Chocolate Caramel Pretzel Bark

1. Begin with a parchment lined baking sheet. To make sure the chocolate bark doesn't stick to it, you may lightly spray the parchment or wax paper.
2. Melt the semi-sweet chocolate. This can be done in a double-boiler or in the microwave. If you choose the microwave, start off with a microwave-safe bowl. It is important when melting chocolate to reduce the microwave power to 50%. Cook the chocolate in 30-second increments, stirring well after each increment, until completely melted.
3. Press the pretzels into the chocolate immediately so the pretzels will adhere to the chocolate as it hardens.

To make Homemade Caramel:

1. In a medium saucepan, heat sugar over medium heat, stirring constantly. The sugar will begin to form clumps and will turn into an amber color. Keep stirring. Watch carefully as the sugar can easily burn.Once sugar is completely melted, add the butter. The butter will bubble so be careful.Stir the butter into the caramel until it is completely melted. Use a whisk to stir the sugar and butter. Drizzle the heavy cream into mixture and stir.Let it boil for 1-2 minutes. Remove from heat and stir in sea salt. Let set up.  Once the caramel is done, pour over the pretzels. You may not use all of the caramel. 
2. If you are using packaged caramels, melt according to the package instructions.
3. Melt the milk chocolate (see step #2). Use a spoon or flat spatula to pour over the caramel. Spread the milk chocolate almost to the edges. Cover and place in the refrigerator to chill for several hours. If you want to speed up the process, it can be placed in the freezer.Cut into squares and serve.
