Preheat the oven to 350°F(175°C).
Lightly grease three 8-inch(20 cm) round cake pans with oil and line the bottoms with baking paper.
In a large mixing bowl, whisk together the milk and lemon juice and let it sit for 10 minutes until slightly curdled.
Add the oil, vanilla extract, light brown sugar and cane sugar then mix until the sugar is fully dissolved.
Sift in the flour, baking powder, baking soda, cinnamon powder, and salt. Stir until the batter is smooth and free of lumps.
Mix Molasses syrup if using.
Pour the batter evenly into the prepared pans. Bake for 25 to 30 minutes, or until the tops are set and spring back when gently pressed.
Allow the cake layers to cool completely on a wire rack.
