The apple bundt cake without sugar and butter in the air fryer is a simple, wholesome recipe within everyone’s reach, ideal for those who want a soft, light cake without giving up the taste of tradition. The apple bundt cake is one of the most loved homemade desserts: fragrant, tender and full of apples, it immediately recalls the authentic flavors of old-time snacks. In this version I chose to eliminate both sugar and butter, making it perfect for those following a more balanced or low-calorie diet, without losing the typical goodness of this cake.
Instead of sugar we used erythritol, a zero-calorie natural sweetener that does not alter the flavor and still gives a pleasant sweetness. To replace butter we chose neutral vegetable oil which makes the batter soft and moist. Cooking in the air fryer makes everything faster, more practical and lighter, with an even browning and without the need for a traditional oven.
This bundt cake is perfect for breakfast, perhaps accompanied by a cup of tea or coffee, or for an afternoon snack for a sweet break without guilt.

Steps for the apple bundt cake without sugar and butter in the air fryer:
Grease a 7-inch bundt pan, then dust it with flour.
Cut half a Renetta apple in half, remove the core and peel, then slice it thinly. Put the slices in a bowl and add some lemon juice, toss well (if you like you can add a little erythritol for extra sweetness).
In a bowl put the egg and the sweetener and whisk well by hand, add the plain yogurt and the vegetable oil, mix well, then finally add the sifted flour and baking powder and cinnamon to taste.
Blend the ingredients well until you obtain a smooth and homogeneous batter.
Pour the batter into the pan, level it well then place the apple slices on top, slightly pressing them into the batter.
Preheat the air fryer to 302°F, then bake your bundt cake at 302°F for about 23 minutes. Do the toothpick test (we used an air fryer with dual heating elements; if you have a single element continue baking for a few more minutes. If the top appears cooked but the inside is still soft, cover it with aluminum foil tightly applied to the pan to prevent it from flying up and touching the heating element, and continue baking for another 3–4 minutes).
Let your bundt cake cool, then transfer it to a serving plate.
