Melt your butter and honey together over a low heat until you have a syrup consistency.
In a large bowl add your oats, chia seeds, cinnamon and berries.
Pour the melted butter and honey into the bowl with the oats, stir until combined.
Spread the mixture into a lined baking dish and press down with the back of a spoon.
Bake in a preheated oven at 180C for 20-25 minutes, it'll turn a nice golden brown.
Allow to cool, refrigerate for 30 minutes, and enjoy!
