Chocolate Almond Swirl Cake

Resist the urge to substitute Greek yogurt here. I tested it, and it made batter too dense. Or! if it's all you have, thin it out a bit, to the consistency of plain yogurt. I haven't tested this, but suspect it will work better than straight Greek yogurt.

Ingredients

  • 3 cups / 13.5 ounces all-purpose flour
  • 2 teaspoon baking powder
  • 1/2 teaspoon fine grain sea salt
  • 1 1/2 cups / 9.75 oz sugar
  • 2 teaspoons almond extract
  • 3 eggs
  • 1 1/2 cups / 12 ounces full-fat plain yogurt
  • 1 1/3 cups / 10.5 ounces extra virgin olive oil
  • 2 tablespoons unsweetened cocoa powder

Chocolate Almond Buttercream Frosting

  • 1 1/4 cup / 285g unsalted butter, room temperature
  • 4 1/3 cup / 525g powdered sugar
  • 3/4 cup / 70g cocoa powder
  • 2 tablespoons milk, cream, or coconut milk
  • 1/2 teaspoon fine grain sea salt
  • 1 tablespoon almond extract

Instructions

  1. Preheat your oven to 325F with a rack in the center. Oil and line a 9-inch square cake pan with parchment paper.
  2. Sift the flour, baking powder, and salt into a medium bowl.
  3. Stir the sugar and almond extract together in a large mixing bowl. Whisk in the eggs, and keep going for a minute or two, until the mixture is light in color and billowy. Stir in most of the yogurt (reserve 2 tablespoons), and then beat in the olive oil until uniform and creamy. Add the flour mixture and fold until barely combined, avoid over-mixing.
  4. Scoop 1 cup of the batter into a separate bowl, add the cocoa powder and the reserved 2 tablespoons of yogurt and stir to combine. Now you have a yellow batter and a chocolate batter.
  5. Place two large spoonfuls of the yellow batter in the middle of the prepared cake pan. Top with one spoonful of the chocolate batter. Alternate this way, 2 spoonfuls yellow batter and one chocolate, directly on top of each other in the center of the pan until all the batter has been used. Very gently rap the pan on the counter to level out the cake.
  6. Bake for 45-55 minutes or until the sides pull away from the pan a bit and the middle has firmed. Cool in the pan for 20 minutes, and then transfer to a cooling rack to cool completely.

Make the Frosting:

  1. Use a mixer to beat the butter on medium speed until creamy. Add the powdered sugar, cocoa powder, milk, salt, and almond extract. Stir by hand with a spoon to incorporate all the powdery ingredients (so you don’t make a mess), and then beat on medium speed for another minute or so. If you want your frosting a bit thicker, add more powdered sugar. If you want it a bit thinner, add more milk a tablespoon at a time. Covered tightly, you can keep the frosting refrigerated for up to a week, longer in the freezer. Bring to room temperature to use.

Frost the Cake:

  1. If your cake is a bit domed, use a serrated knife to level it out. Cut the cake exactly in half. Scoop a generous amount of frosting onto one half and spread evenly. Top with the other half, if you have the patience to do a crumb layer and refrigerate go for it, or simply slather on the frosting and refrigerate. Bring to room temperature to serve.
