I am using the same recipe with a handful of chocolate chip added to the muffin.
Just to experiment the marshmallow thingy, I now cut them into small bits. I was anticipating that soft chewy bite.
Experiment 1: place them at the bottom of the muffin cup
Experiment 2: place them at the middle of the muffin cup
And you know what happen???
For those that I placed at the bottom of the muffin cup, the marshmallow melted, leaving behind pot-holes as the only evidence of "been there done that".
For those that I placed at the middle of the muffin, the marshmallow still managed to wiggle its way to the top of the muffin... but this time round, I get a nice bloom...
