Step 1

Preheat the oven to 350°F. Grease and line a 8 x 8-inch pan with parchment paper on all sides and set aside.

Step 2

Place the melted butter, cocoa powder, and vanilla in a mixing bowl and whisk to combine until no lumps of cocoa remain. Set aside.

Step 3

In a stand mixer fit with the whisk attachment, beat the eggs and brown sugar together until light, fluffy and pale in color.

Step 4

Add the butter mixture to the egg mixture and use a rubber spatula to fold together.

Step 5

Add the flour and the salt and fold the mixture until no streaks of flour remain. Last, gently fold in the raspberries and chocolate chips (if using)

Step 6

Transfer mixture into prepared baking pan and bake for roughly 25 minutes, testing for doneness by inserting a knife into the center of the brownies beginning at 20 minutes. You’ll know they’re done when the edge is set, but a knife inserted into the middle still comes out with a bit of brownie batter on it. It might take up to 35 minutes for them to cook through depending on your oven!
