This pistachio-lime polenta cake is an easy dessert or snack cake made with ground pistachios, polenta, lime juice and zest, sugar, and a mixture of olive oil and butter. Despite the richness that the nuts, oil, and butter lend to this lightly sweetened cake, it is very light and delicate in texture.

This cake is moist, delicate, light, gently nutty, and zesty all at the same time. It is the perfect tea cake, or serve as a dessert with a dollop of Greek yogurt on the side. The olive oil pairs very well with the lime and pistachio and makes for a very moist crumb.–Kathy Kordalis
Pistachio-Lime Polenta Cake FAQs
In many stores, yes. Superfine sugar also goes by the names: caster, ultrafine, or bar sugar. But, you can also make your own by blitzing granulated sugar in a food processor until finely ground, but not powdery.
Always use superfine sugar if a recipe calls for it specifically. There’s probably a good reason. Generally, because the texture of superfine sugar is much finer than regular sugar, it will melt and incorporate itself into batters, sauces, and bases more smoothly and quickly.
This cake will keep nicely for about four days. Let it cool completely, then place in an airtight container. It should be stored in a cool area (not necessarily a fridge although that’s ok too, but definitely keep it away from heat sources).
