Fake Nutter Butters, almost (or maybe, DoSiDos?)

I spend a lot of time reading food blogs, especially now that I'm out of work (did you know I got fired because I broke my leg again?). While my mom's at work I'm home alone at her house, and spend a lot of time on her computer. I stumbled on this recipe on tastespotting, and if you haven't noticed, I'm a sucker for a sandwich cookie. Plus, I love peanut butter. I used the recipe from the Joy of Cooking, and found the filling recipe in the NY Times. The cookies aren't as crunchy as real Nutter Butters, but I think they're a good cross between Nutter Butters and DoSiDos (the Girl Scout Cookies), but minus the oatmeal. 

Peanut Butter Cookies

From the Joy of Cooking. Makes enough for about 30 sandwiches. 

1/2 c shortening (I used butter flavor Crisco)

1/2 to 3/4 c peanut butter

1/2 c white sugar

1/2 c brown sugar

1 t vanilla

1 egg

1 1/2 c GF flour mix

1/2 t xanthan gum

1 t baking soda

1/2 t baking powder

1/4 t salt

Preheat oven to 350. Cream the shortening, sugars, and peanut butter for 2-3 minutes until light and fluffy. Beat in the vanilla and egg, then add the flour mix, xanthan gum, baking soda, baking powder, and salt. Mix until combined. Roll small (half of the size of a walnut) balls in granulated sugar (you can skip this step) and place an inch or two apart on a cookie sheet. Bake 9-12 minutes until golden brown. Cool on the cookie sheet, the cookies will be very fragile when hot!
Peanut Butter Filling

From Bouchon Bakery via the NY Times this makes more than you will need, I might halve this next time. 

1 stick butter or shortening

3/4 c peanut butter

1 2/3 c powdered sugar

Cream everything together, beat until fluffy. Spread one side of a cookie with filling, then smoosh another cookie of similar size on top. Repeat.
