Preheat the oven 350 F and line a 9x9 inch square tray with parchment paper or foil and spray with non-stick spray.
Combine the butter and sugar together and microwave together for 30 second intervals until the butter melts completely up to one minute.
Add in the eggs, baking powder, salt and vanilla or coffee extract.
Next, mix in the cocoa powder and flour until incorporated and no lumps.
Finally, fold in the chopped up chocolate.
Pour the mixture into the prepared pan, add chopped strawberries by dropping them onto the brownie batter, then bake for 20-25 minutes or until a toothpick inserted comes out with a few moist crumbs.
Cool slightly before serving or serve cold.
