Preheat the oven to 180C and grease and line a 9x9in baking tin.
First make the cookie dough by blending the ingredients together in a food processor until you have a dough consistency. Tip out and press into the tin making sure to cover evenly.
Melt the coconut oil and dark chocolate then set aside and allow to cool for 5 minutes. Mix together the flour, Natvia and cacao/cocoa powder in a bowl then add the melted chocolate mixture along with the eggs, milk and vanilla. Mix well to combine then fold in the raspberries.
Spread out evenly in the tin then bake for 15-20 minutes until the brownie has firmed up. Leave to cool then cut into 9 pieces. Enjoy!
