Recipe Ideas

  • Select the suitable peanut butter. You’ll wish to select a clean, creamy peanut butter versus a chunky one. Additionally, keep away from pure peanut butters. They separate, which might intervene with the best way the components to your cookie dough combine collectively.
  • Room temperature butter. The butter within the cookie dough needs to be at room temperature. In any other case it gained’t cream correctly with the peanut butter and sugars (see my subsequent level). The butter within the frosting must also be at room temperature until you need lumpy frosting. So assume forward and let your butter sit out for an hour or so earlier than starting.
  • Don’t skimp on creaming time. When creaming collectively the butter, peanut butter, and sugars, achieve this till the combination has considerably lightened in coloration and turn out to be fluffy.

Mixing previous this level may cause the glutens within the flour to overdevelop and your cookie cake to prove robust.

Cooling it within the pan permits it additional time to agency up in order that it doesn’t disintegrate. Permitting it to chill utterly earlier than including the frosting ensures the frosting stays placed on prime of the cake, slightly than melting off.
