Ingredients

  • 2 c old fashioned rolled oats
  • 1/4 c unsweetened coconut
  • 1/2 c all-purpose flour
  • 1 c graham cracker crumbs or crushed digestive biscuits
  • 1/2 tsp salt
  • 1/4 tsp ground cinnamon
  • 6 tbsp unsalted butter cut into pieces
  • 1/4 c light brown sugar
  • 1/3 c plus 1 tbsp pure maple syrup or golden syrup
  • 1 tsp vanilla extract
  • 1 c semisweet or bittersweet chocolate chips
  • 1 1/2 c mini marshmallows

Instructions

Prepare the baking pan.

  • Preheat the oven to 350°F. Butter the bottom and sides of a 9 x 9-inch square baking pan. Line the pan with a long strip of parchment paper, allowing it to extend up two sides and overhang slightly at both ends.

Toast the oats and coconut.

  • In a medium bowl, combine the rolled oats and unsweetened coconut. Spread the mixture onto a sheet pan and bake for 10 to 12 minutes, stirring occasionally, until lightly browned.

Combine the dry ingredients.

  • Transfer the toasted oat mixture to a large mixing bowl. Stir in the flour, graham cracker crumbs, salt, and ground cinnamon until evenly combined.

Prepare the butter mixture.

  • In a medium saucepan over medium heat, combine the butter, brown sugar, maple syrup, and vanilla extract. Bring the mixture to a boil. Cook, stirring, for 1 minute.

Mix the base.

  • Pour the hot butter mixture over the dry oat mixture. Stir thoroughly until all dry ingredients are evenly coated.

Form the first layer.

  • Press half of the mixture evenly into the bottom of the prepared pan, using a small piece of parchment paper if needed to help flatten the surface. Allow it to cool for 5 to 10 minutes.

Add the filling.

  • Once the base has cooled slightly, evenly sprinkle the chocolate chips and mini marshmallows over the surface.

Add the top layer.

  • Spread the remaining oat mixture over the filling and press gently to create an even top layer.

Bake the bars.

  • Bake for 15 minutes, or until lightly golden brown.

Cool and slice.

  • Remove the pan from the oven and allow the bars to cool on a wire rack for 20 minutes. Cut into squares and serve or store at room temperature.
