Walnut and Chocolate Brownies

Preheat the oven to 180°C (160°C fan) and line an 8-inch square baking tin.
Soak the dates in hot water for 5 minutes, then drain.
Stir in the cocoa powder, oat flour, baking powder and salt.
If using protein powder, mix it in now. Add an extra splash of milk if the batter becomes too thick.
Fold in the chocolate chips and most of the walnuts.
Pour into the prepared tin and scatter the remaining walnuts over the top.
Bake for 22-25 minutes until just set in the centre.
Allow to cool completely before slicing and enjoy!
