Puff pastry puffs up when baking due to the layers of butter and dough. When the pastry is placed in the oven, the butter melts and creates steam, which then pushes the layers of dough apart. This creates the characteristic flaky and airy texture of puff pastry. The high water content in the butter also contributes to the puffing up of the pastry as the steam is released during baking. **
