Perfect for the summer season, this mixed berry pie is our take on a slab pie, all baked to perfection in your Challenger Bread Pan. Thanks to the generous sizing of the Pan, this pie big enough to share with family and friends, and the filling can easily be adapted to use whatever berries are in season where you live. You can also use frozen berries with delicious results! Get creative with the pastry decoration: make a braided lattice for a classic look, or go for a festive spark with cut out stars.
