Instructions
- Preheat oven to 350°F. Spray a 13″ x 18″ rimmed sheet pan with non-stick cooking spray. Set aside.
- In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and sugars until well combined. Beat in the eggs and vanilla.
- With the mixer on low speed, beat in the flour, baking soda and salt until combined.
- Divide cookie dough into 6 different mixing bowls (about 3/4 cup per bowl). Mix each cookie dough flavor as follows:
- Monster Mash M&M’s Bars: stir in 1/4 cup semi-sweet chocolate baking chips and 1/4 cup Halloween-colored M&M’s
- Scary S’mores Bars: stir in 1/4 cup graham cracker crumbs, 1/4 cup Hershey’s chocolate barchunks, and 1/4 cup mini marshmallows
- Cookies & Cream “Graveyard” Bars: stir in 3 chopped Halloween Oreos
- Witch’s Brew Peanut Butter Bars: stir in 1/4 cup creamy peanut butter until well combined and then fold in 1/4 cup Reese’s Pieces candies and 1/4 cup broken pretzel sticks
- Candy Corn Blondie Bars: stir in 1/4 cup white chocolate chips and 1/4 cup candy corn
- Nutella Spiderweb Bars: stir in 1/4 cup Nutella chocolate hazelnut spread until well combined and the cookie dough is dark
- Place each ball of mixed cookie dough into a sixth of the prepared sheet pan.
- Press the cookie doughs down evenly, with your hands, to fill the sixth of the sheet pan that each cookie dough is in. Each cookie dough should be pressed up next to the other cookie doughs that are beside it to fill the entire sheet pan.
- Garnish each square of cookie dough as follows:
- Monster Mash M&M’s Bars: garnish with more Halloween-colored M&M’s and Halloween-themed sprinkles
- Scary S’mores Bars: garnish with more mini marshmallows
- Cookies & Cream “Graveyard” Bars: no garnish before baking
- Witch’s Brew Peanut Butter Bars: garnish with more Reese’s Pieces candies
- Candy Corn Blondie Bars: no garnish before baking
- Nutella Spiderweb Bars: no garnish before baking
- Bake for about 15-20 minutes or until golden brown on top and a toothpick inserted in the center of the cookie bars comes out with moist crumbs. Try not to over-bake them if you want them to be chewy.
- Once the cookie bars are baked, let cool for a few minutes and then finish them off as follows:
- Candy Corn Blondie Bars: press whole candy corns into the top of the warm blondie bars
- Scary S’mores Bars: press the candy eyeballs into the melted marshmallows so they stick
- Cookies & Cream “Graveyard” Bars: sprinkle the Oreo cookie bars section with crushed Oreos and then arrange the gummy worms on top of the Oreo “dirt”
- Nutella Spiderweb Bars: let the bars cool for at least 10 minutes and then pipe a spiderweb design onto the Nutella bars section. Create a mini spider with the Oreo and halved pretzel sticks and place it on the spiderweb
- Let the cookie bars cool completely in the pan before cutting into squares and serving. Enjoy!
