Claire Saffitz's Upside-Down Peach Polenta Cake blends the classic American upside‑down peach cake with Italian‑inspired polenta, reflecting the multicultural influences in modern American desserts. The dish celebrates peak‑season peaches, a staple of American summer, and showcases how home bakers can elevate traditional comfort foods with sophisticated textures.

In the American South, upside‑down peach cakes are often made with a buttery biscuit or cake base and a caramelized peach topping, using simple flour and cornmeal. Claire Saffitz's version replaces the typical flour base with cooked polenta, adding a creamy, porridgy texture that differentiates it from the denser Southern biscuits while still honoring the caramelized peach glaze.

The cake is usually served slightly warm or at room temperature, allowing the syrupy peach glaze to stay glossy. It is often accompanied by a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream, making it a refreshing centerpiece for picnics, barbecues, and brunches during the summer months.

Upside‑down peach cakes are commonly featured at Fourth of July picnics, summer birthday parties, and harvest festivals that celebrate fresh, local fruit. Claire Saffitz's version, with its elegant presentation, is also popular for more formal gatherings such as garden parties and bridal brunches.

The cake bridges classic American fruit desserts—like peach cobbler and upside‑down cake—with a contemporary, ingredient‑focused twist. By incorporating polenta, it adds a texture reminiscent of Italian desserts, illustrating the evolving, fusion‑friendly nature of American pastry culture.

Traditional recipes rely on all‑purpose flour, butter, sugar, eggs, and fresh peaches, sometimes adding a bit of cornmeal for texture. Claire Saffitz substitutes cooked polenta for part of the flour, which provides extra moisture and a subtle corn flavor while keeping the cake tender and slightly crumbly.

Pair the cake with a light citrus salad, a scoop of homemade vanilla ice cream, or a serving of spiced pecan praline for contrast. A glass of chilled Riesling or a classic American sweet tea also complements the peach‑forward flavors.

Common pitfalls include over‑mixing the polenta batter, which can make the cake tough, and under‑caramelizing the peach topping, leading to a watery glaze. Additionally, using overly ripe peaches can cause the fruit to release too much juice, preventing a firm caramel crust.

Cooked polenta adds moisture and a naturally creamy crumb that helps the cake stay tender even after being inverted with the fruit glaze. It also introduces a subtle corn flavor that complements the sweetness of the peaches, creating a distinctive texture not found in a standard flour‑based cake.

The cake should have a golden‑brown crust on the bottom where the peaches caramelize, and the polenta layer should be set but still slightly springy to the touch. When a toothpick inserted into the center comes out clean with just a few moist crumbs, the cake is perfectly baked.
