Ingredients

3/4 cup fresh or frozen blueberries1/4 cup sugar1 tablespoon vanilla extract2 cups heavy whipping cream1 cup sweetened condensed milk4 whole graham crackers, coarsely crushed

Preparation

In a small saucepan, combine blueberries, sugar and vanilla. Bring to a boil; reduce heat. Simmer until mixture begins to thicken, about 5 minutes, stirring frequently. Cool completely. Refrigerate until chilled.

In a large bowl, beat cream until soft peaks form. Add condensed milk; beat until mixture thickens. Gently fold graham crackers into cream mixture. Transfer to freezer containers, allowing headspace for expansion. Drop blueberry mixture by tablespoonfuls over ice cream. Cut through ice cream with a knife to swirl. Freeze for 8 hours or overnight before serving.
