Preheat your oven to 180°C. Line a baking tray with parchment paper. This prevents cookies from sticking. Set everything ready before starting the mixing process.

In a bowl, add flour, baking soda and salt. Mix well using a spoon. This helps spread the baking soda evenly. Keep this mixture aside for later use.

In another bowl, add softened butter, brown sugar and white sugar. Beat until smooth and fluffy. This step gives cookies a soft and chewy texture.

Add eggs one at a time into the butter mixture. Mix well after each egg. Add vanilla extract and mix again until everything looks smooth and creamy.

Slowly add dry ingredients into the wet mixture. Mix gently. Add oats, chocolate chips, walnuts and coconut. Stir until everything combines into a thick cookie dough.

Scoop dough onto the baking tray. Leave space between cookies. Bake for 10–12 minutes until golden brown. Let them cool for a few minutes before serving.
