How often does the letter "i" occur in:
All I could think about when I was making these was the incredibly quotable flick, Mean Girls.
But I’ll be honest, this crack would definitely crack Regina George. And Gretchen Weiners.
After our amazing dinner date at Mellow Mushroom last night, we figured it was time to whip up some dessert. While I used a few different recipes online to remind me how to make this, I also used years of watching my mom make these delicious desserts. I’ve heard it called all sorts of different names. Sugar Bark. Chocolate Crack. Salty Sweet. Crackle. But whatever you call it, it’s addictive. And too easy to make. If you need an easy-to-make food for a crowd you’re trying to please, GO FOR IT!
My saltines were not green. But my lighting was awful, as these were being made at 10 pm.
Preheat the oven to 350 degrees. Line your so called “Jelly roll” pan with the saltine crackers (pack tight, no spaces) and make SURE you don’t have more than one solid row of crackers. If there’s space on the edges, break the saltines to fit the gaps. 
Take the butter. Put it in a medium sauce pan. Melt it at a medium heat. Don’t burn it. Easiest step ever.
Add the cup of dark brown sugar and a dash of vanilla extract (about a teaspoon, maybe a teensy bit more, we just eyed it) to the melted butter in the pan. Stir it at a medium heat until the mixture is a uniform rich brown. This will look divine, smell like warm caramel, and you may be tempted to eat it straight from here. 
Pour the butter sugar vanilla mixture on the crackers, and toss that in the (preheated) oven. Watch it carefully, and when the mixture starts to bubble, take it out.
Sprinkle the chocolate on top of the bubbling sugar crackers. You can let the heat melt it, but I like to take a spatula and spread the chocolate for a more even coating.
We forgot to get the marshmallows, but had marshmallow fluff, so we plopped it all around. However, I always recommend using marshmallows, and sprinkling them around. The fluff’s hard to work with (but, if you’re into getting more on the spoon and your fingers…. by all means.) Put the pan in the fridge and wait it out. I’d say at least 2-3 hours, or overnight.

After refrigerating for a few hours (or overnight, just to be safe), crack the bark up (the foil normally comes off very easily but sometimes you have to pull a bit) into little bite sized treats. Try a piece. 
Voila! I promise, this will go so fast at your next potluck you’ll wonder if you accidentally forgot to bring something.
Ok, now that I’m salivating over crack, I better eat some legitimate breakfast food. A girl can’t live on chocolate, sugar, butter, and saltines alone.
But she can certainly try.
