To create your delicious Pecan Pie Bark, follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy removal.
2. Melt Butter: In a medium saucepan, melt the unsalted butter over medium heat. Stir in the brown sugar and corn syrup until well combined.
3. Add Vanilla: Remove the saucepan from heat and mix in the vanilla extract. This step enhances the flavor of your bark.
4. Combine Pecans: Stir in the chopped pecans until they are evenly coated with the buttery mixture.
5. Spread Mixture: Pour the pecan mixture onto the prepared baking sheet and spread it out evenly. Use a spatula to ensure it’s evenly distributed.
6. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until golden and bubbly. Keep an eye on it to prevent burning.
7. Add Chocolate: Remove from the oven and immediately sprinkle the chocolate chips over the hot mixture. Let it sit for a few minutes to allow the chocolate to melt.
8. Swirl Chocolate: Once the chocolate is melted, use a spatula to swirl it through the pecan mixture for a marbled effect. If you’re using toffee bits, sprinkle them on top at this stage.
9. Cool and Slice: Allow the bark to cool at room temperature for about 10-15 minutes. You can also refrigerate it for quicker cooling. Once cool, cut it into squares or break into pieces.
10. Sprinkle Salt: Optionally, sprinkle a little sea salt on top for a sweet-and-salty finish before serving.

These steps will guide you in effortlessly creating an incredible Pecan Pie Bark that both you and your guests will adore.
