Puree the 1¼ cups of strawberries using a blender, food processor, or masher. If using frozen strawberries, you can thaw them a bit in the microwave or use a high speed blender.

In a small pot, add the strawberry puree, sugar, and a third of the cut strawberry pieces. Heat until it comes to a boil. Let it boil for 1 minute, turn off the heat, and let it cool on the counter or chill in the refrigerator.

Take two 16 ounce glasses and add half of the cooled strawberry puree and half of the remaining cut strawberry pieces into each glass. Swirl it up and around the glass to make a pattern. Next pour half of your milk of choice into each glass and serve immediately. Optional: top with whipped cream.
