Directions

Peanut Butter Cookies

Line two rimmed baking sheets with silicone baking mats or parchment paper. Preheat oven to 350°F.

Add the brown sugar and granulated sugar, egg and vanilla to the beaten butters and turn mixer to Speed 4. Beat for an additional 1-2 minutes. Scrape down the sides of the bowl again.

In a separate bowl, stir together the flour, baking soda and salt. Add to the stand mixer bowl and turn to Stir and mix for 30 seconds. Turn the mixer up to Speed 2 and mix for another 30 seconds until fully combined.

Peanut Butter Beaten in the Kitchenaid Mixer

Scoop out the dough into golf-ball sized balls and drop in the bowl of additional granulated sugar. Roll to coat, then place on the prepared baking sheet, about 2 inches apart. Repeat until there are 12 sugar-coated dough balls on each sheet. Gently press the back of the fork gently down on the cookie to flatten and create a criss-cross pattern.

Place in the pre-heated oven and bake for 10-12 minutes until lightly golden brown. Let cool slightly and transfer to a wire rack to continue cooling while you make the frosting.


Marshmallow Frosting

In the bowl of a KitchenAid stand mixer fitted with the paddle attachment, beat together the butter and marshmallow fluff on Speed 4 until light and fluffy, about 3 minutes. Scrape down the sides of the bowl and turn the mixer to Stir.

Slowly add the powdered sugar and beat until incorporated.
