Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan and set aside.
In a large mixing bowl, whisk together the flour and sugar until well combined, creating a light, uniform mixture.
Add the melted butter, eggs, milk, and vanilla extract to the dry ingredients. Beat with a whisk or electric mixer until the batter is smooth and slightly thickened, about 2 minutes.
Gently fold in the chopped strawberries until evenly incorporated, noticing the batter becoming speckled with vibrant red pieces.
Pour the batter into the prepared baking pan, spreading it evenly with a spatula. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Remove the cake from the oven and let it cool in the pan for about 15 minutes. Once cooled, transfer to a wire rack if desired, and decorate with a light glaze or whipped cream before serving.
