First, preheat the oven to 350ºF.
Coat a 9x13 inch baking pan, or a round cake pan, with tahini paste. Use your hands, a brush, or a cooking spray.
Lightly dust the sides of the pan with about 1 teaspoon of all-purpose flour.
In a large bowl, mix together the dry ingredients consisting of all-purpose flour, sugar, turmeric, baking powder, and salt.
Add you vegetable or avocado oil and milk to the dry ingredients, and mix for about 2-3 minutes with an electric mixer.
Pour the batter into the prepared pan, and sprinkle pine nuts on top of batter.
Bake on 350ºF for 28-30 minutes or until a toothpick inserted in the center of the cake comes out dry.
Allow the cake to cool for at least 10-15 minutes before cutting.
