Preheat oven to 350 F. Prepare a square 8-inch by 8-inch baking dish with parchment paper placing it horizontal & vertical hanging over the sides of the dish for easy removal.
Using a hand mixer, beat the eggs whites together in a large bowl until fluffy peaked. Then add the the sugar, vanilla, applesauce, maple syrup and coconut oil to the eggs and beat until combined.
To the batter, fold in the salt and flour. Do not over combine. Transfer the batter to the prepared baking dish and smooth with a spatula or back of a spoon.
Place in the oven and bake at 350 F for 30 minutes until the edges are brown.
While the crust is baking, add the cream cheese and stevia to a bowl and whisk together very well.
After you remove the crust from the oven, spread the cream cheese evenly over it. It should spread easily as the crust is warm.
Next add the strawberry preserves to the top, placing random dollops of it all over. Then using a toothpick swirl the preserves into the cream cheese.
Place in the freezer to set 3-6 hours, overnight is best. When you're ready to eat, simply lift the parchment paper up to remove the bars from the dish and slice into 12 squares.
