In a blender, combine ice cream, milk, strawberry pieces, and banana pieces, and blend until well-combined and pourable.
Pour into a glass. Top with whipped cream if desired and enjoy.
Notes
*Using frozen fruit will give you a thicker, frostier shake but can be a little hard on some blenders. If using frozen strawberry and banana pieces, allow your ice cream to sit at room temperature for 5 to 10 minutes before blending, until it just begins to melt. Otherwise, you might have trouble getting everything to blend.*Use 1/2 cup milk for a thicker shake, up to 3/4 cup for a thinner one.Approximate nutritional information is for 2 servings without optional whipped cream.
