How to stuff a cookie so the filling stays inside
Stuffed cookies leak for one reason: the filling was too soft and the seam was not closed. Both are easy to fix.

A stuffed cookie should cut open in three clear layers — cookie, filling, cookie. When it goes wrong, the filling escapes out of the side during baking and welds itself to the tray. Bobbie's nine stuffed cookie recipes all use the same method, and once you know it, it applies to any filling you like.
Why does the filling need to be frozen first?
Because a soft filling melts before the dough around it has set. Bobbie portions the filling into small mounds, freezes them until they are firm enough to handle, and only then wraps dough around them. Cream cheese fillings, jam, hazelnut spread and caramel all get this treatment; the freezing time differs by filling and is written on each recipe page.
Frozen filling also lets you work quickly with warm hands without the whole thing turning into a mess on the counter.
How much dough goes around it?
Bobbie uses an ice-cream scoop for the dough ball and a teaspoon of filling sealed inside. Flatten the dough into a fairly thick disc, sit the chilled filling in the centre, bring the dough completely up and around it, and pinch every seam closed before rolling it gently back into a ball.
Every seam matters. One unclosed pinch is the gap the filling finds. Do not stretch the dough thin to make it reach — take a little more dough instead.
How do you know when they are done?
By looking at the tops, not by a timer alone. Bobbie judges these by visual inspection, which is why her recipes tell you what to look for rather than promising an exact minute — ovens differ more than recipes admit.
Bake on parchment paper, or lightly spray the tray if you have no parchment. Then cool the cookies on a cooling rack on the kitchen counter for 20 to 30 minutes. This is not optional: a stuffed cookie moved too early tears open under its own weight.
Can you make them gluten free, and what about allergens?
A 1:1 gluten-free flour blend works in place of regular flour. On allergens, be straightforward with people: some fillings contain nuts or dairy, so say which one you made. The FDA's food allergy pages are a sensible reference if you are cooking for someone who has to avoid a specific ingredient.
