Magnolia Bakery's Peanut Butter Cookies

1 1/4 c all-purpose flour
3/4 tsp baking soda
1/2 tsp baking powder
1/4 tsp salt
1/2 c unsalted butter, softened
1 c chunky style peanut butter
3/4 c sugar (plus extra for sprinkling)
1/2 c firmly packed light brown sugar
1 large egg, at room temperature
1 tablespoon milk
1 teaspoon vanilla extract
1 c peanut butter chips

Directions

Preheat oven to 350 degrees.
In a large bowl, combine the flour, the baking soda, the baking powder, and the salt. Set aside.
In a large bowl, beat the butter and the peanut butter together until fluffy. Add the sugars and beat until smooth. Add the egg and mix well. Add the milk and the vanilla extract. Add the flour mixture and beat thoroughly. Stir in the peanut butter chips. Drop by rounded spoonfuls onto ungreased cookie sheets, leaving several inches between for expansion. Using a fork, lightly indent with a crisscross pattern but do not overly flatten cookies. Lightly sprinkle cookies with sugar. Bake for 10-12 minutes. Do not overbake. Cookies may appear to be underdone, but they are not.
Cool the cookies on the sheets for 1 minute, then remove to a rack and cool completely.
Makes 2-3 dozen cookies.

1/2 tsp vanilla extract
1 c AP flour
1 1/4c cups rolled oats

6 oz semisweet chocolate (I've made it with more, or milk, or whatever - it works)

Directions

Preheat oven to 400F. Butter or parchment (or preferably silpat) two cookie sheets.Cream butter and both sugars together until "smooth and fluffy". Add egg and vanilla and blend thoroughly (I add the vanilla to the egg first). Add everything else to the bowl except the chocolate. Mix on low to incorporate. Fold in the chocolate by hand with a rubber spatula. 12 cookies per sheet, 2tbsp each, flatten. Bake each sheet separately for 9 minutes "until the cookies have spread and puffed slightly, but have not browned". Cool for 10 mins, then put on a rack.
