Chef John's Russian Tea Cakes
As the old joke goes, these Russian tea cakes might not be Russian, but at least they're not cakes. No one knows exactly how these came to be known as Russian tea cakes but, nevertheless, they are quite delicious.
Recipe Summary test
The only tricky thing here is the baking time, since there are so many variables: the size of the dough balls, whether you use a silicone mat or parchment, how light or dark the sheet pan is, etc. These factors can all affect the final time significantly.
I think this cookie tends to get under-cooked, and some recipes call for as little as 12 minutes at 350 degrees F (175 degrees C). I like these fairly golden, so I get that nice brown-butter flavor, and that took me about 20 minutes or so, which is why I gave such a wide range. Start checking at 15 minutes, and proceed from there.
