Makes 32 cookies or 16 cookie sandwiches
For peanut butter filling:
Preheat oven to 350 F. Line 2 baking sheets with parchment or silicone mats and set aside.
Place 1 cup of chocolate chips and butter in a glass bowl and place in the microwave for 30 second intervals, stirring between each one, until melted & smooth. Set aside.
In an electric mixer fitted with the paddle attachment, combine eggs,
sugar and vanilla & mix on medium speed until pale and creamy, 5-7
minutes. Add in flour, baking powder, melted chocolate mixture,
remaining chocolate chips and continue beating until fully
incorporated. Drop generously rounded tablespoons of the batter onto
prepared baking sheets, spacing 1-2 inches apart. Bake for about 9–11
minutes until cracked on top. Cool cookies completely on wire racks.
While the cookies are cooling, make the peanut butter filling. In an electric mixer fitted with the paddle attachment, beat cream cheese and confectioner's sugar together until pale and fluffy. Add in salt, peanut butter & vanilla and mix until combined.
In a seperate bowl, whisk heavy cream until medium stiff peaks form. Fold gently into the peanut butter cream cheese mixture.
