Toasted Hazelnut Slice & Bake Cookies with Milk Chocolate - Sally's Baking Addiction (2024)

Toasted hazelnuts, vanilla, brown sugar, cinnamon, and milkchocolate totally converted me into a slice ‘n’ bake cookieenthusiast.

I’ve been going wild over slice ‘n’ bake cookies for 4 days straight. I made a batch on Monday. Wasn’t too happy with them. Totally flavorless, completely crumbly. Needed more butter and something interesting. On Tuesday,I made hazelnut “puddles”—not cookies. On Wednesday, the stars alignedbecause I landed on the perfect ratio of flour, butter, and flavor. I tested the recipe two more times yesterday (who wants to come over and help me eat all 689374 cookies?) and here we are now: toasted hazelnut slice ‘n’ bakes with oodles of melted milk chocolate. Recipe #9 in my annual Sally’s Cookie Palooza!

These slice ‘n’bake cookies are thick, crunchy on the edges, soft in the center, and full of brown sugar, vanilla, cinnamon, hazelnut, and buttery flavors. To top them off, I add a healthy dose of melted milk chocolate.This way I knew Kevin would eat them. And they’d look pretty in pictures. And it’s chocolate.Win win win.

I’ve made slice ‘n’ bake cookies dozens of timesover the pastseveral years, but I’ve never been particularly happy with their flavor. They always just sort of taste like… well… crumbles of butter. But everyone loves them! So I always make them during the holidays. But this year I wanted to share a recipe on my blog that I truly loved. And I knew slice ‘n’ bakes had the potential to be just as mouthwatering as a caramel chocolate mocha Oreo stuffed peanut buttersomething.

Aren’t they fun? I seriously love these.

Slice ‘n’ bake cookies could not be any easier. Thedough is sort of like my shortbread dough and basic roll-out dough for sugar cookies combined. Just completely basic ingredients like flour, sugar, egg and butter. In fact, that’s literally the base recipe. Those four ingredients. And, like I said above, the ratio of ingredients is what matters and could either leave you with dry, crumbly cookies, greasy puddle cookies, orslice ‘n’ bake perfection. Let’s focus on doing it right.

Creamed butter/sugar is the base of my slice ‘n’ bake cookies. I opt for using brown sugar instead of white sugar. If you know anything about me by now, you know that my favorite ingredient in the world is brown sugar and I use it whenever I can in dessert recipes. There’s flavor and moisture there! And it’s everything in today’s cookies. A dose of vanilla extract also adds wonderful flavor. To the creamed mixture goes 1 egg. Remember, room temperature egg. Always use room temperature egg when the recipe calls for room temperature or melted butter.Room temperature eggsemulsify so much easier into batter or dough, creating a uniform structure and texture throughout your baked good. Also, eggsincorporate morevolume into the batter when at room temperature. Temperature is imperative!

Now, the flour. You’ll need 2 cups, which is just enough to create a firm, yet still slightly soft cookie dough. Exactly the texture you want when making slice ‘n’ bake cookies. Then, a pinch of cinnamon and just enough finely chopped hazelnuts for flavor. And don’t forget to toast those hazelnutsbefore adding them. Here’s what I do: I toast chopped hazelnuts for 8 minutes in the oven. Let them cool down, then pulse them in a food processor a few times to really get a nice, fine chop. Or chop them up yourself. (A food processor is easiest though!)

Now, roll the dough up. You’ll want to do this on a floured surface with floured hands. Divide the dough in half, then roll each half into logs. The length of logs depends on how large you want your slice ‘n’ bake cookies. Because the longer the log, thesmaller in diameter the cookies. Make sense? My dough logs were about 8 inches long, making the cookies about 2.5 inches in diameter.

Roll the dough up very tightly in plastic wrap and refrigerate for at least 4 hours. I always chill the slice ‘n’ bake cookie dough in the refrigerator overnight, which makes this a convenient make-ahead recipe for cookie baking marathon days. Wait. You have those too, right?

The cookie dough has to be chilled for at least 4 hours or you will be left with greasy thin blob cookies. For lack of better words.

Now, it’s time toslice ‘n’ bake.

I roll the logs in coarse sugar for a little extra sparkle. That’s totally optional. You can also roll the logs in finely chopped hazelnuts, too.

And we’re DONE. Toasted hazelnut slice ‘n’ bake cookies with milk chocolate arecrazy simple to make with only a few base ingredients. The trickiest part, if we can even call it that, is rolling the cookie dough into logs. That’s why a floured surface is key to help you handle the cookie dough. The logs of cookie dough can chill out in the refrigerator for a few days, soit’s really easy to just take them out, slice ’em up, and pop into the oven. They’re soft in the centers, thick, crunchy on the edges, exploding with flavor, and super dense.
