Chunky Chocolate Chip Brownies
These brownies combine cocoa powder with both chopped cooking chocolate and jumbo chocolate chips for intensely chocolatey, fudgy results. Best enjoyed warm with ice cream or simply on their own.
Equipment
- Whisk
- Scales or measuring cups
- Large mixing bowl
- Silicone spatula
- 22 x 33 cm (9 x 13 inch) baking pan (or similar size)
- Parchment paper
Ingredients
- 250 grams butter (1 cup), melted
- 450 grams white sugar (2 cups)
- 4 large eggs, beaten
- 1 teaspoon vanilla extract
- 120 grams cocoa powder
- 120 grams plain flour (1 cup)
- 1 ½ teaspoons baking powder
- ½ teaspoon salt
- 150 grams cooking milk chocolate, broken into chunks
- 125 grams jumbo chocolate chips (for topping)
Instructions
-
Preheat the oven to 175°C fan (350°F). Line a 22 x 33 cm (9 x 13 in) pan with parchment paper, leaving an overhang to lift the brownies out later.
-
Melt the butter gently in short bursts in the microwave or over a low heat. You want it softened and melted, not hot.
-
Place the melted butter in a large bowl and stir in the sugar until combined.
-
Add the beaten eggs and vanilla extract, then whisk until the mixture is smooth and glossy.
-
Sift or add the plain flour, cocoa powder, baking powder and salt to the wet mixture. Stir gently to combine.
-
Fold in the broken cooking chocolate chunks so they’re evenly distributed. Fold only until the flour is no longer visible—do not overmix.
-
Pour the batter into the prepared pan and smooth the top with a spatula or the back of a spoon.
-
Scatter the jumbo chocolate chips evenly over the surface—these sit on top and keep their shape beautifully during baking.
-
Bake for 25–30 minutes. Ovens vary, so check from 20 minutes on. The brownies are ready when the top is shiny and small cracks appear—still soft in the middle is normal.
-
Remove from the oven and allow to cool in the pan for 1–2 hours. The center will firm up as it cools. Use the parchment overhang to lift the brownie slab from the pan and cut into squares or bars with a sharp knife.
-
Serve at room temperature or warm a square in the microwave for 20–30 seconds to revive that gooey center. They pair wonderfully with vanilla ice cream and chocolate sauce.

Homemade mix for Chunky Chocolate Chip Brownies
The key to deeply chocolatey brownies is the dry mix combined with high-quality chocolate pieces. Making the mix from scratch—rather than using a store packet—gives cleaner flavour and a better fudgy texture.
This recipe uses sugar, melted butter, vanilla extract, eggs, cocoa powder, plain flour, baking powder and salt. The combination yields a rich, gooey interior with a crackly top.
Melt the butter gently in short bursts if using a microwave, stirring between intervals. You want it melted but not hot.
Stir the melted butter with the sugar, then whisk in the beaten eggs and vanilla until smooth and combined. Add the dry ingredients and fold just until no pockets of flour remain. Finally, fold in cooking chocolate chunks so they melt slightly in the oven, creating pockets of molten chocolate.
Fold gently—overmixing develops gluten and can make the brownies cakier rather than fudgy.
What to bake brownies in?
Use a 22 x 33 cm (9 x 13 in) baking pan for a standard tray-bake thickness. Square pans work fine too. Thin aluminium pans conduct heat quickly and evenly for a classic tray-bake texture, while heavier pans may increase bake time slightly.
Should I line the pan when baking chocolate brownies?
Yes—line the pan with parchment or baking paper and leave an overhang to lift the brownies out easily after cooling. If you don’t have parchment, non-stick foil is an effective alternative. Greasing alone works in a pinch but makes removal more difficult.
When to add chocolate chips to brownies?
Scatter chocolate chips on top of the batter before baking. They keep their shape and provide appealing texture and pockets of melted chocolate on the surface.
How long to cook chocolate brownies for?
Baking time is normally 25–30 minutes, depending on your oven and pan. Look for a shiny top with small cracks. The centre should still be slightly soft; it will set as it cools.
My brownies aren’t cooked in the middle?
A soft centre straight from the oven is normal for fudgy brownies. If a toothpick comes out moist rather than dry, that’s expected. Allow the brownies to cool in the pan—this firms them up to the right texture.
When and how to cut brownies?
Wait 1–2 hours for the brownies to cool in the pan. Lift the slab out using the parchment overhang and cut into squares or rectangles with a sharp knife. For cleaner slices, chill briefly before cutting or wipe the knife between cuts.
How to store brownies?
Store cooled brownies in an airtight container at room temperature for up to 2 days. For longer storage, freeze cuts individually wrapped, then thaw at room temperature or warm briefly in the microwave.
What to serve with chocolate brownies?
Brownies are delicious on their own, but for a special treat serve warm with vanilla ice cream and chocolate sauce. Other options include whipped cream, custard, fruit coulis (such as raspberry sauce), fudge sauce or fresh berries.
How to heat Chunky Chocolate Chip Brownies
To serve warm, place a brownie square on a microwave-safe plate and heat for 20–30 seconds, depending on microwave power. Top with ice cream or a drizzle of chocolate sauce for a decadent dessert.
