Line a baking/cookie sheet with baking paper.
In the bowl of a mixer or electric hand mixer beat the butter, sugar and egg until combined.
Add the flour, bicarb soda. Mix on a low speed to avoid a flour mess. Once incorporated, mix on a higher speed till combined.
Add in the oats, dates, almonds and chia seeds.
Mix on a low speed till they're dispersed through the mixture.
Store in the fridge for 30 minutes.
While in the fridge, pre-heat your oven to 180c.
Roll into 1 inch sized balls and place evenly on the tray.
Bake for 10-12 minutes.
The cookies are done when they start to turn golden and are still slightly soft in the middle.
