For an extra touch, consider adding a sprinkle of finely chopped nuts or a drizzle of white chocolate over the toasted sliders. Ensure the cream cheese is thoroughly softened to prevent lumps in the filling. Keep a close eye on the sliders during the final baking stage to prevent burning. The toasting time may vary depending on your oven. For a richer flavor, use a high-quality European-style butter. Serve warm for the best experience!
