For Cake:

  • 1 cup (198 grams) granulated sugar
  • zest of 2 lemons
  • 3 large eggs
  • 1/2 teaspoon vanilla
  • 1/2 cup (113 grams) buttermilk
  • 3 tablespoons lemon juice
  • 1 tablespoon poppy seeds
  • 1 stick (113 grams) unsalted butter melted and cooled
  • 1 3/4 cup (210 grams) all-purpose flour
  • 1 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt

For Icing:

  • 1/2 block (113 grams) cream cheese
  • 1/2 cup (99 grams) granulated sugar
  • 1/2 teaspoon vanilla
  • pinch of salt
  • 3/4 cup (170 grams) heavy cream


For Cake:

  • Preheat the oven to 350 degrees (F). Spray a 9-inch square cake pan with non-stick spray and lay 2 strips of parchment paper in a cross shape across the bottom. Set aside.
  • In a large bowl combine the granulated sugar and the lemon zest. Whisk well to help release the oils in the zest.
  • Whisk in the eggs, vanilla, buttermilk, lemon juice, and melted butter until combined.
  • In a separate bowl combine the flour, baking soda, baking powder, poppy seeds, and salt.
  • Fold the dry ingredients into the wet ingredients until just combined.
  • Pour the batter into the prepared pan and bake for 35-40 minutes or until an inserted toothpick comes out clean.
  • Remove from oven and allow to cool.

For Icing:

  • In a medium bowl combine the room temperature cream cheese, sugar, vanilla, and salt. Mix until fully combined.
  • In a separate medium bowl whip the cream until stiff peaks form. Be sure not to over whip.
  • Add about 1/4 of the whipped cream into the cream cheese and mix until completely combined. Add the rest of the whipped cream and gently fold into the cream cheese mixture.
