My guess would be multi-pass milling with a very fine milling bit for
the final pass.

The only alternative I can think of would be to produce the faces of the
cubes (the "frames" and letters) as separate sheets of wood, and glue
them onto the cubes; in that case the grooved pattern could also serve a
technical purpose, namely to improve the bonding.
