Essential Equipment
Here’s the equipment you’ll need:
- 9-inch square pan: This is the perfect size for these brookies, creating a nice, thick layer.
- Foil: For lining the pan, making it easy to remove the brookies after baking.
- Cooking spray: To prevent the brookies from sticking to the foil.
- Medium bowl: For mixing the sugar cookie dough.
- Offset metal spatula or back of a spoon: For pressing the cookie dough evenly over the brownie layer.
That’s a pretty manageable list of equipment!
List of Ingredients with Measurements
Here’s the ingredient list with precise measurements:
- 1 box Betty Crocker™ Fudge Brownie Mix
- Water, vegetable oil, and eggs (as called for on the brownie mix box)
- 1 pouch (17.5 oz) Betty Crocker™ Sugar Cookie Mix
- Butter and egg (as called for on the cookie mix pouch)
- 1 ¼ cups green M&M’s® milk chocolate candies, divided
- 12 Thins Mint Flavor Creme OREO® Cookies, cut into fourths (about 1 cup)

Step-by-Step Instructions
Let’s break down the process:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Line a 9-inch square pan with foil, allowing the foil to hang over the sides for easy removal. Spray the foil with cooking spray.
- Make the Brownie Layer: Prepare the brownie batter as directed on the box. Spread the batter evenly in the prepared pan.
- Bake the Brownies: Bake for 32 to 35 minutes, or until a toothpick inserted in the center comes out almost clean. The brownies should be set around the edges.
- Cool Slightly: Cool the brownies in the pan for 10 minutes. This allows them to set up a bit before adding the cookie layer.
- Make the Cookie Dough: While the brownies are cooling, prepare the sugar cookie dough as directed on the pouch for drop cookies. Stir in 1 cup of the green M&M’s®.
- Layer the Cookie Dough: Drop half of the cookie dough mixture in chunks on top of the baked brownie layer. Add half of the chopped Mint OREO® Cookie pieces. Repeat with the remaining cookie dough and OREO® pieces.
- Press and Top: Use the back of a spoon or an offset metal spatula to gently press the cookie dough together, forming an even layer. Top with the remaining ¼ cup of green M&M’s®, pressing them gently into the dough.
- Bake Again: Bake for 23 to 28 minutes, or until the cookie layer is set. Cover the pan with foil for the last 10 minutes if necessary to prevent overbrowning.
- Cool Completely: Cool the brookies completely in the pan (at least 2 ½ hours). This is crucial for allowing them to set up properly.
- Cut and Serve: Once cooled, lift the brookies out of the pan using the foil overhang. Cut into 4 rows by 4 rows to create 16 bars.

Troubleshooting
Here are a few potential issues and solutions:
- Brownies Too Gooey: If the brownies are still too gooey after the initial baking time, bake them for a few more minutes before adding the cookie layer.
- Cookie Dough Too Dry: If the cookie dough seems too dry, add a teaspoon or two of milk or water until it reaches the desired consistency.
- Cookie Layer Overbrowning: Cover the pan with foil during the last 10 minutes of baking to prevent overbrowning.
- Brookies Sticking to Foil: Make sure to spray the foil generously with cooking spray before adding the brownie batter.
Tips and Variations
Here are some ways to customize this recipe:
- Different Brownie Mix: Use a different flavor of brownie mix, such as dark chocolate or salted caramel.
- Different Cookie Mix: Use a different flavor of cookie mix, such as chocolate chip or peanut butter.
- Different OREO®s: Use different flavors of OREO®s, such as Golden OREO®s or Birthday Cake OREO®s.
- Different M&M’s®: Use different colors or flavors of M&M’s® to match different holidays or themes.
- Add Nuts: Incorporate chopped nuts, such as walnuts or pecans, into the brownie batter or cookie dough.
- Add Frosting: Once the brookies are cooled, frost them with your favorite frosting, such as chocolate, vanilla, or cream cheese frosting.
