How to Make M&M Cookie Dough Fudge Recipe

Step 1: Make the Cookie Dough

Begin by beating together the softened butter, brown sugar, and granulated sugar in a medium bowl until your mixture is light, fluffy, and smelling incredible. This mixture sets the foundation for a tender and flavorful cookie dough.

Step 2: Add Liquid Ingredients

Mix in the milk and vanilla extract until everything is combined and silky smooth, which keeps the dough moist and fragrant.

Step 3: Incorporate the Flour and Salt

Gradually fold in the heat-treated flour and a pinch of salt. The heat treatment of the flour is essential since this dough isn’t baked, ensuring safety without sacrificing texture. Stir until the dough comes together perfectly.

Step 4: Fold in the Mini M&Ms

Gently stir the first 1/2 cup of mini M&Ms into the dough, embedding those colorful bursts that will give every bite a little surprise.

Step 5: Prepare the Fudge Layer

In a medium saucepan over low heat, combine white chocolate chips and sweetened condensed milk. Stir constantly until the chocolate melts completely, transforming into a smooth, glossy mixture that can’t wait to be layered.

Step 6: Add Vanilla to the Fudge

Once off the heat, stir in the vanilla extract for added aroma and sweetness that perfectly complements the cookie dough beneath.

Step 7: Assemble the Fudge

Line an 8×8-inch baking pan with parchment paper, leaving enough overhang so you can lift the fudge out easily. Press the cookie dough evenly into the bottom of the pan, forming a thick, indulgent base layer.

Step 8: Pour the Fudge Layer

Pour the warm, creamy white chocolate fudge gently over the cookie dough, spreading it out to the edges for an even, luscious coat.

Step 9: Add Toppings

Sprinkle the remaining mini M&Ms on top of the fudge while it’s still warm, pressing them in lightly so they stay put and add that extra pop of color and crunch.

Step 10: Chill and Slice

Let your M&M Cookie Dough Fudge Recipe cool at room temperature for about 30 minutes, then move it to the refrigerator for at least two hours to set fully. Once firm, lift it out using the parchment paper and slice into 16 irresistible squares.

How to Serve M&M Cookie Dough Fudge Recipe

Garnishes

A simple dusting of powdered sugar or a drizzle of melted chocolate over each square can make them feel even more special without overwhelming the fudge’s sweet charm. Fresh berries can also bring a nice, tart contrast if you prefer a hint of fruitiness.

Side Dishes

This fudge pairs beautifully with a cold glass of milk for classic comfort, or with a scoop of vanilla ice cream to make it feel like a decadent dessert extravaganza. Coffee lovers will find their perfect match with a hot espresso or creamy latte on the side.

Creative Ways to Present

For parties, serve squares on a decorative platter sprinkled with extra mini M&Ms or chopped nuts. Wrap a few squares in parchment paper tied with twine to create charming edible gifts. Layering them in mason jars separated by wax paper pieces can also make a lovely to-go treat.

Make Ahead and Storage

Storing Leftovers

Store any leftover fudge in an airtight container at room temperature for up to 3 days, or in the fridge to keep it fresher and firmer longer, up to a week. Just make sure to avoid humid conditions to prevent the fudge from becoming sticky.

Freezing

If you want to keep your M&M Cookie Dough Fudge Recipe around longer, wrap individual squares in plastic wrap and place them in a freezer-safe container. Frozen fudge maintains its quality for up to 3 months and thaws quickly at room temperature.

Reheating

Fudge is best enjoyed chilled or at room temperature, but if you prefer it softer, let it sit out until it warms up naturally. Avoid microwaving because it can melt unevenly and make the texture grainy rather than delightfully creamy.

FAQs

Can I use regular flour instead of heat-treated flour?

Since the cookie dough isn’t baked, it’s important to use heat-treated flour to avoid any risk of bacteria. You can heat-treat regular flour at home by spreading it on a baking sheet and baking it at 350°F (175°C) for about 5 minutes.

Is it possible to substitute white chocolate chips with another type of chocolate?

Yes! While white chocolate provides a creamy sweetness, semi-sweet or milk chocolate chips work well too if you want a richer, deeper chocolate flavor. Just keep an eye on the melting process as different chocolates melt differently.

Can I use peanut M&Ms or other varieties?

Absolutely! Peanut M&Ms or any other types add a unique crunch and flavor, but keep in mind that the texture and taste will shift accordingly. Make sure to chop larger candy pieces to evenly disperse throughout the dough and on top.

How long can the fudge sit at room temperature?

It’s safe to leave the fudge out for a few hours during serving. However, for best flavor and texture, it’s advisable to store it in the refrigerator if it will be longer than 3-4 hours, especially in warm climates.

Can I make this recipe vegan or dairy-free?

This particular recipe relies on dairy ingredients, but you could experiment with vegan butter, non-dairy milk, and dairy-free white chocolate to create a vegan-friendly version. Just be aware that texture and flavor might vary.
