How to Make Chocolate Chip Cookies Incredibly Soft and Fluffy: 7 Science-Backed Secrets

5. Chill the Dough

Why it works: Cold dough melts more slowly in the oven, preventing overspreading and resulting in thicker, fluffier cookies. Chilling also improves flavor.
Pro tip: Refrigerate dough for 2–4 hours, or overnight if you can.

6. Add an Extra Egg Yolk

Why it works: Egg whites provide structure but can dry out cookies. Extra yolk adds richness, tenderness, and chewiness without making cookies cakey.
Pro tip: Use 1 whole egg plus 1 extra yolk in a standard recipe.

7. Slightly Underbake

Why it works: Cookies continue cooking on the baking sheet after removal from the oven. Taking them out when the edges are set but the centers still look soft locks in ultimate softness.
Pro tip: Remove cookies when edges are golden and centers appear slightly underdone—they’ll firm up as they cool.

The Ultimate Soft & Fluffy Chocolate Chip Cookie Recipe

Combine all seven secrets below for guaranteed bakery-style perfection.

Ingredients:

  • ¾ cup (1.5 sticks) unsalted butter, melted and cooled

  • 1 cup packed dark brown sugar

  • ½ cup granulated sugar

  • 1 large egg + 1 egg yolk, at room temperature

  • 2 tsp vanilla extract

  • 2 ¼ cups all-purpose flour

  • 2 tsp cornstarch

  • 1 tsp baking soda

  • ½ tsp salt

  • 2 cups chocolate chips (semi-sweet or milk)

Instructions:

  1. Whisk Wet Ingredients: In a large bowl, combine melted butter, brown sugar, and granulated sugar. Add the egg, extra yolk, and vanilla; whisk until smooth and glossy.

  2. Combine Dry Ingredients: In a separate bowl, whisk together flour, cornstarch, baking soda, and salt.

  3. Mix Together: Fold dry ingredients into wet ingredients with a spatula until just combined. Stir in chocolate chips.

  4. Chill: Cover and refrigerate dough for 2–4 hours or overnight.

  5. Bake: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper. Scoop dough (about 3 tbsp per cookie) onto the sheet, leaving 2 inches between each.

  6. Bake to Perfection: Bake 10–12 minutes until edges are set and golden, but centers still look soft. Cookies will finish setting as they cool.

Pro Tip: Tap the baking sheet on the counter 2–3 times after removing from the oven to create slightly wrinkled tops, just like bakery cookies.
