For an even more intense chocolate flavor, use dark cocoa powder. Toasting the pecans enhances their nutty flavor. Spread them on a baking sheet and bake for 5-7 minutes at 350°F (175°C), or until fragrant. For a smoother caramel drizzle, warm the caramel syrup slightly before using. Store the brownie bites in an airtight container at room temperature for up to 3 days.
