swirls, or crushed pretzels.

  Keep total add-ins to about 1/2–3/4 cup.

• Flavor Twists: Add 1/2 tsp peppermint extract, 1 tsp orange zest, or a splash of bourbon. Live a little.

FAQ

How do I get that shiny, crinkly top?

Whisk the eggs and sugars into the warm chocolate mixture until glossy, which helps create a meringue-like film. Don’t skimp on sugar—structure and shine depend on it.

Can I double the recipe?

Yes.

Use a 9×13-inch pan and bake about 25–32 minutes. Start checking at 24 minutes; every oven has a personality.

What if I only have cocoa powder, no chocolate?

Use 3/4 cup (75 g) cocoa total and increase butter to 3/4 cup (170 g). Expect deep chocolate flavor with a slightly less silky texture.

Why did my brownies turn cakey?

Likely overbaked or overmixed after adding flour.

Also, too much flour from heavy scooping will dry them out. Spoon-and-level and pull them while slightly under.

Can I cut back on sugar?

Yes, reduce by up to 1/4 cup total without wrecking structure. Any more and you’ll lose shine, moisture, and balance.

Consider darker chocolate instead for a less sweet vibe.

How do I know they’re done?

Edges set, center slightly puffed with a little wobble, and a toothpick comes out with damp crumbs. If it’s clean, you overshot.

What’s the best way to slice clean squares?

Cool completely, then use a warm, sharp knife, wiping between cuts. Or use a bench scraper to press straight down—surgeon-level edges.

Can I add frosting?

You can, but these are intensely fudgy and don’t need it.

If you insist, a thin chocolate ganache layer keeps the drama classy.

In Conclusion

These One-Bowl Chocolate Fudge Brownies are the dessert cheat code: minimal effort, maximal payoff, and a texture that keeps you coming back “just to even the row.” They’re flexible, forgiving, and outrageously chocolaty.
