📖 Instructions

1. **Preheat Oven & Prep Pans:** First things first, preheat your oven to 375°F (190°C). Then, line two large baking sheets with parchment paper. This is crucial for easy cleanup and preventing sticking, ensuring those perfect gooey bottoms.
2. **Combine Dry Ingredients:** In a medium bowl, whisk together 2 ¼ cups (270g) all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt. Give it a good whisk for about 30 seconds to make sure everything is evenly distributed. This ensures your cookies rise properly.
3. **Cream Butter & Sugars:** In a separate, large bowl (or the bowl of a stand mixer fitted with the paddle attachment), beat 1 cup (2 sticks or 226g) unsalted butter, softened, with ¾ cup (150g) granulated sugar and ¾ cup (160g) packed light brown sugar. Beat on medium speed for about 2-3 minutes until the mixture is truly light, fluffy, and noticeably paler in color. Don't rush this step – it incorporates air, which contributes to the cookies' texture.
4. **Add Eggs & Vanilla:** Crack in 2 large eggs, one at a time, beating well after each addition until just combined. Then, stir in 1 teaspoon pure vanilla extract. Don't overmix here; you just want to get them incorporated.
5. **Slowly Add Dry to Wet:** Gradually add the dry ingredient mixture to the wet mixture, beating on low speed until just combined. Be careful not to overmix the dough! As soon as you see no more streaks of flour, stop. Overmixing develops too much gluten, which can lead to tough cookies, and we want soft and gooey, remember?
6. **Fold in Chocolate Chips:** With a sturdy spatula or wooden spoon, fold in 2 cups (340g) chocolate chips. I like to use a mix of semi-sweet and milk chocolate for the best flavor and melt. You can even throw in some chopped chocolate bars for those epic melty puddles. Don't be shy!
7. **Chill the Dough (Optional but Recommended!):** For the absolute best results (and an even gooier center), cover the dough and chill it in the refrigerator for at least 30 minutes, or even up to 24 hours. Chilling helps the flavors meld and prevents the cookies from spreading too much, resulting in thicker, chewier cookies. If you're in a hurry, you can skip this, but trust me, it's worth it!
8. **Scoop & Bake:** Drop rounded tablespoons or use a 1.5-inch cookie scoop (about 1.5-2 tablespoons of dough) onto the prepared baking sheets, leaving about 2 inches between each cookie. If you want truly ridiculous gooey middles, you can press a few extra chocolate chips on top of each dough ball before baking. Bake for 9-12 minutes, or until the edges are golden brown but the centers still look slightly soft and underbaked. This is the secret to that gooey middle! Don't be afraid to take them out when they look a little undone in the center.
9. **Cool & Enjoy:** Remove the baking sheets from the oven and let the cookies cool on the sheets for 5-10 minutes. They will continue to set up as they cool. After that, transfer them to a wire rack to cool completely. Or, if you're like me, snatch one up while it's still warm and the chocolate is ridiculously melty. Pure bliss!
10. **Storage:** Store leftover cookies in an airtight container at room temperature for up to 3-4 days. They're best enjoyed fresh, but a quick zap in the microwave can bring back some of that gooey magic.
