Drop in eggs one by one, making sure each one's mixed in good before adding another. Then throw in your vanilla.

Slowly add your dry mix to the wet stuff, mixing on low just till it forms dough. Don't mix too much. You can swirl in marshmallow cream now or wait till after cooling the dough.

Wrap up your dough and stick it in the fridge for at least an hour so it's easier to work with and won't spread too much when baking.

About 20 mins before you start baking, turn your oven to 175°C (350°F). Get two baking sheets ready with parchment or silicone mats.

Scoop out cold dough and roll into balls. Put them on your sheets about 2 inches apart. Push a little dent in each ball, add a teaspoon of marshmallow cream, and swirl it with a toothpick.

Stick them in the hot oven for 10-12 mins until the edges look done but centers stay soft. If you want, add more marshmallow halfway through for extra gooey centers.

Leave cookies on the hot sheet for 5 mins before moving to a rack. This lets the marshmallow set and makes them easier to pick up.
