First you can preheat the oven to 180°C (fan oven).
First drain the beans and then put them in a bowl.
Then puree the beans thoroughly with a blender until a creamy mixture is formed.
Then add the cocoa powder and mix the bean mixture well with it.
Then add the oats, chia seeds, grated nuts, maple syrup and melted coconut oil and mix well until a dough is formed. Then pour the batter into a baking dish and smooth it out.
Depending on how high the mixture is in your tin, the brownies will take 20-30 minutes in the oven. Before you can enjoy the brownies, it is best to let them cool a little before you take them out of the tin and cut them into pieces.
