Now this recipe may sound a bit naff, but my husband baked them as the ingredients are known for their anxiety-beating and mood-regulating properties…. and you know what? They’re actually really tasty!! If you like carrot cake you’ll like these 
90g whole-wheat flour
30g milk powder
1.5 teaspoons baking powder
quarter teaspoon nutmeg
half teaspoon cinnamon
60g oats
120g unsalted butter (softened)
60g brown sugar
1 egg
200g mashed sweet potato
3 tablespoons molasses
half teaspoon vanilla essence
Cook (boil) and mash the sweet potato to start with and put to one side, then preheat the oven to 170C/gas 3 and grease a small cake pan (square is best for cutting into ‘bars’ later, but round is fine).
In a bowl sift the flour, milk powder, baking powder and spices into a bowl, add the oats and put to one side.
In a mixing bowl mix together the butter and sugar until fluffy – beat in the egg, sweet potato, vanilla and molasses, the gradually beat in the dry ingredients.
Pour the mixture into the cake pan and bake for 25 minutes until firm to touch and when an inserted toothpick comes out clean.
Allow to cool then cut into bars…
Eat, and relax….
