Ingredients
  

For the Batter
  • 1/2 cup Unsalted Butter Provides moisture and richness; substitute with margarine for a dairy-free option.
  • 1/2 cup Brown Sugar Adds sweetness and a chewy texture; can replace with coconut sugar for a less processed alternative.
  • 1/4 cup Granulated Sugar Enhances sweetness and crispiness; use honey or maple syrup for a natural sweetener but adjust liquid ingredients.
  • 1 large Egg Binds the ingredients together; for vegan options, use 1/4 cup unsweetened applesauce.
  • 1 tsp Vanilla Extract Adds flavor depth; can substitute with almond extract for a different twist.
  • 1 1/4 cups All-Purpose Flour Forms the structure of the bars; gluten-free flour blend can be used as a substitute.
  • 1/2 tsp Baking Soda Helps the bars rise; ensure it's fresh for best results.
  • 1/4 tsp Salt Enhances flavor balance; skip if using salted butter.
For the Mix-Ins
  • 1/2 cup Chocolate Chips Adds richness and melty texture; choose dark or semi-sweet varieties based on preference.
  • 1/2 cup Halloween M&Ms or Candy-Coated Chocolates Contributes color and crunch; substitute with any seasonal candy.
  • 1/4 cup Candy Eyeballs Fun decoration and sweetness; choose non-melting eyeballs for best results.
Optional Toppings
  • Sprinkles or Chopped Candy Bars Enhance visual appeal and add extra fun!

Equipment

  • 8x8-inch baking pan
  • Mixing bowl
  • Electric mixer

Method
 

Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C) and grab an 8x8-inch baking pan. Line the pan with parchment paper, allowing some overhang for easy removal later.
  2. In a large mixing bowl, combine your softened unsalted butter, brown sugar, and granulated sugar. Using an electric mixer, beat together the ingredients on medium speed for about 2-3 minutes, until the mixture appears light and fluffy.
  3. Once your butter and sugars are beautifully creamed, add in one large egg and one teaspoon of vanilla extract. Mix again until the ingredients are smooth and well combined, about 1-2 minutes.
  4. Gradually sift in 1 1/4 cups of all-purpose flour, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt into the wet mixture. Stir gently until just combined.
  5. Gently fold in 1/2 cup of chocolate chips and 1/2 cup of Halloween M&Ms or candy-coated chocolates. Ensure that they are evenly distributed throughout the batter, but save a few for topping.
  6. Spread the batter evenly into your prepared baking pan, making sure it reaches the corners. Press the remaining candy pieces on top for a festive touch. Bake in your preheated oven for 20-25 minutes.
  7. Once baked, remove the pan from the oven and let the Monster Mash Cookie Bars cool completely in the pan. This typically takes about 30 minutes.
