Prepare two 8x13inch baking trays with parchment paper
Place flour, oats, coconut, cranberries, sunflower seeds in a large bowl
Melt the butter and honey together in a saucepan until just melted
Combine baking soda and warm water to dissolve and add to butter/honey mixture
Immediately add the butter mixture to the flour mixture (as baking soda starts to work as soon as it mixes with the honey) and mix well until well combined
Place tablespoon sized balls of cookie dough onto the tray and flatten as much as you can without breaking the cookie
Bake for 12-15 minutes until golden
Remove from oven and let the cookies cook in the tray for around 10 minutes before moving them onto wire racks to cool completely
