Instructions
Prepare the Cake Pan
Grease a 9-inch round cake pan (without a removable bottom) with butter. Line the bottom with a round of parchment paper.
Time: PT5M
Macerate the Peaches
Wash and thinly slice 3-4 ripe peaches (unpeeled) into wedges. Place in a bowl. Zest about 2 teaspoons of lemon and reserve zest for cake batter. Squeeze juice from half the lemon (about 2 Tbsp) over peaches. Add 1/3 cup Demerara sugar. Gently toss to coat. Let sit for 15-20 minutes to draw out juices.
Time: PT20M
Cook the Polenta
In a 2-quart saucier or saucepan, heat 1 1/4 cups whole milk over medium heat until just simmering. Gradually whisk in 1/2 cup coarse ground cornmeal (polenta), whisking constantly to prevent lumps. Cook for about 1-2 minutes until thick and porridgy. Remove from heat. Stir in 1 teaspoon vanilla extract. Transfer to a bowl and let cool to room temperature.
Time: PT10M
Temperature: Medium heat
Reduce Peach Syrup
Strain macerated peaches over a fine mesh strainer, collecting juices in the saucier. Let peaches drain while you prepare the syrup. Simmer the peach juices over medium heat until reduced by more than half and thickened to a syrup (about 5-7 minutes). Pour syrup into the prepared cake pan, tilting to coat the bottom.
Time: PT10M
Temperature: Medium heat
Arrange Peaches in Pan
Arrange the drained peach slices over the syrup in the cake pan in a decorative pattern (such as concentric circles or a rosette). Use all the fruit, filling in gaps as needed.
Time: PT5M
Mix Dry Ingredients
In a bowl or quart container, combine 1 cup all-purpose flour, 1 1/2 teaspoons baking powder, and 3/4 teaspoon kosher salt. Set aside.
Time: PT2M
Cream Butter, Sugar, and Lemon Zest
In the bowl of a stand mixer fitted with paddle attachment, combine 10 tablespoons room temperature unsalted butter and 3/4 cup granulated sugar (with reserved lemon zest). Rub zest into sugar with fingertips to release oils. Beat on medium speed until light and fluffy, about 3-4 minutes.
Time: PT5M
Add Eggs
Add 2 large eggs, one at a time, beating well after each addition on medium speed. Scrape down bowl as needed.
Time: PT2M
Alternate Dry and Polenta Mixtures
With mixer on low, add one-third of dry ingredients, then half of cooled polenta mixture, mixing just until incorporated. Repeat with half remaining dry, then remaining polenta, then final dry ingredients. Stop mixer as soon as flour disappears.
Time: PT5M
Fold and Finish Batter
Remove bowl from mixer. Use a rubber spatula to fold batter by hand, scraping bottom and sides to ensure even mixing. Look for any pockets of butter or flour and incorporate gently.
Time: PT2M
Dollop and Smooth Batter
Dollop batter evenly over arranged peaches in pan. Use an offset spatula to gently smooth into an even layer, taking care not to disturb the fruit pattern.
Time: PT3M
Bake the Cake
Bake cake at 350°F (middle rack) for 45-50 minutes, until top is golden brown, center is domed and springy, and a tester inserted in the center comes out clean.
Time: PT45M
Temperature: 350°F
Cool and Unmold
Let cake cool in pan on a rack for 10 minutes. Run an offset spatula around the edge. Invert cake onto a wire rack: place rack over pan, grip both, and flip. Carefully lift off pan. Remove parchment if stuck to cake. Let cool completely before slicing.
Time: PT15M
Serve
Slice and serve at room temperature. Optional: top with whipped cream or vanilla ice cream.
Time: PT1M
Cleanup
Wash all bowls, mixer parts, saucepan, utensils, and wipe down counters. Soak pan if syrup is stuck. Dry and store equipment.
Time: PT20M

Cake is soggy or underbaked in the center.
Reduce peach juices thoroughly before adding to pan. Bake until a tester comes out clean.
Batter is lumpy.
Whisk polenta mixture smooth before adding. Alternate dry and wet ingredients in mixer.
Fruit layer is pale or bland.
Use ripe, in-season peaches. Do not skip maceration and syrup reduction.

Make-Ahead Tips
- Cake is best the day it’s made, but you can bake it up to 1 day ahead and store at room temperature, covered.
- Peaches can be sliced and macerated up to 2 hours ahead; keep refrigerated if longer.

What are the authentic traditional ingredients for an American upside-down peach cake versus the substitutes used in Claire Saffitz's Upside-Down Peach Polenta Cake?
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.
What other American dishes pair well with Claire Saffitz's Upside-Down Peach Polenta Cake?
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.
What are the most common mistakes to avoid when making Claire Saffitz's Upside-Down Peach Polenta Cake at home?
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.
Why does this Claire Saffitz's Upside-Down Peach Polenta Cake recipe use cooked polenta for the cake base instead of traditional flour?
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.
What texture and appearance should I look for when making Claire Saffitz's Upside-Down Peach Polenta Cake to know it is done correctly?
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.
