Servings

Ingredients

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

Instructions
 

Prepare the pan and preheat the oven:

  1. Preheat the oven to 350°F (175°C). Butter the bottom and sides of a 9x9-inch square baking pan. Line the bottom with a piece of parchment paper, allowing it to extend over two sides for easier removal.

Toast the oats and coconut:

  1. In a medium bowl, combine the oats and shredded coconut. Spread the mixture onto a baking sheet and bake for 10 to 12 minutes, stirring once or twice, until lightly browned. Remove from the oven and transfer to a large mixing bowl.

Combine dry ingredients:

  1. To the toasted oat mixture, add the all-purpose flour, graham cracker crumbs, salt, and ground cinnamon. Stir to combine thoroughly.

Prepare the syrup mixture:

  1. In a medium saucepan over medium heat, combine the butter, brown sugar, and maple syrup. Bring the mixture to a boil, stirring frequently. Allow it to boil for 1 minute, then remove from heat and stir in the vanilla extract.

Combine and press the bottom layer:

  1. Pour the hot syrup mixture over the dry ingredients and stir until all dry ingredients are evenly coated. Transfer half of the mixture into the prepared baking pan and press it evenly into the bottom using parchment paper or the back of a spoon. Allow to cool for 5–10 minutes.

Add chocolate and marshmallows:

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

Top with remaining oat mixture:

  1. Distribute the remaining oat mixture over the chocolate and marshmallows. Press down gently to ensure the top layer adheres.

Bake and cool:

  1. Bake in the preheated oven for 15 minutes, or until the top is lightly golden. Remove from the oven and allow to cool in the pan on a wire rack for 20–30 minutes.

Cut and serve:

  1. Once completely cooled, lift the bars from the pan using the parchment paper overhang. Cut into squares and serve. Store in an airtight container at room temperature.

Notes

To make these S’More Granola Bars gluten-free, substitute the all-purpose flour with a 1:1 gluten-free flour blend and use certified gluten-free oats. Replace the graham cracker crumbs with gluten-free graham-style crumbs or crushed gluten-free digestive biscuits. Ensure that all remaining ingredients, particularly chocolate chips and marshmallows, are labeled gluten-free and processed in a certified gluten-free facility to avoid cross-contamination.
