I adjusted this recipe from one I found online. This was my first attempt to bake gluten-free cookies. These contain no flour whatsoever and are a different texture than regular peanut butter cookies. But they are cookies.
2 cups crunchy peanut butter
2 cups white sugar
4 beaten eggs
1/2 tsp. pure vanilla (make sure it is gluten-free)
2 cups chocolate chips (I made half without)
Mix peanut butter and sugar. Add eggs and vanilla. When fairly smooth, mix in chocolate chips. Dough will look and feel glossier than regular dough.
Drop by spoonfuls onto greased cookie sheet. Bake at 375 degrees for 10 minutes or so. Remove from oven and let cool on cookie sheet for 5-10 minutes before removing to cooling rack.
The batch without the chocolate chips was chewier and they flattened out more. But nobody turned them down.
