BUTTER STICKS TO CUPS RECIPES

Steps:

• Preheat the oven to 350 degrees F. Line cupcake pans with paper liners.
• In the bowl of an electric mixer fitted with a paddle attachment, cream the butter and 2 sugars on high speed until light and fluffy, approximately 5 minutes. Lower the speed to medium, add the eggs 1 at a time, then add the vanilla and mix well. In a separate bowl, whisk together the buttermilk, sour cream, and coffee. In another bowl, sift together the flour, cocoa, baking soda, and salt. On low speed, add the buttermilk mixture and the flour mixture alternately in thirds to the mixer bowl, beginning with the buttermilk mixture and ending with the flour mixture. Mix only until blended. Fold the batter with a rubber spatula to be sure it's completely blended.
• Divide the batter among the cupcake pans (1 rounded standard ice cream scoop per cup is the right amount). Bake in the middle of the oven for 20 to 25 minutes, until a toothpick comes out clean. Cool for 10 minutes, remove from the pans, and allow to cool completely before frosting.
• Frost each cupcake with Peanut Butter Icing and sprinkle with chopped peanuts, if desired.
• Place the confectioners' sugar, peanut butter, butter, vanilla, and salt in the bowl of an electric mixer fitted with a paddle attachment. Mix on medium-low speed until creamy, scraping down the bowl with a rubber spatula as you work. Add the cream and beat on high speed until the mixture is light and smooth.

Steps:

• Whisk together flour, baking powder, and salt in a small bowl.
• Beat together butter and sugar in a large bowl with an electric mixer at medium-high speed until pale and fluffy, about 3 minutes in a standing mixer (preferably fitted with paddle attachment) or 6 with a handheld. Beat in egg and vanilla. Reduce speed to low, then add flour mixture and mix until just combined.
• Form dough into a 12-inch log (2 inches in diameter) on a sheet of plastic wrap and roll up dough in plastic wrap. Chill dough on a baking sheet until firm, at least 4 hours. (To roll cookies into balls, see cooks' note, below.)
• Put oven racks in upper and lower thirds of oven and preheat oven to 375°F.
• Cut enough 1/8- to 1/4-inch-thick slices from log with a heavy knife to fill 2 ungreased large baking sheets, arranging slices about 1 inch apart (chill remainder of log, wrapped in plastic wrap). If garnishing with coarse sugar, sprinkle slices with it.
• Bake cookies, switching position of sheets halfway through baking, until edges are golden, 12 to 15 minutes total. Cool on sheets 3 minutes, then transfer with a metal spatula to racks to cool completely. Make more cookies with remaining dough on cooled baking sheets.
