Why you’ll love this recipe

I enjoy this recipe because it is a no-bake treat that comes together with simple steps. The combination of cookie dough base and melted white chocolate creates a soft and creamy texture that I find irresistible.

I also like how visually appealing it is. The mix of regular and mini M&M’s adds color and crunch, making it perfect for parties, holidays, or anytime I want something playful and sweet.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 cup all-purpose flour, spooned and leveled
1½ cups plain M&M’s, divided into 1 cup and ½ cup
1 cup plain mini M&M’s, divided into ½ cup and ½ cup
½ cup salted sweet cream butter, softened
¼ cup granulated sugar
⅓ cup light brown sugar, packed
2 tablespoons half and half
1 teaspoon pure vanilla extract
¼ teaspoon salt
1½ cups white baking chips
14 ounces sweetened condensed milk

Directions

I start by lining an 8×8-inch baking dish with parchment paper and lightly spraying it with nonstick spray.

I place the flour in a microwave-safe bowl and heat it for 1 minute to make it safe to use. Then I let it cool completely and sift out any clumps.

I add 1 cup of regular M&M’s and ½ cup of mini M&M’s into separate bags and place them in the freezer while I prepare the rest.

In a mixing bowl, I cream together the softened butter, granulated sugar, brown sugar, half and half, vanilla extract, and salt for about 1½ to 2 minutes until smooth.

I reduce the mixer speed and add the cooled flour, mixing just until combined. Then I set the mixture aside.

In another heat-safe bowl, I melt the white baking chips with the sweetened condensed milk in the microwave in 30-second intervals, stirring each time until smooth.

I remove the M&M’s from the freezer and stir them into the cookie dough mixture.

Then I add the melted white chocolate mixture into the dough and stir until everything is fully combined.

I spread the mixture evenly into the prepared baking dish.

I sprinkle the remaining M&M’s and mini M&M’s on top and gently press them into the surface.

I cover the dish and refrigerate it for at least 2 hours, or until firm.

Once set, I remove it from the fridge and slice it into 25 squares.

Servings and timing

I get about 25 servings from this recipe. The total time is about 17 minutes of preparation plus at least 2 hours of chilling time.

Variations

I sometimes swap the M&M’s for chocolate chips, peanut butter chips, or chopped candy bars for a different flavor. If I want a peanut butter twist, I mix a few tablespoons of peanut butter into the dough.

For a festive version, I use seasonal-colored candies. I can also drizzle melted chocolate on top for extra decoration.

Storage/reheating

I store the fudge in an airtight container in the refrigerator for up to 1 week. I can also freeze it for longer storage and thaw it in the fridge before serving.

Since this is a chilled dessert, I do not reheat it. I like serving it slightly cold for the best texture.

FAQs

Why do I heat the flour?

I heat the flour to make it safe to eat since it is not baked in this recipe.

Can I skip freezing the M&M’s?

I prefer not to skip this step because it helps prevent the colors from bleeding into the mixture.

Can I use milk chocolate instead of white chocolate?

Yes, I can substitute with milk or dark chocolate, but it will change the flavor and color.

How do I get clean slices?

I use a sharp knife and wipe it clean between cuts for neat squares.

Can I make this ahead of time?

Yes, I like making it ahead since it needs time to chill and set properly.

Conclusion

I love how this monster cookie dough fudge combines fun, color, and rich flavor into one easy dessert. It is simple to prepare, requires no baking, and always turns out delicious. Whether I make it for a gathering or just a sweet treat, it never lasts long.
