Cookie Base:
  • Butter: A rich, creamy foundation that provides tender texture and deep flavor to the bars.
  • Brown Sugar: Adds moisture and a caramel-like sweetness that enhances the overall richness.
  • Eggs: Bind the ingredients together and contribute to the soft, chewy consistency.
  • Vanilla Extract: Introduces a warm, classic flavor that complements the sweet ingredients.
Dry Ingredients:
  • All-Purpose Flour: Creates the structural base for the cookie bars.
  • Baking Powder: Helps the bars rise and achieve a light, soft texture.
  • Salt: Balances the sweetness and enhances the overall flavor profile.
Mix-In Ingredients:
  • Oreo Cookies, M&Ms, White Chocolate Chips, Chocolate Chips: Add delightful crunch, color, and layers of chocolate flavor throughout the bars.
  • Sweetened Condensed Milk: Creates a luscious, gooey ribbon that adds extra moisture and sweetness to the dessert.

Step 1: Prepare Baking Station

Warm up the oven to 350°F. Line a 9×13-inch baking pan with parchment paper, letting extra paper hang over the sides for easy bar removal later.

Step 2: Create Creamy Base

In a large mixing bowl, blend softened butter with brown sugar until the mixture becomes light and fluffy. Slowly mix in eggs and vanilla extract, creating a smooth, rich foundation for the bars.

Step 3: Combine Dry Ingredients

In a separate bowl, sift together flour, baking powder, and salt. Gently fold these dry ingredients into the wet mixture, stirring just until everything is incorporated without overmixing.

Step 4: Add Delightful Mix-Ins

Prepare your fun add-ins:
  • Oreo cookies (roughly chopped)
  • M&Ms
  • White chocolate chips
  • Chocolate chips

Fold these goodies into the batter, distributing them evenly throughout.

Step 5: Spread and Layer

Transfer the batter to the prepared pan, smoothing the surface with a spatula. Create an even layer that promises delicious bites.

Step 6: Drizzle Sweet Surprise

Slowly pour sweetened condensed milk over the batter, allowing it to create beautiful ribbons across the surface.

Step 7: Bake to Perfection

Slide the pan into the preheated oven. Bake for 25-30 minutes, watching for golden-brown edges and a toothpick that comes out with just a few moist crumbs when inserted near the center.

Step 8: Cool and Set

Remove from the oven and let the bars cool completely in the pan for about 1 hour. Patience ensures clean, beautiful cuts.

Step 9: Slice and Serve

Lift the bars out using the parchment paper edges. Slice into squares and serve at room temperature. Watch as everyone devours these indulgent treats!

  • Crush Oreos Perfectly: Break cookies into uneven chunks for varied texture and more exciting bites throughout the bars.
  • Prevent Sinking Toppings: Lightly coat M&Ms and chocolate chips in flour before mixing to help them distribute evenly and stay suspended in batter.
  • Control Sweetness Level: Reduce sweetened condensed milk drizzle by half if you prefer less intense sweetness, maintaining the rich moisture.
  • Ensure Soft Texture: Remove bars from oven when edges are golden but center still looks slightly underbaked for ultra-moist, chewy consistency.
  • Store Smart: Keep bars in an airtight container at room temperature for up to 5 days, separating layers with parchment paper to prevent sticking.
  • Peanut Butter Paradise: Replace white chocolate chips with peanut butter chips and swirl extra peanut butter through the condensed milk layer for rich, nutty flavor.
  • Rocky Road Remix: Mix in chopped almonds, mini marshmallows, and swap some chocolate chips for dark chocolate chunks to create a decadent rocky road-inspired version.
  • Birthday Cake Bonanza: Use birthday cake Oreos, sprinkle colorful rainbow jimmies throughout the batter, and drizzle vanilla glaze on top after cooling for celebratory flair.
  • Salted Caramel Dream: Incorporate sea salt flakes over the top, use caramel-filled M&Ms, and drizzle caramel sauce across the condensed milk layer for a sweet-salty combination.

What Pairs Well with Loaded M&Ms Oreo Bars

  • Indulge with Perfect Pairings
  • Pair with Cold Milk: Creamy, classic milk complements the rich sweetness of the loaded cookie bars, cutting through the intense chocolate flavors and providing a refreshing contrast.
  • Brew Rich Espresso: A bold espresso shot balances the sweetness, bringing out deeper chocolate notes and cleansing the palate between decadent bites of the bar.
  • Serve with Vanilla Bean Ice Cream: Smooth, cold vanilla ice cream creates a luxurious dessert experience, melting gently over the warm cookie bars and enhancing their texture and flavor profile.
  • Match with Caramel Latte: The smooth caramel undertones in a warm latte harmonize with the cookie's sweetness, creating a delightful dessert combination that feels like a cozy indulgence.
  • Store cooled cookie bars in an airtight container with parchment paper between layers to prevent sticking, keeping them fresh for up to 5 days.
  • Wrap individual bars tightly in plastic wrap, then place in a freezer-safe container or ziplock bag, maintaining quality for 2-3 months.
  • Keep bars in a sealed container away from direct sunlight and heat, ensuring they remain soft and delicious for 3-4 days.
  • Place bars on a plate covered with plastic wrap or aluminum foil, protecting them from drying out at room temperature for maximum 2 days.
  • Can I use different types of M&Ms in this recipe?

Yes, you can swap out regular M&Ms for peanut, pretzel, or seasonal varieties to add your own twist to the bars.

  • How do I prevent the bars from being too sweet?

Balance the sweetness by using dark chocolate chips or reducing the amount of sweetened condensed milk slightly.

  • Is it necessary to use parchment paper?

Parchment paper helps with easy removal and prevents sticking, but you can also use a well-greased baking pan as an alternative.

  • Can I make these bars gluten-free?

Substitute the all-purpose flour with a gluten-free flour blend and use gluten-free Oreo cookies to create a gluten-free version of the bars.
