  • 2 refrigerated store bought pie crusts I used Trader Joe's total weight 22 oz (11 oz per pie crust)
  • 3 1/2 cups fresh raspberries and blueberries reserve 1/2 cup for garnish
  • 1 lemon
  • 1/2 cup white sugar
  • 2 tbps cornstarch
  • 1 egg beatened with 1 tbsp water
  • 1/2 - 2/3 cups powdered sugar
  • 2-4 tsp milk
  • 8 oz cream cheese softened, room temp


  • Preheat oven to 425 degrees
  • Line a 9"x13" baking pan with parchment paper
  • In a bowl, mix 3 cups berries with sugar, cornstarch, juice and zest of one lemon, let that sit for the juices to come out about 15 minutes.
  • Roll out your 2 pie crust to an approximate 9" x 12" rectangle, make one slightly bigger. If it gets too soft chill in refrigerator.
  • Lay your slightly larger slab of your rolled out pie crust over the parchment lined pan, add your berry mixtures with a slotted spoon, we don't want soggy pie.
  • Lay your other pie crust over the the berries, pinch the edges all around. Cut a few slits over the top to vent.
  • Mix egg with a tablespoon of water, brush all over the pie. 
  • Bake for 30-35 minutes until bubbly and golden. Allow to cool completely before slicing.
  • If making cream cheese drizzle, mix cream cheese, powdered sugar and milk until drizzling consistency. If too soft, add a bit more powdered sugar, if too stiff, add more milk. Add to a sandwich zipper bag, snip off end and drizzle. Add berries to garnish on top.
