Preheat and Prepare:

1. Begin by preheating your oven to 350°F (175°C). This ensures your oven is at the right temperature for an even bake.
2. Line your rimmed sheet pan with aluminum foil, a crucial step for easy cleanup. Lightly grease the foil with butter for a non-stick surface.

Assemble the Base: 3. Arrange the graham crackers on the prepared baking sheet. Break them as needed to fit the pan, creating a solid layer as the foundation of your bark.

Create the Caramel Pecan Mixture: 4. In a medium saucepan, combine butter, brown sugar, chopped pecans, and salt. This blend will form the rich, caramelized layer.

5. Cook over medium heat, bringing the mixture to a boil. Allow it to cook for 2 minutes while stirring constantly. This process melds the flavors together and achieves a smooth consistency.

Add the Final Touch: 6. Remove the saucepan from heat and stir in the vanilla extract, infusing the mixture with its sweet, aromatic flavor.

Combine and Bake: 7. Pour the hot pecan mixture over the graham crackers, spreading it to the edges with a spatula. Ensure the pecans are evenly distributed and the crackers are completely covered.

8. Bake in the preheated oven until the mixture is bubbly, which should take about 10 minutes.

Cool and Enjoy: 9. After removing from the oven, let it cool completely. This step is vital for the bark to set and develop the perfect texture.

10. Once cooled, break the bark into pieces. The size and shape are up to you – whether large shards for a dramatic presentation or smaller bites for easy snacking.
