Gather These Ingredients

• 2 1/8 cups all-purpose flour – This forms the base of your cookie bars.

• 12 tablespoons unsalted butter – The star of the show, especially when browned.
• 1 cup packed brown sugar – Adds moisture and rich flavor.
• 1/2 cup granulated sugar – Balances the sweetness.
• 2 large eggs – Binds the mixture together.
• 2 teaspoons vanilla extract – Infuses a warm, aromatic flavor.
• 2 cups semi-sweet chocolate chips – The classic choice for chocolate lovers.
• 3/4 cup chopped hazelnuts (skins removed) – Provides a delightful crunch and nutty flavor.
• Sea salt for sprinkling – A finishing touch that enhances flavor.

What’s in the Gear List

Before you dive into the baking process, gather the necessary tools:

• Mixing Bowls – For combining the dry and wet ingredients.
• Whisk – To blend ingredients smoothly.
• Rubber Spatula – Perfect for folding in the chocolate chips and hazelnuts.

Brown Butter Chocolate Chip Hazelnut Cookie Bars: How It’s Done

Follow these steps to create your own batch of Brown Butter Chocolate Chip Hazelnut Cookie Bars:

Step 1: Brown the Butter

In a medium skillet over medium heat, melt the 12 tablespoons of unsalted butter. Stir frequently until the butter turns a golden brown and you can smell a nutty aroma. This usually takes about 5-7 minutes. Be careful not to burn it! Once browned, remove it from heat and let it cool slightly.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together the 2 1/8 cups of all-purpose flour, 1/2 teaspoon of sea salt, and 1/2 teaspoon of baking soda. Set aside.

Step 3: Combine Sugars and Eggs

In another mixing bowl, pour in the browned butter. Add the 1 cup of packed brown sugar and 1/2 cup of granulated sugar, and whisk until well combined. Then, add in the 2 large eggs and 2 teaspoons of vanilla extract, mixing until smooth and creamy.

Step 4: Combine Wet and Dry Mixtures

Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; it’s okay if there are a few flour streaks.

Step 5: Fold in Chocolate Chips and Hazelnuts

Using a rubber spatula, gently fold in the 2 cups of semi-sweet chocolate chips and 3/4 cup of chopped hazelnuts until evenly distributed throughout the dough.

Step 6: Prepare the Baking Pan

Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy removal. Spread the cookie dough evenly into the pan, smoothing the top with your spatula.

Step 7: Bake to Perfection

Bake in the preheated oven for 25-30 minutes, or until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs. Remove from the oven and let cool in the pan for a few minutes.

Step 8: Sprinkle with Sea Salt

Once the bars have cooled slightly, sprinkle a little sea salt on top for that extra flavor boost. Allow them to cool completely in the pan before lifting them out using the parchment overhang.

Step 9: Slice and Serve

Cut into squares or rectangles, and enjoy your Brown Butter Chocolate Chip Hazelnut Cookie Bars!

Spring–Summer–Fall–Winter Ideas

These cookie bars are versatile and can be enjoyed any time of year. Here are some ideas to enhance your baking experience:

• Spring: Add a handful of dried cherries for a fruity twist.
• Summer: Serve with a scoop of vanilla ice cream for a delightful dessert.
• Fall: Incorporate a touch of cinnamon for a warm, cozy flavor.
• Winter: Drizzle with melted white chocolate for a festive touch.

Don’t Do This

• Don’t skip browning the butter; it’s essential for the flavor!
• Don’t overmix the dough once the flour is added; it can result in tough bars.
• Don’t leave out the sea salt sprinkle; it makes a big difference in flavor.
• Don’t rush the cooling process; they are easier to cut when fully cooled.

• Store in an airtight container at room temperature for up to 5 days.
