Milo FunnyFaces Cookies

Was directed to this recipe by BH & decided to give it a try tonite. However, with MIL nagging abt giving d 2 toddlers too much chocolate, I decided to try replace with marshmallows instead. But what a horror when I checked d cookies 10mins into d baking process – those cookies that r stuffed with marshmallows r cracking open & marshmallows r flowing out of d dough! (pic1) Yuk!
And even after lowing d temp from 140C to 130C, I noticed that my entire 1st batch was burned only after 15mins in d oven! Argh!
So in d end, I have to throw away d entire 1st batch. For d 2nd batch, I decided to just follow d recipe & insert chocolate chips into d dough. However, I lower d temp in order to ensure no burned cookies again.
