Set oven to 180*C

Mix the flour, Milo, salt, and baking powder together.

Melt your butter in saucepan.

Pour in sugar stir to dissolve.

Remove from heat when done.

Add vanilla extract.

Pour butter mixture into dry ingredients.

Use spatula or wooden spoon to mix. It will be clumpy.

Mix in eggs until well combine.

Pour into pan lined with aluminum foil, and oiled (i used PAM baking spray)

Bake for 20 mins in 180*C oven.

Meanwhile, break up the graham crackers.

When brownie is done, take it out.

Set oven to broil.

Place the marshmallows on the hot brownie.

Broil for about 3-5 mins.

Make sure u watch and not let it burn!

Here I used the regular marshmallows which wasn't as friendly.

I had to push and spread them around after they are soften using the back of a spoon.

The mini ones will save you that trouble.

Sprinkle graham cookies on top of the melted/toasted marshmallows.

Topped with Hersey's chocolate if you like your chocolate melty.

If not wait till brownie cools off completely, then add the chocolate before cutting and serving.
