@tammyscookiecompany: Soft fillings like jams, spreads, caramel, or Nutella can make cookies spread too much—or leak out completely during baking. Sometimes fillings like Nutella can even thicken while baking. The heat causes the sugars to concentrate and the cocoa solids to absorb moisture, which can change the consistency and make the center less gooey than expected. Instead of stuffing the dough before baking, try this: ✨ Bake the cookie first ✨ Pipe the filling in while the cookie is still hot The center is still soft and malleable, so it naturally makes room for the filling without breaking the structure of the cookie. Want to seal the hole? Just add a little chocolate on top. The heat from the cookie will melt it slightly and seal everything perfectly.
