This rich buttery tender cake can be made into a layer cake and then smoothened with a creamy chocolate buttercream. It is so good. To start, preheat your oven to 350F/ 180C then grease or line an 8-inch round or rectangle baking pan. Into a mixing bowl, sift in two and a third cup of all-purpose flour, a quatre cup of cornstarch, half a teaspoon of baking soda, one teaspoon of baking powder and half a teaspoon of salt.

Give that a good mix with a whisk until it’s all combined and set it aside. In another large bowl add half a cup of room-temperature unsalted butter, half a cup of oil and one and two-thirds cups of white granulated sugar. Using a hand or stand mixer on medium speed, cream that together for two minutes until it’s light and fluffy. Next, you want to add two large eggs at room temperature one at a time while mixing on a low speed and you want to mix well in between each addition.

You will then add three additional egg yolks and you want to mix that on a low speed until well combined. The egg yolks are going to make the cake richer and add colour to the batter as well. and give the cake the signature yellow colour. Once that is well mixed, add one and a quarter teaspoons of vanilla extract, and one teaspoon of white vinegar that is going to help achieve a more soft and tender crumb and finish off by adding one and a quarter cups of room temperature buttermilk.

Mix that on a low to medium speed until well combined. To finish off the batter, add the pre-sifted dry ingredients from earlier and fold that in with a spatula until just combined. You don’t want to overmix the batter so just mix until you can’t see any more streaks of unmixed flour running through the batter. Pour the batter into the prepared cake pans then level the tops and drop the pans slightly on the counter to remove any large air bubbles bake in the preheated oven for 38 to 40 minutes. once baked, remove from the oven and let the cakes cool on a wire rack.

At this point, you can serve the cakes plain with a cup of tea or you can go further and let them completely cool then layer them with chocolate frosting. Whichever way you choose to serve this cake, it will surely be a hit on your table.
