Mixed Berry and Ice Cream Whoopie Pies

Heat oven to 375 degrees F. Line 3 large baking sheets with parchment paper. In a medium bowl whisk together the flour, baking powder, salt, and baking soda. Using an electric mixer, beat the butter, sugars, and lemon zest in a large bowl until light and fluffy, about 3 minutes. Reduce the mixer speed to low and beat in the egg. In two additions, alternately add the flour mixture and buttermilk, mixing until just incorporated. Gently fold in the berries. Scoop 32 mounds of batter (about 1 1/2 tablespoons each) onto the prepared baking sheets, spacing them 2 inches apart. Bake in batches until puffed and the tops spring back when lightly pressed, 12 to 14 minutes. Let cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely. Form sandwiches with the cooled pies and ice cream (about 2 tablespoons per sandwich).
