🍯 Step 1: Preheat the Oven

Set your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat for easy cleanup.

🥄 Step 2: Mix the Wet Ingredients

In a medium bowl, combine the melted butter, brown sugar, and white sugar. Whisk until fully combined and smooth.

Add the vanilla extract and egg yolk only (not the egg white!). Mix well until the mixture is silky and slightly thick.

🧂 Step 3: Stir in Dry Ingredients

Sprinkle in the flour, baking soda, and a pinch of salt. Mix gently with a spatula or spoon until just combined — avoid overmixing!

🍫 Step 4: Add the Chocolate Chips

Fold in the chocolate chips (and any optional add-ins). Your dough should be thick but scoopable.

🍪 Step 5: Scoop and Bake

Scoop 4–6 equal-sized dough balls onto the prepared baking sheet, leaving space between them.

Bake in the preheated oven for 9–11 minutes, or until the edges are golden brown and the centers look slightly underbaked (they’ll set as they cool).

Let them cool on the baking sheet for 5 minutes, then transfer to a rack.
