Ingredients

Here's what you'll need to make these decadent Brown Butter Chocolate Chip Cookie Bars:

• 3/4 cup + 1 & 1/2 tbsp unsalted butter (192g)
• 1 tbsp milk powder (optional, enhances nuttiness)
• 1/2 cup white granulated sugar (100g)
• 2/3 cup soft light brown sugar (125g)
• 1 large egg + 1 egg yolk
• 2 cups all-purpose flour (250g)
• 1 tsp corn starch (for chewiness)
• 1 tsp instant coffee powder (optional, deepens flavor)
• 3/4 tsp baking powder
• 1/2 tsp fine salt
• 7 oz (200g) semi-sweet chocolate chunks

Ingredient Tips & Substitutions

• Butter: Use high-quality unsalted butter for the best browning results.
• Milk Powder: While optional, it adds extra richness to the browned butter.
• Sugars: Light brown sugar keeps the bars moist, but dark brown sugar works too.
• Chocolate: Semi-sweet balances sweetness, but milk or dark chocolate can be used.
• Gluten-Free Option: Substitute with a 1:1 gluten-free flour blend.

Step-by-Step Instructions

Follow these simple steps to create perfect Brown Butter Chocolate Chip Cookie Bars:

1. Preheat your oven to 175°C (350°F) and line an 8×8-inch pan with parchment paper, leaving an overhang for easy removal.

2. Brown the Butter: Melt butter in a saucepan over medium heat. Add milk powder if using. Stir occasionally until the milk solids turn deep amber and the butter smells nutty. Pour into a large bowl and let cool for 10-15 minutes.

3. Whisk Sugars: Add both sugars to the cooled brown butter and whisk until smooth and glossy.

4. Add Eggs: Incorporate the egg and egg yolk, whisking vigorously for a full minute until the mixture is thick, pale, and ribbon-like.

5. Fold Dry Ingredients: Add flour, corn starch, instant coffee powder (if using), baking powder, and salt all at once. Fold gently until just a few streaks of flour remain.

6. Mix in Chocolate: Add chocolate chunks and fold until evenly distributed and no flour streaks remain.

7. Bake: Press dough evenly into the prepared pan. Bake for 18-20 minutes until golden on top but slightly underdone in the center.

8. Cool & Slice: Let cool completely in the pan before slicing into squares.
