Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or lightly grease it.

Peel, core, and finely dice the two large apples. Set them aside for later.

In a large mixing bowl, combine 1 cup (110 g) of whole wheat flour, 1/2 cup (45 g) of rolled oats, 1 teaspoon of ground cinnamon, and 1 1/2 teaspoons of baking powder. Mix these dry ingredients thoroughly.

In another bowl, beat 1 egg and add 5 packets of sweetener (adjust to your preferred level of sweetness) and 2 tablespoons of vegetable oil. Mix until well combined.

Gradually add the wet mixture to the dry ingredients, stirring until just combined. Avoid overmixing, as this can make the muffins tough.

Gently fold the finely diced apples into the muffin batter. Ensure an even distribution of apple pieces.

Portion the batter into the prepared muffin cups, filling each one about 3/4 full. This allows room for the muffins to rise while baking.

Place the muffin tin in the preheated oven and bake for 20-25 minutes or until a toothpick inserted into the center of a muffin comes out clean.

Allow the muffins to cool in the tin for a few minutes, then transfer them to a wire rack to cool completely. Once cooled, your healthier Apple Muffins are ready to enjoy.
