Preheat the oven to 350 degrees. In a large mixing bowl, whisk the butter/oil, applesauce, brown sugar, maple syrup, peanut butter, vanilla, eggs, baking powder, salt, and flour. Carefully whisk in the milk. Then, stir in the oats and mini chocolate chips. Next, pour into a greased 9x13 baking dish or 12 lined muffin cups.
In a medium mixing bowl, beat the cream cheese until smooth. Then, beat in the peanut butter, milk/cream, and powdered sugar. Pipe or spread over cooled oatmeal.
Notes
If I add two scoops of protein powder, I only use 1/4 cup of flour.
