Instructions
Preheat oven to 350 degrees F. Butter the bottom and sides of a 9-by-9-inch square baking pan. Put a long piece of parchment paper in the bottom of the pan, letting the parchment extend up two sides of the pan and overhang slightly on both ends.
In a medium bowl, combine oats and coconut. Spread onto a sheet pan and bake for 10 to 12 minutes, stirring occasionally, until lightly browned. Transfer the mixture to a large mixing bowl and stir in flour, graham cracker crumbs, salt and ground cinnamon.
In a medium saucepan over medium heat, bring the butter, brown sugar, maple syrup and vanilla extract to a boil. Cook and stir for a minute, then pour over the oatmeal mixture, stir well making sure all the dry ingredients are coated with the butter mixture.
Press half of the mixture evenly onto the bottom of the prepared pan using a small piece of parchment paper. Let cool 5-10 minutes.
Once the mixture has cooled, evenly sprinkle with the chocolate chips and marshmallows.
Top with the remaining crust mixture and press gently.
Bake 15 minutes, or until light golden brown. Remove from oven and let cool on a cooling rack for 20 minutes.
