  2. 2 1/2 Cups (530g) white granulated sugar
  3. 1 Cup (95g) unsweetened natural cocoa powder (not Dutch Process)
  4. 1 Tbsp baking soda
  5. 1 1/2 tsp baking powder
  6. 3/4 tsp kosher salt
  7. 3/4 Cup vegetable oil

  9. 2 tsp vanilla extract
  10. 1 1/2 Cups (355ml) full-fat buttermilk*, room temperature DIY recipe in the notes
  11. 1 1/2 Cups hot water


  • Preheat the oven to 350ºF and prepare three 6-inch cake pans by spraying the sides with cooking spray and fitting the bottoms with a wax paper or parchment cake circle. 
  • Place all of the dry ingredients into the bowl of a stand mixer and stir on low for 30 seconds to fully combine them. Add the vegetable oil, eggs, vanilla, and buttermilk and mix on low until just combined. With the mixer still on low, add the hot water in a slow stream, then turn the mixer to medium and beat until smooth, about 2 minutes. The batter will be very thin.
