Ingredients
Method
Prep
- Heat the oven to 175 C / 350 F. Grease a 23 cm / 9-inch round cake pan and line the base with parchment paper.
- Toast all 90 g of pistachios in a dry 25 cm / 10-inch skillet over medium heat for 3 to 4 minutes, shaking the pan often, until fragrant and lightly colored. Cool, then chop 60 g finely for the batter and 30 g more roughly for topping.
Mix the batter
- In a large bowl, whisk the olive oil, sugar, and eggs together for about 2 minutes, until pale, thick, and slightly foamy.
- Whisk in the orange zest, orange juice, and yogurt until smooth.
- In a second bowl, whisk together the flour, baking powder, and salt.
- Add the dry ingredients to the wet mixture in two batches, folding gently with a spatula just until no streaks of flour remain. Don't overmix or the cake will turn dense.
- Fold in the 60 g of finely chopped toasted pistachios.
Bake and finish
- Pour the batter into the prepared pan and smooth the top with a spatula.
- Bake for 42 to 48 minutes, until a skewer inserted in the center comes out clean and the top springs back when lightly pressed. Check at 40 minutes since darker pans can bake faster.
- Cool the cake in the pan for 15 minutes, then turn it out onto a wire rack and let it cool completely before glazing.
- Whisk the powdered sugar and 2 tbsp orange juice together until smooth and pourable, adding a few extra drops of juice if it's too thick.
- Pour the glaze over the cooled cake and immediately scatter over the remaining 30 g of chopped pistachios. Slice and serve at room temperature.
Notes
- Toast pistachios before chopping, it makes a real difference in flavor.
- Cool the cake fully before glazing or the glaze slides off.
- A cheap olive oil will taste flat, use one you'd eat plain.
- Yogurt can be swapped for sour cream in the same amount.
