Preheat your oven at 170 C/330 F/Gas Mark 3
Put the butter and chocolate together in a medium saucepan and melt them gently over heat whilst stirring.
Add in the sugar and stir until all dissolved. Tip in the 3 beaten eggs.
Stir until shiny and all mixed through.
Finally add the flour.
Stir again till shiny as a shiny thing and tip into your baking tray. I line mine in baking paper for ease of pulling the brownies out after baking.
Push in your raspberries with clean fingers into the brownie batter so that they are almost submerged completely
Bake for about 35/45 minutes at 170 C/330 F/Gas Mark 3 depending on tin used. I like my brownies fudgy in the middle so they tend to be ready at 35 minutes but all ovens vary.
Usually when the crackly top starts to rise is when they are approaching being done.
Now fudgy brownies are a little fussy about how they are treated straight after baking. They want to be left all alone until cool, maybe even into the fridge for a while for all that fudge to go about steadying itself for even greater fudginess.
I let the Brownies cool in the tin but I do run a knife around the edge to make sure it hasn't stuck. When cool use a sharp knife to cut into sections.
