I vow here and now to only make this when I'm bringing it to someone else's house. Dangerous.
First, the ingredients:
2 sticks of butter
1 cup of light brown sugar
1 bag of pretzels (you'll use about 3/4 of the bag)
12 ounce bag of chocolate chips
Two quick notes on ingredients, I would use the "snaps" pretzels because you'll get a more even covering of the bottom of the pan. Also, if there is a Trader Joes within 20 miles of you drive there and stock up on chocolate chips. $1.99. That's right, $1.99.
Preheat the oven to 400.
Line a baking sheet with aluminum foil, cover with pretzels (you don't have to do the super neat grid I did, it just made me feel all aligned and happy).
In a medium saucepan melt the butter over medium-low heat. When it begins to bubble add the brown sugar. Stirring occasionally let the butter/sugar mixture meld together and brown. This should take about 3 minutes. Do NOT let it boil, you will have sticky goo that is no good. And if you can afford to lose two sticks of butter to a failed experiment why are you even reading a DIY blog? (Call me, I'll make the bark, you can pay me and pass it off as your own, win, win.)
When you have a nice, brown caramel pour it over the pretzels, slowly and evenly. You can then use a spatula to spread it out, you have to work quickly and gently. It hardens fast so even pouring is the best method.
Bake the sheet for 5 minutes.
Remove the sheet from the oven and sprinkle the whole bag of chocolate chips evenly over the mixture.
Place back in the oven for about 45 seconds. If you let it sit there too long the chocolate will burn.
Remove from the oven and use a silicone spatula or the back of a spoon to evenly spread the chocolate over the top.
Sprinkle with sea salt and refrigerate for a minimum of 1 hour.
Break in to pieces and put in a cute little box lined with parchment paper.
Perfect hostess gift.
