Gently crush ramen noodles before opening package. Open package and discard flavoring packet. Sauté crushed noodles, pecans, and almonds in butter in a large skillet over medium heat until toasted. (Be careful not to crush noodles too finely while sautéing.) Pour noodle mixture into a large bowl to cool.
Melt white chocolate morsels according to package directions. Pour melted chocolate over cooled noodle mixture, tossing gently to coat. Drop candy mixture by rounded tablespoonfuls onto wax paper; let stand until firm (about 45 minutes). Store clusters in an airtight container at room temperature.
Note: It's important to melt white chocolate according to package directions. If heated too quickly or at too high a temperature, the morsels will not melt properly. We recommend using microwave directions for melting.
