This class Australian treat just got a new spin put on it.
Grease a 13x9 inch glass pan with oil and preheat oven to 350 degrees F (180 C). Combine sugar and oil in a large mixing bowl and stir until smooth. Whisk in milk, vinegar, and vanilla. Add baking powder, salt, and pumpkin and mix until smooth, then stir in flour until batter is completely mixed. Pour into prepared pan and bake for 30 to 45 minutes until a toothpick inserted in center comes out clean. Cool completely before assembling cakes. (You can place it in the fridge or freezer once pan is cool to touch if you want this to go faster.)
You can use all the extras; trimmings, filling, coatings, and any ugly ones, to make yummy cake balls! <- Do this!
