Oatmeal fudge bars are a delicious combination of an oatmeal cookie with a fudgy, chocolate center. These are always a hit with family and friends.

Oatmeal fudge bars are chewy, fudgy cookie goodness. I have a serious sweet tooth especially anything that involves chocolate like chocolate cherry cake, chocolate crispy treats, or chocolate chip bundt cake.

Ingredients needed

  • Oatmeal – Old fashioned oatmeal
  • Flour – All purpose flour
  • Brown sugar – Light brown sugar
  • Chocolate chips – Semi-sweet chocolate chips
  • Butter – Unsalted butter slightly softened.
  • Eggs – 2 large eggs
  • Baking soda – This helps the cookie bars to rise.
  • Vanilla extract – Adds a hint of warm sweetness.
  • Salt – Balances out the sweetness.
  • Sweetened condensed milk – This is used for the creamy fudge center

How to make oatmeal fudge bars

  1. Start by preheating your oven to 350 degrees F. Prepare a 9 x 13 brownie pan by either spraying with non-stick cooking spray or line with parchment paper and then lightly spray with cooking spray.
  2. Cookie dough: Beat brown sugar and softened butter in a mixing bowl.
  3. Mix in the eggs and vanilla extract.
  4. Mix in the flour, baking soda, and salt.
  5. Fold in oatmeal into the cookie batter.
  6. Spread 2/3 of the batter in the prepared brownie pan.
  7. Fudge center: Place the chocolate chips, sweetened condensed milk, butter, vanilla extract, and salt in a saucepan.
  8. Stir and melt over medium heat being careful not to burn.
  9. Spread the fudge mixture over the batter in the pan and then top with the remaining oatmeal cookie dough mixture.
  10. Bake for 30 minutes. Let cool before cutting and serving.
Steps to make oatmeal bars

Recipe tips

  • You can use quick or old fashioned oats for these bars but be sure not to use instant oatmeal. The instant oatmeal is too fine and doesn’t work well for baking.
  • Make it easy to cut the bars by lining the baking pan with parchment paper.
  • Be sure not to over mix the cookie dough.

How to store leftover oatmeal fudge bars

Store: Make sure to let the oatmeal bars completely cool before storing in an airtight container. They can sit out at room temperature for up to 4-5 days.

Freeze: These bars can be frozen for up to 3 months. Store them in a freezer safe bag or container. Thaw at room temperature.

    Kids love this – perfect combo of fudge and oatmeal! We switched up and put in half steel cut oats and rolled oats for an added crunch

  2. The first item in your Recipe is “Cookie”, what is this. I live in Ireland, in US you sometimes use different names for items we may have under another name.
    Can you please tell me, sorry about that.

    1. Hi Ursula,

      Cookie just means the dough part of the oatmeal fudge bars. There is a dough layer, fudge layer and then topped with dough layer. Hope that helps.

  3. The best part about healthy dessert recipes, like these whole wheat oatmeal fudge bars, is that they still taste decadent and comforting, and my kids don t know the difference.

    1. Lol with over 500 calories o per serving I don’t know if I’d call these “healthy “ good yes !!!!this would be a Slpurge 😂😂😂
