Preheat oven to 350F. Line a 9×9 pan with parchment paper and grease it with vegetable oil. Place the tomatoes in a blender or food processor and purée until smooth. Measure out 2 cups. (use the rest for tomato sauce!) Beat eggs, sugar and molasses until smooth. Add oil, mix and then add flour, baking soda, salt and spices. Mix well. Add tomatoes and mix it all together until smooth. Pour into pan and bake for 65-75 minutes or until firm to the touch. Let it cool completely on a wire rack. For the glaze, place the sugar and cinnamon in a bowl and slowly stir in the milk and vanilla, a little at a time, to make a smooth, pourable glaze.
