Preheat your oven to 350°F (175°C) and prepare the baking pan.
In a large mixing bowl, melt the butter and mix with sugar.
Add in the eggs one at a time, followed by the vanilla.
Sift together the cocoa powder, flour, and salt, then fold gently into the wet mixture.
Gently fold in the chopped strawberries.
Pour the batter into the prepared baking pan and smooth the top.
Bake for 25-30 minutes, or until a toothpick comes out with a few moist crumbs.
Allow the brownies to cool in the pan for 10 minutes before transferring to a wire rack.
Cut into squares and enjoy your delicious strawberry brownies!
