Peanut Butter and Chocolate Marshmallow Surprise Cookies
Your favorite dessert combo is made into a decadent peanut butter and chocolate treat, and has a hidden marshmallow right under the rich peanut butter frosting.
Heat oven to 375ºF. Line two baking sheets with parchment; set aside.
In a bowl sift together the flour, cocoa powder, baking soda, and salt; set aside.
In the bowl of an electric mixer fitted with the paddle attachment combine the butter and sugar on medium-high speed until pale and fluffy, about 2 minutes. Reduce speed and mix in egg, milk and vanilla. Mix in flour mixture, ½ cup at a time, until combined; scraping down the sides and bottom of the bowl as needed.
Use a 1¾ inch cookie scoop (#40 size) to drop 1½ tablespoons dough onto prepared baking sheets, spacing about 2 inches apart. Bake, rotating sheets halfway through, until cookies are just set, 8 minutes.
Remove and immediately press a marshmallow half on top of each cookie. Bake again until marshmallows begin to melt, 2 minutes more. Let cool completely on baking sheets on wire racks.
For the peanut butter frosting:
Mix together the peanut butter and melted butter in a mixing bowl with an electric mixer. Add the confectioners' sugar and salt and mix until completely combined. Add the milk and beat until a smooth frosting forms. Beat until fluffy and smooth, about 30 seconds. Smooth with a spatula.
Spread about 1 tablespoon frosting on top of each cookie to cover marshmallow. Let stand until set, about 10 minutes. Cookies can be stored in single layers in airtight containers at room temperature for up to 2 days.
Store any remaining frosting in a container in the fridge for up to a week.
