Pretzel Christmas Crack is the best holiday treat! This addictive combination of salty pretzels, rich toffee and chocolate is sure to be a hit at any party or gathering.
Preheat the oven to 400 degrees Fahrenheit. Line a 10×15×1 inch baking sheet with aluminum foil and spray with pan spray.
Whisk together the butter, brown sugar, and salt in a saucepan over medium-high heat, and let it boil for 4-5 minutes to make the toffee mixture.
Stir the pretzels into the toffee mixture and pour it onto the prepared baking sheet. Spread out the pretzels as evenly as possible, but it's alright if it’s not very even. Bake for 5 minutes.
Remove the baking sheet from the oven, immediately sprinkle the chocolate chips evenly over the toffee with chocolate chips, and let it sit for about 2 minutes until all the chocolate has melted.
Spread the chocolate over the pretzels and toffee and sprinkle with flakey sea salt. Let it cool completely before cracking into pieces and serving.
