Line an 8x8 inch baking dish with parchment paper. Arrange the pretzel sticks in the bottom of the dish
If needed, microwave the peanut butter until it becomes a drizzle-able consistency. Pour the peanut butter over the pretzels, spreading in an even layer. Sprinkle with peanuts in an even layer. Freeze until solid, about an hour.
Add the caramel to a microwave safe bowl with a splash of water. Microwave in 30 second increments, stirring each time, until the caramel is a smooth, drizzling consistency. Pour over the hardened peanut layer, spreading in an even layer.
Return to the refrigerator or freezer and chill again until firm, about an hour.
Lift the parchment paper out of the baking dish and set the peanut/caramel block on a large cutting board. Use a large, good knife to carefully cut the bars into desired sizes and shapes.
Add the chocolate and coconut oil to a microwave safe bowl. Microwave in 30 second intervals, stirring each time, until smooth.
Use a fork to lower each bar into the melted chocolate, lifting out of the chocolate and letting the excess drip off. Place on a parchment lined baking sheet. Repeat with the remaining bars. Freeze until the chocolate is solid, at least 30 minutes.
Store in the fridge or freezer until ready to enjoy.
