I assume the answer is that other nuts can be used.  I have ground
hazelnut flour and pecan flour.  I wonder about, say, macadamias
and cashews though.  Are they too oily?

I just made delicious cookies using homemade hazelnut flour.  Total cost,
per batch, was $1.40.

According to one of the mavens over on alt.support.diabetes Hazelnuts are
particularly high in things that are good for people with blood sugar
problems.  My non dieting friend stopped by and had a few. She thought they
were delicious and very like almond macaroons.

The only warning I'd include is that they are high calorie, so they could
stall people in the active weight loss phase of a diet whose weight loss has
slowed.
Here's how I did it:

I bought the hazelnuts at Trader Joes.  They were $3.70 a pound.

Hazelnut Cookies  Makes 18

1 cup hazelnut flour
1 tbs vanilla whey protein powder
1/3 cup splenda
1 egg white
1/2 tsp almond extract

Preheat the oven to 300 degrees. Line a cookie sheet with aluminum foil.

Chop hazelnuts very fine. (I used h a little electric "chopper" which I
bought for about $10. It looks like a tiny food processor.)   I used about
1/3 of the pound of nuts and came out with 1 cup of hazelnut flour.

Stir in the rest of the ingredients in the order given.

Use a teaspoon to drop blobs onto the cookie sheet about 1/2 teaspoon in
size.

Bake for 20 - 30 minutes until very lightly browned.

Remove from oven and let cool. Then peel off foil.
