Ingredients for Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Alright, let’s talk ingredients! Nothing too crazy here, promise! But a few things are important for getting that perfect cookie. So, here’s what you’ll need:
- 3/4 cup (that’s 12 Tbsp or 170g) of unsalted butter, softened. Seriously, softened is key!
- 2/3 cup (or 133g) of packed light or dark brown sugar. I usually go with light, but dark gives it a richer flavor!
- 1 large egg, at room temperature. It mixes better, trust me!
- 1 teaspoon of pure vanilla extract. Don’t skimp on the good stuff!
- 2 cups (250g) of all-purpose flour. Make sure you spoon it into the measuring cup and level it off. We don’t want too much flour!
- 1/2 teaspoon of ground cinnamon. Adds a little warmth, ya know?
- 1/4 teaspoon of salt. Balances out the sweetness!
- 1 cup (120g) of toasted and finely chopped hazelnuts, divided. We’ll use some in the dough and some for topping!
- Optional: Coarse sugar for rolling. Gives ’em a little sparkle!
- 8 ounces (226g) of milk chocolate, coarsely chopped. I like using a good quality chocolate bar for this!
Ingredient notes for Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
A few extra notes on some of these, just so we’re all on the same page!
Butter
Unsalted butter is the way to go, so we can control the saltiness. And seriously, make sure it’s softened! Not melted, not cold. Softened!
Brown Sugar
Light or dark brown sugar works! Dark brown will give you a slightly more molasses-y, intense flavor. I like both, honestly!
Hazelnuts
Toasted and finely chopped hazelnuts are a MUST. Toasting brings out the flavor, and finely chopping makes them easier to incorporate into the dough. I’ll tell you how to toast them later, don’t worry!
Milk Chocolate
Coarsely chopped milk chocolate is perfect for those melty, chocolatey chunks. You *could* use chocolate chips, but I think chopped chocolate melts better and looks prettier!
How to Prepare Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Okay, so here’s the fun part! Making the cookies! Don’t worry, it’s easier than you think! Just follow these steps, and you’ll be golden. Promise!
Preparing the Cookie Dough for Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
First, you’ll want to grab a large bowl and beat that softened butter for about a minute until it’s nice and smooth. Then, add in your brown sugar and beat until it’s all fluffy! Next, beat in the egg and vanilla extract until everything’s combined. In a separate bowl, whisk together the flour, cinnamon, and salt. Now, slowly mix the dry stuff into the wet stuff until it’s just combined. Don’t overmix! Beat in 3/4 cup of those yummy chopped hazelnuts. Divide the dough into two logs, wrap ’em up tight (plastic wrap works great), and chill in the fridge for at least 4 hours. This is MANDATORY! Trust me, the cookies will spread like crazy if you skip this step!

Baking the Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Alright, ready to bake? Preheat your oven to 350°F (that’s 177°C). Line your baking sheets with parchment paper (makes life SO much easier!). Remove those logs from the fridge and, if you want, roll them in some coarse sugar for a little sparkle. Slice the logs into about 12 cookies each and place them on the baking sheets. Bake for 12-14 minutes, or until they’re nice and golden brown around the edges. Let them cool for about 5 minutes on the sheet, then transfer them to a cooling rack to cool completely.
Adding the Milk Chocolate and Hazelnut Topping to Your Toasted Hazelnut Slice and Bake Cookies
Now for my favorite part: the chocolate! Melt that chopped milk chocolate. You can use a double boiler or just pop it in the microwave in 30-second intervals, stirring in between, until it’s smooth. Careful not to burn it! Dip each cookie halfway into the melted chocolate (ooh, so pretty!). Sprinkle with the remaining chopped hazelnuts. Pop the cookies in the fridge to let the chocolate set. And then… ENJOY!
Tips for Perfect Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Want to take these cookies from “good” to “OMG AMAZING”? Here are a few little secrets I’ve learned along the way!
Chilling the Dough is Crucial
Seriously, DO NOT skip the chilling! It firms up the butter, which prevents the cookies from spreading too thin. Plus, it develops the flavor. So, patience, my friend!
Toasting Hazelnuts for Enhanced Flavor
Toasting the hazelnuts is a GAME CHANGER! Just spread them on a baking sheet and bake at 350°F (177°C) for about 10-12 minutes, until they’re fragrant and the skins start to crack. Let them cool slightly, then rub them in a clean kitchen towel to remove the skins. So worth it!
Melting Chocolate Perfectly
Melting chocolate can be tricky, but don’t worry! Use a double boiler or microwave in short intervals, stirring in between. If it seizes (gets clumpy), try adding a teaspoon of vegetable oil or shortening. It can save it! Careful, it splatters!
Storage and Reheating Instructions for Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Okay, so you’ve made these amazing cookies… now what? Here’s how to keep ’em fresh (and how to make ’em even better!).
Storing Your Baked Cookies
To keep these cookies fresh, store them in an airtight container at room temperature. They should last for about 3-4 days… if they even last that long! I doubt it!
Reheating for a Warm Treat
Want a warm, gooey cookie? Pop one in the microwave for about 5-10 seconds. Or, you can warm them in a low oven (like 300°F/150°C) for a few minutes. Yum!
Variations on Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Okay, so you’ve mastered the basic recipe? Awesome! Now, let’s get a little crazy and try some fun variations! These cookies are super adaptable, so don’t be afraid to experiment!
Different Chocolate Options
Not a milk chocolate fan? No problem! Try dark chocolate for a richer, more intense flavor. Or, go for white chocolate for a super sweet treat. You could even swirl different chocolates together! Ooh, fancy!
Adding Spices
Want to add a little extra warmth? Try adding a pinch of nutmeg or cardamom to the dough. It’ll give ’em a cozy, holiday vibe! I’m thinking of trying ginger next time!
Nut Variations
Hazelnuts not your thing? Swap ’em out for almonds, walnuts, or pecans! Just make sure you toast ’em first, for that extra nutty flavor. You could even use a mix of different nuts! So good!
FAQ About Toasted Hazelnut Slice and Bake Cookies with Milk Chocolate
Got questions? I’ve got answers! Here are a few common questions I get about these amazing cookies. Don’t worry, I’ve got you covered!
Can I use pre-chopped hazelnuts?
Okay, so you *can* use pre-chopped hazelnuts, but honestly, I don’t recommend it. They’re often not as fresh, and they might not toast as evenly. Plus, chopping your own gives you more control over the size. But hey, if you’re short on time, go for it! Just try to find good quality ones!
How long will the cookie dough last in the refrigerator?
The cookie dough will last in the refrigerator for about 3-4 days. Just make sure it’s wrapped tightly! After that, it might start to dry out a bit. But honestly, it never lasts that long in my house! We always bake it up before then!
Can I freeze the cookie dough?
YES! You can totally freeze the cookie dough! Just wrap the logs tightly in plastic wrap and then in a freezer bag. It’ll last for up to 2 months. When you’re ready to bake, just thaw it in the refrigerator overnight and slice and bake as usual. So convenient!
What if my chocolate seizes when melting?
Ugh, seized chocolate is the WORST! But don’t panic! Try stirring in a teaspoon of vegetable oil or shortening. Sometimes that can bring it back. Also, make sure you’re not overheating it! Low and slow is the way to go!
