These double chocolate cookies are for serious chocolate lovers. The dough is made with cocoa for a deep, dark base, then loaded with chunks of real chocolate that melt into glossy pools as they bake. The result is a thick cookie with crisp edges, a chewy, fudgy middle and chocolate in every single bite.
The method uses melted butter, so there is no creaming and no mixer needed. A little extra egg yolk adds richness and chew, a pinch of cornflour keeps the centres soft, and a short chill in the fridge stops the cookies spreading too thin. Simple steps, bakery results.
Why These Cookies Stand Out
A lot of chocolate cookie recipes end up either dry and cakey or flat and greasy. This one is balanced to land right in the middle. Brown sugar keeps the texture chewy and adds a caramel note, while a little white sugar helps the edges crisp. Cocoa and chopped chocolate together give layers of flavour: the cocoa is earthy and intense, while the chunks are sweet and melty.
- Thick and chewy, not cakey.
- One bowl and a whisk.
- Dough can be made up to two days ahead or frozen.
- Perfect warm with milk or as a gift box treat.
Choosing Your Chocolate
The quality of the chocolate makes the biggest difference here. A bar of dark or semi-sweet chocolate chopped into rough chunks gives the best result, because the uneven pieces create both little flecks and big molten pockets. Chocolate chips work too, but they contain stabilisers that help them hold their shape, so you get neater dots rather than pools.
For the cocoa, unsweetened natural cocoa or Dutch-processed cocoa both work. Dutch-processed gives a darker colour and smoother, less sharp flavour. Avoid drinking chocolate or sweetened cocoa mixes, which make the dough too sweet and pale.
Double Chocolate Cookies Recipe: Chewy Centres, Crisp Edges
American · Dessert · Easy
Ingredients
- 115 g unsalted butter, melted and slightly cooled (1/2 cup)
- 150 g light brown sugar (3/4 cup, packed)
- 50 g caster sugar (1/4 cup)
- 1 large egg plus 1 egg yolk, at room temperature
- 2 tsp vanilla extract
- 160 g plain flour (1 1/4 cups)
- 40 g unsweetened cocoa powder (1/3 cup + 1 tbsp)
- 1 tsp cornflour
- 1/2 tsp bicarbonate of soda (baking soda)
- 1/2 tsp fine salt
- 170 g dark or semi-sweet chocolate, chopped into chunks, or chocolate chips (1 cup)
- Flaky sea salt, for sprinkling (optional)
Method
- Whisk the melted butter with both sugars for about 1 minute until smooth and glossy.
- Whisk in the egg, egg yolk and vanilla until well combined.
- Sift in the flour, cocoa, cornflour, bicarbonate of soda and salt, and fold until no dry streaks remain.
- Fold in three-quarters of the chocolate chunks.
- Cover the bowl and chill the dough for at least 30 minutes, or up to 48 hours.
- Heat the oven to 180°C (160°C fan) / 350°F and line two baking trays with baking paper.
- Scoop the dough into balls of about 40 g (2 tablespoons), place them 6 cm apart and press the remaining chocolate pieces on top.
- Bake one tray at a time for 10 to 12 minutes, until the edges are set but the centres still look soft and slightly underdone.
- Sprinkle with flaky salt if using, and leave on the tray for 5 to 10 minutes to firm up before moving to a rack.
Other Ingredients and Substitutions
- Butter: melted butter gives a dense, chewy texture. Let it cool slightly so it does not scramble the egg. Salted butter is fine; reduce the added salt to a pinch.
- Brown sugar: light or dark both work; dark brown gives extra chew and a toffee flavour.
- Egg yolk: adds fat and richness for a fudgier centre. If you prefer not to separate an egg, use one whole egg plus 1 tablespoon of milk; the cookies will be a little less chewy.
- Cornflour: keeps the centres tender. You can leave it out, but the cookies will be slightly firmer.
- Add-ins: swap some of the chocolate for white chocolate, chopped walnuts, hazelnuts or a handful of dried cherries.
How to Make Them, Step by Step
Mixing the Dough
Whisk the melted butter and sugars until they look glossy and slightly thickened. Add the egg and yolk and whisk again. Sifting the cocoa matters, because cocoa often has small lumps that stay as bitter dry pockets. Fold the dry ingredients in gently until just combined. The dough will be soft and quite sticky at first.
Chilling
Thirty minutes in the fridge firms the butter, so the cookies spread slowly and bake up thick. Longer chilling, up to 48 hours, also deepens the flavour as the flour hydrates. If the dough becomes too firm to scoop, leave it at room temperature for 10 minutes.
Shaping
Use an ice-cream scoop or two spoons for evenly sized balls, so they all bake at the same rate. Pressing a few extra chocolate chunks onto the tops before baking gives that attractive bakery look with visible melted chocolate.
Baking
Chocolate cookies are tricky to judge because you cannot rely on browning. Look at the edges: they should look set and matte, while the centres should still look puffy and a little underbaked. Take them out at this point. They continue cooking on the hot tray and firm up as they cool. Overbaking by just two minutes turns them dry and crunchy.
Tips for Bakery-Style Cookies
- Bake one tray at a time on the middle shelf for even heat.
- For perfectly round cookies, place a large round cutter or glass over each hot cookie and swirl it gently to tuck in the edges.
- Tap the tray firmly on the counter halfway through baking for crinkly, flatter tops.
- Let the trays cool between batches; dough placed on a hot tray spreads too fast.
- A little flaky sea salt on top makes the chocolate taste even richer.
Storing and Freezing
Keep cooled cookies in an airtight container at room temperature for up to 5 days. Adding a slice of bread to the container helps keep them soft. To refresh, warm a cookie in the microwave for 10 seconds and the chocolate turns melty again. Unbaked dough balls freeze very well: freeze them on a tray, then transfer to a bag for up to 3 months. Bake straight from frozen, adding 1 to 2 minutes to the baking time.
Frequently Asked Questions
Why did my double chocolate cookies spread too much?
The dough was too warm, the butter was hot when mixed, or the trays were warm. Chill the dough and use cool trays.
Why are my cookies cakey?
Too much flour or overbaking. Weigh the flour if you can, and remove the cookies while the centres still look soft.
Can I make them without eggs?
Replace the egg and yolk with 60 ml of milk and add 1/4 teaspoon of baking powder. The cookies are a little less chewy but still rich and delicious.
Can I make bigger cookies?
Yes. Scoop 80 g balls for large bakery-style cookies and bake for 13 to 15 minutes, still looking for set edges and soft centres.
Can I skip chilling the dough?
You can bake straight away, but the cookies will spread more and be thinner. Even 15 minutes in the freezer helps.
