If you want to make chocolate chip cookies but you’re not sure which type to make then why not try these chocolate chip swirl cookies. Half the cookie is double chocolate with white chocolate chips and the other half is a regular vanilla cookie with milk chocolate chips so you definitely get the best of both worlds.

These cookies are so easy and fun to bake and though they are simple, my 6-year-old daughter is always super impressed when I bake them. If you have any children in your family then this is a super fun recipe to bake with them.
This recipe is extra special because you get two types of cookies in one and who would say no to that. These cookies have the perfect combination of soft and chewy and they taste amazing. If you’re a cookie fan then you really need to give these cookies a try.

How to Make Chunky Chocolate Chip Swirl Cookies
Make the base for the cookies: Combine the butter and both sugars in a mixing bowl then mix in the vanilla extract and egg.
Split the base between two bowls: Pour half the mixture (around 165g) into a second mixing bowl. So now you have one bowl for the double chocolate chip cookies and one will be for the regular chocolate chip cookies.
Make the double chocolate cookies: To one of the mixing bowls, mix in the salt followed by the bicarbonate soda, cocoa powder, flour and white chocolate chips. Roll the double chocolate cookie dough into 6 even sized balls and set aside.
Make the regular chocolate chip cookies: To the second bowl, mix in the salt, bicarbonate soda, cornflour and flour then mix in the milk chocolate chips. Roll the chocolate cookie dough into 6 even sized balls.

Cut the dough balls in half: Use a knife and cut all 12 cookie dough balls in half then attach each double chocolate ball to a regular chocolate chip ball. Mould them tightly together so they stay togther.

Refrigerate the dough balls: Refrigerate the cookie dough balls for 1 hour. While the dough is in the fridge, preheat the oven to 180oC and line a baking tray with baking paper.
Bake the cookies: Arrange the cookies on the baking tray and slightly press them down so they are a disc shape. You can bake them in batches to ensure you leave space between them. Bake in the oven for 13 minutes. Allow the cookies to rest on the baking tray for 10 minutes then transfer the cookies to a cooling rack to completely cool.
Recipe Tips
- When you attach the different cookie dough balls together, ensure you mould them together tightly to avoid them detaching while baking.
Storage
Baked cookies can be stored at room temperature for up to 5 days though they are best enjoyed within 2 days. Unbaked cookies can be stored in the fridge for up to 2 days. Unbaked cookies can also be stored in the freezer for up to 3 months.

- Place as many cookies as you can onto the baking tray and slightly press on each cookie. Don't press them flat just slightly. Ensure there is space between each cookie. As this recipe makes 12 cookies, I bake 6 at a time but the choice is yours. Bake in the oven for 13 minutes then remove. If you want to add some additional chocolate chips to the outside then do this now while they are still warm. Allow the cookies to rest on the baking tray for 10 minutes then transfer the cookies to a cooling rack to completely cool.
