S'mores cupcakes!

I made s'mores cupcakes today! They consist of graham cracker cupcakes, marshmallow icing, and chocolate drizzle!
here ya go:

graham cracker cupcakes
1 cup of flour
1/2 cup of graham cracker crumbs
1 1/2 teaspoon of baking powder
1/4 teaspoon of salt
1 stick of butter, room temperature
1 cup of sugar
2 eggs
1/2 teaspoon of vanilla extract
1/2 cup of milk

1) If butter is not already room temperature, set it out. Preheat oven to 400 degrees. Spray your cupcake pan with non-stick spray. Line with papers if you want to use them. (Cupcakes do not rise well, just enough to go over the paper and stick to the pan, so make sure to spray it. If you forget, you can use the back of a spoon to un-stick the cupcakes.)
2) Put 3 full graham crackers in to a plastic bag and smash until crumbs are as small as possible (check in measuring cup, but this should equal about 1/2 cup)
3) Combine flour, graham cracker crumbs, baking powder, and salt in the mixing bowl. Stir until mixed well.
4) Gradually beat in butter.
5) Beat in sugar thoroughly.
6) Beat in eggs, sugar, and milk one at a time.
7) Add vanilla and mix until just combined.
8) Bake for about 15-17 minutes. Let cool before frosting.

marshmallow icing
4 large egg whites
1 cup of sugar
1/4 teaspoon of cream of tartar
1 teaspoon of vanilla extract

This is what you're supposed to do:
1) Place all ingredients except vanilla into a metal heatproof bowl from the mixer. Place bowl over a saucepan of simmering water and whisk until sugar is dissolved, about 3-4 minutes.
2) Remove bowl from heat and attach to mixer. Using whisk attachment, whisk for 5-7 minutes, gradually moving from low-high, until peaks form. Add vanilla and whisk until just combined.
3) Use immediately.

and this is what I did (and why my icing looks deliciously melty and tastes very marshmallowy)
1) Place all ingredients except vanilla into a glass bowl over a saucepan of simmering water and whisk until sugar is well blended (about 5 minutes).
2) Pour sugar/egg/etc. combination in to the mixer bowl. Using the flat attachment, mix for 13 minutes, gradually moving from low-high. Get annoyed that it isn't peaking and get out the hand mixer with the whisk attachments and mix for about 4 minutes. Glare at the lack of peaks. Add vanilla, taste test, and decide to use anyway.
3) Use immediately.

then...
Break a full Hersey bar into pieces and microwave in a small microwave safe bowl for 30 seconds. Stir, and drizzle on to cupcakes. (Use 1 1/2 bars for 30 seconds if you want more chocolate). Break apart another full Hersey bar and place pieces onto cupcake top.
Enjoy!

Let me know what you think! Which icing recipe did you go with? Which did you prefer? Have you tried another recipe for s'mores cupcakes?

(I combined 2 recipes for this. The original cupcake recipe can be found here and the original icing recipe came from my grandmother.)
