Lightly grease a 9 x 13 inch sheet pan and preheat the oven to 350. Melt butter and combine oats, walnuts, salt, brown sugar and butter in a bowl. Spread out the oat mixture onto the prepared pan. Bake for 17-20 minutes or until slightly brown and bubble. Let cool completely before adding the toppings.
While the oat crust is cooking, hull and slice the strawberries. Place them in a bowl with the 1 tablespoon of granulated sugar and let sit at room temp until your ready to assemble the bars. Using a mixer or blender (I found that a blender made the mixture really smooth), whip up the cream, then add the cream cheese, powdered sugar and vanilla and blend until smooth and creamy. Top the cooled cookie crust with cream then sliced strawberries.
Refrigerate until ready to serve.
Notes
Coconut Whipped Cream can be subbed for the cream cheese and whipped cream mixture for a dairy free version of these bars. Also, sub coconut oil for the butter. Gluten Free oats should be used if serving these to anyone on a gluten free diet.
