Chocolate Whoopie Pies with Fresh Strawberries and Bruleed Marshmallows - butter

Method

• Preheat the oven to 425 degrees F. Line 2 baking sheets with silicon mats or parchment paper and set aside.
• For the cookies: Beat the butter and sugar with a hand mixer until light and fluffy.
• Add the egg and vanilla until just incorporated.
• Scrape down the sides of the bowl.
• In a separate bowl, whisk together the flour, cocoa powder, baking soda, salt and baking powder.
• In a third bowl, combine the milk and sour cream.
• Add half of the milk mixture to butter mixture while mixing on low speed.
• Then add half of the flour mixture and mix until incorporated.
• Repeat the process.
• With a measured scoop, portion out the batter into small rounds on the prepared baking sheets, spaced at least an inch apart.
• You can make the cookies whatever size you like; I like mine a bit big so I use a 4-ounce ice cream scoop.
• Bake until the tops lightly spring back when touched, 8 to 10 minutes.
• Remove from the oven and allow to cool completely.
• For the filling: Add the sliced strawberries to a bowl and sprinkle with the granulated sugar and let sit for 15 minutes.
• Preheat the oven to a broil and set a rack 6 inches from the broiler.
• When the cookies are cooled, place them round-side down and then top half of them with sliced strawberries.
• Press 3 marshmallows together using the palm of your hand, until mostly flattened, and then place them on the other half of the cookies.
• Place the marshmallow-covered cookies back on the baking sheets and place under the broiler to let the marshmallows char and soften until lightly golden on top, 1 to 4 minutes.
• Keep an eye on them as they can burn quickly.
• For assembly: Top the strawberry side of the cookie with one of the marshmallow cookies, gently press together and then stand back and marvel at your creation.
