Moist Chocolate Spinach Tray Bake recipe -Healthy German Lebkuchen alternative

all 4

This recipe might sound a bit odd but trust me, you can not taste the spinach at all. The rich flavour of chocolate and the fragrance of spices makes you forget that you are actually eating vegetables.

You will need a food processor though as all raw ingredients are mixed and chopped together.
However, this is a very quick and healthy alternative to German Lebkuchen which is originally made with flour, honey and nuts.
Please plan ahead and defrost your spinach completely overnight or a couple of hours before baking.

If you wish you can replace the cranberries with other types of berries or leave them out completely. Another alternative is to add 1/2 cup of chopped nuts.
