Preheat oiven to 350 degrees and line an 8 inch square pan with parchment paper allowing a 1-inch edge to hang over the sides.
First combine oats, sugar, baking powder, cinnamon and salt in a large bowl.
In a seperate bowl, whisk eggs, milk, applesauce, oil and vanilla extract.
Combine the egg mixture with the oat mix. Stir in the chocolate chips. Let the mix rest for 15 minutes to allow the oats to absorb some of the liquid.
Next press mix into prepared baking pan in an even layer.
Then, in a small bowl, whisk toppings together and sprinkle over top.
Bake for 30 minutes or until edges of the bars are golden brown.
Remove from the oven and allow to rest for 15 minutes. Lift bars out of pan using parchment and set on a flat surface. Let them cool completely and then cut into in bars.
Finally, store in an airtight container for 3 days on the counter or 1 week in the refrigerator.
