Ingredients

CAKE
  • cups all-purpose flour
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • ¾ cup dark brown sugar
  • 2 ½ tbsp orange zest approx. 5-6 oranges
  • 2 large eggs
  • ½ cup olive oil
  • cup fresh orange juice 1-2 oranges
  • ¼ cup buttermilk
  • 1 tsp vanilla extract
SIMPLE SYRUP
  • 2 tbsp orange juice
  • 2 tbsp sugar
FROSTING
  • 3 oz. cream cheese room temperature
  • 6 tbsp salted butter room temperature
  • ½ tsp vanilla extract
  • ½ tbsp milk
  • 2 ½ cups powdered sugar
SALTED CARAMEL
  • ½ cup sugar
  • cup heavy cream room temperature
  • 2 tbsp butter small cubes (slightly softened)
  • ¼ tsp sea salt

Instructions

CARAMEL

  • Pour your sugar into an even layer along the bottom of a medium-sized pot and place it over medium-low heat on the stove
  • Stir every 20-30 seconds with a spoon - it will look like nothing is happening at first. As the sugar slowly melts, it will get a little clumped, and you’ll notice the color slowly change. Once the sugar is completely melted, immediately remove it from the heat
  • Add your butter to your pot and whisk in
  • Carefully stream your room temperature heavy cream into your pot and stir before mixing in your sea salt
  • Set aside to cool at room temperature before assembly - can be lightly warm, but no hotter, or it will melt the frosting

CAKE

  • Preheat oven to 350°F and grease and line a 9-inch round pan with parchment paper
  • In a mixing bowl, whisk together your flour, baking powder, baking soda, and salt, and set aside
  • In a separate large bowl, add your dark brown sugar and orange zest. Rub the zest into the sugar with your fingers to release the oils, until fragrant (about a minute)
  • Crack in your eggs and whisk for 1 minute until the mixture pales in color. Pour in your olive oil, orange juice, buttermilk, and vanilla, and whisk until smooth
  • Sift in your dry ingredients, mixing until just combined
  • Pour your cake batter into your greased and lined pan
  • Bake for 25 minutes, or until a toothpick inserted comes out clean with a few moist crumbs
  • While your cake is baking, prep your simple syrup. In a small pot, combine your orange juice and sugar. Whisk over medium heat until the sugar dissolves, then reduce the heat and simmer for 2 minutes, or until lightly reduced. You’re not looking for thick syrup, but just lightly thickened to evaporate some water. Remove the pot from the heat, pour into a bowl, and allow the mixture to cool slightly
  • Remove your cake from the oven and allow it to cool in the pan for 10 minutes. Invert onto a wire rack, and while still warm, use a pastry brush to brush all of the syrup on the cake (top and sides!)
  • Cool completely before assembling

FROSTING

  • Add your room temperature cream cheese and butter to a mixing bowl and beat for a minute until smooth
  • Sift in your powdered sugar and carefully beat until all incorporated
  • Mix in the vanilla and milk

ASSEMBLY

  • Place all of your cream cheese frosting on top of the cooled olive oil cake and smooth out
  • Drizzle over some of your caramel and then swirl it in with a spoon or spatula. Save the rest for drizzling over individual slices
  • Top with fresh orange segments and, if desired, dehydrated oranges

Notes

*If you don’t have dark brown sugar, substitute it with light brown sugar and add 2 tablespoons of sour cream with your remaining wet ingredients
*For the caramel, the butter and heavy cream shouldn’t be cold. This could cause your sugar to seize when you stir it in!
*If you want to make dehydrated orange slices, I’d highly recommend making these at least a day in advance since they take a while. Preheat your oven to 200°F and line a baking sheet with parchment paper. Slice one orange into ⅛” - ¼” slices and lay flat on your baking sheet. Bake for 3-4 hours until dry and no longer sticky to the touch
*I adapted this salted caramel recipe from one I received from Chef Ash during my pastry course
