“Orange zest perfumes the yogurt crumb while pistachios added in two stages keep their crunch.”
Olive oil cakes stay moist for the better part of a week, which is the practical reason to make one. This is also the cheapest way to use pistachios, since a modest three-quarter cup spread through the batter and over the top reads as far more than it is. Eight slices, one bowl each of wet and dry.
Zest is where the flavor lives and where it is easiest to go wrong. Take only the orange layer and stop at the white pith, which is bitter and will run through everything. Two tablespoons is roughly three oranges, so zest them all before you juice anything. The nuts split into two additions so some stay crunchy on top.
🍊 The promise: An olive-oil and yogurt cake that stays moist for days, with nuts added in two stages so some keep their snap — about 80 minutes including cooling.


Half the pistachios are tossed with the flour so they stay suspended in the batter, and the rest arrive halfway through the bake so they toast on the surface instead of steaming inside the crumb.
Olive oil carries the citrus further than butter would, but a peppery bottle fights it; a mild, buttery oil is the one to reach for here.
Grease a 9-inch (23 cm) round pan, line the base with parchment, and heat the oven to 350°F (175°C). A lined base matters here because the yogurt batter clings hard to bare metal once it cools.

Toast the pistachios in a dry pan over medium heat for 4 minutes, until they smell green and grassy, then cool them and chop into deliberately uneven pieces. The larger shards give the finished slices visible crunch.

Whisk the flour, baking powder, kosher salt, and half the chopped pistachios in a bowl. Coating the nuts in flour first keeps them suspended through the batter instead of sinking to the bottom during the bake.

In a second bowl, whisk the yogurt, eggs, olive oil, sugar, and orange zest until the mixture is smooth and smells strongly of citrus. Fold the dry ingredients in with a spatula, stopping while a few streaks remain.

Scrape the batter into the pan and bake 34–40 minutes, scattering the remaining pistachios over the top halfway through. It is ready when the surface springs back and the center reads 200°F (93°C) on a thermometer.

Cool the cake in its pan on a rack for 20 minutes, until the sides shrink slightly away from the edge. Run a knife around it, invert onto the rack, peel off the parchment, and cool before slicing.

The crumb is moist and golden with whole pistachio pieces suspended throughout and a clear scent of orange zest. If the top is set and coloring before a thermometer reads 200°F (93°C) in the middle, tent it with foil and give it another 5 to 8 minutes.
Rub orange zest into the sugar and reserve the darkest toasted pistachios for the cake surface.
