- 1/4 cup Light Corn Syrup (helps create a chewy texture)
- 1/2 cup Brown Sugar (packed)
- 1 Large Egg (room temperature)
- 1 tsp Vanilla Extract (pure vanilla)
- 1 1/2 cups All-Purpose Flour (sifted)

Instructions
Preheat Oven
Set the oven to 350°F (175°C) and let it preheat while you prepare the batter.
Time: PT5M
Temperature: 350°F
Prepare Baking Sheet
Line a standard baking sheet with parchment paper, allowing a slight overhang for easy removal.
Time: PT2M
Melt Butter and Combine Sugars
In a mixing bowl, melt the butter over low heat or in the microwave (30 seconds). Stir in granulated sugar, brown sugar, and corn syrup until smooth.
Time: PT5M
Add Egg and Vanilla
Whisk in the egg and vanilla extract until fully incorporated.
Time: PT2M
Combine Dry Ingredients
In a separate small bowl, whisk together sifted flour, baking soda, and salt.
Time: PT2M
Mix Wet and Dry
Gradually fold the dry mixture into the wet mixture using a spatula until just combined; do not over‑mix.
Time: PT3M
Add Chocolate Chips and Walnuts
Stir in the semi‑sweet chocolate chips, milk chocolate chips, and toasted walnuts until evenly distributed.
Time: PT3M
Transfer to Pan
Spread the batter evenly onto the prepared baking sheet, pressing gently with the spatula to create a smooth, compact layer. This step creates the signature crispy bottom.
Time: PT3M
Bake
Place the sheet in the middle rack and bake for 12‑15 minutes, or until the edges are set and the top looks slightly glossy but not browned.
Time: PT15M
Temperature: 350°F
Cool
Remove from the oven, let the sheet rest on a cooling rack for 20 minutes. The bars will firm up as they cool, giving a chewy center.
Time: PT20M

Using a sharp knife, cut the cooled slab into 8 equal bars. Sprinkle a pinch of sea‑salt flakes on each bar if desired.
Time: PT5M

Critical Steps — Do Not Skip
- Ensuring the butter‑sugar mixture is glossy but not browned (Step 3).

- Baking just until edges set to keep the center chewy (Step 9).
- Allowing the bars to cool completely before slicing (Step 10).
Chef Tips from the Video
- Use a mix of semi‑sweet and milk chocolate chips for layered meltiness.
- Toast walnuts with a pinch of sea salt for extra flavor depth.
- Line the pan with parchment and let the overhang hang over the sides; this makes lifting the whole slab out effortless.
Troubleshooting
Bars are too soft and fall apart when sliced.
Bake an additional 2‑3 minutes until the edges are firm. Allow full cooling time before cutting.
Bars are overly hard or crunchy throughout.
Reduce baking time by 2 minutes and check for a glossy top. Ensure the oven temperature is accurate.
Walnuts taste raw.
Toast walnuts in a dry skillet for 3‑4 minutes until fragrant before adding to the batter.
Storage
Refrigerator: Store in an airtight container for up to 5 days.
Freezer: Wrap tightly in plastic wrap and freeze for up to 2 months.
Room temperature: At room temperature for up to 1 day; after that, refrigerate.
Make-Ahead Tips
- Bake the bars up to 24 hours ahead and keep them sealed; they taste even better as flavors meld.
- If freezing, slice before freezing for easy portioning.
