You fancy something sweet — but not with tons of sugar or fat, please. This is exactly where the hot air fryer comes into its own! Because it can prepare more than just chips and chicken wings. Healthy desserts can also be made in the Airfryer in no time at all — crispy, warm, fruity, or chocolaty. FITBOOK editor Julia Freiberger has put together four dessert recipes that are not only easy to prepare but also do not contain any refined sugar — ideal for anyone who wants to enjoy a healthy treat.

Warm Baked Apples with Walnut Crumble from the Air Fryer

When I was little, my mom often made baked apples in the oven — with nuts and honey on top. I still remember my sister and I sitting spellbound in front of the oven and watching the apples slowly soften. And that smell! The whole apartment smelled of it — sweet, warm, simply heavenly. Years later, I developed the recipe further in my own way, with a little extra: a crispy crumble. Because it’s more than just a baked apple for me, I named my recipe “Crumsies.” It’s quick to make, doesn’t need any refined sugar — and works perfectly in the air fryer.

Ingredients (for 2 portions)

• 2 apples
• 1 tsp coconut oil
• ½ tsp cinnamon

For the crumble:

• 40 g rolled oats
• 40 g walnuts
• 1 tsp coconut blossom sugar
• ½ tsp cinnamon
• 40 g applesauce

Preparation

1. First, wash the apples, cut them in half, and remove the core.
2. Then, cut a piece of baking paper to fit the air fryer and place it inside.
3. Brush the apple halves with coconut oil, sprinkle with cinnamon, and place them in the air fryer with a little space between them.
4. For the crumble, finely grind the rolled oats and walnuts in a blender and knead with the apple sauce, coconut blossom sugar, and cinnamon.
5. Spread the mixture in small pieces over the apples and on the baking paper.
6. Then bake in the Airfryer at 160 degrees for about 15 minutes.

Tip: What I also like to do: Top with some dark chocolate chips and soy yogurt. Remove the remaining crumble from the baking paper and sprinkle over the finished apples.

Fluffy Chocolate Banana Bites

Quick to make, chocolaty, and still healthy — these little banana bites with cocoa and nut butter are the perfect snack when a sweet tooth strikes. Bananas not only provide natural sweetness but also valuable nutrients: they are rich in carbohydrates, fiber, and potassium — an important mineral for muscles and nerves. It also provides vitamins such as B6 and C as well as minerals such as magnesium, iron, zinc, and iodine. Combined with unsweetened cocoa and a dollop of nut butter, the result is a nutrient-rich snack that can be ideally integrated into a balanced diet.

Ingredients (for 2 portions)

• 1 ripe banana
• 2 tsp unsweetened baking cocoa
• 1 tsp almond butter or peanut butter
• 1 tsp maple syrup (optional)
• 2 tbsp fine rolled oats
• 1 pinch of salt

Preparation

1. Mash the banana with a fork and mix with the cocoa, nut butter, maple syrup, salt, and oats.
2. Form small balls or “bites” and place them on a piece of baking paper in the air fryer.
3. Bake at 160 degrees for about ten minutes.

Tip: Enjoy warm or keep cold as a snack. If you like, you can refine them with a hint of cinnamon.

Protein Chocolate Muffins from the Air Fryer

There are days when I just really fancy muffins. Preferably nice and moist and chocolaty — but without the amount of sugar that they usually contain. So that I can enjoy them without feeling guilty, I have developed this recipe: Protein chocolate muffins from the air fryer.

Fluffy, chocolaty, and full of protein — perfect as a healthy snack or small dessert after training. No added sugar, but with nutritious ingredients and full of flavor.

Ingredients (for 4 small muffins / 2 portions)

• 1 ripe banana
• 1 egg
• 30 g protein powder (e.g. vanilla or chocolate)
• 1 tsp baking cocoa
• 1 tbsp rolled oats
• 1 tsp baking powder
• 1 tsp almond butter
• Optional: a little cinnamon or vanilla

Preparation

1. Simply mix all the ingredients in a bowl to form a smooth batter.
2. Pour the batter into small silicone molds (fill no more than two-thirds full).
3. Place the molds in the air fryer and bake at 320 degrees Fahrenheit for about 10-12 minutes.

Tip: For a sweet touch, press dark chocolate drops or berries into the center — this creates a juicy center when cut open.
