Ingredients

For the Oatmeal Cookie Layers

  • 1 cup unsalted butter, softened
  • 2 cups brown sugar, packed
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 ½ cups old-fashioned oats
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt

For the Fudge Filling

  • 1 can (14 oz) sweetened condensed milk
  • 2 cups semi-sweet chocolate chips
  • ½ cup unsalted butter
  • 1 teaspoon vanilla extract
  • ¼ teaspoon salt

Instructions

Prepare the Oven & Baking Pan

Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

Make the Oatmeal Cookie Dough

  1. In a large mixing bowl, beat the butter and brown sugar together until smooth and creamy.
  2. Add the eggs and vanilla extract, mixing until fully combined.
  3. In a separate bowl, whisk together the oats, flour, baking soda, and salt.
  4. Gradually mix the dry ingredients into the wet mixture until combined. The dough will be thick and sticky.

Prepare the Fudge Filling

  1. In a medium saucepan, combine sweetened condensed milk, chocolate chips, and butter.
  2. Cook over medium-low heat, stirring constantly, until the chocolate is fully melted and smooth.
  3. Remove from heat and stir in vanilla extract and salt.

Assemble the Oatmeal Fudge Squares

  1. Spread ⅔ of the oatmeal mixture evenly into the prepared baking pan.
  2. Pour the warm fudge filling over the oatmeal layer, spreading it evenly.
  3. Crumble the remaining oatmeal dough on top of the fudge layer, leaving some spaces for the chocolate to peek through.

Bake & Cool

  1. Bake for 25–30 minutes, or until the top is golden brown and set.
  2. Allow the bars to cool completely before slicing to ensure the fudge layer firms up.
  3. Once cooled, cut into squares and enjoy!

Tips for the Best Oatmeal Fudge Squares

  • Use Old-Fashioned Oats: These provide the best texture. Avoid quick oats, as they may make the bars too soft.
  • Don’t Overbake: The bars will continue to firm up as they cool. Removing them from the oven while slightly soft ensures a chewy texture.
  • For Extra Flavor: Add ½ cup chopped walnuts or pecans to the oatmeal dough for crunch.
  • For a Sweeter Twist: Use milk chocolate chips instead of semi-sweet for a sweeter, milder chocolate flavor.
  • To Make It Dairy-Free: Use dairy-free chocolate chips and coconut oil or vegan butter instead of regular butter.

How to Store Oatmeal Fudge Bars

At Room Temperature

  • Store in an airtight container for up to 4 days.

In the Refrigerator

  • Keep refrigerated for up to a week for the best texture.

Freezing Instructions

  • Wrap individual bars in plastic wrap and store in a freezer-safe bag.
  • Freeze for up to 3 months.
  • To serve, thaw at room temperature or warm slightly in the microwave.
