Ingredients

1½ pounds (about 4 large) Granny Smith apples, peeled, cored, cut into 8 wedges each, then sliced ⅛-inch thick crosswise
1 tablespoon Calvados (or rum, apple brandy, or apple juice)
1 teaspoon fresh lemon juice
1 teaspoon ground cinnamon
1 cup + 2 tablespoons all-purpose flour, divided
1 cup + 1 tablespoon granulated sugar, divided
2 teaspoons baking powder
½ teaspoon salt
1 large egg + 2 large egg yolks, room temperature
1 cup neutral vegetable oil (like canola)
1 cup whole milk, room temperature
1 teaspoon pure vanilla extract

Instructions

Get cozy in the kitchen — Preheat your oven to 325°F (165°C) and position the rack in the lower-middle spot. Generously grease a 9- or 10-inch springform or round cake pan, then line the bottom with parchment paper for easy release.
Prep those gorgeous apples — Peel, core, and slice your Granny Smith apples thinly (⅛ inch). Toss them in a bowl with the Calvados (or substitute), lemon juice, and cinnamon. Let them mingle for 15 minutes—this infuses flavor and prevents browning.
Whisk the dry magic — In a medium bowl, whisk together 1 cup flour, 1 cup sugar, baking powder, and salt until evenly combined. This is your fluffy base!
Create the creamy custard batter — In a large bowl, whisk the egg, egg yolks, oil, milk, and vanilla until smooth and silky. Gradually add the dry ingredients, whisking gently just until no lumps remain—don't overdo it for that tender texture.
Fold in the apple love — Toss the apple slices with the remaining 2 tablespoons flour to coat lightly (this prevents sinking). Gently fold most of the apples into the batter, saving a handful for the top.
Assemble with care — Pour the batter into your prepared pan. Arrange the reserved apple slices prettily on top in a circular pattern—they'll create beautiful layers as it bakes.
Sweet finish touch — Sprinkle the remaining 1 tablespoon sugar evenly over the top. This will caramelize into a gorgeous, crisp crust.
Bake to golden perfection — Slide into the oven and bake for 1 hour 10–20 minutes, until the top is deep golden, the edges pull away slightly, and a toothpick in the center comes out mostly clean with moist crumbs (not wet batter).
Cool like a pro — Place the pan on a wire rack and let it cool for 30 minutes. Run a knife around the edges, then release from the springform (or invert if using a regular pan).
Serve with joy — Dust lightly with powdered sugar if desired. Slice and enjoy warm or at room temp—pair with whipped cream, ice cream, or just as is for pure bliss!

Notes

This cake's magic lies in its custardy interior from extra yolks and oil—it's meant to be dense and moist, not fluffy like traditional cake. If the top browns too quickly, tent loosely with foil after 45 minutes. Always use fresh baking powder for best rise.

Recipe Tips and Tricks

Use firm, tart apples like Granny Smith or Honeycrisp—they hold their shape beautifully during baking and balance the sweetness with bright acidity. Slice them thinly and uniformly (about ⅛ inch) for even distribution and that classic layered look.

Don’t overmix the batter once eggs are added; gentle folding keeps the texture tender and custardy. For the best rise and crisp top, bake on the lower-middle oven rack at a moderate temperature. If your apples are extra juicy, toss them briefly in a hot pan to release moisture and prevent a soggy bottom.

Let the cake cool in the pan for at least 30 minutes before unmolding—it firms up as it cools. Dust with powdered sugar right before serving for that pretty finish, and serve slightly warm with whipped cream or vanilla ice cream to elevate the experience.

Test doneness with a toothpick in the center—it should come out mostly clean with a few moist crumbs.

Ingredients Notes

Granny Smith apples (1½ pounds, about 4 large) are the star here—their tartness cuts through the richness while staying firm after baking; peel, core, and slice them thinly crosswise for the best texture.

All-purpose flour provides structure without making it dense; use the spoon-and-level method for accuracy. Granulated sugar sweetens gently and creates that signature crisp top layer when sprinkled on before baking.

Baking powder gives a light lift to the custard-like base. Eggs (1 whole plus 2 yolks) add richness and that silky, custardy mouthfeel—room temperature helps everything emulsify smoothly. Vegetable oil (neutral like canola) keeps the cake incredibly moist for days, unlike butter which can firm up more.

Whole milk contributes creaminess; don’t substitute low-fat or the texture won’t be as luxurious. Vanilla extract brings warm, aromatic depth—pure is best. A touch of cinnamon enhances the apples without overpowering, while optional Calvados (apple brandy) or rum adds sophisticated French flair (substitute with apple juice for alcohol-free).

Lemon juice prevents browning and brightens flavors. Salt balances sweetness, and a final sprinkle of sugar on top caramelizes for crunch.

Variations and Substitutions

For a boozy twist, swap Calvados or rum into the apples or batter for authentic Norman flavor; use apple juice or orange juice for a kid-friendly, alcohol-free version. Experiment with apple varieties—mix tart Granny Smith with sweeter Honeycrisp or Pink Lady for layered sweetness.

Add warm spices like a pinch of nutmeg, cardamom, or Chinese five-spice for exotic depth. Make it dairy-free with almond or oat milk and oil (already dairy-free in base). Gluten-free? Swap in a 1:1 GF flour blend. For extra indulgence, fold in a handful of chopped walnuts, pecans, or raisins into the apples.

Turn it into mini cakes using a muffin tin (reduce bake time to 25-30 minutes). For a more tart version, increase lemon juice or add orange zest. If you prefer less custard and more cake, reduce egg yolks or add more flour (but test small). Top with a maple-ginger custard sauce drizzle post-bake for gourmet flair, or serve with caramel sauce instead of plain.

Storage Options

Store the cooled cake in an airtight container at room temperature for up to 2 days (the top stays crispest this way). For longer freshness, refrigerate up to 5 days—bring to room temperature or warm slices gently in the microwave for 10-15 seconds to revive the moist texture.

It freezes beautifully: wrap individual slices tightly in plastic wrap and foil, or the whole cake in plastic; freeze up to 2 months. Thaw overnight in the fridge and warm before serving.
