Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Cookie Dough Fudge Layer:

1/2 cup unsalted butter, softened
1/2 cup brown sugar, packed
1 teaspoon vanilla extract
1/4 teaspoon salt
1 cup all-purpose flour (heat-treated)
1 can (14 oz) sweetened condensed milk
2 cups white chocolate chips, melted

For the Chocolate Topping:

1 1/2 cups milk chocolate chips (or semi-sweet)
1 tablespoon vegetable oil or coconut oil
1/2–3/4 cup M&Ms, for topping

To Heat-Treat the Flour (for safety):
Spread flour on a baking sheet and bake at 350°F (175°C) for 5 minutes. Allow it to cool completely before using.

Directions

Line an 8×8 or 9×9-inch baking dish with parchment paper.
In a large bowl, cream together the softened butter and brown sugar until smooth.
Mix in vanilla extract and salt until fully incorporated.
Add the cooled, heat-treated flour and stir until combined.
Pour in the sweetened condensed milk and mix until the batter becomes thick and smooth.
Melt the white chocolate chips in 20-second microwave bursts (or use a double boiler).
Quickly fold the melted white chocolate into the mixture until smooth and well-blended.
Spread the mixture evenly into the prepared baking dish and smooth the top.
In another bowl, melt the milk chocolate chips with oil in 20-second intervals until smooth.
Pour the melted chocolate over the fudge layer, spreading evenly.
Sprinkle M&Ms evenly across the top.
Refrigerate for 2–3 hours or until the fudge is firm.
Lift the fudge out of the dish using parchment paper edges and cut into squares.

Variations

Peanut-Free Version: Use candy-coated chocolate pieces instead of M&Ms if you’re avoiding peanuts.
White Chocolate Swirl: Swirl extra melted white chocolate on top before chilling for a marbled effect.
Dark Chocolate Topping: Substitute milk chocolate with dark chocolate for a richer, less sweet flavor.
Add Nuts: For a crunchy twist, fold in chopped almonds or walnuts into the cookie dough mixture.
Holiday Version: Use seasonal M&Ms to make it festive for Christmas, Easter, or Halloween.

Storage/Reheating

Store the fudge in an airtight container in the refrigerator for up to 2 weeks. For longer storage, freeze for up to 3 months, placing parchment paper between layers to prevent sticking. Thaw in the fridge before serving. Fudge is best enjoyed chilled or at room temperature — no reheating needed.

FAQs

1. Can I use dark chocolate instead of milk chocolate for the topping?
