How to Make M&M Cookie Dough Fudge Recipe
Step 1: Make the Cookie Dough
Start by beating the softened butter with the brown sugar and granulated sugar in a medium bowl until the mixture is light and fluffy. This creamy base is where the magic of your cookie dough begins.
Step 2: Add Milk and Vanilla
Pour in the milk and vanilla extract, then mix everything until you have a smooth, luscious dough that’s perfectly soft but holds together nicely.
Step 3: Incorporate the Flour and Salt
Slowly add the heat-treated flour and a pinch of salt, stirring continuously until your dough comes together in a thick, edible cookie dough consistency. This step ensures the dough is safe to eat raw and ready to be layered beneath the fudge.
Step 4: Fold in Mini M&Ms
Gently fold in half a cup of mini M&Ms into the cookie dough. These little bursts of color and chocolate will add a festive crunch in every bite.
Step 5: Prepare the Fudge Layer
In a medium saucepan over low heat, combine the white chocolate chips and sweetened condensed milk. Stir constantly until the chocolate melts completely and the mixture looks silky smooth, signaling it’s ready to pour.
Step 6: Flavor the Fudge
Once removed from heat, stir in a teaspoon of vanilla extract to deepen the flavor of the fudge, making it more fragrant and indulgent.
Step 7: Assemble Your Fudge
Line an 8×8-inch baking pan with parchment paper, leaving enough overhang for easy fudge removal later. Press the cookie dough evenly into the bottom of the pan, forming a solid, even layer that will support the fudge on top.
Step 8: Spread the Fudge
Pour the warm white chocolate fudge over the cookie dough layer, spreading it evenly to cover every inch. The contrast of white fudge over golden cookie dough creates a mouthwatering look already.
Step 9: Add a Colorful Finish
Sprinkle the remaining mini M&Ms over the fudge while it is still warm, then gently press them into the surface so they set beautifully into the fudge layer.
Step 10: Chill and Set
Allow the fudge to cool at room temperature for about 30 minutes before transferring it to the refrigerator to chill for at least 2 hours until fully firm. This waiting game is totally worth it for the perfect slice.
Step 11: Slice and Enjoy
Once the fudge has set, lift it out using the parchment paper overhang and cut it into 16 squares. Now you have pieces bursting with cookie dough sweetness and creamy fudge texture to share or savor yourself!
How to Serve M&M Cookie Dough Fudge Recipe

Garnishes
A sprinkle of extra mini M&Ms or a dusting of edible glitter can elevate the look of your fudge. Even a drizzle of melted white or milk chocolate adds a touch of elegance and visual flair, making it perfect for party trays or gifts.
Side Dishes
Serve your M&M Cookie Dough Fudge alongside a tall glass of cold milk for a classic pairing. It also complements coffee or hot chocolate beautifully, making dessert time feel cozy and special during colder days.
Creative Ways to Present
Try placing fudge squares in decorative mini cupcake liners for an adorable bite-sized treat. Alternatively, lay them on parchment paper styled with colorful sprigs of fresh mint or edible flowers to make your presentation pop at gatherings.
Make Ahead and Storage
Storing Leftovers
Keep your leftover M&M Cookie Dough Fudge in an airtight container in the refrigerator. It will stay fresh and chewy for up to one week—perfect for easy grab-and-go treats anytime you need a sweet pick-me-up.
Freezing
If you want to make this fudge ahead for celebrations or gifts, wrap individual squares tightly in plastic wrap and place them in a freezer-safe container. Frozen fudge maintains its flavor and texture well for up to 3 months.
Reheating
This fudge is best enjoyed chilled or at room temperature, but if you prefer it a little softer, let the pieces sit at room temperature for 15 to 20 minutes before serving. Avoid microwaving, as it can melt the cookie dough and fudge unevenly.
FAQs
Can I use regular M&Ms instead of mini M&Ms?
Absolutely! Regular M&Ms will work just fine, but keep in mind they might make the texture a bit chunkier and the fudge heavier. Mini M&Ms offer a more delicate crunch and color distribution.
Is the flour safe to eat raw in this recipe?
Yes, as long as you heat-treat the flour before adding it to the cookie dough. This step kills any harmful bacteria and ensures your cookie dough layer is safe and delicious to eat.
Can I substitute white chocolate chips with milk or dark chocolate?
You can, but it will change the flavor profile and the color of the fudge. White chocolate creates that classic creamy base ideal for this recipe, but milk or dark chocolate can make it richer and more intense if you prefer.
How long does it take for the fudge to set completely?
The fudge needs about 2 hours in the refrigerator to firm up nicely. If you try cutting it too soon, the layers might not hold their shape well.
Can I add nuts or other mix-ins to the cookie dough?
Yes! Chopped nuts, shredded coconut, or even chocolate chips all make wonderful mix-ins. Just be sure not to overload the dough so it still presses evenly into the pan.
Final Thoughts
There is something incredibly joyful about making and sharing the M&M Cookie Dough Fudge Recipe. It’s a nostalgic treat elevated into a simple yet spectacular dessert that always brings smiles.
