I still have a big space in my heart (and tastebuds) for my Soft Chocolate Chip Cookies. They’re one of the most popular recipes on my website! Today’s recipe is similar, but I increased the chewy factor. Chocolate chunk cookies How to Make Chewy Chocolate Chip Cookies The cookie dough is made from standard ingredients: flour, leavener, salt, sugar, butter, egg, & vanilla. It’s the ratios of those ingredients that make this recipe stand out from the rest. Mix 2 and 1/4 cups of flour with 1 teaspoon of baking soda, 1/2 teaspoon of salt, and my favorite: cornstarch. I use 1 and 1/2 teaspoons of cornstarch in this recipe. Why cornstarch? Cornstarch gives the cookies that ultra soft consistency we all know and love. Plus, it helps keep the cookies beautifully thick. Use melted butter in this chocolate chip cookie recipe. Most of the cookies on my website call for creaming softened butter with the sugars. Chewy chocolate chip cookies require melted butter. Why melted butter? Melted butter produces the chewiest cookies. It can, however, make your baked cookie greasy, so I made sure there is enough flour to avoid that from happening. Since you are using melted butter, you don’t need a mixer for this cookie recipe. Stack of chocolate chip cookies Use More Brown Sugar Use a mix of brown sugar and white granulated sugar in your chocolate chip cookies. I prefer more brown sugar than white granulated sugar because the moisture in brown sugar promises an extra soft and chewy baked cookie. White granulated sugar is still necessary though. It’s dry and helps the cookies spread. A little bit of spread is a good thing. Too much cookie spreading? Here are my 10 Guaranteed Tips to Prevent Over-Spreading Extra Egg Yolk Another way to promise a super chewy chocolate chip cookie is to use an extra egg yolk. The extra egg yolk adds richness, soft tenderness, and binds the dough. You will need 1 egg and 1 egg yolk. You can freeze the extra egg white in a ziplock bag for up to 1 month or use it to make my Skinny Chocolate Peanut Butter Cupcakes. 🙂 chocolate chip cookie dough in bowl The dough will be soft and the chocolate chunks may not stick because of the melted butter. Just keep stirring it; I promise it will come together. The most important step is next. Chill the Chocolate Chip Cookie Dough Chilling the cookie dough is so important! Unless you want the cookies to spread into a massive cookie puddle, chilling the dough is mandatory for this cookie recipe. It allows the ingredients to settle together after the mixing stage but most importantly: cold dough results in thicker cookies. Cover the cookie dough and chill the dough for at least 2-3 hours and even up to 3-4 days. After chilling, let your cookie dough sit at room temperature for 10 minutes before rolling into balls. After chilling, sometimes I roll the cookie dough into balls and freeze them in a large zipped-top bag. Then I bake them straight from the freezer, keeping them in the oven for an extra minute. This way you can have just one of two cookies whenever you want! Chocolate chip cookies on silpat baking mat These cookies are huge–about 3 Tablespoons of dough is rolled to make one cookie. The batch only makes about 16 cookies since you will be rolling them so large. Feel free to make the cookies smaller (about 2 Tablespoons of dough per cookie) instead. If you do that, be sure to reduce the baking time by a couple minutes. When you remove the cookie dough from the refrigerator after chilling, the dough will be slightly crumbly. The warmth of your hands rolling it will make it stay intact. Roll the cookie dough balls taller, rather than wide as I discussed and showed in my cake batter chocolate chip cookies recipe. This little tried-and-true trick will result in thicker cookies. I do it for every single cookie I bake. Secrets to Thick, Soft, & Chewy Chocolate Chip Cookies Underbaked cookies are the secret to softness. Using cornstarch in the dough is another secret to softness, as well as the secret to thickness. Using more brown sugar than white sugar results in a moister, softer cookie. Adding an extra egg yolk increases chewiness. Rolling the cookie dough balls to be taller than wider increases thickness. Using melted butter (and slightly more flour) increases chewiness. Chilling the dough results in a thicker cookie.
