M&M Chocolate Oat Bars – A Delicious Treat for Any Occasion!

Hey there, lovely readers! Today, I’m excited to share with you one of my all-time favorite dessert recipes – M&M Chocolate Oat Bars. These delightful bars are the perfect blend of a brown sugar oatmeal cookie base, a luscious layer of chocolate fudge in the middle, and a colorful topping of M&M’s. They’re not only incredibly scrumptious but also a breeze to make! So, let’s dive right into the recipe.

Preparation is a breeze, with only 10 minutes needed, and baking takes just 25 minutes. You’ll have these mouthwatering bars ready in no time!

Here’s what you’ll need:


  • 1 cup of softened butter
  • 2 cups of brown sugar
  • 2 large eggs
  • 2 teaspoons of vanilla extract
  • 3 cups of old-fashioned oats
  • 2 1/2 cups of all-purpose flour
  • 1 teaspoon of baking soda
  • 1 teaspoon of salt

Fudge Layer

  • 1 package (12 oz) of semi-sweet chocolate chips
  • 1 can (14 oz) of sweetened condensed milk
  • 2 tablespoons of butter
  • 1 teaspoon of salt
  • 1 teaspoon of vanilla extract
  • 1 cup of mini M&M’s


  1. Preheat your oven to 350º F (175º C). Grease or line a 13×9 inch baking dish with parchment paper and set it aside.
  2. In an electric stand mixer, beat together the softened butter and brown sugar until the mixture is light and fluffy. Now, mix in the eggs and vanilla extract, ensuring everything is well combined.
  3. Stir in the old-fashioned oats, all-purpose flour, baking soda, and salt until you have a smooth and uniform mixture.
  4. Press about 2/3rds of the mixture into the bottom of your prepared baking dish to form a firm base.
  5. In a microwave-safe bowl, combine the semi-sweet chocolate chips, sweetened condensed milk, butter, and salt. Microwave this mixture for 1 minute, and then stir it until it becomes smooth and creamy. If needed, heat it in 15-second intervals until it reaches the desired consistency.
  6. Add the vanilla extract to the fudge mixture and stir until well combined. Now, pour this delectable fudge layer over the base mixture in the baking dish, making sure it’s spread evenly.
  7. Crumble the remaining base mixture over the fudge layer, creating a lovely topping for your bars.
  8. Finally, sprinkle the mini M&M’s evenly over the top, adding a burst of color and extra sweetness to your bars.
  9. Bake the bars in the preheated oven for 25-30 minutes, or until they are set and start to turn a beautiful golden brown.
  10. Once they’re done baking, remove the bars from the oven and let them cool completely before serving. Trust me; the anticipation will be worth it!
