Ingredients You’ll Need

To get the best result, high-quality, whole ingredients make all the difference.

For the Batter

Plain Greek Yogurt (3/4 cup / 170g): Use full-fat or 2% Greek yogurt for optimal creaminess and texture. Ensure it is thick and strained.
Large Eggs (3 room temperature): Eggs provide structural stability and help the custard set smoothly without flour.
Cornstarch or Arrowroot Starch (3 tablespoons / 24g): Binds the moisture and gives the cake its delicate, sliceable structure.
Sweetener of Choice (1/3 cup / 80ml): Pure maple syrup, raw honey, or granulated monk fruit sweetener all work beautifully.
Pure Vanilla Extract (1 teaspoon): Adds warmth and rounds out the tangy yogurt notes.
Ground Cinnamon (1 teaspoon): The quintessential pairing for baked apples.
Ground Nutmeg (1/4 teaspoon, optional): Adds a subtle bakery-style depth.
Fine Sea Salt (1/4 teaspoon): Enhances the sweet apple flavors.

For the Fruit & Layering

Apples (2 medium to large, approximately 300g peeled and cored): Honeycrisp, Fuji, Gala, or Granny Smith work best. Thinly sliced (using a mandoline or sharp chef’s knife).
Lemon Juice (1 tablespoon): Tossed with the apples to prevent browning and brighten the flavor.
Powdered Sugar or Erythritol (Optional): For dusting before serving.

Step-by-Step Baking Instructions

Step 1: Prep Your Oven and Pan

Preheat your oven to 350°F (175°C). Line an 8-inch (20 cm) round cake pan or springform pan with parchment paper, ensuring the paper comes up along the sides. Lightly spray with non-stick cooking spray to prevent sticking.

Step 2: Slice the Apples

Peel, core, and slice the apples very thinly (about 1/8-inch or 2–3 mm thick). Thin slices ensure the apples soften evenly and integrate smoothly into the custard base. Toss the apple slices in a small bowl with 1 tablespoon of fresh lemon juice and a pinch of cinnamon. Set aside.

Step 3: Whisk the Custard Base

In a medium mixing bowl, whisk together the eggs, sweetener, and vanilla extract until smooth and lightened in color (about 1 minute). Add the Greek yogurt and whisk vigorously until no lumps remain and the mixture is completely uniform.

Step 4: Add Dry Ingredients

Sift in the cornstarch, ground cinnamon, nutmeg, and sea salt. Whisk gently until the starch is fully dissolved into a glossy batter.

Step 5: Combine & Layer

Fold about two-thirds of the sliced apples directly into the batter using a spatula, ensuring every slice is coated. Pour the mixture into your prepared cake pan, smoothing the surface with a spatula. Arrange the remaining apple slices neatly on top in a concentric pattern for a beautiful finished look.

Step 6: Bake to Perfection

Place the pan on the center rack of your oven and bake for 40 to 50 minutes.

How to check for doneness: The edges should be set, golden brown, and slightly pulled away from the sides of the pan. The center should have a slight jiggle (like a cheesecake or panna cotta) but shouldn’t feel wet or liquid.

Step 7: Cool and Chill

Remove from the oven and allow the cake to cool inside the pan at room temperature for 30 minutes. Once warm, transfer the cake to the refrigerator to chill for at least 1 hour before slicing. Chilling allows the flourless structure to set fully into a clean, sliceable texture.

Pro Tips for Recipe Success

Don’t Skip the Chilling Phase: Because this cake contains no grain flours, slicing it hot will cause it to fall apart. Cooling completely in the fridge binds the eggs and cornstarch, creating clean, bakery-quality slices.
Apple Selection: If you prefer a tart flavor contrast to the sweet custard, mix one Granny Smith apple with one Honeycrisp apple.
Parchment Paper Slings: Leave parchment overhang on the sides of your baking dish so you can effortlessly lift the cooled cake out onto a platter.

Storage & Shelf Life (How Long It Lasts)

Proper storage ensures your flourless apple cake remains fresh, creamy, and flavorful throughout the week.

Refrigeration: Store leftover slices in an airtight container in the refrigerator. This cake lasts for up to 5 days chilled. The flavors often deepen by day two as the apples release their natural sugars into the custard!
Freezing: Slice the cake into individual portions. Wrap each slice tightly in parchment paper and aluminum foil, then store in a freezer-safe bag. It lasts for up to 2 months in the freezer. Thaw overnight in the fridge before serving.
Serving Temperature: Serve chilled straight from the fridge, or let it rest at room temperature for 10 minutes prior to serving.
