In a small saucepan over medium heat, combine the water and granulated sugar, stirring gently until the sugar fully dissolves—about 3 to 4 minutes.

Meanwhile, mash the chopped strawberries in a small bowl. Once the sugar has dissolved, add the mashed strawberries to the saucepan and reduce the heat to low. Let the mixture simmer for about 7 minutes, stirring occasionally, until it thickens slightly and becomes syrupy.

Remove the saucepan from the heat and allow the strawberry syrup to cool completely.

In a medium mixing bowl, whisk together the powdered sugar and vanilla extract. Once the strawberry sauce has cooled, pour it into the bowl and stir until the glaze is smooth and fully combined.
