Delia Smith Brownie Recipe

The difference between a good brownie and a great one usually comes down to about two minutes in the oven.

I’ve made more batches of brownies than I can count, chasing that perfect balance — crisp, crackly top, dense fudgy middle, and absolutely no trace of cakey dryness.

This recipe is the one that finally nailed it for me, and the whole secret is knowing exactly when to pull the tin out of the oven, even when your instincts are telling you it needs longer.

Why Slightly Underbaking Is the Secret to Fudgy Brownies

The biggest mistake people make with brownies is treating them like cake — baking until a skewer comes out completely clean.

Brownies actually want a slightly different test. You’re looking for a skewer that comes out with a few moist crumbs still clinging to it, not one that’s spotless.

Take them out at that exact point, and the residual heat in the tin finishes the cooking as they cool, settling into that dense, fudgy texture brownies are famous for.

Leave them in until the skewer is completely clean, and you’ll end up with something closer to chocolate cake — still nice, but missing that proper gooey middle.

Ingredients for Delia Smith Brownies

• 200g dark chocolate (around 70% cocoa), broken into pieces
• 175g unsalted butter, cubed
• 3 large eggs
• 275g caster sugar
• 1 tsp vanilla extract
• 100g plain flour
• 30g cocoa powder
• ¼ tsp salt
• 100g chocolate chips or chopped chocolate (optional, for extra pockets of gooeyness)

How to Make Delia Smith Brownies — Step by Step

Step 1 — Preheat and Prepare

Preheat your oven to 180°C (160°C fan / Gas 4). Grease and line a 23cm square baking tin with parchment paper, leaving a little overhang on two sides to lift the brownies out later.

Step 2 — Melt the Chocolate and Butter

Melt the dark chocolate and butter together, either in short bursts in the microwave or in a heatproof bowl set over a pan of gently simmering water, stirring until completely smooth. Set aside to cool slightly.

Step 3 — Whisk the Eggs and Sugar

In a separate large bowl, whisk the eggs, caster sugar and vanilla extract together for 3–4 minutes, until pale, thick, and roughly doubled in volume. This step is what gives brownies their characteristic crackly top, so don’t rush it.

Step 4 — Fold in the Chocolate Mixture

Pour the slightly cooled melted chocolate and butter into the egg mixture and fold in gently until fully combined.

Step 5 — Add the Dry Ingredients

Sift in the flour, cocoa powder and salt, then fold gently with a large spatula until just combined — stop as soon as you can no longer see streaks of flour. Overmixing at this stage will make the brownies tougher.

Step 6 — Add Extra Chocolate

Fold in the chocolate chips or chopped chocolate, if using, for extra pockets of melted chocolate through the finished bake.

Step 7 — Bake

Pour the batter into the prepared tin and spread evenly. Bake for 25–28 minutes.

Step 8 — Test Carefully

Test with a skewer inserted into the centre — you want it to come out with a few moist crumbs clinging to it, not completely clean. If it’s still wet with raw batter, give it a few more minutes.

Step 9 — Cool in the Tin

Leave the brownies to cool completely in the tin before lifting out and slicing — this is essential for getting clean, fudgy squares rather than a crumbly mess.

My Top Tips for the Best Delia Smith Brownies

Don’t overbake them. Pull the tin out when the skewer still has a few moist crumbs on it, not when it’s completely clean — the brownies will finish setting as they cool in the tin.

Whisk the eggs and sugar properly. Those 3–4 minutes of whisking are what give you that shiny, crackly top that separates a good brownie from a great one.

Let them cool completely before cutting. I know it’s tempting to cut in while they’re warm, but the texture only fully sets once they’ve cooled, and you’ll get much neater squares.

Use a good quality dark chocolate. Since chocolate is the main flavour here, it’s worth using one you’d actually enjoy eating on its own — around 70% cocoa gives the best balance of rich flavour without being bitter.

Cut with a hot, clean knife for neat squares. Run the knife under hot water and wipe it dry between each cut for that clean, bakery-style edge.

Serving Suggestions

Brownies are wonderful just as they are with a cup of tea, but they’re equally good warmed slightly and served with a scoop of vanilla ice cream and a drizzle of chocolate sauce for a proper pudding. I also love them crumbled over ice cream, or sandwiched with a little whipped cream for something more indulgent.

How to Store Delia Smith Brownies

In the fridge: Not necessary, though they’ll keep well in an airtight container in the fridge for up to a week if you prefer them slightly firmer and fudgier.

At room temperature: Store in an airtight container for up to 5 days — they’ll stay just as fudgy at room temperature.

In the freezer: Freeze cut squares, wrapped individually or layered with greaseproof paper, for up to 3 months. Defrost at room temperature, or warm briefly in the microwave for a just-baked feel.

Notes

Test with a skewer for moist crumbs, not a completely clean skewer — this is the key to a proper fudgy texture.

Whisking the eggs and sugar thoroughly is what gives you that classic crackly top.

Cool completely in the tin before cutting for clean, neat squares.

Cut with a hot, clean knife between slices for the neatest edges.

Freeze cut squares for up to 3 months.

Frequently Asked Questions About Delia Smith Brownies

Why are my brownies cakey instead of fudgy?

This almost always means they’ve been overbaked, or too much flour was used. Test with a skewer and take them out while a few moist crumbs still cling to it, and measure your flour accurately rather than guessing.

Why did my brownies sink in the middle?

A slight dip in the centre is completely normal for a proper fudgy brownie and isn’t a fault. If it’s sinking dramatically, the batter may not have baked for quite long enough — check with a skewer before assuming it’s ready.

Can I make these ahead of time?

Yes, brownies are actually better made a day ahead — the flavour and texture settle further overnight, and they’re much easier to cut into neat squares once fully cooled.

Why is my crackly top not forming?

The crackly top comes from properly whisking the eggs and sugar until pale and thickened before adding the chocolate. If this step is rushed, you’ll still get a delicious brownie, just without that shiny, papery crust on top.
