1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.

Step 2: Make the Brownie Batter

1. In a medium saucepan, melt the butter over low heat. Remove from heat and stir in the granulated sugar until well combined.
2. Let the mixture cool slightly, then stir in the eggs and vanilla extract until smooth.
3. In a separate bowl, whisk together the cocoa powder, flour, salt, and baking powder.
4. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Do not overmix.

Step 3: Add Raspberries

1. Gently fold in the fresh raspberries, being careful not to break them apart too much.

Step 4: Bake the Brownies

1. Pour the brownie batter into the prepared baking pan, spreading it evenly.
2. Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
3. Remove from the oven and let the brownies cool in the pan on a wire rack.

Step 5: Serve

1. Once cooled, cut into squares and serve. Optionally, dust with powdered sugar or serve with whipped cream for added sweetness.
