You don't want the first comma there. It should just be:
EXPANDED_NAMES = $(patsubst %,%/%.txt,$(BASE_NAMES))
However...
e> I was hoping EXPANDED_NAMES would expand to:

No. The documentation of the "patsubst" function is clear:
Only the first `%' in the PATTERN and REPLACEMENT is treated this
way; any subsequent `%' is unchanged.

e> a/%.txt b/%.txt c/%.txt

In this particular case you could use:
EXPANDED_NAMES = $(foreach N,$(BASE_NAMES),$(N)/$(N).txt)
