Why this apple cake is good for your longevity diet

Now the nutritionist in me is coming out for a moment, but don’t worry, I’ll keep it brief. 😉 This cake isn’t just delicious – it’s functional, too.

Apples provide fiber and phytochemicals like polyphenols. These can support your cellular health and have antioxidant effects. Plus, your gut bacteria will be very happy about it.

Skyr packs a good dose of protein. This not only helps with muscle building but also ensures that you don’t crash right after eating the cake.

Almonds and hazelnuts provide healthy fats and magnesium, among other nutrients. They also help your body better absorb fat-soluble vitamins – exactly what we want in a modern longevity diet.

Erythritol provides sweetness without causing significant blood sugar spikes. This means your energy levels stay stable, and you won’t experience that typical post-dessert crash. If you don’t like erythritol or have trouble digesting it, you can use alternatives such as:

• Xylitol: similar sweetness to sugar, moderate effect on blood sugar, can cause digestive issues in large quantities, toxic to dogs

• Date sugar: natural, contains fiber and micronutrients, but raises blood sugar more than erythritol

• Coconut blossom sugar: slightly lower glycemic index than table sugar, but still metabolized as sugar

• Glycine: an amino acid with the sweetness of sugar, does not affect blood sugar, may also support sleep quality and collagen production, has a slight taste of its own

Fewer ingredients, more impact

What makes this recipe special is its simplicity. No long ingredient lists, no complicated steps, and yet a delicious result. The combination of juicy apples, creamy skyr, and a nutty base creates the perfect balance of:

Sweetness
Freshness
Creaminess
Light satiety

And honestly: Sometimes it’s exactly these simple recipes that you end up making most often.

Ingredients

500 g apples
4 eggs
250 g skyr (e.g., made from soy)
80 g ground almonds or hazelnuts
60 g erythritol

Optional

Pinch of salt
Cinnamon or vanilla
A little lemon juice for the apples

Instructions

Preheat the oven to 180 degrees Celsius (top and bottom heat).
Thinly slice the apples and, if desired, toss them with a little lemon juice to prevent them from browning.
In a bowl, whisk the eggs together with the skyr and erythritol until smooth and well combined.
Then stir in the ground almonds. Optionally, add cinnamon, vanilla, and a pinch of salt.
Fold the prepared apples into the batter and mix everything evenly.
Grease a small baking pan or line it with parchment paper and pour the batter into it.
Bake the cake at 180 degrees for about 40 to 50 minutes, until it is golden brown. Baking time may vary slightly depending on the oven.
After baking, let the apple cake cool completely so it develops its final texture and is easy to slice.
