Instructions
Brownie Layer
- Preheat oven to 350 degrees F / 170ºC and line a 9x9 inch (20x20cm) baking pan with parchment paper.
- In a large mixing bowl whisk the melted butter with sugar until the sugar is dissolved.
- Add in the eggs and whisk until combined.
- Pour in the melted chocolate and whisk until combined.
- Stir in the cacao powder, all-purpose flour, salt, and baking soda and mix until just combined.
- Set aside while making the cookie layer.
Cookie Layer
- In a bowl add butter and both sugars.
- Mix until the mixture is light and fluffy, around 5 minutes.
- Add in the egg and vanilla extract and mix until smooth and creamy.
- Fold in the flour and baking soda and again mix until combined.
- Finally, fold in the chocolate chips.
Assemble
- In the prepared baking pan pour the brownie batter and spread it into an even layer.
- Add a spoonful of cookie dough onto a brownie layer. Swirl with a spoon or knife.
- Bake for 15-20 minutes or until golden brown on top and a knife inserted comes out clean. Note on the baking time: Check these brownies after 15 minutes. If they are done, pull them out of the oven. Depending on your oven / calibration - they may need only 15 minutes and up to 35 minutes to cook through. Don't leave them in too long, or they will get dry!
- Allow to cool completely before removing from the pan (best overnight).
Notes
- My #1 Secret Tip for this Domino’s marbled cookie brownie recipe is to make sure the brownies have a fudgy texture by whisking together the butter and sugar thoroughly, but not overly mixing the brownie batter, or it will cause the brownies to be dense and heavy.
- Clean cuts: I always let the brownies cool all the way before slicing so they hold together and do not crumble.
- Cocoa choice: I use a good quality unsweetened cocoa powder because it makes the flavor so much richer.
- Swirl gently: I never mix the batters too much because I want each flavor to stand out on its own.
- Room temperature: I use room temperature ingredients for the cookie dough since it blends together so much smoother.
