Make a base for the s'mores using the powdered biscuits cocoa powder and the butter. Spoon them in a muffin pan lined with a muffin liner.
Press it with the help of your fingers nicely making a dent in between. Bake these at 180 degrees for about 15-18 mins.
Remove them and place a chocolate chunk in the dent we made, then top it up with the marshmallows so as to cover it up. If you like to make it more chocolaty, top it up with one more chocolate chunk on the marshmallows. Keep it back in the oven just for 2 mins until the marshmallows melt.
Enjoy them immediately when they are piping hot for that awesome taste.
