Peabut butter cookies:

I take something like this backpacking sometimes.
From “King Arthur Whole Grain Baking”
1 cup (9.5 oz) smooth peanut butter
1 cup (7 oz) brown sugar
1 large egg
1/4 cup (2 oz) water
2 T (1.5 oz) honey
1 t vanilla
1 t baking soda
1/2 t salt
1 1/2 cups (6 oz) whole wheat flour
1/2 cup (2.5 oz) peanuts finely ground
Preheat oven to 350 F
Lightly grease 2 cookie sheets
Cream everything but flour and nuts. Add flour and beat. Add nuts and beat.
Spoon the cookies on the two sheets. 12 cookies per sheet, or as many as 20. Smash with fork. Have a cup of cold water and dip fork in water occasionally to keep it from sticking.
Bake for 12 minutes.
What you really want to do is try 12 minutes. Just do one cookie. Let it cool. Eat it. If it's too soft increase the time a minute or two. If it's too hard decrease. Repeat until you're happy. Once you get the time for your preference and oven, you can just do the 12 or 20 cookies at a time.
I made these for some family thing, and my nephew said they obviously weren't his mom's (my sister's) because they weren't hard as rocks.
