Brownies + Cookies = Brookies!

Why choose 1 when you can have both desserts in one? Imagine fudgy brownie base with chunks of chocolate chip cookie dough baked right on top, some may say it’s better than Butterboy. The brownie layer is dense and chocolatey with that crackly top, while the cookie pieces stay soft and chewy throughout. Fair warning: these disappear fast, so you might want to make a double batch!

Understanding Your Components

1. Brownie Layer: This is a proper fudgy brownie made with brown butter, which adds an incredible nutty, caramelised depth that regular melted butter can’t match. The instant coffee intensifies the chocolate flavour without making it taste like coffee – it’s a baker’s secret weapon. The ratio of chocolate to flour creates that dense, fudgy texture rather than cakey. Semi-sweet chocolate gives you rich chocolate flavour without being overly sweet, which is important since the cookie layer adds sweetness too.
2. Cookie Dough Layer: This is a classic chocolate chip cookie dough – buttery, brown sugar-heavy for chewiness, loaded with chocolate chips. The dough gets dropped in chunks over the brownie batter rather than spreading it in a full layer. This creates pockets of cookie throughout rather than distinct layers, so you get both textures in almost every bite. Bicarbonate of soda (baking soda) gives the cookies that slightly crispy edge and chewy center.
3. Brown Butter: Browning the butter for the brownie layer transforms it from regular melted butter into something nutty, toasty, and complex. You cook it until the milk solids turn golden brown and smell like hazelnuts. This step takes 5-7 minutes but adds so much depth to the brownies. Don’t skip it – it’s what makes these brookies special.
4. Texture Balance: The key to great brookies is getting the bake time right – you want fudgy brownies that are just set, not overbaked and cakey, with cookie dough that’s baked through but still soft and chewy. Pulling them at 80% done (when a toothpick comes out mostly clean with a few moist crumbs) means they’ll finish cooking as they cool and stay perfectly fudgy.

Tips!

Watch the Brown Butter: Brown butter can go from perfect to burnt in seconds. Once the milk solids turn golden brown and smell nutty (not burnt), immediately pour it into another bowl to stop the cooking. Burnt butter tastes acrid and will ruin your brownies.

Melt Chocolate with Residual Heat: Pour the hot brown butter over the chopped chocolate and let it sit for a minute before stirring. The residual heat melts the chocolate gently without scorching it. Add the cocoa powder and coffee at this stage so everything melts together smoothly.

Beat the Eggs Well: Whisk the eggs and sugars until pale, fluffy, and increased in volume. This incorporates air and helps create that signature crackly top on brownies. It should look light and mousse-like before adding the chocolate.

Cookie Dough Chunks: Don’t spread cookie dough in an even layer – drop it in rough, irregular chunks over the brownie batter. Use a cookie scoop or spoon to create bite-sized pieces. These chunks sink slightly and create those pockets of cookie throughout.

Don’t Overbake: Pull them when a toothpick comes out mostly clean (80% done) with some moist crumbs clinging to it. The centre should still look slightly underdone – it will set as it cools. Overbaked brookies are dry and cakey instead of fudgy and chewy.

Cool Completely: Let brookies cool completely in the pan before cutting – at least 2 hours, ideally 4. Warm brookies are too soft to cut cleanly. To make the brookies extra fudgy, cover the cooled brookies with plastic wrap and refrigerate overnight. For the cleanest cuts, use a hot, dry knife.

Storage and Reheating Guide

• Fresh Storage: Store brookies in an airtight container at room temperature for up to 5 days – they stay fudgy and delicious
• Refrigeration: Refrigerate in an airtight container for up to 1 week. The texture becomes firmer and more fudge-like when cold.
• Freezing: Cut into squares and freeze in a single layer, then transfer to freezer bags for up to 3 months. Thaw at room temperature for 30 minutes before eating.
• Reheating: Microwave individual pieces for 10-15 seconds to get that warm, gooey texture back – amazing with ice cream!
• Texture Tip: Room temperature brookies are fudgier; cold brookies are denser and more fudge-like. Both are delicious!

Make Ahead Tips:

• Cookie Dough Ahead: Make cookie dough up to 3 days ahead and refrigerate, or freeze for up to 3 months. Scoop into chunks before refrigerating for easy assembly.
• Brown Butter Ahead: Brown butter can be made up to 1 week ahead and refrigerated. Melt gently before using.
• Bake Ahead: Bake brookies 1-2 days ahead and store at room temperature – they actually taste better the next day as flavors meld
• Freeze Unbaked: Assemble completely in the pan, cover tightly, and freeze for up to 2 months. Thaw completely before baking.
• Portion and Freeze: Cut into squares and freeze individually wrapped. Microwave from frozen for 20-30 seconds for a quick warm dessert anytime.

Method – How to make Brownies

1. Pre-heat your oven to 180C/350F.
2. Brownie mixture: In a small pot, brown the butter until golden and fragrant. Pour the brown butter into a small bowl and add in the chopped chocolate, instant coffee powder, cocoa powder and vanilla extract. Set aside to allow the chocolate to melt.
3. In a separate bowl, add in the eggs, brown sugar and white sugar, and whisk until the eggs are pale and fluffy. Pour the chocolate mixture into the egg mixture and mix to combine. Add the flour and salt into the mixture and whisk to combine.
4. Choc Chip Cookie Mixture: In a bowl, beat together the butter and sugars until it’s pale and fluffy. Add in the egg and vanilla extract, and whisk to combine. Add in the flour, bicarbonate soda and salt, and mix to combine. Lastly, add in the chocolate chips and stir to combine.
5. Spread your brownie batter evenly into a lined baking tin. Scatter bite-sized chunks of cookie dough over the top, and bake for 20–25 minutes until a toothpick inserted into the centre comes out mostly dry (about 80%).
