Preheat oven to 175 degrees.

Grease and line a 9 x 22cm loaf tin with parchment paper.

Melt butter in small saucepan, once melted keep on very low heat and whisk in the sugar until smooth.

Turn heat off, add dates and stir through. I highly recommend dipping the finger in to make sure it tastes ok.

Transfer to a large bowl and stir in egg and vanilla.

Add flour, oats, chia and sunflower seeds and stir until combined.

If mixture appears too wet, add in more oats and flour and stir through

Pour into loaf tin and bake for 20 minutes.

Cool in pan for 5 minutes, turn out onto a wire rack.

Once cool, slice into bars and pop into lunchboxes.

Can be frozen.
