About This Light Apple Charlotte
Traditional sharlotka is a beloved Russian sponge cake made with apples, sugar, and eggs. Here, we’ve eliminated butter and refined sugar, substituting honey for sweetness and oat flakes for a subtle nutty texture. The key innovation: using only egg whites, which are beaten with honey until stiff peaks form. This creates an exceptionally light batter that bakes into a pillow-soft cake. The apples—ideally tart-sweet varieties like Granny Smith or Fuji—provide moisture and a gentle tang. Combined with warming spices like cinnamon and ginger, this charlotte captures the essence of autumn in every slice. For best results, use a high-quality immersion blender to grind the oats to a fine flour.
Ingredients
- Kyslo-sladkie yabloki (sweet-sour apples) – 2 pieces (about 300 g)
- Med (honey) – 50 g
- Moloko 1% (low-fat milk) – 200 ml
- Yaytsa (eggs) – 3, whites only
- Ovsyanye khlopya (oat flakes) – 80 g
- Koritsa (cinnamon) – 7 g (about 1 tbsp)
- Molotyy imbir (ground ginger) – 3 g (about 1 tsp)

- Solochnoye maslo (butter) – 20 g for greasing
Note: Using a citrus juicer helps extract every drop of lemon juice efficiently.
Step-by-Step Instructions
Step 1: Whip the Whites with Honey
Separate the eggs, reserving only the whites. (Discard the yolks or save for another use.) Chill the bowl and whisk attachment in the refrigerator for 10 minutes. Beat the egg whites together with the honey using an electric mixer until soft peaks form—the mixture should become white and frothy, just before stiff peaks. A reliable mixer ensures consistent results.
Step 2: Grind Oat Flakes and Combine
Grind the oat flakes into a coarse flour using a coffee grinder or a food processor. Add the ground oats to the egg white mixture, then pour in the milk, cinnamon, and ginger. Mix gently with a spatula until just combined—overmixing will deflate the foam.
Step 3: Activate the Soda
Squeeze the lemon half to obtain about 1 tablespoon of juice. Use a few drops to dissolve the baking soda—it will fizz. Immediately fold the soda mixture into the batter and whisk until smooth. Reserve the remaining lemon juice for the apples. A lemon juicer simplifies this step.
Step 4: Prepare the Apples
Wash, dry, and peel the apples. Cut them into small cubes (about 1 cm). Immediately toss the apple cubes with the reserved lemon juice to prevent browning. This also adds a bright, fruity note.
Step 5: Assemble and Bake
Grease a round cake pan (about 20 cm diameter) with the butter and dust it lightly with flour to prevent sticking. Spread the apple cubes evenly in the pan, then pour the batter over them. Smooth the top with a spatula. Preheat the oven to 200°C (400°F). Use a convection oven for even heat distribution.
Step 6: Bake Until Golden
Bake for 30–40 minutes, until the top is deep golden brown and a skewer inserted into the center comes out clean. Let cool in the pan for 10 minutes, then transfer to a wire rack. Before serving, dust with powdered sugar or top with fresh berries. For a precise temperature, a digital thermometer is handy.
Tips for Perfect Sharlotka
Chill your mixing bowl and whisk for at least 10 minutes before beating the whites—this creates volume. Use a cool refrigerator to store the bowl. Avoid opening the oven during the first 20 minutes of baking to prevent collapse. If using a countertop convection oven, reduce temperature by 10°C and check earlier. For a gluten-free version, use certified gluten-free oat flakes. The cake is best served warm with a dollop of Greek yogurt.
Variations to Try
Swap honey with maple syrup for a different sweetness profile. Add 30 g of chopped walnuts or almonds for crunch. Replace half the apples with pears or quince. Infuse the milk with a vanilla bean before mixing. For a richer texture, fold in 2 tablespoons of dark chocolate chips. Spice lovers can increase ginger and add a pinch of nutmeg. This versatile base also works as a Catalan-style sponge with different fruits.
Frequently Asked Questions
Can I use whole eggs instead of just whites?
Yes, but the cake will be denser and less airy. The recipe came about for a lightened version, so using yolks adds fat and weight. If you prefer, substitute the whites of 3 eggs with a mix of 1 whole egg and 2 whites.
What if I don't have oat flakes?
You can replace the oat flakes with an equal weight of whole-wheat flour or all-purpose flour. The texture will be slightly different—less rustic—but still delicious. For a finer crumb, sift the flour together with the spices.
How do I keep the apples from sinking?
Toss the diced apples in a tablespoon of the oat flour (or all-purpose flour) before adding to the batter. This helps suspend them evenly. Also ensure the batter is thick enough; if too runny, add a little more ground oats.
Can I make this dairy-free?
Absolutely. Substitute the milk with almond milk, oat milk, or any plant-based alternative. Use coconut oil or vegan butter for greasing. The cake will still rise beautifully.
How should I store leftovers?
Wrap the cooled charlotte in plastic wrap and keep at room temperature for up to 2 days, or refrigerate for 4 days. Reheat slices in a toaster oven or microwave for 15 seconds. The cake can also be frozen for up to 1 month—thaw overnight in the fridge.
