This wonderfully soft and fluffy orange cake comes together in a blender with barely any effort, then gets soaked in a warm orange syrup the moment it comes out of the oven. Simple, fragrant, and impossible to resist — it stays incredibly moist for days.

🛒 Ingredients

10 servings

10
  • 2 ripe navel oranges, peeled, pith removed, and seeds discarded
  • 1½ cups (300 g) granulated sugar
  • ½ cup (120 ml) neutral oil (sunflower or vegetable)
  • 2 heaping cups (260 g) all-purpose flour
  • 3 large eggs
  • 1 tablespoon (11 g) baking powder
  • Syrup: juice of 2 oranges, strained
  • 2 tablespoons sugar (for syrup)
  • 1 teaspoon margarine (for syrup)

Directions

  1. 1

    Preheat oven to 425 °F (220 °C). Grease and flour a bundt or tube pan thoroughly.

  2. 2

    Cut the peeled oranges into chunks and add to a blender with the oil and eggs. Blend for 2 minutes until completely smooth.

  3. 3

    Add the sugar and blend on high speed for another 2 minutes.

  4. 4

    With the blender running on low, slowly pour in the flour until the batter is smooth and well combined.

  5. 5

    Turn off the blender, add the baking powder, and pulse exactly 3 times — just enough to incorporate it without deflating the batter.

  6. 6

    Pour the batter into the prepared pan and bake for 35 minutes, until a skewer inserted in the center comes out clean.

  7. 7

    While the cake bakes, make the syrup: combine the orange juice, sugar, and margarine in a small saucepan. Bring to a boil, then remove from heat.

  8. 8

    As soon as the cake comes out of the oven, poke holes across the surface and pour the warm syrup all over the hot cake so it absorbs completely.

💡 Chef's Tip

Use organic oranges and stir a teaspoon of fresh zest into the batter before baking for a more vibrant citrus flavor. The warm syrup on a hot cake is the secret behind the irresistible moistness — never skip it!
