Preheat your oven to 180°C/350°F and line a 9x5 loaf pan with parchment paper, leaving some overhang for easy release.
In a small bowl, whisk together the flour, baking soda and baking powder.
In a medium bowl, whisk together the oil, sugars, cornstarch, tahini, milk, vanilla, salt and cinnamon.
Add the flour mixture and stir until a smooth dough forms, then stir in the oats.
Transfer the dough to your lined loaf pan and even it out with your spatula or hands. Sprinkle the chocolate and almonds on top and lightly press them in, then sprinkle with the flaky salt.
Bake for 25-30 minutes then let cool a few minutes in the pan before pulling it out using the parchment paper overhang and placing on a wire rack to cool completely.
It’s easier to cut if it has completely cooled, refrigerated is even better if you want clean cuts.
