  1. Bake The Brownies: Whisk together the brownie mix, eggs, oil, and water until the batter is smooth. Spread in the pan and bake at 350 degrees Fahrenheit for 30-33 minutes. Cool completely on the counter.
  2. Heat Treat The Flour: Bake the flour at 350 degrees Fahrenheit for 5-7 minutes then let it cool completely on the counter.
  3. Create The Cookie Dough: Beat the butter, both sugars, and vanilla extract until light and fluffy. Add the heavy cream and salt and mix until fully incorporated. Mix in the cooled flour, ½ cup at a time, then stir in the chocolate chips.

How To Heat Treat Flour

To heat treat the flour in the oven, simply spread it over a baking pan and bake it at 350 degrees Fahrenheit for 5-7 minutes. Allow the heat-treated flour to cool to room temperature, for about 15 minutes. Do not overcook the flour or it will take on a burnt taste.

You can also heat treat your flour in the microwave. Place the flour in a microwave-safe dish and microwave it for 1 minute and 15 seconds at the highest setting, making sure to stir after every 15-second interval (5 times), let it cool, then use it in this recipe.

  • I like to line my pan with parchment paper so you can easily remove the brownies from the pan to slice.
  • Your brownies are done baking when a toothpick inserted into the center comes out just barely clean. A couple of moist crumbs are okay, as you do not want to overbake your brownies or they will be tough.
  • If you have a favorite homemade fudge brownie recipe, you can certainly use it for this recipe in place of the boxed brownie mix. You do not want to use a “cake-like” brownie recipe for this recipe, though.
  • You may want to let the refrigerated brownies warm to room temperature before serving to allow the brownie layer to soften slightly.
  • Since this cookie dough does not contain any leavening ingredients, it is not recommended to bake it into cookies. 
  • Make sure that your butter has softened to room temperature to properly cream with the sugar.
  • To Store: These cookie dough brownies should be stored in an airtight container in the refrigerator for 4-5 days.
  • To Freeze: These brownies can be frozen, tightly wrapped in aluminum foil, for up to 1 month. Thaw the brownies completely in the refrigerator before serving.

Frequently Asked Questions

What is the best brand of brownie mix to use for this recipe?

Betty Crocker brand fudge brownie mix was used to develop this recipe, and the box calls for 2 eggs, ½ oil, and 2 tablespoons water. If the brand of boxed fudge brownie mix you are using calls for different amounts of these ingredients, you will need to follow the directions and ingredients called for on the box of your brand of brownie mix. You will also bake as directed for a 9×9 metal pan.

Why does the flour have to be pre-treated?

The reason the flour is heat-treated is to kill bacteria and pathogens that can find their home in the raw flour. This bacteria can be very harmful, as seen by an outbreak of E. Coli linked to raw flour in 2016.
Heat treating flour can also improve texture and digestibility. While you won’t necessarily get sick by eating raw flour every time, it’s better to be safe than sorry because it is always a possibility. Source

Is it safe to eat raw cookie dough?

Traditional raw cookie dough is not safe to eat. The raw egg and uncooked flour have a high likelihood of containing contaminants like Salmonella and E. coli. This eggless cookie dough recipe does not contain any eggs and I pre-treat the flour by baking it prior to mixing it into the dough, which makes it completely safe to consume.

Prep Time 15 minutes

Ingredients
  

Brownie layer

  • 16.3 ounces box of fudge brownie mix Betty Crocker brand
  • 2 large eggs room temperature
  • ½ cup vegetable oil
  • 2 tablespoons water

Cookie dough layer

  • cups all-purpose flour

  • ¾ cup light brown sugar packed
  • ½ cup granulated sugar
  • teaspoons vanilla extract
  • 2 tablespoons heavy cream
  • ¼ teaspoon salt
  • cups mini semi-sweet chocolate chips
  • cup mini m&m’s candies

Instructions
 

  • Preheat oven to 350°F. Line a 9×9 straight-sided metal baking pan with a piece of parchment paper, leaving enough of the parchment paper to overhang the sides of the pan, then spray the pan with baker’s spray. Set aside.

  • Spread the brownie batter into an even layer in the prepared baking pan. Bake for 30-33 minutes or until a toothpick inserted into the center comes out just barely clean. A couple of moist crumbs are okay, as you do not want to overbake your brownies, or they will be tough.
  • Remove the baked brownies from the oven and reduce the oven temperature to 300°F. Allow the brownies to cool completely on the counter. While the brownie layer is cooling, you can make the cookie dough layer.
  • Line a 9×13 quarter sheet pan with parchment paper. Spread out the all-purpose flour into an even layer on the prepared sheet pan and bake for 5-7 minutes. This is heat treating the flour to kill any potential bacteria. Keep a close eye on the flour, as you do not want it to burn.
    1¾ cups all-purpose flour
  • Remove the heat-treated flour from the oven and let it cool completely on the counter. Once cooled, it can be added to the remaining ingredients.
  • In a large mixing bowl, using a hand mixer on medium speed, beat the butter, light brown sugar, granulated sugar, and vanilla extract for 1-2 minutes or until light and fluffy.
    1 cup salted butter, ¾ cup light brown sugar, ½ cup granulated sugar, 1½ teaspoons vanilla extract
  • Lower the mixer speed to low and add the heavy cream and salt. Mix until the heavy cream is fully incorporated.
    2 tablespoons heavy cream, ¼ teaspoon salt
  • Add the cooled flour, ½ cup at a time, to the cookie dough batter and mix just until incorporated and no white streaks of flour remain.
  • Using a wooden spoon or rubber spatula, stir in the mini semi-sweet chocolate chips until they are evenly distributed in the dough.
    1½ cups mini semi-sweet chocolate chips
  • Once the brownie layer has cooled completely, use a large cookie scoop to scoop the cookie dough out of the bowl and place the scoops evenly over the surface of the brownie layer.
  • Using a small offset spatula, very gently spread the cookie dough into a smooth and even layer. Be careful not to press too hard as you spread the cookie dough as you want to keep the two layers from mixing.
  • Sprinkle the mini M&M’s evenly over the cookie dough layer and gently press them down just enough for them to lay flat and stick to the cookie dough.
    ⅓ cup mini m&m’s candies
  • Refrigerate the cookie dough brownies for 30 minutes. Once the cookie dough has chilled, carefully lift the brownies out of the pan using the overhanging parchment paper and slice to serve.
