Trick or Treat Cookie Bars
August 25, 2026
Chocolate chip cookie bars with a rich Nutella center and limited edition Halloween cookie layer!
There is so much to love about these Trick or Treat Cookie Bars. You’ve got classic chocolate chip cookie dough, a thick layer of Nutella, and chocolate Halloween cookie dough stacked into one seriously spook-tastic bar. Add the pumpkins and sprinkles on top, and they’re so ready for October.
Flavor Profile
The bottom layer has that classic buttery chocolate chip cookie flavor, while the Nutella adds a rich, creamy chocolate-hazelnut center. The chocolate cookie dough on top brings even more chocolate plus little pops of sweetness, and the Reese’s Mini Pumpkins add peanut butter to the mix. They’re rich, gooey, chocolatey, and loaded with different flavors in every layer.
Why You’ll Love This Recipe
- Two different cookie doughs give these bars layers of chocolate chip and chocolatey flavor.
- A gooey Nutella center adds a rich chocolate-hazelnut layer between the cookies.
- Reese’s Mini Pumpkins add the perfect little peanut butter bite on top.
- Halloween sprinkles and pumpkins make the bars colorful and fun without a lot of decorating.
- The thick, soft cookie layers make these extra fun to slice into and see that Nutella center.
The Twist
Instead of making cookie bars with one dough, these have two completely different cookie dough layers with Nutella sandwiched between them. You get classic chocolate chip cookie on the bottom and chocolate Halloween cookie on top, with that gooey Nutella surprise right through the middle.
Ingredient Highlights
- Pillsbury Chocolate Chip Cookie Dough: This makes the classic chocolate chip cookie base. You’ll need one 16.5-ounce package.
- Nutella: Spread it between the two cookie doughs for a creamy chocolate-hazelnut center.
- Nestlé Toll House Trick or Treats Chocolate Cookie Dough: The chocolate top layer has Halloween sprinkles and morsels already mixed into the dough.
- Royal Icing Pumpkins: Add these before baking so they become part of the decorated top.
- Reese’s Mini Pumpkins: Press these into the bars right after baking so they soften slightly without losing their pumpkin shape.
Trick or Treat Cookie Bars
Ingredients
- 1 (16.5-ounce) package Pillsbury Chocolate Chip Cookie Dough
- ¾ cup Nutella
- 1 (14-ounce) package Nestlé Toll House Trick or Treats Chocolate Cookie Dough
- Halloween sprinkles
- Royal icing pumpkins
- Reese’s Mini Pumpkins
Instructions
- Preheat the oven to 350°F. Line an 8×8-inch baking pan with parchment paper and lightly spray with nonstick cooking spray.
- Press the Pillsbury Chocolate Chip Cookie Dough evenly into the bottom of the prepared pan.
- Spread the Nutella evenly over the cookie dough, leaving a small border around the edges.
- Flatten pieces of the Nestlé Toll House Trick or Treats Chocolate Cookie Dough between your hands and arrange them over the Nutella. Gently press the pieces together to create an even top layer.
- Decorate the top with Halloween sprinkles and royal icing pumpkins, gently pressing the pumpkins into the dough.
- Bake for 30–38 minutes, or until the top is set and the edges are golden. Since the bars are thick, the center will stay soft while warm and continue to set as the bars cool.
- As soon as the bars come out of the oven, gently press the Reese’s Mini Pumpkins into the top.
- Let the bars cool completely before lifting them from the pan and cutting into squares.
FAQ
Can I use a different chocolate chip cookie dough?
Yes. Another refrigerated chocolate chip cookie dough will work, but try to use a package close to 16.5 ounces so the thickness of the bottom layer stays similar.
Why do I add the Reese’s Mini Pumpkins after baking?
Adding them after baking helps the pumpkins keep their shape. The heat from the bars will soften them just enough to settle into the top.
Can I leave off the royal icing pumpkins?
Absolutely. They’re mainly there for the Halloween look, so the bars will taste the same without them.
How do I know when these thick cookie bars are done?
Look for golden edges and a top that appears set. The Nutella center and warm cookie dough will make the middle seem very soft at first, so give the bars plenty of time to cool before cutting.
How should I store Trick or Treat Cookie Bars?
Store the cooled bars in an airtight container at room temperature for up to 3 days.
