This fabulously frozen berry pie has seen many variations in our house. It or something similar are always welcome when the temperature & humidity of a Minnesota summer keep me from wanting to make any type of dessert that requires the oven to be on for an hour or more.
This recipe was developed as I was staring at many quarts of frozen strawberries from an amazing U-Pick place near my family’s cabin near Ottertail Lake and at some point I decided I could & should use them for more than my soy strawberry banana smoothies! I remembered having a similar pie at graduation parties & summer BBQs over the years that was a little too pre-packaged/processed for my taste: pre-made graham cracker crust with an artificially flavored yogurt/cool whip filling. So I became interested in finding something similarly refreshing, yet less processed.
This more homemade version uses a nice combination of fresh strawberries & blueberries that nicely enhances the creamy, sugary base. The crust can be made of other types of crackers or cookies you prefer – we’ve used graham crackers & chocolate wafers in other variations. I think the vanilla wafer & nut combo is my favorite though. Pecans are a great substitute for the walnuts. Any combination of berries would be delicious, I like adding raspberries when they are in season. And as an added bonus, it is perfect to make a day or 2 ahead of when you need it… just remember to take it out of the freezer a little while to thaw slightly before serving.
This dessert is the perfect ending to a backyard BBQ and could be easily be made into individual portions in ramekins or a cupcake pan for a more sophisticated garden party. To dress the pie or individual dessert up a little, finish with some fresh whipped topping, pretty berries & a sprig of mint. Enjoy!
- 1½ cups vanilla wafers crumbs
- ½ cup chopped walnuts
- 5 tablespoons melted butter
- 2 teaspoons vanilla
- 1½ cups sliced strawberries
- ½ cup blueberries
- ¾ cup sugar
- 1 egg white
- 1 cup sour cream
For the filling, combine strawberries, blueberries, sugar & egg white in a mixing bowl. Beat at high speed until it forms soft peaks (could take up to 10 minutes). Gently incorporate the sour cream by hand. Pour the filling into the crust & place the pie in the freezer. Be sure to take it out a little while before serving so it’s not impossible to cut, it will freeze fairly solid. A dollop of whipped cream is always a good way to finish.
Note: If you use frozen berries, you can decrease the sugar to about ½ cup.
