Baking Chilled Dough — What Changes?
Chilled dough enters the oven cold, with firmer butter and a more stable structure.
Before baking, chilling allows:
• Butter to firm up
• Flour to fully absorb moisture
• Gluten to relax
When baked:
• Butter melts later
• Dough holds its shape longer
• Structure sets earlier
This often results in:
• Less spread
• Thicker centers
• More defined cookie shape
Chilled dough sets first, then spreads.
That timing difference is what changes cookie structure.
