Preheat your oven to 350°F (175°C).

Grease a 9x13 inch baking pan.

In a large bowl, melt the unsalted butter, then mix it with granulated sugar until smooth.

Add the eggs one at a time, fully incorporating each before adding the next, then mix in the vanilla extract.

In another bowl, combine all-purpose flour, cocoa powder, and salt, then gradually fold this dry mixture into the butter mixture.

Gentle mix in the sliced strawberries into the batter, then pour the mixture into the prepared baking pan.

Bake for about 25-30 minutes, checking for doneness with a toothpick.

Once baked, allow the brownies to cool completely.

Melt chocolate chips mixed with vegetable oil in a microwave or double boiler until smooth.

Drizzle the melted chocolate over the cooled brownies before cutting into squares.
