Notes

  1. Use a neutral-flavored oil like canola or sunflower oil
  2. If you don’t have buttermilk, you can make some by adding 1 tablespoon (15ml) white vinegar or lemon juice to 1 cup (250ml) milk. Leave it aside for 2 minutes which will allow it to curdle. Use in place of the buttermilk.
  3. Give this cake a beautiful decorative touch with any toppings and filling you prefer. Here are a few ideas if you would like to give it a try:
    3 ingredient whipped cream frosting
    Seasonal fruit like blueberries, strawberries, or raspberries
    Chocolate or vanilla buttercream
    A drizzle of fruit syrup
    Sifted powdered sugar
    Plain whipped cream
    A scoop of ice cream
  4. Test if the cake is baked by inserting a skewer into the center of the cake. The skewer should not have any batter clinging to it when removed.
  5. Over mixing will cause a heavy and dense bake. Mix the batter just until all the ingredients have been combined.
