Preheat the oven to 350°F (175°C). Grease and line a baking pan with parchment paper.
In a mixing bowl, combine the melted butter and sugar. Stir in the eggs and vanilla extract.
Sift together the flour, cocoa powder, salt, and baking powder in a separate bowl. Gradually mix the dry ingredients into the wet ingredients until smooth.
Fold in the fresh raspberries, being careful not to break them apart.
Pour the batter into the prepared baking pan and spread evenly. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the brownies to cool in the pan before cutting into squares. Serve and enjoy!
Notes
Feel free to swap out the raspberries for another fruit or add nuts to the batter for extra texture!
