Cover the entire inside of the pans (the bottom and the sides). Cut parchment paper into circles and place in the bottom of the pans. Set aside. Add to large glass measuring cup and set aside: 240 g (1 cup) buttermilk or: 212 g (1 cup minus 1 tbsp) milk 14 g (1 tbsp) white vinegar or lemon juice Stir with a fork or spoon to combine (about 15 seconds). Set aside for 5-10 minutes. Sift into large mixing bowl: 360 g (3 cups) cake flour 8 g (2 tsp) baking powder 1/2 tsp baking soda 5 g (1 1/2 tsp) kosher salt Whisk until combined (less than 30 seconds). Set aside. If there's anything in the oven, take it out. Set the oven to bake, 350° F (177° C). Attach the paddle to the mixer. Add to mixer mixing bowl: 226 g (1 cup) butter (chopped into about 8 pieces) 57 g (1/4 cup) vegetable oil Mix on low-then-high speed until smooth (about 30 seconds). Add to mixer mixing bowl: 350 g (1 3/4 cups) sugar Mix on low-then-high speed until light and fluffy (about 5 minutes). When ready, it should be pale yellow in colour, and it should have increased in volume. Add to small mixing bowl: 5 egg yolks (80 g) 2 eggs (100 g) Set mixer to low speed. Add each yolk one at a time. After adding a yolk, briefly increase to medium speed, then set back to low speed before adding the next yolk. Set mixer to low speed. Add to buttermilk: 1 tbsp vanilla extract Add to mixer mixing bowl: about 1/3 of dry ingredients mix on low until most of the flour disappears about 1/2 of buttermilk pulse the mixer a few times (turn off/on in short bursts) about 1/2 of remaining dry ingredients mix on low all remaining buttermilk mix on low all remaining dry ingredients Pulse until smooth. Scrape the sides. Mix on high for about 5 seconds. Turn off the mixer. Remove the bowl from the mixer. Pour the batter into the pans (about 723 g per pan). If necessary, use a spatula to spread the batter evenly/flatly. Tap the bottom of each pan firmly against the table to remove air bubbles. Place both pans in the oven on the middle rack. Ensure there is space all around each pan for better airflow. Place one pan closer to the back wall and the other pan closer to the front window. Set a timer for 30-35 minutes. To test for doneness, stick a toothpick in the centre of the cake. If the toothpick comes out clean (or with just a few dry crumbs), the cake is ready. If you touch the top of the cake, it should bounce back. If it sinks, it's not ready. The cake should be slightly pulling away from the edges of the pan. The top and edges of the cake should be slightly browned. When the timer is done, remove the pans from the oven. Turn off the oven. Let cool in the pans for 10 minutes. Invert each cake onto a wire rack: Gently run a butter knife or offset spatula along the inside edges of the pan to loosen the cake from the side of the pan. If the pan is still hot, put on oven mitts. Place a wire rack upside down on top of the cake. Place one hand on top of wire rack on top of the cake. Pick up the pan with your other hand. Swiftly flip the cake and wire rack together upside down, placing the wire rack right side up on the table. Lift the pan. If the cake doesn't fall out, tap the bottom of the pan to loosen the cake. Remove the parchment paper from the cake. Flip the cake upside down again so the flat side is on the bottom. Let cool completely on the wire racks (at least 25-35 minutes). Once the cakes have cooled completely, using a serrated knife, cut off the tops of the cakes to make it flat. If the cake is not going to be decorated today, wrap the cakes in plastic wrap separately and place them in the fridge. To decorate the cake, prepare buttercream icing or Swiss buttercream icing.
