Ingredients

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

1 cup all‑purpose flour (heat treated for safety)

2 cups semi‑sweet chocolate chips (divided)

½ cup salted sweet cream butter, softened

⅓ cup light brown sugar, packed

¼ cup granulated sugar

2 tablespoons milk

1 teaspoon vanilla extract

¼ teaspoon salt

14 oz can sweetened condensed milk (do not substitute evaporated milk)

1½ cups white chocolate chips

Directions

I line an 8×8-inch baking dish with parchment paper and give it a light spray with nonstick spray.

I heat-treat the flour by microwaving it in a microwave-safe bowl for 1 minute, then let it cool completely before sifting to remove clumps.

Next I place 1 cup of the semi-sweet chocolate chips in a Ziploc bag and freeze them while I prepare the rest.

Using a handheld mixer, I cream together the butter, granulated sugar, brown sugar, milk, vanilla, and salt for about 1½ to 2 minutes.

I reduce the mixer speed and add in the cooled flour, mixing until just combined.

In another microwave-safe bowl, I heat the white chocolate chips and sweetened condensed milk in 30-second bursts, stirring between each, until the mixture is smooth.

I stir the frozen chocolate chips into the cookie dough mixture, then gently fold in the white chocolate fudge mixture until combined.

Then I spread everything into the prepared dish, sprinkle the remaining chocolate chips on top, and press them down gently.

I cover and refrigerate the dish for at least 2 hours or overnight, until the fudge is fully set.

I cut the fudge into about 25 squares and serve them chilled.

Variations

I sometimes swap semi-sweet chocolate chips with dark or milk chocolate depending on what I have on hand.

For a nutty twist, I like to fold in chopped walnuts or pecans.

I’ve tried adding mini M&M’s for a more colorful, festive version — great for kids’ parties.

Swapping the white chocolate chips with butterscotch or peanut butter chips gives it a completely different flavor profile.

A sprinkle of sea salt on top adds a sweet-salty finish I enjoy.

Storage/Reheating

I store these fudge squares in an airtight container in the refrigerator for up to one week. For longer storage, I freeze them between layers of parchment paper and they keep well for up to 2 months. I don’t reheat them since they’re best served chilled.

FAQs

What does it mean to heat-treat flour?

Heat-treating flour kills any potential bacteria. I microwave it for about 1 minute or bake it at 350°F for 5–10 minutes to make it safe for no-bake recipes like this one.

Can I use evaporated milk instead of sweetened condensed milk?

No, I don’t recommend that. Evaporated milk lacks the sweetness and thickness needed for the fudge layer to set properly.

Do I have to chill it overnight?

At minimum, I chill the fudge for 2 hours, but I’ve found that chilling overnight gives the best texture and helps it hold its shape when cut.

Can I make this dairy-free?

Yes, I can substitute plant-based butter, non-dairy milk, and dairy-free chocolate chips. I also use coconut condensed milk as a swap for the sweetened condensed milk.

Why did my fudge not set properly?

If the fudge is too soft, I might not have chilled it long enough, or the ratio of white chocolate to condensed milk may have been off. It’s important to measure carefully and give it ample chill time.

Conclusion

These Cookie Dough Fudge Squares are a no-bake dream come true — easy to make, rich in flavor, and always crowd-pleasing. I love keeping a batch in the fridge for impromptu treats or party trays. Whether I’m making them for family, friends, or just myself, they’re always a sweet success.
