For topping:
Preheat oven to 375 degrees F. Spray a 9-inch round cake pan with cooking spray and flour lightly.
In a large bowl, sift the flour, baking soda and salt together. Set aside. In a small bowl, mix chia seeds with water and set aside to gel.
Slowly melt unsweetened dark chocolate. Allow it to cool slightly but don't let it harden.
In a large bowl, beat butter with yams, brown sugar, applesauce and honey for 2 minutes. Add chia gel and beat for another 2 minutes. Beat in vanilla and then chocolate. Gradually stir in half the flour mixture and then half the yogurt. Repeat with the remaining flour mixture and yogurt. Slowly and carefully stir in the boiling water. Pour the batter into the prepared cake pan.
Bake for about 20 minutes. Test cake with a toothpick. It should be wet but not gooey.
Cool in pan on a rack for 20 minutes.
Remove cake from pan and cut into 12 pieces.
Drizzle melted chocolate over cake. Place on plates and garnish with strawberries and cinnamon, if using.
