Ingredients:

  • 2 cups (250g) all-purpose flour
  • ¾ cup (150g) granulated sugar
  • 2 tsp (10g) baking powder
  • ½ tsp (3g) salt
  • ½ cup (120ml) neutral vegetable oil
  • ¾ cup (180ml) whole milk
  • 2 large eggs
  • 2 tsp (10ml) pure vanilla extract
  • 1 cup (225g) unsalted butter
  • 3 cups (360g) powdered sugar
  • 2 tbsp (30ml) heavy cream
  • 1 tsp (5ml) pure vanilla extract
  • Pinch of salt
  • ½ cup (60g) multi-colored nonpareil sprinkles

Instructions:

  1. Preheat oven to 350°F (175°C). Grease and line a 9x13 inch baking pan with parchment paper.
  2. In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt.
  3. In a separate bowl, beat the vegetable oil, milk, eggs, and vanilla extract until the mixture is smooth.
  4. Combine the wet and dry ingredients, mixing only until no flour streaks remain.
  5. Pour the batter into the prepared pan and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
  6. Allow the cake to cool completely in the pan.
  7. Use a 3-inch round cookie cutter to press firmly into the cake, rotating slightly for a clean cut, then lift the cake rounds out.
  8. Whip the softened unsalted butter until pale and fluffy.
  9. Gradually beat in the powdered sugar, heavy cream, vanilla extract, and a pinch of salt until smooth.
  10. Frost the tops of the cake rounds with the buttercream and finish by adding multi-colored nonpareil sprinkles.
