  • It will take about a minute for them to cook and be golden. Once finished, take each nut out and place onto a cutting board or counter for quick cooling. If there is too much dough around the walnuts, cut off the extra.

Notes

  • An oreshki mold is not hard to come by, but there’s many different cookie mold options out there. Sometimes they’re in an oreshki skillet form, or as an oven mold. 
  • Electrical walnut maker is what I have been using now, they are much easier to work with and turn out great.
