Bake in the preheated oven for 35-40 mins. A skewer or knife, when inserted 2 inches from the side, should come out clean. If inserted in the centre it will be a bit sticky which is alright. Do not overbake.

Remove from the oven and let it cool in the tin for 20-30 mins. Lift with the sides of the paper to remove the brownie from the tin and place it on the counter. Cut into 9 or 12 equal pieces. Serve warm with ice cream.
