Preheat oven to 350 degrees. Line an 8x8 or 9x9 square baking dish with parchment paper and spray with cooking spray. Set aside.
In a large bowl, stir flour, oats, peanut butter, collagen peptides, truvia, brown sugar, salt, baking powder, butter and milk together until moist crumbs form. It will be crumbly and this is totally normal!
Reserve 1 cup of the crumbs and set those aside to use as the crumb topping. To the remaining crumbs, stir with egg white. Press into the bottom of prepared baking dish evenly.
Dollop the top with sugar free jam and then drizzle with peanut butter. Feel free to microwave the peanut butter to get it to drizzling consistency. With remaining crumbs, squeeze together to create larger chunks and sprinkle over the bars.
Bake 15-20 minutes or until edges look golden brown. If you're using an 8x8 pan, they will take a little longer because the bars are slightly thicker.
Cool 15-20 minutes before using the parchment paper to remove completely from pan. Once at room temperature, sprinkle with powdered sugar, cut into 16 even bars and enjoy.
