Add blueberries, cherries, ice cream, milk, and vanilla extract to a blender. Tip: For a thicker shake, freeze the berries for 30 minutes first.

Blend on high speed until smooth and creamy, about 1-2 minutes. Tip: Stop and scrape down the sides if needed.

Taste and add honey or maple syrup if you prefer extra sweetness. Tip: Adjust milk for thinner consistency.

Pour into chilled glasses and serve immediately with a spoon. Tip: Garnish with extra berries or whipped cream.
