Ingredients

For the peanut butter cookies

  • 1 3/4 cups unbleached all-purpose flour, plus more for rolling
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 6 tablespoons unsalted butter, at room temperature
  • 1/2 cup plus 1 tablespoon lightly packed dark brown sugar
  • 3/4 cup plus 1 tablespoon confectioners' sugar
  • 1/2 cup creamy peanut butter
  • 1/2 cup vegetable oil
  • 1 1/2 teaspoons vanilla extract
  • 1 large egg

For the milk chocolate filling

  • 6 ounces milk chocolate, roughly chopped
  • 1/2 cup creamy peanut butter
  • 1/4 cup confectioners' sugar
  • 1/4 teaspoon kosher salt
  • 3/4 cup heavy cream

Instructions

Make the peanut butter cookies

  • Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
  • In a large bowl, sift together the flour, baking powder, baking soda, and salt.
  • In the bowl of an electric mixer fitted with the paddle attachment, beat the butter, brown sugar, and confectioners' sugar on medium-high speed until light and fluffy, about 2 minutes. Add the peanut butter and beat to combine, scraping down the sides of the bowl as needed. With the mixer on low speed, slowly add the oil, vanilla, and egg and beat until just combined, about 20 seconds. Add the flour mixture, beating just to combine.
  • Lightly flour the palms of your hands, and roll the dough into balls about 1/2 inch in diameter. Place them about 1 inch apart on the prepared baking sheets. Bake, rotating the sheets halfway through, until the cookies are golden brown on the edges, about 12 minutes.
  • Move the baking sheets to wire racks and let cool completely.

Make the milk chocolate filling

  • Combine the chocolate, peanut butter, confectioners' sugar, and salt in a medium bowl. In a small saucepan, bring the cream to a boil. Remove the cream from the heat and pour it over the chocolate mixture. Stir with a spatula until the chocolate is completely melted.
  • Set the bowl in an ice bath, or chill it in the refrigerator, until the filling has cooled to room temperature and is thick enough to spread.

Assemble the peanut butter cookies

  • Using an offset spatula, spread 1 teaspoon of the milk chocolate filling over the flat sides of half of the cookies. Sandwich with the remaining cookies, flat sides together.
