Follow these simple steps to create your delicious Baked Oatmeal Bars:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking dish (9×9 inches) with parchment paper or grease it lightly.

2. Mix Dry Ingredients: In a large bowl, combine the rolled oats, baking powder, cinnamon, and salt. Stir well to ensure even distribution.

3. Combine Wet Ingredients: In another bowl, whisk together the milk, honey or maple syrup, eggs, and vanilla extract until nicely blended.

4. Combine Dry and Wet Mixtures: Pour the wet mixture over the dry ingredients and stir gently until everything is combined.

5. Add Fruits and Nuts: Fold in the chopped fruits, nuts, and chocolate chips if you’re using any.

6. Transfer to Baking Dish: Pour the combined mixture into your prepared baking dish, spreading it out evenly with a spatula.

7. Bake: Place in the preheated oven and bake for 25-30 minutes or until the bars are set and golden on the edges. A toothpick inserted in the center should come out clean.

8. Cool: Remove from the oven and allow the bars to cool in the baking dish for about 10-15 minutes before carefully lifting them out (if using parchment paper) to cool completely on a wire rack.

9. Cut Into Bars: Once completely cool, cut into squares or rectangles according to your preference.

10. Store or Serve: Enjoy your Baked Oatmeal Bars immediately or store them in an airtight container for later.
