Ingredients

  • 1 cup granulated sugar
  • 2 large eggs, room temperature (see notes below)
  • ½ cup sour cream, room temperature
  • ½ cup whole milk, room temperature
  • ½ cup unsalted butter, melted and cooled
  • ½ teaspoon pure vanilla extract
  • ½ teaspoon butter extract
  • ¼ teaspoon ground nutmeg
  • ¾ teaspoon salt
  • 1 ½ cups all-purpose flour
  • ¼ teaspoon baking soda
  • 1 ¼ teaspoons baking powder

Topping

Instructions

  • Preheat oven to 350°F. Spray an 8-inch square baking pan with nonstick spray and line with a piece of parchment paper, leaving a 1-inch overhang. Set aside.
    NOTE: The nonstick helps the parchment paper hold onto the pan better without it popping up. The parchment paper is going to make this easier to lift the cake out of the pan after baking.
  • Add 1 cup granulated sugar and 2 large eggs, room temperature to a large mixing bowl. Whisk for 1 minute, until foamy.

    NOTE: Oven times CAN vary! Different ovens have different hot and cooler spots. Please go by doneness, not just by time.

  • Allowing the ingredients to come to room temperature helps them incorporate and mix together much easier resulting in a tender cake.
