Whether you’re preparing for a spooky event or just indulging your sweet tooth, these bars are the perfect blend of flavors and textures. Let’s dive into the step-by-step preparation so you can whip them up easily.
Gather All Your Ingredients
Before you even think about turning on the oven, it’s essential to have everything you need ready to go. A well-organized kitchen is key to a smooth baking experience. For Monster Mash Cookie Bars, here’s your shopping list:
- 1 cup unsalted butter, softened
- 1 cup brown sugar, packed
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup chocolate chips
- 1 cup mini marshmallows
- 1 cup festive candy (think Halloween-themed like candy corn or gummy worms)
Make sure to check your pantry for staples. Having everything in one place helps keep the momentum going…and trust me, you don’t want to be mid-recipe when you realize you’re out of chocolate chips!
Prepare Your Baking Pan
While you’re at it, grab a 9×13-inch baking pan and line it with parchment paper. This step is crucial as it makes it much easier to remove the bars once they’re baked. If you don’t have parchment paper, lightly grease the pan with some cooking spray or a little extra butter. This simple act prevents any sticky situations later on.
Cream the Butter and Sugars
Now that your pan is ready, it’s time for one of the most enjoyable steps: creaming your butter and sugars. In a large mixing bowl, beat together the softened butter, brown sugar, and granulated sugar using an electric mixer. If you want to stick to the old-school style, a whisk works fine too, though it may take a little more elbow grease!
You want to mix until the mixture is light and fluffy, which should take about 2-3 minutes. This is important because it incorporates air into your dough, giving your cookie bars a soft texture. It’s all about that fluffy goodness!
Combine Wet Ingredients with the Dry
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Once combined, gradually add this dry mixture to your creamed butter and sugars. Mix well until everything is just combined—overmixing can lead to tough bars, and nobody wants that!
Now, beat in the eggs and vanilla extract until everything is well incorporated. This is where the magic begins, and your kitchen will start filling up with delightful aromas.
Fold in the Fun Ingredients
Your cookie dough is almost complete! The final step before baking is adding in the fun ingredients. Gently fold in the chocolate chips, marshmallows, and Halloween-themed candies. This is your opportunity to get creative. Want more gooey-ness? Toss in an extra handful of chocolate chips or try swapping in peanut butter chips for a fun twist.
Bake and Let Cool
Preheat your oven to 350°F (175°C) and pour your batter into the prepared pan, smoothing the top into an even layer. Bake for about 25-30 minutes, or until the edges are golden brown and a toothpick comes out clean from the center.
Once they’re out of the oven, let your Monster Mash Cookie Bars cool completely in the pan before lifting them out and slicing them up. Patience is a virtue here—you want them firm enough to cut beautifully!
When it comes to Treats & Desserts Monster Mash Cookie Bars, the joy is in the process. So grab some friends, share some stories, and indulge in the sweet delight that you’ve created. These bars aren’t just treats; they’re memories waiting to happen!
