Preparation

Step 1

Preheat the oven to 350 degrees and line an 8x8" baking pan with parchment paper sprayed lightly with nonstick spray.
In the bowl of a standing mixer, cream together the butter and brown sugar for 1 minute. Add the peanut butter and mix for 30 seconds. Add the egg and vanilla and beat until smooth, scraping down the sides.
In a medium bowl, whisk together the flour, baking powder and salt. Add to the wet ingredients and mix until combined. Fold in the peanut butter chips.
Press the dough into the pan and bake for 25-28 minutes, remove from the oven and top with marshmallows then bake an additional 1-2 minutes.
Remove the pan from the oven and allow to cool for 10 minutes then add dollops of frosting and allow to sit another few minutes to soften the frosting. Spread gently with a spatula and serve.

For the frosting:
In a large bowl, using a hand mixer, beat the butter and cocoa. Add the powdered sugar, cream and vanilla and beat until smooth.
