Do-Si-Dos A.k.a. Peanut Butter Sandwich Cookies

• 2 14 cups all purpose flour
• 2 tablespoons baking soda
• 1 tablespoon baking powder
• 12 teaspoon salt
• 1 12 cups unsalted butter, room temperature
• 34 cup chunky peanut butter
• 1 cup brown sugar
• 1 cup sugar
• 3 large eggs
• 1 teaspoon vanilla extract
• 1 12 cups quick-cooking oats (not instant or regular)
• 1 12 cups creamy peanut butter, room temperature
• 12 cup butter, room temperature
• 14 cup confectioners sugar

1. Preheat oven to 350F.
2. Start with the cookies.
3. In a medium bowl, whisk together the flour, baking powder, baking soda and salt.
4. In a large bowl, cream together butter and peanut butter.
5. Beat in the sugars until fluffy, then add in the eggs one at a time, waiting until each is fully incorporated before adding the next.
6. Stir in vanilla extract.
7. Working at a low speed, mix in the flour, followed by the oats (if you dont have quick-cooking, pulse whole rolled oats in the food processor to chop them up a bit).
8. On a parchment-lined baking sheet, drop teaspoonfuls of batter (roughly 3/4-in.
9. sized balls), leaving about 2 inches between each to allow for spread.
10. Bake for about 10 minutes, until cookies are a light golden brown.
11. Cool on baking sheet for 5 minutes, making small holes in 1/2 of the cookies (for the tops of the sandwiches) before they set up.
12. Transfer to a wire rack to cool completely.
13. Once cookies have cooled, make the filling.
14. In a large bowl, cream together smooth peanut butter, butter and confectioners sugar until very smooth.
15. Spread 2-3 tsp onto half of the finished cookies and sandwich with the remaining halves.
16. If you chose to make yours with GS-lookalike holes in some of the cookies, use these as the tops of the sandwiches.
17. Store in an airtight container.
18. Note: Use unsalted butter with this recipe, as different brands of peanut butter can vary hugely in salt content and its possible youll end up with a too-salty cookie with the salted butter, salted peanut butter and added salt.
19. If you must use salted butter and are using brand of peanut butter that seems a bit salty, you can always reduce or eliminate the added salt.
20. Personally, I like the salty sweet combination with peanut butter, but its only fair for me to give a little warning just in case!
