Preheat your oven to 190C (375F). Line a large cookie sheet with parchment paper.
In a mixing bowl, cream the butter, sugar and honey together. I have just done this with a fork for this recipe (because I want these to be a quick easy recipe), however if you'd prefer to do it with an electric hand mixer or stand mixer you can.
Now add the sourdough starter and whisk well to combine with the butter, sugar and honey.
Now add the egg and vanilla and beat to combine. Again, I'm just using a fork to bring this recipe together.
On top of the wet mixture, add all of the dry ingredients - all purpose flour, baking soda, baking powder, salt, rolled oats, desiccated coconut, chia seeds, flax seeds, dried fruit and chopped nuts.
Mix together using a spatula until it's just combined - try not to over mix it. You just want the wet ingredients to moisten the dry ingredients.
Using your hands, form the mixture into 8 large balls of cookie dough. Place the balls onto the lined cookie sheet you prepared earlier. Gently press them down with the back of a spoon.I've made them 100g each but you can really make them any size you like. The smaller you make them, the more cookies you'll get but I like the jumbo sized for a grab and go breakfast. Bake in the oven at 190C (375F) for around 30 minutes (if you are making smaller cookies you'll need to reduce the cooking time).
Remove from the oven when the cookies are just golden brown. They will still be soft but they will crisp up as they cool. Allow to cool on the cookie tray for 10 minutes before transferring to a wire rack to cool fully.
