Ingredients

Scale

Oatmeal Layers

  • 1/2 cup unsalted butter, melted
  • 1/2 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 1 cup + 2 tablespoons all-purpose flour
  • 1/4 teaspoon salt
  • 1/2 teaspoon cinnamon
  • 1 and 1/3 cups old-fashioned oats

Chocolate Fudge

  • 1 and 1/4 cups semi-sweet chocolate chips or 5070% dark chocolate
  • 1 cup sweetened condensed milk (one 14-oz can)
  • 2 tablespoons unsalted butter

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving an overhang on the edges for easy removal, or alternatively, line with aluminum foil and lightly grease.
  2. Make the oatmeal cookie layer: In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Add in the egg and vanilla extract, whisking until fully incorporated. Fold in the flour, salt, and cinnamon, then gently incorporate the old-fashioned oats until combined.
  3. Form the bottom layer: Spoon about three-quarters of the oatmeal mixture evenly into the prepared baking pan and spread it out to create a smooth, even layer. Reserve the remaining oatmeal mixture for topping.
  4. Prepare the chocolate fudge layer: Fill a medium saucepan with about 1/2 inch of water and bring it to a low simmer over low to medium heat. Place a large heatproof glass bowl over the saucepan, ensuring that the bowl bottom does not touch the water.
  5. Melt fudge ingredients: Add the chocolate chips, sweetened condensed milk, and butter to the bowl. Stir gently as they melt together until the mixture is smooth and glossy. Remove the bowl from heat once fully melted.
  6. Assemble the bars: Pour the melted chocolate fudge mixture evenly over the oatmeal cookie layer in the pan. Using the reserved oatmeal mixture, drop small tablespoon-sized dollops over the fudge layer so that some chocolate remains visible between the pieces.
  7. Bake the bars: Place the baking pan in the preheated oven and bake for 25 to 30 minutes. The oatmeal cookie pieces on top should look set but not browned excessively. Baking longer will make the bars crispier and less chewy.
  8. Cool and slice: Allow the bars to cool completely at room temperature for about 3 hours. Use the parchment or foil overhang to lift the bars out of the pan. Transfer to a cutting board and slice into 16 equal bars with a sharp knife.

Notes

  • For a thinner, less rich chocolate fudge layer, reduce the fudge ingredients to 3/4 cup plus 2 tablespoons chocolate chips, 3/4 cup sweetened condensed milk, and 1 1/2 tablespoons unsalted butter.
  • Store the bars in an airtight container at room temperature for up to 4 days.
  • Nutrition information provided is an estimate based on dividing the pan into 16 bars.
