Line a large baking sheet with parchment paper. Make sure the parchment covers the entire surface. This prevents the bark from sticking and makes removing the finished dessert much easier.

Place the pecans in a dry skillet over medium-low heat. Toast them for three to five minutes, stirring often. Remove them when fragrant and lightly browned, then let them cool.

Add the chocolate chips to a microwave-safe bowl. Heat them in short intervals, stirring between each one. Continue until the chocolate becomes smooth and completely melted.

Pour the melted chocolate onto the prepared baking sheet. Use a silicone spatula to spread it into an even layer. Aim for roughly one-quarter inch thickness.

Add butter, brown sugar, cream, maple syrup, cinnamon, and salt to a saucepan. Cook over medium heat while stirring until the butter melts and the sugar dissolves.

Bring the mixture to a gentle boil. Continue cooking for about two minutes while stirring constantly. Remove the saucepan from the heat and carefully stir in vanilla extract.

Stir the toasted pecans into the warm caramel mixture. Make sure the nuts become evenly coated. Work carefully because the mixture will be very hot.

Spoon the warm pecan mixture over the chocolate layer. Spread it gently with a spatula. Try to distribute the pecans evenly so every piece gets plenty of crunchy topping.

Place the baking sheet in the refrigerator. Chill for about one hour, or until the chocolate and caramel become firm. Do not move the bark while it sets.

Remove the chilled bark from the refrigerator. Peel away the parchment paper carefully. Break the bark into small, uneven pieces using your hands or a sharp knife.

Arrange the bark on a dessert plate or serving tray. Serve immediately or keep it chilled until needed. The bark tastes especially delicious with coffee or warm tea.
