1) Preheat the oven to 350 degrees Fahrenheit (between gas mark 4 and 5). Oil and flour a tube pan or cup cake tin.
2) Beat tofu (or mix corn starch and water well). Add sugar and oil and beat for 3 minutes. When using corn starch, I do this using a whisk, but when using tofu, it's best to do this in a food processor. Sift remaining dry ingredients together and add slowly to the creamed mixture. Add apples and vanilla. Stir until well mixed. It will be a thick mixture.
3) Bake for 1 hour and 15 minutes or until a toothpick inserted in the center comes out clean. Leave in the pan until almost cool.
Variation: Use 3 cups of apples and 1 of chopped nuts like walnuts, pecans, etc.
