Pre heat the oven to gas mark 5/190C.
Mix all the dry ingredients in a large bowl.
Add the banana, beetroot, almond butter and acai in a food processor until thoroughly blended.
Heat coconut oil gently in a saucepan until melted, then add to the wet mix–pulse for a second.
Add the wet mix to the mixture & stir well until everything is combined (this shouldn’t be too wet).
Line a baking tray with greaseproof paper & spread the mix on top, around an inch thick.
Top with the blueberries and your choice of crunchy toppings.
Bake for 30 minutes–test the middle of the flapjacks with a knife to ensure they are cooked through. If not, bake for a further few minutes and test again.
Remove from the oven, leave to cool slightly & then divide into squares.
