Creating Pecan Pie Bark is straightforward. Just follow these simple steps:

1. Prepare the Pan: Line a baking sheet with parchment paper, extending it slightly over the sides for easy removal.
2. Toast the Pecans: In a skillet, toast the pecans over medium heat until fragrant. This should take about 5-7 minutes.
3. Melt the Dark Chocolate: In a microwave-safe bowl, add the semi-sweet chocolate chips. Microwave in 30-second intervals, stirring in between until fully melted.
4. Spread the Chocolate: Pour the melted chocolate onto the lined baking sheet. Using a spatula, spread it evenly to form a thin layer.
5. Layer : Drizzle the dulce de leche or caramel sauce over the melted chocolate. Use a knife or spatula to swirl it through the chocolate.
6. Add Pecans: Sprinkle the toasted pecans evenly over the chocolate-caramel mixture. Gently press them down with the back of a spatula.
7. Melt the White Chocolate: In a separate bowl, melt the white chocolate chips in the microwave using the same method as before.
8. Drizzle: Once melted, drizzle the white chocolate over the bark and use a toothpick to create a marbled effect with the dark chocolate.
9. Chill: Place the baking sheet in the refrigerator for about 30 minutes or until the bark is set.
10. Break into Pieces: Once set, lift the parchment paper to remove the bark from the baking sheet. Break it into pieces of your desired size.
