I should start off by saying that I did not grow up with Nutter Butters, so I don't really know how close this is to the original Nabisco cookie. Nor have I ever had them from Bouchon Bakery (from which this recipe is adapted). But whatever, they're good! Chewy, buttery, not overly peanutty. It does make for a substantial cookie though. I often cut one in half so as to not feel gluttonous...but then end up eating the other half anyway! In any case, it's also a perfectly good cookie without the filling.
A note on peanut butter: the original recipe recommends using creamy Skippy and then adding in chopped peanuts separately. I always have crunchy peanut butter on hand and see no point in adding chopped peanuts separately. (Caveat: using creamy peanut butter might make the filling easier to spread.) Bottom line: use what ever you like...creamy, creamy with separately added peanuts, crunchy or hell, crunchy with even more peanuts added in!
1 cup (2 sticks) butter, at room temperature
1/3 cup peanut butter
1/2 cup sugar
1/2 cup brown sugar
1 teaspoon vanilla
1 cup flour
1 teaspoon baking powder
2 teaspoons baking soda
(coarsely chopped peanuts)
1 + 1/4 cups rolled oats (orig. recipe calls for "quick cooking"but I only ever have "old-fashioned" on hand)
Heat over to 350 degrees. Beat together butter, peanut butter, sugars, egg & vanilla until smooth and creamy, about 4 minutes. Stir in dry ingredients. Drop rounded teaspoons (or larger if you want) on parchment-lined baking sheets and bake for about 10 minutes, until cookies have spread and turned very light golden brown. Remove from oven and cool on cookie sheet for about 5 minutes, then cool completely on a rack.
1/4 cup (1/2 stick) butter
1/4 cup peanut butter
3/4 cup confectioners' sugar
Beat all ingredients together until smooth. Spread a thin layer of filling (about 1/8 inch) on the underside of a cookie and sandwich with another.
