Ingredients

Here’s what you’ll need to create these delightful Monster Mash Cookie Bars:

• 1 cup unsalted butter, softened (trust me, it makes all the difference!)
• 1 1/4 cups brown sugar, packed
• 3/4 cup granulated sugar
• 2 large eggs
• 2 teaspoons vanilla extract
• 3 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup chocolate chips (your favorite type)

• 1/2 cup chopped nuts (optional, but adds a great crunch!)

Step-by-Step Instructions

Ready to get baking? Let’s mash those monsters!

1. Preheat your oven: Preheat your oven to 350°F (175°C) and grease or line a 9×13 inch baking pan with parchment paper. This makes it super easy to lift out the bars later!
2. Mix that butter and sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until it’s light and fluffy—about 2-3 minutes. You’ll know it’s ready when it looks like a warm, buttery cloud!
3. Add in the eggs and vanilla: Crack in the eggs one at a time, mixing well after each addition. Then stir in that lovely vanilla extract. The aroma will waft through your kitchen and might just attract some little helpers!
4. Combine the dry ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring until combined. Watch out for overmixing; we want these bars to be chewy, not dense!
5. Fold in the goodies: Now for the fun part! Gently fold in the chocolate chips, colorful candies, and chopped nuts (if using). The vibrant colors will remind you of a spooktacular Halloween night!
6. Spread it out: Pour the cookie dough into the prepared baking pan. Use a spatula to evenly spread the mixture, ensuring that the bars will bake uniformly. P.S. This dough is super tasty—you might want to sneak a bite!
7. Bake: Pop the baking pan into the oven and let it bake for 25-30 minutes. You’ll know they’re done when they’re lightly golden around the edges and a toothpick inserted in the center comes out with just a few crumbs. Everyone in your house is going to wonder what that heavenly smell is!
8. Cool and cut: Once baked, remove the bars from the oven and allow them to cool in the pan for about 10-15 minutes. Then lift them out using the parchment paper and let them cool completely on a wire rack. Once cooled, slice them into squares—but don’t be surprised if the first ones disappear before you can even plate them!

Pro Tips & Variations

Feeling a little adventurous? Here are some tips and variations to make these Monster Mash Cookie Bars uniquely yours:

• Add spices: For a warm twist, consider adding a teaspoon of cinnamon or pumpkin spice to the dry ingredients.
• Switch it up: Swap chocolate chips for white chocolate or butterscotch chips. You can even add crushed Oreos or peanut butter cups for a delicious twist!
• Make it spooky: Decorate your bars with frosting or edible glitter to give them a festive Halloween touch!
• Diet-friendly options: For a healthier version, use coconut oil instead of butter and whole wheat flour instead of all-purpose flour.

Serving Suggestions

These Monster Mash Cookie Bars are perfect for any gathering! I love serving them up warm with a scoop of vanilla ice cream on top—yes, please! Or perhaps enjoy them with a hot cup of apple cider while curled up on the couch during a movie night. You can even pack them into lunch boxes or as a sweet treat for school. The colorful candies peek through, creating an eye-catching snack that kids adore.

Storage Tips

To keep these delightful bars fresh:

• Refrigeration: Store the cookie bars in an airtight container in the refrigerator for up to a week. When you get a sweet craving, just pop one in the microwave for a few seconds to warm it up!
• Freezing: Want to make a big batch ahead of time? Wrap the cooled bars tightly in plastic wrap, then place them in a freezer-safe container for up to three months. Perfect for a last-minute treat or a surprise for guests!
• Reheating: To reheat frozen bars, simply thaw them in the fridge overnight and warm them in the microwave or oven briefly before serving.

FAQs

Can I use different candies in the recipe?

Absolutely! The beauty of Monster Mash Cookie Bars is their versatility. Feel free to include your favorite candies—everything from gummy bears and gummy worms to crushed candy corn can add a fun twist. Just make sure to chop larger candies into smaller pieces for even distribution.

Can I make this recipe gluten-free?

You bet! You can easily substitute the all-purpose flour with a gluten-free flour blend. Just ensure your chocolate chips and any extras are also gluten-free if necessary. Your cookie bars will still be equally delicious!

How do I know when my cookie bars are done baking?

The best way to check is by watching the edges. They should be slightly golden brown, and a toothpick inserted in the center should come out with just a few moist crumbs. If it comes out with wet batter, they need a few more minutes. Just keep an eye on them!

Can I double the recipe?

Sure! If you’ve got a crowd to please, go ahead and double the ingredients, and bake the mixture in two separate pans. Just remember that baking time might vary slightly, so keep an eye on them for doneness!
