Instructions
Pumpkin Cake
Preheat oven to 180 °C (350°F) conventional (see note 3 if using a convection oven with a fan) and lightly grease a 9x13 inch cake pan (I use my homemade cake release). Line the bottom long ways with parchment paper as well (this will make it easier to take the cake out when it's done).
In a bowl, sift together flour, cornstarch, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, allspice and cloves. Using a whisk, mix until well combined. Set aside.
In a large bowl combine white sugar, light brown sugar, eggs, vegetable oil, pumpkin puree, milk and vanilla. Using a clean whisk, mix until well combined and smooth.
Pour your dry ingredients into your wet ingredients and using a spatula, gently fold until just combined. Do not overmix the batter (see note 4).
Pour the batter into the prepared pan, and bake for 28 minutes or until a toothpick inserted into the centre comes out clean or with a few moist crumbs on it.
Allow the cake to cool in the cake tin for about 20 minutes and then turn it out onto a wire rack to completely cool, before frosting with the cinnamon cream cheese frosting (recipe below) and garnishing with roughly chopped pecans or walnuts.
Cinnamon Cream Cheese Frosting
Cream butter for a few minutes until light and fluffy. Either use a hand mixer or stand mixer on a medium high speed. If using a stand mixer, use the paddle attachment.
Add in the powdered sugar in 3 batches while mixing on low. Ensure that each batch of powdered sugar is mixed into the butter well before adding in the next batch.
Next add in the cold cream cheese, vanilla and cinnamon. Mix just until the frosting is smooth. Avoid over-mixing (see note 5).

Notes
Note 1. If using measuring cups for this recipe, then you want to firmly pack your soft brown sugar. To do this, pack your measuring cup with sugar and using the back of a spoon, press the sugar into the cup with a little bit of pressure (not too much) and then fill the remaining cup with more sugar.Note 2.If using canned pumpkin, ensure that it's 100% pumpkin (do not use pumpkin pie filling). Although I would recommend using canned pumpkin, fresh pumpkin will work too. You just want to make sure there isn't too much liquid in your homemade pumpkin puree. Here is a great article for how to make homemade pumpkin puree: https://www.bbcgoodfood.com/recipes/pumpkin-pureeNote 3.If using a convection oven that has a fan function, bake at 160 °C (320°F) as the fan function bakes food faster.Note 4. By gently folding in the ingredients, it prevents too much gluten from forming, thus giving us a softer cake. Only mix until the strands of flour have disappeared and the batter is uniformNote 5. Only mix the frosting until it's smooth. Once it's smooth stop mixing as over-mixing can result in a less stable frosting. This is because of the liquid in the cream cheese breaking down the powdered sugar. Note 6. If you have pumpkin pie spice, you can use that in replacement of the spices in this recipe.
