Cookie Dough Brownies

Why I’ll Love This Recipe

I enjoy making these brownies because they offer the best of both worlds—chewy brownies and creamy cookie dough in every bite. I appreciate that the cookie dough is completely safe to eat thanks to the heat-treated flour. The recipe is easy to follow, and using a boxed brownie mix saves time without sacrificing flavor. I also like how the colorful M&M’s make these brownies look festive for any celebration.

Ingredients

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

• 16.3 ounces fudge brownie mix (Betty Crocker brand)
• 2 large eggs, room temperature
• ½ cup vegetable oil
• 2 tablespoons water
• 1¾ cups all-purpose flour
• 1 cup salted butter, softened to room temperature
• ¾ cup light brown sugar, packed
• ½ cup granulated sugar
• 1½ teaspoons vanilla extract
• 2 tablespoons heavy cream
• ¼ teaspoon salt
• 1½ cups mini semi-sweet chocolate chips
• ⅓ cup mini M&M’s candies

Directions

1. I preheat the oven to 350°F and line a 9×9-inch straight-sided metal baking pan with parchment paper, leaving enough overhang to lift the brownies later. I lightly spray the pan with baking spray.
2. I prepare the brownie batter by whisking together the brownie mix, eggs, vegetable oil, and water until smooth.
3. I spread the batter evenly into the prepared pan and bake for 30–33 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs.
4. I remove the brownies from the oven, reduce the oven temperature to 300°F, and allow the brownies to cool completely.
5. While the brownies cool, I line a quarter sheet pan with parchment paper and spread the flour evenly over the pan.
6. I bake the flour for 5–7 minutes to heat-treat it, then allow it to cool completely.
7. In a large mixing bowl, I beat together the softened butter, brown sugar, granulated sugar, and vanilla extract until light and fluffy.
8. I mix in the heavy cream and salt until fully combined.
9. I gradually add the cooled, heat-treated flour, mixing just until incorporated.
10. I fold in the mini chocolate chips with a spatula until evenly distributed.
11. Once the brownies are completely cool, I scoop portions of the cookie dough over the brownie layer.
12. Using an offset spatula, I gently spread the cookie dough into an even layer without disturbing the brownies underneath.
13. I sprinkle the mini M&M’s over the top and gently press them into the cookie dough.
14. I refrigerate the brownies for about 30 minutes before lifting them from the pan and slicing into squares.

Variations

I like to customize these brownies depending on the occasion. I sometimes replace the mini M&M’s with chopped peanut butter cups, toffee bits, or crushed chocolate sandwich cookies for a different twist. I also enjoy mixing white chocolate chips, peanut butter chips, or butterscotch chips into the cookie dough. For an extra indulgent dessert, I drizzle melted chocolate or caramel sauce over the top before serving.

Storage/Reheating

I store the brownies in an airtight container in the refrigerator for up to 5 days to keep the cookie dough layer fresh. For longer storage, I wrap individual squares tightly and freeze them for up to 2 months. When I’m ready to enjoy one, I let it thaw in the refrigerator or at room temperature. I usually serve these brownies chilled or slightly softened, so I don’t reheat them.

FAQs

Why do I need to heat-treat the flour?

I heat-treat the flour to eliminate any potential bacteria, making the cookie dough safe to eat without baking.

Can I make these brownies ahead of time?

Yes. I often prepare them a day in advance because chilling helps the cookie dough layer firm up and makes slicing easier.

Can I use homemade brownies instead of a boxed mix?

Absolutely. I can substitute my favorite homemade brownie recipe as long as it’s baked in a 9×9-inch pan.

How do I get clean slices?

I chill the brownies thoroughly before slicing and wipe the knife clean between each cut for neat, bakery-style squares.

Can I freeze Cookie Dough Brownies?

Yes. I wrap each brownie individually and freeze them in an airtight container for up to 2 months. I thaw them before serving for the best texture.

Conclusion

I enjoy making these Cookie Dough Brownies because they’re rich, indulgent, and surprisingly simple to prepare. The fudgy brownie base, creamy edible cookie dough, and colorful candy topping create a dessert that’s perfect for celebrations or anytime I want to treat myself. Every bite delivers the perfect combination of chocolatey goodness and soft cookie dough, making this recipe one I’ll happily make again and again.
