Yogurt Sponge Cake (Bizcocho de Yogur)

INGREDIENTS

  • 1 container (125g) plain yogurt (use the empty container to measure the rest)
  • 1 container neutral oil (sunflower or vegetable oil)
  • 2 containers granulated sugar
  • 3 containers all-purpose flour
  • 3 large eggs
  • 1 packet baking powder (about 16 g or 1 tbsp)
  • Zest of 1 lemon (optional)
  • A pinch of salt
  • Butter or oil for greasing the pan

INSTRUCTIONS

  1. Preheat the oven to 350°F (175°C). Grease a 9-inch round or loaf pan and lightly flour it.
  2. In a large mixing bowl, whisk the eggs and sugar together until light and fluffy.
  3. Add the yogurt and mix well. Use the empty yogurt container to measure the rest of the ingredients.
  4. Add the oil and lemon zest (if using), and whisk until fully combined.
  5. In a separate bowl, mix the flour, baking powder, and salt.
  6. Gradually fold the dry ingredients into the wet mixture, mixing until just combined—do not overmix.
  7. Pour the batter into the prepared pan and smooth the top.
  8. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
  9. Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Optional: Dust with powdered sugar before serving.
