These Hazelnut Toffee Chocolate Chip Cookies are so good that friends and family will come running any time you make these. Chunks of homemade hazelnut toffee are mixed into chocolate chip cookie dough and when you bake them the toffee melts creating these delicious puddles of caramel that are so good with the bittersweet chocolate and crunch of the hazelnuts.
Hazelnut Toffee Chocolate Chip Cookie Ingredients
Homemade hazelnut toffee is what makes this cookie extra special. While the cookies bake, the toffee melts and becomes soft and even more delicious. The hazelnut toffee is very easy to make and worth the extra effort. The ingredients for the toffee are:
- Granulated Sugar
- Unsalted Butter
- Kosher Salt
- Toasted Hazelnuts
The chocolate chip cookie recipe is one I've been using for years and I absolutely love it. Chocolate chip cookies was one of the first recipes I posted on this blog and when I want something a little sweet this recipe is it. The ingredients for the cookies are:
- Unsalted Butter. Use good quality butter. The quality will make a difference in the taste of the cookie and how much it spreads.
- Dark Brown Sugar. Brown sugar interacts with the baking soda to make the cookies chewy, and soft. The brown sugar also produces a moist cookie with a nice molasses/toffee flavor.
- Granulated Sugar. Granulated sugar helps produce crispy edges.
- Vanilla Extract. Pure vanilla is a great flavor booster for this cookie
- Whole Eggs. Eggs are the binder for the cookie dough. The egg yolks contribute moister to the cookie, while the egg whites provide structure.
- Baking Soda. Baking soda is the leavening and helps produce a cookie that is tender.
- Kosher Salt. Salt helps amplify all the other flavors in the cookie
- All-Purpose Flour. I use unbleached all-purpose flour for this recipe. I haven't made a gluten-free version yet, but I've had success with Bob's Red Mill Glutenn-Free flour in other recipes.
- Bittersweet or Semi-Sweet Chocolate. I use either bittersweet or semi-sweet whenever I made chocolate chip cookies. My preferred brand is Ghirardelli's bittersweet chips or I chop up a large chocolate bar.
Nuts are optional for a good chocolate chip recipe, but when I do add them I always go for pecans.
How to Make the Hazelnut Toffee
The recipe for toffee is a basic candy making recipe. The base recipe has equal amounts of sugar and butter, 1 cup each. A little water is used to help the sugar melt at the beginning without melting it and salt and vanilla for flavoring. The key to success is making sure the toffee mixture gets is between 290 and 300°F when you remove it from the stove and add the nuts.
Tips for Success
Measure out all your ingredients before starting. Once the toffee reaches the right temperature you don't have time to measure the vanilla or nuts.
To ensure that your toffee gets to the right temperature you need to have an accurate candy thermometer or instant-read thermometer. I regularly test my candy thermometer by measuring boiling water. It should read 100°C or 212°F.
Place the sugar, water, butter and salt in the 3-quart saucepan. Attach the candy thermometer to the side of the pan. Bring the mixture to a boil over medium-high heat. Stir the toffee constantly to prevent it from sticking or burning.
Once the toffee reaches the right temperate remove it from the heat, quickly dump in the hazelnuts and stir fast to incorporate the nuts. Scrape the nut-filled mixture onto a Silpat lined baking sheet before the toffee hardens and use the spatula to spread it so all the nuts are in a single layer.
It will take about 90 minutes for the toffee to harden and cool. Once it is cooled, break it into large pieces and then use a knife to cut it into 1/2-inch to 1-inch chunks. Set aside while you make the chocolate chip cookie dough.
How to Make the Chocolate Chip Cookies
Start with room temperature butter and eggs. This step may sound strange when the dough will be refrigerated for 24 hours, but room temperature ensures that all the ingredients incorporate well.
Start by combining all the flour, salt and baking soda and whisking them together for 30 seconds to make sure the baking soda and salt and evenly dispersed throughout the flour.
Place the sugars, butter and vanilla in the bowl of stand mixture and beat on medium speed until the mixture is lighter in cooler and looks fluffy. Add the eggs one at a time, mixing after each addition.
Dump all the dry ingredients in at one time and mix on low speed until the flour mixture is incorporated. Add the chocolate chips (or chopped chocolate), mix on low speed until it is even dispersed throughout the dough. Add the chopped hazelnut toffee, mix in and then refrigerate the cookie dough for 24-48 hours.
Why the Cookie Dough is Refrigerated
Refrigerating the cookie dough is something I learned from Stella Parks at Serious Eats food site. Refrigerating it for at least 24 hours results in a cookie dough that is drier and firmer. When the cookies are baked they will hold their shape better. The flavors also have a chance to meld and the cookies have a deeper toffee-like flavor.
Baking the Cookies
Preheat the oven to 375°F. Remove the cookie dough from the refrigerator 5 to 10 minutes to allow it to soften and make it easier to scoop.
Cookie Size. If you are making large cookies this recipe makes 24 cookies. If you are making small cookies this recipes makes about 48 cookies. Because of the chunks of toffee and the size of the hazelnuts I recommend making the large cookies.
Tip for Success
Use a cookie scoop to shape the cookies dough. Using a scoop will ensure that the cookies are the same size. Use a large scoop that holds 3 tablespoons.
The cookies will bake for about 12 minutes. The time depends on how dark your like your cookies. If you've made chocolate chip cookies before you know how light or dark you like your cookies
- Bake the cookies for 8 minutes, check them. If they're not mostly flat bake them for another 2 minutes.
- The melting toffee can create odd shapes for the cookies. If the cookies are flat after 10 minutes, remove the cookies from the oven and use an offset palette knife to reshape the cookies into rough shapes. Work quickly.
- Return the cookies to the oven and bake for another 1-2 minutes.
- Remove them from the oven, cool for 1-2 minutes and then place on a cooling rack.
