Line an 8×8 baking dish with parchment paper, letting the edges overhang for easy lifting. Grease lightly to prevent sticking.

In a large bowl, combine rolled oats, cinnamon, nutmeg, baking powder, and salt. Mix well to ensure the spices are evenly distributed.

In another bowl, whisk together eggs, honey, brown sugar, applesauce, melted coconut oil, and vanilla until smooth. Fold in the diced apples.

The apples add natural sweetness and moisture, which keeps the bars tender without needing excessive fat or sugar.

Pour the wet mixture into the dry ingredients and stir until fully combined. Add any optional mix-ins like nuts or dried fruit.

The batter will be thick—this is what helps the bars hold their shape.

Transfer the mixture to the prepared baking dish, spreading evenly with a spatula. Bake at 350°F (175°C) for 25–30 minutes, or until the top is set and lightly golden.

Let cool completely before slicing to prevent crumbling.

Once cooled, lift the bars from the pan and cut into squares or rectangles. Store in the refrigerator for up to 5 days or freeze for up to 2 months.

These bars hold up beautifully for meal prep and don’t dry out easily.
