Preheat oven to 350 F
Combine all wet ingredients together in a bowl and whisk. Then stir in the shredded zucchini.
Mix together all dry ingredients, except the chocolate.
Roughly chop the chocolate into craggy pieces.
Pour the dry ingredients into the wet and mix until batter forms. Fold in the majory of the chocolate, reserving a small handful.
Pour batter into a loaf in tined with parchment paper.
Toss the reserved chocolate in a little bit of spelt flour, to help them float on top of the bread and not sink. Scatter over top the batter.
Bake for 35-45 minutes until a toothpick inserted in the middle comes out clean.
